Maintenance and Car Care 239
Exercise Extreme Caution when
Working on your vehicle
The engine compartment of any motor vehicle is
a potentially hazardous area. If you are not fully
familiar with proper repair procedures, do not
attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
Many vehicle fluids are highly flammable, e.g. fuel,
engine and transmission oil. Fuel vapors can
cause an explosion. When a battery is being
charged, highly explosive gases can develop.
f Do not smoke or allow an open flame around
the battery or fuel.
Pay attention to sparks, e.g. when coming into
contact with cables.
Keep a fire extinguisher close at hand.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially
cautious of devices such as hot water heaters
which ignite a flame intermittently.
f Only work on your vehicle outdoors or in a well
ventilated area.
Refill fluids, e.g. engine oil, brake fluid or coolant
are hazardous to health (poisonous, irritant,
caustic).
f Keep these fluids out of children's reach and
dispose of them in accordance with the
appropriate regulations.
f Only work on your vehicle outdoors or in a well
ventilated area.
Engine exhaust is dangerous if inhaled.
Engine exhaust fumes have many compo-nents
which you can smell. They also contain carbon
monoxide (CO), which is a colorless and odorless
gas.
Carbon monoxide can cause unconsciousness
and even death if inhaled.
f Only work on your vehicle outdoors or in a well
ventilated area.
The engine and surroundings components, the
exhaust system and coolant become very hot
when the engine is running.
The coolant reservoir is pressurized. Careless
opening of the coolant reservoir can lead to hot
coolant suddenly spraying out.
f Take care when working near hot parts of the
vehicle, in particular engine parts and parts of
the exhaust system.
f Before working in the engine compartment,
always switch the engine off and let it cool
sufficiently.
f Allow the engine to cool down before opening
the cap of the coolant reservoir and protect
your hands, arms and face from any possible
escape of hot coolant.
Take great care to ensure that hands, fingers,
articles of clothing (e.g. ties, sleeves, etc.),
necklaces or long hair cannot be caught up by the
radiator fans, drive belt or other moving parts.
The radiator fans can start or continue running as
a function of temperature, even with the engine
switched off.
f Exercise extreme care that parts of the body,
articles of clothing or jewelry do not get caught
in the radiator fan, drive belt or other moving
parts.
f Carry out work in these areas only with the
engine off and exercise extreme caution.
When the ignition is on, all cables and wires of the
ignition system carry a high voltage.
f Exercise special care when working on the
ignition system.

240 Maintenance and Car Care
If the vehicle is not secured, or incorrectly
secured, during repair work, it could move
unexpectedly or fall from the car jack or car lift.
f Be alert and cautious around the engine at all
times while it is running.
If you have to work on the engine while it is
running, always apply the electric parking
brake and put the gearshift lever in neutral or
the Tiptronic selector lever in position P or N.
f Always support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
Switch off level control of air suspension and
height adjustment.
Please see the chapter “LIFTING THE VEHICLE
WITH A LIFTING PLATFORM, TROLLEY JACK
OR STANDARD JACK” on page 274.
f Jack up the vehicle only at the specified
jacking points on the underside of the vehicle.
f Never start the engine when the vehicle is
jacked or lifted up. Vibration from the engine
could cause the vehicle to fall.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Withdraw ignition keys (switch ignition off in
vehicles that have Porsche Entry & Drive).
Information
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty
coverage.
f Some countries require additional tools and
special spare parts to be carried in your
vehicle. Please make enquiries before driving
abroad.
Technical Modifications
f Modifications may be carried out on your
vehicle only if approved by Porsche.
This ensures that your Porsche will remain
reliable and safe to drive, and that it will not be
damaged as a result of the modifications.
Your authorized Porsche dealer will be pleased
to advise you.
Information
f Only use genuine Porsche spare parts for your
vehicle or spare parts of similar quality which
have been manufactured according to the
specifications and production requirements of
Porsche. These parts are available from your
authorized Porsche dealer or a qualified
specialist workshop. Safety-related
accessories should only be used if they are
from the Porsche Tequipment range or are
tested and approved by Porsche. Your
authorized Porsche dealer will be pleased to
advise you and answer any questions you may
have.
However, the use of other parts or
accessories may adversely affect the safety
of your vehicle, and Porsche can take no
responsibility for any loss or damage caused
by their use.
Even if the supplier of other accessories or
parts is a recognized supplier, the safety of
your vehicle may still be affected if such items
are installed.
Due to the large variety of products offered in
the accessory market, it is not possible for
Porsche to inspect and approve every one.

f In addition, please note that the use of
replacement parts that are not genuine
Porsche parts or approved parts, or the use of
accessories not approved by Porsche may
also detrimentally affect your vehicle warranty.
f Check your vehicle regularly for signs of
damage. Damaged or missing aerodynamic
components, such as spoilers or underbody
panels, impair vehicle handling and must
therefore be replaced immediately.
Radiator fan
For information on radiator fans:
f Please see the chapter “RADIATOR FANS” on
page 245.
The fans can start running depending on the
temperature, even with the engine switched off.
f Exercise extreme care that parts of the body,
articles of clothing or jewelry do not get caught
in the radiator fan.
f Exercise extreme caution when working in the
area of the radiator fans.
Measurements on test stands
Performance test
Performance tests on roller-type test stands are
not approved by Porsche.
Brake tests
Brake tests must be performed only on roller-type
test stands.
The following limit values must not be exceeded
on roller-type test stands:
– Test speed 4.7 mph (7.5 km/h)
– Test duration 20 seconds
Testing the electric parking brake
Electric parking brake tests on the brake test
stand must only be performed with the ignition
switched on and with the manual gearshift lever
in neutral or the Tiptronic S selector lever in
position N.
The vehicle switches automatically to brake test
stand mode, in which the electric parking brake
can be tested.
The message “Electric parking brake in service
mode” appears on the multi-purpose display of the
instrument panel.
Balancing wheels on the vehicle
During finish balancing of the wheels, the entire
vehicle must be lifted and the wheels must be free
to turn.
Engine Oil
It is important to perform oil changes regularly in
accordance with the intervals specified in your
Maintenance Schedule.
Engine oil consumption
It is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil
level at all, even after 600 miles (1000 km) or
more. This is because the oil is gradually
becoming diluted with fuel or moisture, making it
appear that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an
expressway, making it then appear that oil is
excessively consumed after driving at high
speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater.
If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to
lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level
checked with every refueling.

Emission Control System
In the interest of clean air
Pollution of our environment has become a
problem that is of increasing concern to all of us.
We urge you to join us in our efforts for cleaner air
in controlling the pollutants emitted from the
automobile.
Porsche has developed an emission control
system that controls or reduces those parts of the
emission that can be harmful to our environment.
Your Porsche is equipped with such a system.
Porsche warrants the Emission Control System in
your new car under the terms and conditions set
forth in the Warranty Booklet.
You, as the owner of the vehicle, have the
responsibility to provide regular maintenance
service for the vehicle and to keep a record of all
maintenance work performed. To facilitate record
keeping, have the service performed by
authorized Porsche dealers. They have Porsche
trained technicians and special tools to provide
fast and efficient service.
To assure efficient operation of the Emission
Control System:
f Have your vehicle maintained properly and in
accordance with the recommendations
described in your Maintenance Booklet. Lack
of proper maintenance, as well as improper
use of the vehicle, will impair the function of
the emission control system and could lead to
damage.
f Do not alter or remove any component of the
emission control system.
f Do not alter or remove any device, such as
heat shields, switches, ignition wires, valves,
etc., which are designed to protect your
vehicle's emission control system. In addition
to serious engine damage, this can result in a
fire if excess raw fuel reaches the exhaust
system.
f Do not continue to operate your vehicle if you
detect engine misfire or other unusual
operating conditions.
Parking
The exhaust system becomes very hot when the
engine is running and remains hot for some time
after the vehicle is turned off. Flammable material
close to the exhaust system could ignite.
f Do not park or operate your vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other flammable materials.
f If your car catches on fire for any reason, call
the fire department. Do not endanger your life
by attempting to put out the fire.
Undercoating
Additional undercoating or rust protection agents
on or near the exhaust system can become too
hot when driving and ignite, causing a fire.
f Do not apply additional undercoating or rust
protection agent on or near the exhaust
manifolds, exhaust pipes, catalytic converters
or heat shields. During driving the substance
used for undercoating could overheat and
ignite.
How Emission Control Works
When an automobile engine is running, it uses
energy generated through the combustion of a
mixture of air and fuel. Depending on whether a
car is driven fast or slowly or whether the engine
is cold or hot, some of the fuel (hydrocarbons)
may not be burned completely, but may be
discharged into the engine crankcase or exhaust
system. Additonal hydrocarbons may enter the
atmosphere through evaporation of fuel from the
fuel tank. These hydrocarbons (HC), when
released into the air, contribute to undesirable
pollution.
In addition, carbon monoxide (CO) and oxides of
nitrogen (NOx) contribute to engine emissions.
They, too, are formed during the combustion
process and discharged into the exhaust system.
To reduce these pollutants, your Porsche is
equipped with a precisely calibrated fuel injection
system to assure a finely balanced air/fuel mixture
under all operating conditions.
Oxygen sensor
The oxygen sensor, installed in the exhaust pipe
continuously senses the oxygen content of the
exhaust and signals the information to an
electronic control unit. The control unit corrects
the air/fuel ratio, so the engine always receives an
accurately metered air/fuel mixture.
Crankcase ventilation
Through crankcase ventilation, undesirable
emissions from the engine crankcase are not
permitted to reach the outside atmosphere. These
emissions are recirculated from the crankcase to
the air intake system. From here the emissions
mix with the intake air and are later burned in the
engine.

250 Maintenance and Car Care
Catalytic converters
The catalytic converters are efficient “clean-up”
devices built into the exhaust system of the
vehicle. The catalytic converters burn the
undesirable pollutants in the exhaust gas before it
is released into the atmosphere.
The exclusive use of unleaded fuel is
critically important for the life of the
catalytic converters. Therefore, only
unleaded fuel must be used.
The catalytic converters will be damaged by:
– Push or tow starting the vehicle,
– Misfiring of the engine,
– Turning off the ignition while the vehicle is
moving,
– Driving until the fuel tank is completely empty,
– By other unusual operating conditions.
f Do not continue to operate your vehicle under
these conditions, since raw fuel might reach
the catalytic converters. This could result in
overheating of the converters. Federal law
prohibits use of leaded fuel in this car.
Fuel Economy
Fuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
f Have your vehicle tuned to specifications. Air
cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated to the correct
pressure.
f Always monitor your fuel consumption.
f Drive smoothly, avoid abrupt changes in speed
as much as possible.
f Avoid jack rabbit starts and sudden stops.
f Do not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
f Prolonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
f Switch off the engine if stationary for longer
periods.
f Any additional weight carried in the vehicle
reduces fuel economy. Always keep cargo to
a minimum and remove all unnecessary items.
f Organize your trips to take in several errands
in one trip.
f All electrical accessories contribute to

Operating Your Porsche in other
Countries
Government regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards.
Therefore, cars built for the U.S. and Canada differ
from vehicles sold in other countries.
If you plan to take your Porsche outside the
continental limits of the United States or Canada,
there is the possibility that:
– Unleaded fuel may not be available,
– Unleaded fuel may have a considerably lower
octane rating. Excessive engine knock and
serious damage to both engine and catalytic
converters could result,
– Service may be inadequate due to lack of
proper service facilities, tools or diagnostic
equipment,
– Replacement parts may not be available or
very difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or parts
availability.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about
shipping and forwarding requirements, as well as
current import and customs regulations.
Fuel
When the ignition is on, the fuel level is displayed
on the instrument panel.
f Please see the chapter “FUEL GAUGE” on
page 107.
f Fire, open flame and smoking are prohibited
when handling fuel.
Fuel and fuel vapors are hazardous to health.
f Avoid contact with skin or clothing, since injury
to your skin may occur.
f Do not inhale fuel vapors, since they may make
you ill and possibly cause death if inhalation is
prolonged and occurs in a closed space.
To prevent damage to the emission control system
and engine:
f Never drive the tank dry.
f Avoid high cornering speeds after the warning
lights have come on.
f Please see the chapter “FUEL ECONOMY” on
page 250.
To avoid permanent damage to the functionality of
the catalytic converters and oxygen sensors, use
unleaded fuel only.
The engine is designed to provide optimum
performance and fuel consumption if unleaded
premium fuel with 98 RON/88 MON is used.
If unleaded fuels with octane ratings of less than
98 RON/88 MON are used, the engine’s knock
control automatically adapts the ignition timing.
Porsche recommends that you use fuel with
at least 95 RON/85 MON in your vehicle.
The emission control system can be damaged in
various ways (e.g. fueling incorrectly, shortage of
fuel, tow-starting).
Please see the chapter “HOW EMISSION
CONTROL WORKS” on page 249.
Information
Information on the fuel quality can normally be
found on the pump.
If this is not the case, ask a gas station attendant.
If the recommended fuel is not available,
you can also use unleaded regular fuel (91 RON/
82.5 MON) in an emergency.
However, this could reduce performance and
increase fuel consumption.
f Avoid driving at full throttle.
In some countries the available fuel quality may
not meet requirements and can result in coking
around the intake valve.
In this case, the fuel may be mixed with the
additive sold and recommended by Porsche after
consulting an authorized Porsche dealer.

254 Maintenance and Car Care
Fuel Recommendations
Your Porsche is equipped with catalytic
converters and must use UNLEADED FUEL
ONLY.
Your engine is designed to provide optimum
performance and fuel economy using unleaded
premium fuel with an octane rating of 98 RON
(93
CLC or AKI)
. Porsche therefore
recommends the use of these fuels in your
vehicle.
Porsche also recognizes that these fuels may not
always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels
with octane numbers of at least
95 RON
(90 CLC or AKI)
, since the engine’s “Electronic
Oktane™ knock control” will adapt the ignition
timing, if necessary.
It is important to observe the regular service
intervals, and particularly the oil change intervals,
specified in the “Maintenance” booklet.
The use of UNLEADED FUEL ONLY is critically
important to the life of the catalytic
converters. Deposits from leaded fuels will
ruin the converters and make them
ineffective as an emission control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps that
dispense unleaded fuel have smaller nozzles. This
will prevent accidental pumping of leaded fuel into
cars with catalytic converters.
Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we
recommend you do not take your car to areas or
countries where unleaded fuel may not be
available.
Octane ratings
Octane rating indicates a fuel’s ability to resist
detonation. Therefore, buying the correct octane
gas is important to prevent engine “damage”.
The RON octane rating is based on the research
method. The CLC (U.S. Cost of Living Council
octane rating) or AKI (antiknock index) octane
rating usually displayed on U.S. fuel pumps is
calculated as research octane number plus motor
octane number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than
the RON rating:
For example: 95 RON equals 90 CLC or AKI.
Fuels containing ethanol
Do not use any fuels containing more than
10 percent ethanol by volume.
We recommend, however, to change to a different
fuel or station if any of the following problems
occur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially
at high altitude or at high temperature.
– Engine malfunction or stalling.
Fuel Evaporation Control
Fuel tank venting
The evaporation chamber and the carbon canister
prevent fuel vapors from escaping to the
atmosphere at extreme high outside
temperatures, when driving abruptly around
curves and when the car is parked at an incline or
in any other nonlevel position.
Vapor control system and storage
When the fuel tank is filled, vapors are collected in
the evaporation chamber by a vent line leading the
vapors to the carbon canister where they are
stored as long as the engine does not run.
Purge system
When the engine is running, the fuel vapors from
the canister will be mixed with fresh air from the
ambient air of the canister. This mixture will be
directed to the intake air housing by the tank vent
line, mixed with the intake air and burned during
normal combustion.

Car Care Instructions
f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on page 239.
Regular and correct care helps to maintain
the value of your car and is also a
precondition for the New Vehicle Warranty
and the Anti Corrosion Warranty.
Your authorized Porsche dealer has specially
developed car-care products from the
Porsche program available either singly or
as complete car-care sets. They will be
pleased to help you select suitable products.
Whether you use Porsche products or other
commercially available cleaning agents first
make sure of their correct application.
A Porsche that is well-cared for can look like new
for years. It all depends on the amount of care the
owner is willing to give the car.
Cleaning agents may be hazardous to your health.
Most chemical cleaners are concentrates which
require dilution. High concentrations might cause
problems ranging from irritation to serious injury.
f Keep cleaning agents out of reach from
children.
f Observe all caution labels.
f Always read directions on the container before
using any product. These directions may
contain information necessary to avoid
personal injury.
f Do not use fuel, kerosene, naphtha, nail polish
remover or other volatile cleaning fluids. They
may be toxic, flammable or hazardous in other
ways. Only use spot removing fluids in a well
vented area.
f Do not clean the underside of chassis,
fenders, wheel covers, etc., without protecting
your hands and arms as you may cut yourself
on sharp-edged metal parts.
Risk of damage to the vehicle or property from
cleaning agents.
f Observe all caution labels.
High-pressure cleaning equipment,
steam cleaners
Risk of damage as a result of using high-pressure
cleaning equipment, steam cleaners or similar.
High-pressure cleaning equipment, steam
cleaners or similar can damage the following
components:
– Tires,
– Logos, emblems,
– Painted surfaces
– Wheel arch extensions,
– Alternator, valve covers,
– ParkAssist sensors,
– Radar sensor for adaptive cruise control,
– Rearview camera.
f Always read the operating instructions
provided by the equipment manufacturer.
f Always cover the lid of the brake fluid reservoir
prior to cleaning. Never point the cleaning jet
directly at the lid.
f When cleaning with a flat-jet nozzle or
a so-called “dirt blaster”, maintain a minimum
distance of 21 in. (50 cm).
f Never use high-pressure cleaning equipment,
steam cleaners, etc. with a round-jet nozzle.
High-pressure cleaning equipment with a round
nozzle will damage your vehicle. The tires are
particularly susceptible to damage.
f Do not point the cleaning jet directly at any
of the aforementioned components.

Decorative film
Risk of damage due to separation of the
decorative film when using high-pressure cleaning
equipment, steam cleaners or similar cleaning
equipment.
f Do not use high-pressure cleaning equipment,
steam cleaners, etc. to clean decorative films.
Care of door lock
f To prevent the door lock from freezing during
the cold season, cover the lock barrel with
suitable adhesive tape while washing the
vehicle.
If the lock still freezes, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.
Car washing
The best protection for the vehicle from the
damaging effects of the environment is frequent
washing and preservation.
The longer road salt, road dust, industrial dust,
insect remains, bird excrement, and tree
exudations (e.g. resin, pollen), etc. are allowed to
remain on the bodywork, the more harmful their
effect.
Observe the following points in order to ensure
that the vehicle is washed thoroughly without
damaging the paintwork:
f The underside of the vehicle should also be
thoroughly washed at the end of the gritting
season at the latest.
f Wash your vehicle only at sites provided for
this purpose to prevent soot, grease, oil and
heavy metals from entering the environment.
f Dark colors are slightly more susceptible to
scratching and require particularly careful
paint care.
Dark paints make even the smallest surface
blemishes (scratches) more conspicuous than
lighter colors.
f Do not wash your Porsche in direct sunlight or
when its body is hot.
f When washing by hand, use a car shampoo,
plenty of water, and a soft sponge or washing
brush.
We recommend Porsche car shampoo.
f Start washing the vehicle by thoroughly
wetting the paintwork and rinsing the heavy
dirt off.
f After washing the vehicle, rinse it thoroughly
with water and rub it dry with chamois-leather.
Do not use the same chamois for rubbing dry
as you use for cleaning the windshield and
windows.
Reduced or uneven braking action may be caused
by wet brakes.
f After washing the vehicle, test the brakes and
steering and briefly brake the disks dry.
When doing so, make sure that vehicles
traveling behind you are not affected.
Cleaning in car washes
Optional add-on parts or parts that project beyond
the contours of the vehicle may be damaged by
design features of car washes.
The following parts are particularly at risk:
– Windshield wipers and rear wiper (always
switch them off – wiper stalk in position 0 –
to prevent them wiping unintentionally in
intermittent or sensor operation).
– Door mirrors (always fold in).
– External antenna (always unscrew).
– Roof transport system (always remove
completely).
– Spoiler.
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage).
f Please consult the operator before using
automatic car washes.
f All parts not reached by a car wash, such as
door and lid seams or door sills, must be
washed and polished by hand.
Information
Automatic car washes spray water at odd angles
and high pressures, which are not seen in normal
driving. Therefore, water can sometimes find its
way into the passengers compartment during or
shortly after the car wash.

Maintenance and Car Care 257
Paint care
In order to protect the paintwork on your vehicle in
the best possible way against mechanical and
chemical damage, you should:
– Preserve it regularly,
– Polish it if necessary,
– Remove spots and stains,
– Repair damaged paintwork.
General Notes
f Never rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage the
paintwork.
f Do not treat matt-painted components with
preservatives or polishes as these remove the
matt effect.
Preservation
The paint surface becomes dull over time due to
weathering.
f Preserve paint regularly.
f Apply paint preservative after washing the
vehicle and polish it smooth to preserve the
paintwork.
This keeps the paint shiny and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating the
paint.
Polishing
Only when the original shine can no longer be
obtained using preservatives should paint polish
be used to clean the paint.
We recommend Porsche paint polish.
Removing spots and stains
f Remove tar spatters, traces of oil, insects etc.
as soon as possible using an insect remover,
as they discolor the paint if left to work on it
over time.
f Wash the treated areas carefully afterwards.
Repairing minor paint damage
f Have minor paint damage (cracks, scratches
or stone damage) repaired immediately by
your authorized Porsche dealer before
corrosion begins.
If traces of corrosion have already formed, these
must be thoroughly removed. An anti-corrosion
primer must then be applied to these spots,
followed by top-coat paint.
Paint data can be found on the vehicle data
carrier.
f Please see the chapter “VEHICLE DATA BANK”
on page 307.
Cleaning the engine compartment
Risk of damage, e.g. to the alternator, electrical
components and plug connections, painted
surfaces and valve covers.
f Never use high-pressure cleaners with
a round-jet nozzle.
f Always observe a minimum distance of 21 in.
(50 cm).
f Always cover the lid of the brake fluid reservoir
prior to cleaning with a high-pressure cleaner.
Never point the cleaning jet directly at the lid.
f Do not point the cleaning jet directly at any of
the aforementioned components.
Cleaning windows
f Clean all windows regularly, inside and out,
with Porsche window cleaner.
f Make sure not to damage the heating filaments
of the rear window and the TV antenna of the
side window when cleaning.
f Do not use the same chamois for painted
surfaces and for drying the windows.
Preservative residues could reduce
transparency.
f Remove insect residues with insect remover.
Information
The front side windows have a water-repellent
(hydrophobic) coating, which prevents soiling of
the windows.
This coating is subject to natural wear and can
be renewed.
f Please contact your authorized Porsche
dealer.
NOTICE
258 Maintenance and Car Care
Care of windshield wiper blades
Windshield wiper blades that are in perfect
condition are vital for a clear view.
f Please see the chapter “WIPER BLADES” on
page 248.
f Have the wiper blades replaced twice per year
(before and after the cold season) or if wiper
performance deteriorates or the blades are
damaged.
f Clean the wiper blades with window cleaner at
regular intervals, especially after washing the
vehicle in a car wash.
We recommend Porsche window cleaner.
If wiper blades are very dirty (e.g. covered with
insect remains), they can be cleaned with
a sponge or cloth.
If the wiper blades rub or squeak, this may be due
to the following:
– If the vehicle is washed in an automatic car
wash, wax residues may adhere to the
windshield. These wax residues can be
removed only by using window cleaner
concentrate.
f Please see the chapter “WASHER FLUID” on
page 246.
Contact your authorized Porsche dealer for more
information.
– The wiper blades may be damaged or worn.
f Have damaged or worn wiper blades replaced
immediately.
Repairing the underbody protection
The underside of your car is durably protected
against chemical and mechanical influences.
As it is not possible to exclude the risk of damage
to this protective coating in day to day driving, it
is advisable to have the underside of the car
inspected at certain intervals - preferably before
the start of winter and again in spring - and the
undercoating restored as necessary.
Your authorized Porsche dealer is familiar with the
bodyseal treatment procedures and has the
necessary equipment for applying factory
approved materials. We recommend that you
entrust them with such work and inspections.
Unlike conventional spray oils, undercoating and
rust-proofing compounds based on bitumen or
wax do not attack the sound-proofing materials
applied at the factory.
The exhaust system becomes very hot when the
engine is running. Flammable material close to the
exhaust system could ignite. Additional
undercoating or rust protection agents on or near
the exhaust system can become too hot when
driving and ignite.
f Do not apply additional undercoating or rust-
proofing on or near the exhaust manifold,
exhaust pipes, catalytic converters or heat
shields. During driving the substance used for
undercoating could overheat and ignite.
f Before applying fresh underseal, carefully
remove deposits or dirt and grease. Once it
has dried, the new undercoating compound
forms a tough protective coating which
provides efficient rust-proofing of the floor
panels and components.
f Always apply a fresh coating of suitable
preservative to unprotect areas after cleaning
the underside of the body, the transmission,
the engine or carrying out repairs to under-
body, engine or transmission components.
Effective rust-proofing is particularly important
during the cold weather season. If your car is
driven frequently in areas where salt has been
spread on the roads, the whole engine
compartment should be cleaned thoroughly after
the winter to prevent salt from causing any lasting
damage. A full under-body wash should also be
performed at the same time.
Cleaning headlights, lights, interior
and exterior plastic components,
adhesive films, radar sensor for adaptive
cruise control and rearview camera
Observe the following points:
f Use only clean water and a little dishwashing
liquid or interior window cleaner to clean
headlights, lights, plastic components and
surfaces.
Use a soft sponge or a soft, lint-free cloth.
Information
An interior window cleaner can also be used to
clean plastic surfaces (always read the cleaning
instructions on the container!).
We recommend Porsche interior window cleaner.
f Gently wipe the surface without applying too
much pressure.
f Do not clean when dry.
f Never use other chemical cleaners or
solvents.
f Rinse cleaned surfaces with clear water.
