Notes on minor repairs
We recommend that you use your Porsche partner
for carrying out this work.
Experienced, Porsche trained workshop
personnel, supplied with the latest information as
well as special tools and equipment are prerequi-
sites for looking after your Porsche properly.
If, however, you work on your vehicle yourself, you
must do it with great care. Only in this way is
operational reliability fully guaranteed.
Unskilled maintenance work performed during the
guarantee period may cause you to lose your
claims.
Warning triangles
The storage location for the warning triangles is
under the left rear-seat cushion.
Warning!
Danger of injury and/or damage as a result
of braking or in the event of an accident.
f Do not place any objects between the seat
cushion and foam part.
Tool kit
The tool kit is accommodated in the spare-wheel
well under the cover of the loadspace floor.
Minor Repairs 291
First aid kit
The first aid kit is stored in the storage
compartment on the right side of the luggage
compartment.
f For information on opening the storage
compartment:
Please observe the chapter “SIDE STORAGE
COMPARTMENTS IN THE LUGGAGE
COMPARTMENT” on Page 237.
Danger!
Risk of death, injury and fire during
maintenance work.
f Do not smoke in the vicinity of the battery or
fuel system, and do not use a naked flame.
f Only work on the vehicle in the open or in well-
ventilated spaces.
f Take care when working near hot engine parts.
f Before working in the engine compartment,
always switch the engine off and let it cool
sufficiently.
f If you have to work on the engine while it is
running, always apply the parking brake and
put the gearshift lever in neutral or the
Tiptronic selector lever in position P.
f Take great care to ensure that hands, fingers,
articles of clothing (ties, sleeves, etc.),
necklaces or long hair cannot be caught up by
the radiator fans, drive belt or other moving
parts.
f Exercise extreme caution when working in the
area of the radiator fans.
The radiators and radiator fans are in the front
of the vehicle.
The fans can start running as a function of
temperature, even with the engine switched
off.
f When the ignition is on, all cables and wires of
the ignition system carry a high voltage.
Special care is therefore required.
f Always place the vehicle on stable supports if
work has to be carried out under the vehicle.
The car jack is not suitable for this.
For information on raising vehicles with air
suspension with level control and height adjust-
ment:
Please observe the chapter “RAISING VEHICLE
WITH THE JACK” on Page 205.
f Refill fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to health.
Store refill fluids out of reach of children and, if
necessary, dispose of these fluids properly.
292 Minor Repairs
Tyres and wheels
In addition to correct tyre filling pressure and
correct wheel alignment, the service life of the
tyres also depends on your driving style.
Abrupt acceleration, high cornering speeds and
heavy braking increase tyre wear. The tread wear
is also greater at higher outside temperatures and
on rough road surfaces.
Just like the engine, tyres always require the cor-
rect operating conditions. When correctly treated,
they are a long-lived safety component on your
Porsche.
For your own protection and that of other road
users, you must observe the following instruc-
tions.
We recommend inspecting the tyres for damage
after off-road driving.
Load and speed
f Do not overload your vehicle. Be careful about
the roof load. There is a danger from
overloading
+ insufficient tyre pressure
+ high speed
+ high outside temperature
(e.g. holiday driving).
Tyre pressure
The tyre pressure must match the prescribed
value.
You can find information on the tyre pressure:
– In the front left door aperture.
– In the Technical Data chapter in this Driver’s
Manual:
Please observe the chapter “TYRE
PRESSURES, COLD” on Page 367.
These values are for cold tyres (20 °C).
f Check the tyre pressure at least every
2 weeks. Always check when tyres are cold.
f On vehicles with Tyre Pressure Monitoring:
Please observe the chapter “SETTING TYRE
PRESSURE MONITORING” on Page 135.
When tyres are warm, the tyre pressure is
increased.
f Never let air out of hot tyres. This could cause
the tyre pressure to fall below the prescribed
value.
Valve caps protect the valve from dust and dirt,
and thus from leakage.
f Always screw caps down tightly.
f Replace missing caps immediately.
Insufficient tyre pressure can cause tyres to
overheat and thus be damaged – even invisibly.
Hidden tyre damage is not eliminated by subse-
quently correcting the tyre pressure.
Tyre damage
Cleaning with high-pressure cleaners can damage
the tyres.
f For further information on cleaning with high-
pressure cleaners:
Please observe the chapter “HIGH-PRESSURE
CLEANING UNITS” on Page 282.
Warning!
Risk of accident due to hidden tyre damage.
Tyres may burst, especially at high speeds.
f Check tyres including the sidewalls regularly
for foreign bodies, nicks, cuts, cracks and
bulges.
f Cross kerb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp kerbs.
f In cases of doubt, have the wheel (particularly
the inner side) checked by an expert.
Minor Repairs 293
In the case of the following tyre damage, the tyre
must be replaced for safety reasons:
– Tyre damage where the possibility of a ply
fracture cannot be ruled out.
– If the tyre has been thermally and mechanically
overloaded following a loss of pressure or
other previous damage.
Maintenance note
Tyre repairs are not permissible under any circum-
stances.
f After driving off-road, examine tyres for signs
of damage such as cuts, tears, bulges or
foreign objects stuck in the tread and replace
if necessary.
Kerbs
Heavy or sharp-angled impacts against kerbs or
sharp-edged objects (e.g. stones) can cause
hidden tyre damage that only shows up later.
Depending on the strength of the impact, the rim
flange may also be damaged.
Storing wheels
f Always store wheels in cool, dry, dark condi-
tions. Tyres without wheels should be stored in
a standing position.
f Avoid contact with petrol, oil and grease.
In no case should tyres be more than 6 years
old.
The idea that tyres become more wear-resistant
with storage and age has no foundation.
Chemical additives that make the rubber elastic
lose their effect in the course of time and the
rubber becomes brittle. The age of a tyre can be
seen from the DOT code on the tyre sidewall.
If, for example, the last four digits are 1206, this
means: the tyre was manufactured in the twelfth
week of 2006.
Tread
The less tread, the greater the danger of
aquaplaning.
f For safety reasons, replace the tyres before
the wear indicators appear (webs in the tyre
grooves, 1.6 mm high).
f Check tyre tread regularly, particularly before
and after long journeys.
Wheel balancing
f As a precaution, have wheels with summer
tyres balanced in the spring, and those with
mud and snow tyres before winter.
Only specified weights may be used for wheel
balancing.
Self-adhesive weights must not come into contact
with cleaning agents, since they could drop off.
Wheel change
f When wheels are removed, mark the direction
of rotation and position of each wheel.
Example:
FR (front right), FL, RR and RL.
f Always fit the wheels in accordance with their
marking.
294 Minor Repairs
Wheel alignment
Uneven tread wear indicates incorrect wheel align-
ment. In this case, the vehicle should be checked.
f Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
Warning!
Risk of accident. You can lose control of the
vehicle.
If, during a journey, uneven running or vibra-
tions occur that could be caused by damage
to tyres or the car:
f Reduce speed immediately, but without
braking sharply.
f Stop the vehicle and check the tyres.
If no cause for the fault can be found, drive
carefully to the nearest qualified specialist
workshop.
We recommend that you use a Porsche
partner for this work since these are staffed
with trained personnel and have the necessary
parts and tools.
Replacing tyres
f Before having new tyres fitted, find out about
the current approval status.
f Use only tyre makes tested and approved by
Porsche.
Basically, only tyres of the same make, same
type and with the same specification number
(e.g. “N0”, “N1” ...) may be fitted.
In the initial period, new tyres do not have their full
grip.
f Therefore, do not drive above moderate
speeds during the first 100 to 200 km
(60 to 120 miles).
If new tyres are fitted to only one axle, the
different tread depths on the two axles can cause
a marked change from the previous driving behav-
iour to which you have become accustomed. This
is particularly true when new tyres are fitted to the
rear axle.
The effect is reduced continuously, however, as
tyre mileage increases.
f Adapt your driving style to the changed
handling.
Tyres should only be fitted by specialist firms.
When a defective tyre is replaced, it should be
noted that deviations in tread depth must not
exceed 30 % on one axle.
f Do not use second-hand tyres if you do not
know their history.
Valves
f Use only plastic valve caps.
Rubber valves must be replaced whenever the
tyres are changed.
In the case of metal valves, please observe the
fitting and replacement instructions.
Use only genuine Porsche metal valves or valves
of the same quality, which are manufactured
according to the specifications and production
demands of Porsche.
f Protect valve inserts against soiling with valve
caps.
Soiled valve inserts can cause a gradual loss
of air.
Minor Repairs 295
Sticker for maximum speed
Winter tyres
Warning!
Risk of accident due to excessive speed.
f Always observe the permissible maximum
speed of the respective tyre.
f A sticker showing the maximum permissible
speed must be affixed in the driver’s field of
vision.
Observe the country-specific laws.
f Fit winter tyres to both axles in good time
before the cold season begins.
Your Porsche partner will be pleased to advise
you.
Maintenance note
We recommend fitting winter tyres on the vehicle
at temperatures below 7 °C since the driving
performance of summer tyres is reduced at low
temperatures. Summer tyres may be permanently
damaged at extremely low temperatures.
Winter tyres lose their suitability when their tread
depth falls below 4 mm.
f Please note that in addition to winter tyres, all-
season and all-terrain tyres also belong to the
category M+S tyres.
Wheel change
f When wheels are removed, mark the direction
of rotation and position of each wheel.
Example: FR (front right), FL, RR and RL.
f Always fit the wheels in accordance with their
marking.
Snow chains
Optimal handling characteristics can be achieved
only when snow chains are fitted on all four wheels
of the vehicle. It is also possible to fit snow chains
on only one axle (preferably the rear axle).
f Remove spacers if 18 inch tyres, snow chains
or a collapsible spare wheel are mounted.
Caution!
Risk of damage to the wheel housings if the
spacers on the rear axle are not removed
before fitting snow chains.
f The 17 mm spacers must always be removed
from the rear axle when snow chains are to be
fitted.
f For information on the spacers:
Please observe the chapter “SPACERS” on
Page 299.
For information on removing the spacers:
Please observe the chapter “CHANGING A
WHEEL WITH REMOVAL OF 17 MM SPACERS”
on Page 309.
f Use only the fine-link snow chains recom-
mended and authorised by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
296 Minor Repairs
f For information on approved snow chains:
Please observe the chapter “TYRES, RIMS,
TRACKS” on Page 365.
f Before fitting chains, remove accumulated ice
and snow from the wheel well.
f Observe the maximum permissible speed
when using snow chains of 50 km/h
(30 mph).

332 Minor Repairs
Battery
Danger!
Danger of explosion and injury and risk of
short circuit and damage to the generator
and electronic control units.
f Have the battery removed and installed only at
a specialist workshop.
The battery is located in the battery box under the
left front seat.
Warning!
Risk of short circuit and fire.
f Disconnect the battery during all work on the
electrical system.
f Ensure that tools or conductive jewellery
(rings, chains, watch straps) do not come into
contact with live parts of the vehicle.
Danger of explosion
f Do not wipe battery with a dry cloth.
f Before touching the battery, discharge any
static electricity by touching the vehicle.
Heed warnings on the battery
Read the operating instructions
Wear eye protection
Keep children away
Danger of explosion
While the battery is being charged, a
highly explosive gas mixture is formed,
so:
Fire, sparks, naked flames and
smoking are prohibited
Avoid causing sparks and short circuits
when handling cables and electrical
equipment.
In the case of batteries with central
venting, there is a greater concentration
of explosive gas at the hose opening. The
gas-venting hose must not be kinked or
blocked with dirt.
Danger of caustic burns
Battery acid is highly caustic, so:
Wear safety gloves and eye protection.
Do not tip the battery, or acid may spill
from the venting aperture.
First aid
If acid splashes into an eye, immediately
rinse with clean water for a few minutes.
See a doctor immediately.
If acid splashes onto skin or clothing,
neutralise immediately with soapsuds and
rinse with plenty of water.
If you accidentally drink acid, consult a
doctor immediately.
Disposal
Hand in the old battery at a battery
collection point.
Never dispose of an old battery with
domestic waste.
Minor Repairs 333
Charge state
A well-charged battery prevents starting problems
and has a longer service life.
Traffic density, speed limits, requirements
regarding noise, exhaust gas and fuel consump-
tion reduce the engine speed and, hence, the
generator output.
However, the large number of electrical loads has
markedly increased the demand for electrical
power.
In order to avoid unintended battery
discharge:
f Switch off unnecessary electrical loads in city
traffic, on short trips and in queues.
f Always withdraw the ignition key when leaving
the vehicle or
switch ignition off on vehicles that have
Porsche Entry & Drive.
f Avoid using the Porsche Communication
Management system and the audio system
when the engine is not running.
f For information on charging an exhausted
battery: Please observe the chapter
“CHARGING THE BATTERY” on Page 337.
Maintenance note
In the cold season in particular, it may become
necessary to recharge the battery from time to
time.
Battery care
f Keep battery surface clean and dry.
f Ensure that cell plugs and terminal clamps are
firmly secured.
Checking acid level
(only on low-maintenance batteries)
Check the acid level more frequently in the
summer months and in predominantly warm
countries.
f When topping up, use only clean vessels. In no
case may alcohol (e.g. window cleaner
residues) be permitted to enter the battery.
f Unscrew all plugs.
With the vehicle horizontal, the battery acid
must fill each cell up to the filler mark. These
filler marks are visible through the plug
openings as steps or lateral lugs in the battery.
f Top up with distilled water if necessary.
Do not use acid. Do not overfill.
Winter driving
The ability of the battery to deliver power
decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in the
winter months by the heated rear window, more
frequent use of additional lights, the blower and
the windscreen wipers, etc.
f Have the charge state of the battery checked
before winter begins.
Maintenance note
Keep the battery fully charged to prevent it from
freezing.
A discharged battery can freeze even at –10 °C,
but a fully charged one only freezes at –40 °C.
334 Minor Repairs
Laying up the vehicle
If the vehicle stands for long periods in the garage
or workshop, the doors and lids should be closed.
f Withdraw the ignition key and, if necessary,
disconnect the battery.
Notes on operation
f When the battery is disconnected, the alarm
system ceases to function.
If the vehicle was locked before the battery
was disconnected, the alarm will be triggered
when the battery is reconnected.
To deactivate the alarm system:
f Lock the vehicle and unlock it again.
Alarm system, central locking
f The status of the central locking and alarm
system is not changed by disconnecting the
battery.
Maintenance notes
Even if you put your vehicle out of operation, the
battery still discharges.
f To preserve its operating capability, charge the
battery about every 6 weeks.
f Check the battery acid level and top up with
distilled water if necessary.
f Store a battery that has been removed in a
dark, cool place, but not subject to frost.
Replacing the battery
The battery is subject to normal wear: its service
life depends greatly on the care you give it,
climatic conditions and the conditions of use
(distances, loads).
It is not possible to use the details on the battery
case to determine a comparable battery that
meets all the specific requirements of Porsche.
f Only replace the battery with one that satisfies
the specific requirements of your vehicle.
We recommend that you use a genuine
Porsche battery.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operation
After the battery is connected or after an exhaus-
tively discharged battery is charged, the PSM
warning light lights up on the instrument panel and

of the instrument panel to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
To do this, turn the ignition key or the control
unit (on vehicles with Porsche Entry & Drive) to
ignition lock position 2 twice.
2. With the vehicle stationary, perform a few
steering movements to the left and right and
then drive a short distance in a straight line
until the PSM warning light goes out and the
message is erased from the multi-purpose
display of the instrument panel.
3. If the warnings do not disappear, then have the
fault repaired.
Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
4. After the warnings disappear:
Stop the vehicle in a suitable place.
