f Do not use the emergency braking function to
stop the vehicle when driving normally.
If the electric parking brake could not be applied
fully when the vehicle is stopped, the brake
warning light in the instrument panel starts to
flash.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 139.
Brakes
f Make it a habit to check the operation of your
brakes before driving.
Keep in mind that the braking distance increases
very rapidly as the speed increases. At 60 mph
(100 km/h), for example, it is not twice but four
times longer than 30 mph (50 km/h). Tire traction
is also less effective when the roads are wet or
slippery.
f Therefore, always maintain a safe distance
from the car in front of you.
Vehicles without Porsche Ceramic
Composite Brake (PCCB)
Even though the brake disks consist of alloyed
gray cast iron, they will unavoidably start to
corrode if your car is parked for an extended
period. The brakes will tend to “rub” as a result.
The nature, extent and effects of corrosion
depend on the amount of time the vehicle was
parked, whether road salt or grit was spread and
whether grease-dissolving agents were used in
car washes.
If the braking comfort is noticeably impaired, we
recommend having the brake system checked by
experts at an authorized Porsche dealer.
Brake system function
Your Porsche is equipped with a power assisted
hydraulic dual circuit brake system with disk
brakes at the front and rear.
Both circuits function independently. One brake
circuit operates the front left and rear right wheel
and the other operates the front right and rear left
wheel.
If one brake circuit has failed, the other will still
operate. However, you will notice an increased
pedal travel when you apply the brakes. Failure of
one brake circuit will cause the stopping distance
to increase.
Your vehicle is equipped with an emergency
function in the extreme event of a complete
hydraulic failure of the brake system. If your brake
peddle goes all the way to the floor, do not pump
the brakes.
f Push the brake pedal down firmly and hold it in
that position. A mechanical linkage activates
the second circuit, and you will be able to bring
the vehicle to a stop.
f After bringing your vehicle to a complete stop,
avoid driving the vehicle and instead have it
towed to the nearest authorized Porsche
dealer for repair.

156 Driving and Driving Safety
Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the “On” position (position 1) and verifying that the
warning light illuminates.
The warning light in the instrument panel lights up.
A message will be displayed on the multi-purpose
display of the instrument panel if the brake fluid
level is too low, or (if the brake pedal travel has
increased) one of the two brake circuits has failed.
A greater braking pressure will be required,
stopping distances will be longer and the braking
behavior will change, particularly in curves.
With correctly adjusted brakes and a correctly
working brake system, the pedal travel to the
point of brake application should be 1-3/16 in. to
1-9/16 in. (30 to 40 mm). Whenever the brake
pedal travel exceeds this value, have the brake
system checked.
Brake pedal
Unsuitable or incorrectly fixed floor mats or
objects can reduce the travel of the brake pedal or
prevent you applying the brake pedal.
f Always check the movement of the brake pedal
before driving and make sure that it is not
obstructed by a floor mat or any other object.
f Secure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your authorized Porsche dealer will be glad to
offer you floor mats of the correct size
including a securing possibility.
Information
In case one of the two brake circuits fails,
increased pedal travel is required to bring your
vehicle to a full stop.
f Before descending a steep grade, reduce
speed and shift the transmission into a lower
gear to control speed.
f Do not “ride the brakes” by resting your foot on
the pedal when not intending to apply brake
pressure.
f Do not hold the pedal down too long or too
often. This could cause the brakes to overheat
and lose braking power.
Brake booster
The brake booster assists braking only when
the engine is running.
When the car is moving while the engine is not
running, or if the brake booster is defective, more
pressure on the brake pedal is required to bring
the car to a stop.
Moisture, road salt or grit on brakes affects
braking.
Brakes will dry after a few cautious brake
applications.
Driving through water may reduce the traction.
Moisture on brakes from road water, car wash, or
a coating of road salt or grit may affect braking
efficiency.
f Cautiously apply brakes to test and dry the
brakes after exposure to road water, etc.
The brake booster is ready for operation only
while the engine is running.
If the engine is switched off or there is a defect in
the brake booster, much greater force has to be
applied to the pedal when braking.
f Vehicles with defective brakes must not
be towed and must be transported on a flat
bed.
For information on towing:
f Please see the chapter “TOWING” on
page 302.

Brake wear
Your car has excellent brakes, but they are still
subject to wear. The rate at which they wear
depends on how the brakes are used.
f Have the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the “On” position (position 1) and verifying that the
warning light illuminates.
A warning message will be displayed on the multi-
purpose display of the instrument panel if the
brake pads are worn, excessively.
f Do not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
For information on warning messages on the
multi-purpose display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 139.
Brake pads and brake disks
Wear on the brake pads and brake disks depends
to a great extent on the driving style and the
conditions of use and therefore cannot be
expressed in actual miles on the road.
The high-performance brake system is designed
for optimal braking effect at all speeds and
temperatures.
Certain speeds, braking forces and ambient
conditions (e.g. temperature and humidity) can
therefore cause the brakes to “squeal”.
Unsuitable or incorrectly installed floor mats or
objects can obstruct the movement of the brake
pedal or prevent application of the brake pedal.
f Do not obstruct the pedal travel with floor mats
or other objects.
In heavy rain, while driving through water or after
leaving a car wash, the braking action may be
delayed and increased pressure may be required.
f For this reason, keep further back from the
vehicle in front and “dry” the brakes by
applying them at intervals. Make sure that the
traffic behind you is not affected.
After a long drive over salted or gritted roads,
a coating may form on the brake disks and pads
that significantly reduces friction and therefore
also braking effect.
f Even though the brake disks consist of alloyed
gray cast iron, they will unavoidably start to
corrode if your vehicle is parked for an
extended period. The brakes will tend to “rub”
as a result.
The nature, extent and effects of corrosion
depend on the amount of time the vehicle was
parked, whether road salt or grit was spread
and whether grease-dissolving agents were
used in car washes (not on vehicles with
Porsche Ceramic Composite Brake).
To prevent corrosion of the brake disks,
“brake them dry” before parking the vehicle
(not on vehicles with Porsche Ceramic
Composite Brake).
If braking comfort is noticeably impaired, we
recommend that you have the brake system
checked by experts at an authorized Porsche
dealer.
f To relieve the brake system on downhill
stretches, change down to a lower gear in
good time (engine braking).
If engine braking is insufficient on steep
stretches, operate the footbrake at intervals.
Avoid continuous braking as it overheats the
brakes and reduces the braking effect.
For information on brake fluid and checking the
brake fluid level:
f Please see the chapter “BRAKE FLUID” on
page 245.
New brake pads or linings
New brake pads have to be “broken in”, and
therefore only attain optimal friction when the car
has covered several hundred miles or km.
The slightly reduced braking ability must be
compensated for by pressing the brake pedal
harder. This applies whenever the brake pads
and/or brake disks are replaced.

(30–160 km/h) when driving on open roads
without you having to use the accelerator.
If a vehicle traveling ahead of you in the same lane
is detected as driving slower than the selected
speed, adaptive cruise control will automatically
maintain a set distance from the vehicle in front.
Adaptive cruise control slows your vehicle down if
the distance to the vehicle ahead becomes too
short and accelerates your vehicle if the distance
increases.
If the current traffic situation does not allow you to
drive safely at a constant speed and with sufficient
distance to the vehicle in front, using the adaptive
cruise control can cause accidents.
f Do not use the adaptive cruise control in heavy
traffic, in city traffic, on twisting roads or under
unfavorable road conditions (e.g. wintry or wet
conditions, varying road surfaces).
f Observe all local and national speed limits.
Adaptive cruise control will not detect stationary
or slowly moving vehicles, pedestrians, objects on
the road, oncoming vehicles in the same lane or
cross traffic.
f You must pay attention to your vehicle’s
position in relation to other objects and
intervene as needed to ensure safe driving.
f Always keep the direction of travel in your field
of view.
Radar sensor
Adaptive cruise control uses a radar sensor
located in the middle of the front apron (arrow).
Information
f Always keep the radar sensor clean and free of
ice and snow to ensure that it is fully functional.
For car care instructions:
f Please see the chapter “CAR CARE
INSTRUCTIONS” on page 255.
This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled

Operating principle of adaptive cruise
control
No vehicle detected in front – open road
driving
Adaptive cruise control operates like a cruise
control system. The desired speed that was set is
maintained constantly.
Vehicle detected in front – driving in traffic
If a vehicle traveling ahead of you in the same lane
is detected as driving slower than the selected
desired speed, adaptive cruise control will
automatically maintain a set distance from the
vehicle in front.
If the vehicle in front stops, adaptive cruise control
will slow your vehicle down to a stop provided this
is possible within the control limits of the system.
Adaptive cruise control actively keeps your vehicle
at a standstill.
If the vehicle in front drives off, automatic speed
control and distance control can be resumed.
Speed exceeded
The speed of the vehicle can be increased at any
time by pressing the accelerator.
If the vehicle is traveling faster than the speed set
by adaptive cruise control (ACC), adaptive cruise
control is deactivated.
The message “ACC passive” will appear on the
multi-purpose display of the instrument panel.
The desired speed that was stored is retained.
After the accelerator pedal is released, the ACC
adapts the vehicle speed to the desired speed and
adjusts the distance in following mode.
For information on the “ACC passive” status:
f Please see the chapter “OPERATING STATES
WHEN ADAPTIVE CRUISE CONTROL IS
SWITCHED ON” on page 163.

If the vehicle in front stops, your vehicle will slow
down and come to a stop within the control limits
of the system if adaptive cruise control is active.
The indicator light lights up on the
instrument panel.
The vehicle is actively held at a stop.
For information on the HOLD function:
f Please see the chapter “HOLD FUNCTION:
DRIVE-OFF ASSISTANT, STANDSTILL
MANAGEMENT” on page 192.
Information
– Depending on the traffic flow, e.g. slow
moving traffic, stopping is initiated by a slow
crawling phase, which brings the vehicle to
a standstill.
– When adaptive cruise control is operating
normally or when the HOLD function is active,
the brake pedal may feel different and you may
hear hydraulic noises.
This behavior is normal for the system.
It is not a fault.

– If the ignition is switched off.
– When PSM is off.
– If the driver’s door is opened and the driver’s
safety belt is not fastened.
– When parking or maneuvering in very tight
spaces.
– When the electric parking brake is activated.
– When the Tiptronic selector lever is in position
N, R or P.
– On upward or downward gradients of more
than 20 %.
– When Porsche Hill Control (PHC) is active
(or on standby).
If one of these exception situations occurs when
adaptive cruise control is switched on, adaptive
cruise control will be switched off.
A message to this effect will appear on the
multi-purpose display.
Driving and Driving Safety 167
Warning messages
Overtake request when adaptive cruise
control is active (ACC active)
If adaptive cruise control detects that braking
assistance is required on the part of the driver,
a warning signal sounds and the warning message
“Distance! Please brake!” appears on the multi-
purpose display.
Traffic situations in which vehicles
cannot be reliably detected
The radar sensor for adaptive cruise control scans
a narrow, cone-shaped area in front of your
vehicle.
Detection can be limited or unreliable, depending
on the traffic situation and the size of the vehicle
in front. The system may brake too late or
unexpectedly. Stationary vehicles are not
detected. The system cannot respond to
stationary vehicles.
f Drive with extreme care.
f Slow down if necessary.
A – Vehicles changing lanes/cutting in
If a vehicle is changing lanes or cutting in ahead
of you in the same lane, the vehicle will only be
detected when it has moved completely into
your lane.
B – Vehicles with a small cross-section/
narrow vehicles
Narrow or small vehicles will not be detected or
will be detected too late.
168 Driving and Driving Safety
C – Driving into and out of corners
When driving into and out of corners, vehicles will
not be detected or will be detected too early,
or adaptive cruise control will react to vehicles in
adjacent lanes.
D – Stationary vehicles
A stationary vehicle that appears suddenly in the
detection field of the radar sensor, e.g. after
a vehicle in front changes lanes, will not be
detected by adaptive cruise control.
Active Safety – Porsche “Active Safe”
The adaptive cruise control sensor is used for
the Porsche “Active Safe” functions.
These include:
– Brake system prefilling
Prefilling of the brake system if the radar
sensor detects that the vehicle is coming
critically close to a moving obstacle in order
to bridge the air gaps and improve braking
response.
– Brake Assist Plus
Reduction of the activation threshold of the
Brake Assist function if the sensor detects that
the vehicle is coming critically close to
a moving obstacle.
The activation threshold of the Brake Assist
function is reduced in three stages, depending
on how critical the danger situation is.
Information
– All Porsche “Active Safe” functions are active
for speeds of more than 20 mph (30 km/h).
Latent warning (visual)
If the vehicle is driving too close to the vehicle in
front for a long time, to avoid a collision if the
vehicle in front brakes, a latent warning appears
on the multi-purpose display to warn the driver.
f Stay further back from the vehicle in front if
necessary.
Driving and Driving Safety 169
Prewarning (acoustic and visual)
If the radar sensor detects that the vehicle is
coming critically close to and is very likely to
collide with an obstacle moving in front, an
acoustic and visual prewarning is issued.
This warns the driver and still allows a collision to
be prevented if the driver reacts accordingly.
Acute warning (acoustic, visual and tangible)
If the driver does not react to the prewarning by
braking, this is quickly followed by an acute
warning, which involves a braking jolt as well as
the acoustic and visual warning.
A braking jolt is felt in the vehicle as a result
of a very quick build-up of brake pressure.
This alerts the driver to the traffic situation.
The driver can still prevent a collision by reacting
accordingly in this dangerous situation.
Information
The situations described below lead to the
assumption that the driver is driving carefully and
the prewarning and acute warning functions are
disabled:
– The driver drives around tight corners.
– The driver is braking.
– If the driver accelerates sharply, this action
is interpreted as an active driving request
(e.g. indicating the driver’s intention to
overtake).
– When adaptive cruise control is on, the
Porsche “Active Safe” warnings are inactive.
There is no need for these warnings because
adaptive cruise control decelerates in good
time and the visual and acoustic overtake
request “Distance! Please brake!” is issued
early as required.
Switching Porsche “Active Safe”
warnings on/off
The latent warning and prewarning functions are
switched off by default. The acute warning
function is active.
Latent warnings and prewarnings can be activated
under “Prewarning on” on the multi-purpose
display.
The settings remain stored when the ignition is
switched on and off.
f Please see the chapter “ACTIVE SAFE (PAS)”
on page 131.
170 Driving and Driving Safety
Lane Change Assist (LCA)
Lane Change Assist (LCA) uses radar sensors to
help the driver to monitor the blind-spot area and
the traffic situation behind the vehicle.
Warning indicators are integrated in both door
mirrors. The warning indicator B on the left door
mirror assists the driver in changing into the left
lane, while the warning indicator on the right door
mirror assists the driver in changing into the right
lane.
The warning indicator lights up to indicate that
the Lane Change Assist system on this side has
detected a vehicle and considers this critical for
changing lanes. This form of display is called the
information stage. The information stage is
designed so that you notice it merely by glancing
at the door mirror.
When you set the turn signal and Lane Change
Assist has detected a vehicle that it regards as
critical, the warning indicator on the door mirror
will flash brightly several times. This form of
display is called the warning stage.
This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled

Information
The system helps when driving on highways and
on country roads. For this reason, it works at
a driving speed of between 20 and 156 mph
(30 and 250 km/h).
Even when using the Lane Change Assist, the
driver is still responsible for taking due care when
changing lanes and assessing the traffic situation.
f Please bear in mind that the sensors will not
detect all vehicles in every situation.
f Please note that Lane Change Assist cannot
alert you in good time to vehicles approaching
at high speed from behind or vehicles that are
falling back.
f Radar sensor vision can be impaired by rain,
snow or heavy spray. As a result, vehicles will
not be detected adequately or vehicles will not
be detected at all in some cases by Lane
Change Assist. Keep the direction of travel and
the relevant area around the vehicle in view at
all times.
f Please note that Lane Change Assist will only
alert you to approaching vehicles or vehicles in
the blind-spot area when you are driving at
20 mph (30 km/h) or faster.
f Please note that Lane Change Assist will not
work in tight corners (corner radius of less
than 109 yd. (100 m)).
f Even with Lane Change Assist, absolute care
and attention on the part of the driver is still
required while driving. Ultimately, the driver is
still responsible for changing lanes. Keep the
direction of travel and the relevant area around
the vehicle in view at all times.
Information
f To ensure that Lane Change Assist can work
properly:
Do not block the radar sensor area on the rear
bumper (see illustration) with objects
(e.g. stickers, bicycle carriers).
Also remove any snow and ice from this area.
f Do not cover the warning indicator on the door
mirror with stickers or other objects.

WARNING
h
172 Driving and Driving Safety
If the side windows in the driver’s or passenger’s
door are darkened with tinted film, the driver may
not be able to see the warning indicator on the
door mirror properly.
Detection area
The detection area of the radar sensors includes:
– the approach zone approx. 77 yd. (70 m) to
the rear and
– the blind-spot area.
The radar sensors cover the adjacent lane to the
left and right. Other lanes are not covered by the
radar sensors.
Information
Lane Change Assist does not measure the lane
width, but the system assumes that the lane has
a fixed width. The sensors cover this lane width at
the left and right.
When driving on narrow roads or when driving
off-center in a lane, it is possible that Lane Change
Assist will detect vehicles that are not in the very
next lane.
Operating principle
Lane Change Assist measures the distance and
speed difference of the detected vehicles
compared to your vehicle. Whenever Lane Change
Assist regards the speed difference and distance
as critical for changing lanes, this is indicated on
the relevant door mirror.
The warning indicator can light up when you are
overtaken by a vehicle or when you overtake
another vehicle.
When you overtake another vehicle slowly (speed
difference of less than 9 mph (15 km/h)), the
warning indicator lights up as soon as this vehicle
is in your blind-spot area and is detected by Lane
Change Assist. If there is a greater speed
difference, this is not indicated on the door mirror.
Information and Warning stage
Lane Change Assist has 2 warning indicator
stages:
– the information stage and
– the warning stage.
Depending on whether or not you have set the turn
signal to indicate that you intend to change lane,
Lane Change Assist helps you by activating the
relevant warning indicator stage.
Information stage
If you have not set the turn signal, Lane Change
Assist will inform you about detected vehicles that
will be regarded as critical for a possible lane
change. Whenever Lane Change Assist regards
the speed difference and distance of a detected
vehicle as critical, a weak light appears in the
warning indicator on the relevant door mirror.
The brightness of the information stage is
deliberately weak so as not to distract you while
driving without intending to change lanes and
looking at the road. The information stage is
clearly visible when you look in the door mirror.
Warning stage
When you set the turn signal and Lane Change
Assist has detected a vehicle on this side which it
regards as critical for changing lanes, the warning
indicator on the mirror on this side will start to
flash brightly. When the warning stage flashes
brightly several times, this should be an indication
for you to check the driving situation again by
looking in the door mirror and looking over your
shoulder.
Information
The brightness of the warning indicator on the
door mirror can be changed.
f Please see the chapter “SETTING DISPLAY
BRIGHTNESS ON DOOR MIRROR” on
page 175.
Driving and Driving Safety 173
Driving situation – vehicle approaching
fast
A – Warning indicator on door mirror does
not light up
The sensors do not detect a vehicle. No lights on
warning indicator on door mirror.
B – Warning indicator lights up in information
stage
The sensors detect a fast approaching vehicle –
on the left lane in the example. This vehicle is
already regarded as critical for changing lanes
due to the significant speed difference even
though it is still a good distance away.
The warning indicator on the door mirror lights
up in information stage.
C – Warning indicator flashes in warning
stage
When you set the turn signal in driving situation B,
the warning indicator on the door mirror will flash
brightly several times. Lane Change Assist is
telling you that you may have overlooked
a vehicle.
Information
– The faster a vehicle is approaching, the earlier
the warning indicator on the door mirror lights
up. You are alerted to all vehicles detected by
Lane Change Assist when they are in the
“blind-spot area” at the latest.
– Changing lanes can already be critical for
vehicles approaching at speed if there is still
no indication on the door mirror.
Driving situation – vehicle approaching
slowly
A – Warning indicator on door mirror does
not light up
The sensors detect a slowly approaching vehicle –
on the left lane in the example. Given the small
speed difference and the long distance, this is not
indicated on the door mirror.
B – Warning indicator lights up in information
stage
The slowly approaching vehicle is now closer.
The warning indicator on the door mirror lights up

Information
– The faster a vehicle is approaching, the earlier
the warning indicator on the door mirror lights
up. You are alerted to all vehicles detected by
Lane Change Assist when they are in the
“blind-spot area” at the latest.
– Changing lanes can already be critical for
vehicles approaching at speed if there is still
no indication on the door mirror.
Driving situation – vehicles falling back
slowly
A – Warning indicator on door mirror does
not light up
Lane Change Assist has not yet detected the
vehicle you have overtaken. No lights on warning

fast
A – Warning indicator on door mirror does
not light up
Lane Change Assist has not yet detected the
vehicle you have overtaken. No lights on warning
indicator on door mirror.
B – Warning indicator on door mirror does
not light up
Lane Change Assist detects the vehicle that is
falling back fast (speed difference of more than
9 mph (15 km/h)) on the passenger’s side, but
does not regard it as critical for changing lanes
because it is falling back fast. No lights on warning
indicator on door mirror.

there is still no indication on the door mirror.
Driving and Driving Safety 175
Setting display brightness on door mirror
The brightness of the warning indicator for both
the information stage and warning stage is
automatically adjusted according to the ambient
brightness.
You can also adjust the basic brightness as
required on the multi-purpose display.
f Please see the chapter “LANE CHANGE
ASSIST (LCA)” on page 131.
The new brightness is displayed briefly during the
setting process. This is the level of brightness
displayed for the information stage. The
brightness of the warning stage depends on the
brightness of the information stage.
f Set the brightness of the information stage so
that you can clearly see the warning indicator
lighting up when you look in the door mirror,
but cannot see it when you look straight ahead
through the windshield.
In very dark or bright surroundings, the warning
indicator may already be at the lowest or highest
level of automatic brightness adjustment. In such
cases, there may not be any noticeable change in
the brightness of the warning indicator on the door
mirror when you adjust the basic brightness.
When you change the basic brightness in very
bright or dark surroundings, you may not notice
any change until you are back in an area with
moderate ambient brightness.
Information
– Lane Change Assist is not active while you are
adjusting the brightness. The warning indicator
lights up briefly only to help you to set the
brightness.
– Your settings are automatically stored and
assigned to the radio key you are using.
General information
System-related limits are set for Lane Change
Assist while driving. Please drive with extreme
care therefore:
– when driving around corners
– when driving in lanes that are not of standard
width.
When driving around corners
– Lane Change Assist cannot detect vehicles in
tight corners (corner radius of less than
109 yd. (100 m)).
– When driving around a corner, Lane Change
Assist may react to a vehicle driving two lanes
over from you and the warning indicator on the
door mirror may light up.
Lane width
– The Lane Change Assist detection area is
designed in such a way that it covers the two
adjacent lanes (left and right) on lanes of
standard width regardless of whether you are
driving exactly in the middle or more on the
edge of your lane.
– When you are driving on narrow lanes, this area
may cover even more lanes, particularly if you
are driving at the edge of your lane.
In situations like this, vehicles driving two lanes
over from you can also be detected and Lane
Change Assist could switch to the information
or warning stage.
– Likewise, when driving on very wide lanes,
vehicles in the next lane may not be detected
because they are outside of the detection
area.
176 Driving and Driving Safety
For information on warning messages on the
multi-purpose display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 139.
Information
– The Lane Change Assist function can be
restricted in tight corners, on undulating roads
and in adverse weather conditions.
– The radar sensors can sometimes detect
other objects (e.g. high or raised crash
barriers), not just vehicles.
– Lane Change Assist does not measure the lane
width, but the system assumes that the lane
has a fixed width. The sensors cover this lane
width at the left and right. When driving on
narrow roads or when driving off-center in
a lane, it is possible that Lane Change Assist
will detect vehicles that are not in the directly
adjacent lane and signal these as critical.
f If the positions of the radar sensors were
changed following a rear-impact collision,
for example, always have the Lane Change
Assist system checked out at a specialist
workshop for safety reasons.
Car Audio Operation/Tips
For radio operation see your radio manual
which is included with your on-board
literature.
FM reception
A vehicle is not an ideal place to listen to a radio.
Because the vehicle moves, reception conditions
are constantly changing.
Buildings, terrain, signal distance and noise from
other vehicles are all working against good
reception.
Some conditions affecting FM may appear to be
problems when they are not.
The following characteristics are completely
normal for a given reception area, and they do not
indicate any problem with the radio itself.
Information
Electronic accessories should only be installed by
your authorized Porsche dealer.
Equipment which has not been tested and
approved by Porsche may impair radio reception.
Fading and drifting
FM range is limited to about 25 miles (40 km),
except for some high power stations.
If a vehicle is moving away from the desired
station's transmitter, the signal will tend to fade
and/or drift. This condition is more prevalent with
FM than AM, and is often accompanied by
distortion.
Fading and drifting can be minimized to a certain
degree by careful attention to fine tuning or
selection of a stronger signal.
Static and fluttering
When the line-of-sight link between a transmitter
and vehicle is blocked by large buildings or
mountains, the radio sound may be accompanied
with static or fluttering because of the
characteristic of FM.
In a similar effect, a fluttering noise is sometimes
heard when driving along a tree-lined road.
This static and fluttering can be reduced by
adjusting the tone control for greater bass
response until the disturbance has passed.
Multipath
Because of the reflecting characteristics of FM,
direct and reflected signals may reach the antenna
at the same time (multipath) and cancel each other
out.
As a vehicle moves through these electronic dead
spots, the listener may hear a momentary flutter
or loss of reception.
Station swapping
When two FM stations are close to each other, and
an electronic dead spot, such as static or
multipath area, interrupts the original signal,
some-times the stronger second signal will be
selected automatically until the original one
returns.
This swapping can also occur as you drive away
from the selected station and approach another
station of a stronger signal.
Driving and Driving Safety 177
Compact disk player
To avoid damage to compact disk player and
disks.
f Use only compact disks labeled as shown,
having no dirt, damage or warpage.
f Never attempt to disassemble or oil any part
of the player unit. Do not insert any object
other than a disk into the slot. Remember there
are no user-serviceable parts inside the
compact disk player.
f Do not allow the disk to sustain any
fingerprints, scrapes or stickers on the
surfaces. This may cause poor sound quality.
Hold the disk only on the edge or center hole.
f When not in use, take the disk out of the player,
put the disk back into its case and store it
away from dust, heat, damp and direct
sunlight.
Leaving the disk on the dashboard in the sun
can damage the disk.
f If the disk gets dirty, clean the disk by wiping
the surfaces from the center to the outside in
a radial direction with a soft cloth.
Do not use a conventional record cleaner or
anti-static record preservative.
Disk cleaners are available in audio stores.
Car Telephone and Aftermarket Alarms
Important legal and safety information
regarding the use of cellular telephones
Some states may prohibit the use of cellular
telephones while driving a vehicle. Check the laws
and regulations on the use of cellular telephones
in the areas where you drive.
Looking away from the road or turning your
attention away from your driving to operate a cell
phone will sooner or later cause an accident.
f Do not attempt to operate a hand-held cell
phone while you are driving. Safety is more
important than a phone call.
f Learn to operate the hands-free phone, if it is
available, before you start driving. Then make
use of the hands-free phone at all times.
It is essential to observe the telephone
manufacturer’s instructions before operating
the telephone.
Any portable telephone or radio transmitter which
is used in a Porsche must be properly installed in
accordance with the technical requirements of
Porsche.
The transmission power must not exceed
10 W.
The devices must possess a type approval for
your vehicle and have an “e” symbol.
If you should require equipment with transmission
power values greater than 10 W, please consult
your authorized Porsche dealer for this purpose.
They are familiar with the technical requirements
for installing devices of this kind.
The antennas for all radios and telephones with a
transmitting antenna must be externally mounted.
The improper installation of radios or telephones
or use of a radio or telephone with a transmitting
antenna inside the car may cause the warning
lights to come on.
Improper installation of such equipment can
create a discharged battery or excessive current
draw from added equipment.
If aftermarket systems are installed by non-
dealership technicians or outside the selling
dealer, problems may result. Installation of
aftermarket equipment is not covered under the
New Car Warranty.
f Consult your authorized Porsche dealer about
the installation of non-Porsche approved
equipment.
Reception quality
The reception quality of your car telephone will
change constantly when you are driving.
Interference caused by buildings, landscape and
weather is unavoidable. It may become particu-
larly difficult to hear when using the hands-free
function due to external noise such as engine and
wind noise.
Automatic car-wash
f Unscrew external antennas before using an
automatic car-wash.

Porsche Communication
Management (PCM)
Setting or operating the on-board computer,
radio, navigation system, telephone or other
equipment when driving could distract you from
the traffic. You could lose control of the vehicle.
f Operate the components while driving only if
the traffic situation allows you to do so safely.
f Carry out any complicated operating or setting
procedures only with the vehicle stationary.
f If it is necessary to operate these components
while the vehicle is in motion, use the function
keys on the multi-functional steering wheel.
f Refer to the separate operating instructions
before putting the PCM into operation.
When put into operation for the first time, a
distance of approx. 3 miles (5 km) must be driven
in order for the navigation system to complete the
process of fine calibration. The same applies
when the tires are changed (e.g. summer/winter
tires) or new tires fitted. Full location accuracy is
not yet achieved during the fine-calibration
process.
If the vehicle has been transported (e.g. ferry, car
train), the system may take a few minutes after
being switched on before it determines the current
location.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation
system is operational once more.

180 Driving and Driving Safety
Tiptronic S
Porsche Tiptronic S is an 8-speed automatic
transmission and features an “automatic” and
a “manual” gearshift mode.
In automatic selection mode (selector-lever
position D), gear changing is automatic.
You can change temporarily from automatic to
manual mode using the rocker switches on the
steering wheel, depending on the driving program.
In manual selection mode (selector-lever
position M), you change gear using the shift
buttons on the steering wheel or by pushing the
selector lever forward or back.
The functions of selector-lever positions D and M
are different in the on-road driving program and
the off-road driving program.
You can change between selector-lever positions
D and M as you wish while driving.
The currently engaged gear is retained when you
change from D to M.
If you change from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is engaged.
Information
Make sure not to actuate the shift buttons on the
steering wheel inadvertently, thereby triggering
undesired gear changes.
Changing selector-lever position
The selector lever is blocked when the ignition is
switched off.
The selector lever can be moved from position P
and N only with:
– the ignition switched on,
– the brake pedal pressed and
– the release button pressed (arrow).
Release button
The release button (arrow) on the front of the
selector lever prevents unintentional gear
changes.
The release button must be pressed when shifting
to position R or P.
The selector lever can no longer be operated in
the event of an electrical fault.
f For information on emergency release of the
blocked selector lever:

Selector-lever position
Display for selector-lever position and
engaged gear
When the engine is running, the display shows the
selector-lever position and engaged gear.
Selector-Lever Positions
P – Parking lock
When the selector lever is in position P, the drive
wheels are mechanically locked.
f Engage parking lock only when the vehicle is
stationary.
f Engage parking lock after applying the
electric parking brake and release it before
releasing the electric parking brake.
f Always apply the electric parking brake before
leaving the vehicle.
The ignition key can be removed only in selector-
lever position P.
R – Reverse gear
f Select reverse only if the vehicle is stationary
and the brake is applied.
N – Neutral
Selector-lever position N must be selected for
towing or in car washes, for example.
f Select the desired position for moving off
(D, M or R) only when the engine is idling and
when pressing the brake pedal.
D – Automatic selection mode
(D – Normal mode)
f Select selector-lever position D for “normal”
driving.
The gears are shifted automatically according
to the accelerator position and speed.
Depending on how the vehicle is driven
(economical or sporty driving style) and on the
resistance (e.g. driving uphill), the gear-changing
points are shifted towards higher or lower engine-
speed ranges. The accelerator movement, driving
speed, longitudinal and lateral acceleration and
the road profile all have an influence on the gear-
changing characteristic.
f Unwanted upshifts, e.g. when entering
corners, are prevented by swiftly releasing the
accelerator pedal.
Depending on lateral acceleration, upshifts on
corners are not made until the engine-speed limit
is reached.
When you brake, and depending on the amount
of deceleration, the transmission changes down
earlier. For subsequent cornering, the right gear is
engaged when pressure is applied to the brakes
before the corner.
The corner is taken in a suitable gear. It is not
necessary to change down when accelerating out
of the corner.
D – Sport mode
The transmission switches to a sporty gear-
changing map. A sporty driving style is recognized
more quickly and the gear-changing speeds are
adapted to driving performance.
Braking downshifts are initiated earlier. Downshifts
occur for small decelerations, even at higher revs.
182 Driving and Driving Safety
D – Off-road mode
The transmission switches to an off-road gear-
changing map.
The gear-changing points are chosen to achieve
the best possible vehicle control on difficult
terrain.
On steep downhill stretches, upshifts are
prevented until average engine speeds are
reached.
When the vehicle is overrunning, upshifts are
prevented until the engine-speed limit is reached.
Shifting gears on the steering wheel
With the shift buttons on the steering wheel, you
can change temporarily from automatic selection
mode D to manual mode M.
Changing gear using the steering wheel could be
useful in the following situations:
– Shifting down before corners and on entering
built-up areas.
– Shifting down on downward slopes (engine
braking).
– Shifting down for brief spurts of acceleration.
The manual selection mode remains engaged:
– For cornering (depending on the lateral
acceleration) and overrunning.
– When the vehicle is stationary
(e.g. at a junction).
The system leaves manual selection mode:
– automatically after around 8 seconds
(unless cornering or overrunning),
– after driving off.
Kickdown
The kickdown function is active in selector-lever
position D and M.
f For optimum acceleration, e.g. when
overtaking, press the accelerator pedal
beyond the full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed.
Upshifts occur at the highest possible engine
speeds.
Information
Unlike in Normal and Sport mode, an automatic
upshift is not performed in manual selection
mode M in Off-road mode when the engine-speed
limit is reached.
M – Manual selection mode
The currently engaged gear is retained when you
change from D to M.
If you change from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is engaged.
The selector lever and the two shift buttons in the
upper steering-wheel spokes let you select the
eight forward gears comfortably and reliably.
Driving and Driving Safety 183
Shifting up +
f Press the selector lever or shift button on the
steering wheel forward.
Shifting down -
f Pull the selector lever or shift button on the
steering wheel back.
You can shift up or down at any time depending
on driving speed and engine speed.
Gear changes that would exceed the upper and
lower engine-speed limit are not performed.
The gear is changed down automatically just
before idle speed is reached.
f Select an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
Driving off
1st or 2nd gear can be selected for driving off.
To shift up automatically at the upper
engine-speed limit:
f Press the accelerator pedal beyond the full-
throttle point (kickdown).
Information Normal and Sport mode
There is no automatic upshift at the upper
engine-speed limit in selector-lever position M.
Upshift suppression can be canceled in Normal
and Sport mode by kickdown operation.
The transmission shifts down to the lowest
possible gear depending on the driving speed
and engine speed.
If, for example, the engine-speed limit is reached
during overtaking and an automatic upshift does
not occur, the transmission shifts up in this case
as a result of kickdown operation.
Information Off-road mode
The kickdown function is not available in selector-
lever position M in Off-road mode.
If, for example, the upper engine-speed limit is
reached during overtaking and an automatic
upshift does not occur, the transmission only
shifts up when you press a shift button (+) or
briefly press the selector lever (+).
Manual selection mode failure
If manual mode fails, the control electronics
system switches to automatic mode.
In this case, selector-lever position D will be
displayed on the instrument panel.
f Have the fault corrected at an authorized
Porsche dealer.
Stopping
f For a brief stop (e.g. at a traffic light), leave
the selector lever in drive position and hold the
vehicle with the brake pedal.
f Do not hold the car on a slope using the
accelerator. Use the brake pedal or the
electric parking brake instead.
f Before leaving the vehicle, always apply the
electric parking brake and move the selector
lever to position P.
Information
In selector-lever positions D and M, the HOLD
function makes it easier to drive off from
a standstill on an upward slope when the engine is
running without having to press the brake.
f For information on using the HOLD function:
Please see the chapter “HOLD FUNCTION:
DRIVE-OFF ASSISTANT, STANDSTILL

The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome.
These systems cannot reduce the risk of
accidents due to inappropriate speed.
f Adapt your driving style, maneuvers and speed
to the road and weather conditions, as well as
the traffic situation.
Porsche Traction Management (PTM)
Porsche Traction Management (PTM) ensures the
best possible power distribution to the four driven
wheels on the front and rear axles. The system
always controls power distribution in such a way
that optimal propulsion is achieved, even on an
unfavorable road surface.
PTM is active at all times and, unlike PSM,
cannot be switched off.
Advantages of PTM
– Clearly perceptible improvement in traction,
driving stability and steering ability of the
vehicle.
– Better control of the vehicle when driven at its
performance limits.
– Improved straight-ahead tracking and stability.
– The above features allow for a sportier chassis
setup.
– Optimal drive torque distribution on all four
wheels, depending on the driving program.
Porsche Torque Vectoring Plus (PTV Plus)
PTV Plus is a control system for lateral dynamic
braking intervention for sportier and more agile
cornering and features an electronically controlled
rear differential lock.
PTV Plus improves steering behavior and steering
precision with gentle braking interventions - which
are not even noticed by the driver - on the inside
rear wheel when cornering. The vehicle follows the
steering angle of the front wheels more precisely.
Understeering at the stability limit is almost fully
prevented. This in turn enhances the lateral-
acceleration potential. Higher cornering speeds
are then possible.
The electronically controlled rear differential lock
continuously checks the driving situation of the
vehicle and distributes the drive torque to the rear
axle as required. This has the following
advantages:
– Improved traction
– Reduced load change responses when
cornering at speed
– Improved driving stability at higher speeds
– Off-road traction is also significantly improved
due to the possibility of locking the rear
axle fully.
Please see the chapter “DRIVING PROGRAMS
FOR ON-ROAD AND OFF-ROAD DRIVING” on
page 184.
Porsche Stability Management (PSM)
PSM is an active control system for stabilization of
the vehicle during extreme driving maneuvers.
Advantages of PSM
– Best possible traction and lane-holding ability
in all driving situations – even on road surfaces
with varying friction.
– The system compensates for undesired
vehicle reactions (load-alteration effect) when
the driver releases the accelerator pedal or
brakes on corners. This compensation
functions up to the maximum lateral
acceleration.
– PSM actively stabilizes the vehicle as required
during dynamic driving maneuvers (e.g. rapid
steering movements, during lane changes or
on alternating corners).
– Improved braking stability on corners and on
different or varying road surfaces.
– Improved brake function and shorter stopping
distance in the event of emergency braking.
Operational readiness
PSM is switched on automatically every time you
start the engine.
Driver Responsibility
WARNING
h
190 Driving and Driving Safety
Function
PSM intervenes and corrects the course if the
actual direction of motion deviates from the
desired course (steering-wheel position):
It brakes individual wheels as needed.
If necessary, PSM also influences the engine
power or the gear-changing characteristic of
Tiptronic in order to stabilize the vehicle.
The events below inform the driver of PSM control
operations and warn him to adapt his driving style
to the road conditions:
– The PSM warning light on the instrument panel
flashes.
– Hydraulic noises can be heard.
– The vehicle decelerates and steering-wheel
forces are altered as PSM controls the brakes.
– Reduced engine power.
– The brake pedal pulsates and its position is
changed during braking.
In order to achieve full vehicle deceleration,
foot pressure must be increased after the
brake pedal has begun vibrating.
Examples of PSM control operations
– If the “front wheels of the vehicle drift” on
a corner, the engine power is reduced and the
rear wheel on the inside of the corner is braked
if necessary.
– If the rear of the vehicle swings out on
a corner, the front wheel on the outside of the
corner is braked.
– Brake system prefilling:
The brake system is prepared for possible
subsequent emergency braking if the
accelerator pedal is released suddenly and
quickly. The brake system is prefilled and the
brake pads are already applied gently to the
brake disks.
– Brake booster:
In the event of an emergency braking operation
where the pedal force is insufficient, a brake
booster provides the braking pressure
necessary for maximum deceleration at all
4 wheels.
Information
When PSM is switched off, wheel-specific brake
interventions and the anti-slip regulation system
(ASR) are also inactive.
The automatic brake differential (ABD) remains on.
Off-road PSM
(PSM in the off-road driving program)
When the off-road driving program is active, an off-
road PSM specially matched to off-road driving is
activated to improve traction.
In order to improve driveability on difficult terrain,
the response of the off-road PSM is less sensitive
in the low speed range when the vehicle is set to
the off-road driving program.
If the brakes are highly stressed, the automatic
brake differential (ABD) switches itself off to
protect the brakes. It remains deactivated until the
brake system has cooled sufficiently again.
Automatic brake differential (ABD)
The ABD system controls the front and rear axles
separately. If one wheel of an axle starts to spin,
it is braked so that the other wheel on the same
axle can be driven.
ABD recognizes different driving states, and it
features control strategies adapted to these
states. In situations in which little propulsive power
is required, such as when the vehicle moves off on
a level gravel surface, traction control already
becomes active at low engine speeds. If a large
amount of propulsive power is required, such as
when moving off on an uphill slope or for rapid
acceleration, the ABD system is adapted
accordingly.
Anti-slip regulation (ASR)
The anti-slip regulation system prevents the
wheels from spinning by adjusting the engine
power, thereby ensuring good lane-holding ability
and stable handling.
Engine drag torque control (MSR)
In conditions of excessive slip, the engine drag
torque control system prevents all driven wheels
from locking up when the vehicle is overrunning.
This is also the case for downshifts on a slippery
road.

192 Driving and Driving Safety
ABS brake system
(Anti-Lock Brake System)
ABS ensures:
– Full steering control
The vehicle remains steerable.
– Good driving stability
No skidding due to locked wheels.
– Optimum braking distance
Shorter stopping distance in most cases.
– Prevention of wheel locking
No flat spots on the tires.
Function
The decisive advantage of ABS lies in the driving
stability and maneuverability of the vehicle in
hazardous situations.
ABS prevents locking of the wheels during full
braking, on almost all road surfaces, until just
before the vehicle stops.
ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a “juddering noise”
warn the driver to adapt his driving speed to the
road conditions.
f If full braking is necessary, fully depress the
brake pedal during the whole braking
operation, even though the pedal is pulsating.
Do not reduce the braking pressure.
If the ABS warning lights light up on the instrument
panel and on the multi-purpose display of the
instrument panel while the engine is running,
ABS has switched off because of a fault.
In this case, the brake system will operate without
lock prevention, as in vehicles without ABS.
f Adapt your driving style to the changed
braking behavior.
The ABS must be checked immediately at your
authorized Porsche dealer in order to prevent
the occurrence of further faults with
unpredictable consequences.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with non-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off.
Off-road ABS
(ABS in the off-road driving program)
When the off-road driving program is active,
an ABS configuration specially matched to
off-road driving is activated automatically.
In the event of braking on loose ground, the
permissible slip values for ABS braking are
increased so that the off-road braking distance
is reduced (wheels dig into the surface).
If the driver needs to steer, the off-road driving
program is automatically switched off to maintain
steerability.
HOLD function: Drive-Off Assistant,
standstill management
The HOLD function, as an assistance function,
assists the driver when stopping and driving off
on upward slopes.
The vehicle is automatically prevented from rolling
back away from the desired direction of travel.
When the HOLD function is active, the indicator
light on the instrument panel comes on.
Driving off with the Drive-Off Assistant on
vehicles with manual transmission
1. Hold the vehicle securely on the slope with
the footbrake.
The engine must be running.
2. Press the clutch pedal fully.
3. Engage a gear corresponding to the
direction of travel up the slope (1st gear or
reverse gear).
4. Release the footbrake while keeping the clutch
pedal pressed.
The vehicle is held on the slope to facilitate
driving off and prevent it from rolling back.
5. Drive off as usual.
ABS warning light USA
ABS warning light Canada
Driving and Driving Safety 193
The limits set by the physics of driving cannot be
overcome, even with the HOLD function.
Responsibility for driving off on upward slopes is
still the driver’s, despite the HOLD function.
Assistance by the HOLD function is not always
guaranteed when stopping and driving off on
a slippery surface (e.g. on icy or loose surfaces).
In this case, the vehicle can slip.
f Always adjust your driving style to the driving
conditions and vehicle load. Use the footbrake
if necessary.
If the Drive-Off Assistant is not functioning, the
driver cannot be assisted when driving off on hills.
f Hold the vehicle with the footbrake.
If the vehicle comes to a standstill on a steep
uphill gradient without using the service brake,
this may result in a certain roll-back before the
vehicle is held by the HOLD function. In this
situation, the driver can reduce the roll-back by
pressing the footbrake.
f Assist holding of the vehicle by increasing the
braking force with the footbrake.
Brake pedal feels different. When adaptive cruise
control is operating normally or when the HOLD
function is active, the brake pedal may feel
different and you may hear hydraulic noises.
Pressing the footbrake while the HOLD function
is active can cause pulsations in the pedal.
This behavior is normal for the system.
It is not a fault.
Porsche Hill Control (PHC)
Porsche Hill Control is an assistance system that
helps the driver when driving slowly downhill at
speeds of between approx. 2 mph (3 km/h) and
20 mph (30 km/h), e.g. on steep slopes or on
wintry mountain roads, both when driving forward
and reversing.
The system limits the speed by braking on all four
wheels. ABS remains active to prevent the wheels
from locking.
On vehicles with manual transmission, the system
adapts the speed in such a way that the engine is
not braked at idle speed.
Like all brakes, the braking ability of Porsche
Hill Control is impaired on slippery surfaces
(e.g. on icy roads or loose surfaces).
Reduced braking ability on a slippery surface.
f Always adjust your driving style to the driving
situation.
Preconditions:
– PHC is on.
– The speed must not exceed approx. 20 mph
(30 km/h).
– The gradient must be at least approx. 12 %.
– The driver does not accelerate or brake.

h
200 Driving and Driving Safety
Recommended procedure
f Switch off the off-road driving program.
f Clean headlights and tail lights and check them
for signs of damage.
f Clean the front and rear license plates.
f Clean the tire tread with a jet of water and
remove any foreign objects.
f Clean wheels, wheel housings and the
underbody with a jet of water.
f Check whether the vehicle has picked up plant
parts or branches.
These materials increase the risk of fire and
can damage fuel lines, brake hoses, boots of
the axle joints and drive shafts.
f After off-road driving, always check the entire
floor assembly, tires, body structure, steering
system, chassis and exhaust system for signs
of damage.
f After driving for an extended period through
mud, sand, water or substances with a similar
soiling effect, check the brake disks, brake
pads, wheels and axle joints and have them
cleaned.
f If you experience severe vibrations after
driving off-road, check the wheels for foreign
substances. These substances can produce
an imbalance which might be responsible for
the vibrations. Removing these deposits may
remedy the problem.
Off-Road driving on uphill gradients
f Do not turn round when driving on uphill
gradients.
f If it is not possible to climb an uphill gradient,
the vehicle must be backed down in reverse
gear.
f Do not drive over embankments or slopes at
steep diagonal angles.
f If the vehicle starts to tilt, immediately steer in
the direction of the tilt (line of slope).
f When driving on uphill gradients, never let the
vehicle roll back when in neutral or not in gear.
Exclusive use of the footbrake is too risky in
such situations.

f Activate the off-road driving program before
taking extreme uphill or downhill gradients.
f Do not perform manual gear changes when
driving, and try to avoid stopping.
f Avoid high engine speeds.
Traction on uphill gradients
Information
f Activate the off-road driving program and
engage differential lock(s) if necessary.
f When driving uphill, go easy on the accelerator
and make sure that wheels have sufficient
traction (do not spin).
f Do not adjust the vehicle level on a slope.
f Avoid high engine speeds.
f Drive slowly.
Off-Road driving on downhill gradients
f Do not drive over embankments or slopes at
steep diagonal angle.
f Drive downhill slowly, with the front wheels
pointing straight ahead.
f If the vehicle starts to tilt, immediately steer in
the direction of the tilt (line of slope).
f When driving downhill, never let the vehicle roll
when in idle.
f Use engine braking effect.
If the engine braking effect is not sufficient to
appropriately check the speed, gently apply
the footbrake.
f Activate Porsche Hill Control (PHC).
Please see the chapter “PORSCHE HILL
CONTROL (PHC)” on page 193.
Information
f Activate the off-road driving program. Off-road
ABS is switched on automatically.
f Do not perform manual gear changes when
driving, and try to avoid stopping.
f Do not adjust the vehicle level on a slope.
The special control mechanism of the off-road
ABS permits controlled brief lock-up of the front
wheels so that they can dig into the loose surface
more effectively.
Locked wheels slip and can no longer be steered.
f When driving down steep hills on unpaved
surfaces, brake carefully to prevent sliding.

Humps
f Pay attention to the ground clearance of the
vehicle.
Information
f Activate the off-road driving program and
engage differential lock(s) if necessary.
f Just before reaching the hump, ease off the
accelerator slightly and use only the vehicle’s
momentum to cross the hump. This will
prevent the vehicle from jumping over the
hump and landing on the next downward slope
at excessive speed.
f Avoid high engine speeds.
Driving through water
f Pay attention to the ground clearance of the
vehicle.
f Before driving through water, check the water
depth, water speed and the condition of the
surface beneath it.
The water must not be deeper than 19.7 in.
(50 cm). The water must not be deeper than
21.9 in. (55.5 cm) for vehicles with level
control and height adjustment.
f Do not drive through deep or rapidly flowing
water.
Deep or rapidly flowing water, such as
mountain streams or flooded roads, can cause
the vehicle to deviate from the desired path
and roll over.
f Never open the doors when driving through
water.
Soiling can impair the braking action.
f Check and clean the brakes if they are soiled.
Danger of steering assistance failing during a long
trip in water if the drive belt slips.
f If steering assistance fails, more effort will be
required to steer.
Danger of damage to electrical systems.
f Avoid driving through salt water.
Risk of damage to the engine and accessories if
water gets into the vehicle.
f Before driving through water, check the water
depth, water speed and the condition of the
surface beneath it.
The water must not be deeper than 19.7 in.
(50 cm). The water must not be deeper than
21.9 in. (55.5 cm) for vehicles with level
control and height adjustment.
f Make sure that the door sills and rubber seals
are clean before starting to drive.
f Avoid producing bow waves by driving at an
appropriate speed.
f Do not drive through deep or rapidly flowing
water.
Deep or rapidly flowing water, such as
mountain streams, can cause the vehicle to
deviate from the desired path.
f Never open the doors when driving through
water.
Information
f Activate the off-road driving program and
engage differential lock(s) if necessary.
f Switch the air-conditioner off.
f Switch the headlights off.
f Avoid high engine speeds.
f Do not perform manual gear changes when
driving, and try to avoid stopping.
Moving off in water can be difficult due to the
high resistance and the loose surface involved.
f Raise the vehicle level before driving through
water.
f Start driving through water at a shallow place
at walking speed.
f After checking the body of water, take the
shortest path through it.
f Never drive into water with momentum.
The resulting bow wave could damage the
engine and accessories.
f Adjust your driving style to unfamiliar
surroundings.
f Drive through the water slowly and at
a constant speed.
f Never turn around when crossing a body of
water.
f If it is not possible to cross a body of water,
the vehicle must be backed out in reverse
gear.
The power-steering pump and alternator can fail if
the vehicle is driven through water for an extended
period.
f If the power-steering pump fails, substantially
more force is necessary in order to steer.

Information
The vehicle requires a particularly thorough check
after driving through water.
f Remove mud from the tire tread.
f Briefly “brake” the brake pads dry after driving
through water.
Crossing obstacles
Risk of damage to the underbody and chassis
parts.
These parts can be damaged if you do not drive
properly over obstacles.
f Always check the ground clearance of your
vehicle.
f Slowly drive over the middle of tree stumps,
boulders or other obstacles with one of the
front wheels.
f Cross the obstacle with the rear wheel in the
same way.
Information
f Activate the off-road driving program and
engage differential lock(s) if necessary.
f Get your passenger to direct you if necessary.
f Avoid high engine speeds.
f Drive slowly.
Driving on sand
Information
f Activate the off-road driving program and
engage differential lock(s) if necessary.
Loose sand is an especially tricky surface for
off-road driving.
You can often become stuck in sand within
minutes if you do not drive correctly in such
situations.
f Drive rapidly and do not stop under any
circumstances. Otherwise, the vehicle will
become bogged down.
f Follow existing tracks – provided they have not
been covered by blown sand, are not too deep
and the vehicle’s ground clearance is
sufficient.
Pay attention to the ground clearance of the
vehicle.
f If you need to stop the vehicle on sand, choose
a downward slope if possible to allow you to
drive off again more easily.
When driving on slopes with soft sand on vehicles
with Tiptronic S:
f To achieve a high engine speed, use the
manual selection mode M as well as the
off-road driving program if necessary.
If your vehicle still gets stuck:
f Do not spin the wheels. Instead, use branches,
mats or similar items to provide adequate
traction so that you can drive out of the
critical area.
Off-road driving on track ruts
Other vehicles leave ruts on many off-road tracks
or gravel roads.
f Pay attention to the ground clearance of the
vehicle.
Risk of damage to the vehicle floor.
The vehicle floor could be damaged when driving
through track ruts that are too deep.
f Always bear in mind the vehicle’s ground
clearance.
f Do not drive through ruts that are too deep.
Information
f Activate the off-road driving program and
engage differential lock(s) if necessary.
f If in doubt, drive with one wheel on the strip of
grass between the ruts.
f Avoid high engine speeds.
f Drive slowly.
