Luggage Compartment, Loadspace and Storage If aftermarket systems are installed by non-dealer-
ship technicians or outside the selling dealer,
problems may result. Installation of aftermarket
equipment is not covered under the New Car
Warranty.
fConsult your authorized Porsche dealer about
the installation of non Porsche approved equip-
ment.
Reception quality
The reception quality of your car telephone will
change constantly when you are driving. Interfe-
rence caused by buildings, landscape and wea-
ther is unavoidable. It may become particularly
difficult to hear when using the hands-free function
due to external noise such as engine and wind
noise.
Automatic car-wash
fUnscrew external antennas before using an au-
tomatic car-wash.
Porsche Communication
Management (PCM)
Warning!
There is danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do so safely.
fCarry out any complicated operating or setting
procedures only with the vehicle stationary.
fIf it is necessary to operate these components
while the vehicle is in motion, use the function keys on the multi-functional steering wheel.
fRefer 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.
Satellite radioYou must have the satellite radio activated before
you can put it into operation. You will need a
contract with a provider in order to use this radio.
fRefer to the separate radio operating instruc-
tions before putting into operation.

Maintenance and Car Care
271
High-pressure cleaning equipment, steam
cleaners
Warning!
High-pressure cleaning equipment, steam
cleaners or similar can damage the following
components:
–Tires
– Logos, emblems
– Painted surfaces
– Widened fenders
– Lock and latch of the removable towing attach-
ment
– Seals of the electrically retractable ball hitch
– Alternator, valve covers
– ParkAssist sensors
fPlease see the operating instructions from the
unit manufacturer.
fAlways cover the lid over the brake fluid reser-
voir prior to cleaning. Never point the cleaning
jet directly at the lid.
fWhen cleaning with a flat-jet nozzle or the like,
maintain a minimum distance of 21 in.
(50 cm).fNever 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.
fDo not point the cleaning jet directly at any of
the aforementioned components.
Decorative foils Caution!
Risk of damage due to separation of the de-
corative foils when using high-pressure clea-
ning equipment, steam cleaners or similar
cleaning equipment.
fDo not use high-pressure cleaning equipment, steam cleaners, etc. to clean decorative foils.
Door lockfTo prevent the door lock from freezing during
the cold season, cover the lock barrel with a
suitable adhesive tape during washing.
Should the locks freeze, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.
WashingThe best protection for the car from the damaging
effects of the environment is frequent washing and
preservation. The underside of the car should also
be thoroughly washed for cinders, salt or sanding
at winter‘s end.
The longer salt, road dust, industrial dust, insect
remains, bird excrement, and tree exudations
(resin, pollen), etc. are allowed to remain on the
bodywork, the more serious is their harmful
effect.
New cars should be washed carefully with plenty
of clear water to protect the new paint work.
Dark paint finishes show up the smallest of sur-
face damage (e.g. scratches) more readily than
lighter colors.
Dark colors are also more susceptible to scrat-
ching because of the composition of their pig-
ments and require particularly careful paint care.
fDo not wash your car in bright sunlight or while
the bodywork is still hot.
fWhen washing by hand, use abundant water, a
soft sponge or wash brush and Porsche car
shampoo.
fBegin by spraying the body thoroughly with
water to rinse away loose dirt.
fAfter washing, rinse the car with plenty of
water and then dry with a chamois leather.
Do not use the same chamois leather for
drying as you use for cleaning the windshield
and windows.

Tire lifeTire life depends on various factors, i.e., road sur-
faces, traffic and weather conditions, driving
habits, type of tires and tire care.
fInspect your tires for wear and damage before
driving off. If you notice uneven or substantial
wear, wheels might need alignment or tires
should be balanced or replaced.Tire wearThe original equipment tires on your Porsche have
built-in tire wear indicators. They are molded into
the bottom of the tread grooves and will appear as
approximately 1/2 in. (12 mm) bands when the
tire tread depth is down to 1/16 of an in (1.6 mm).
When the indicators appear in two or more adja-
cent grooves, it is time to replace the tires. We
recommend, however, that you do not let the tires
wear down to this extent.
Worn tires cannot grip the road surface properly
and are even less effective on wet roads.
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.
Danger!
Driving on worn tires can result in loss of con-
trol of the vehicle and could cause serious
personal injuries or death.
fDo not drive with worn tires or tires showing
cuts or bruises as they may lead to sudden
deflation and loss of control which could cause
severe personal injury.
fSpecialized high performance tires on high
performance sport utility vehicles exhibit more
wear than those on a family sedan, or even a
high performance sedan.
Therefore, it is important to check your tire
pressure and condition at least every two weeks.
fIf you notice that tires are wearing unevenly,
consult your Porsche dealer.
Uneven wear may not always be due to improper
wheel alignment. It can be the result of individual
driving habits such as cornering at high speeds. If
the tire pressure is not checked and adjusted
regularly, abnormal tire wear can also occur.
Tire carefAvoid damaging tires and wheel rims.
fIf you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
fCheck tires for uneven wear and damage
before driving off.
fRemove imbedded material.
fReplace worn or damaged tires immediately.
fKeep oil, fuel, brake fluid, etc. away from tires.
fReplace missing valve stem caps.
fKeep tires inflated correctly.
fWash tires when washing the vehicle. Also
clean inner side of wheels.
fDo not use abrasive cleaners when washing
the wheels.
fCheck wheel rims for corrosion.
fRemove road salt, if driving in winter.

Parking at the curb
Danger!
Hard impacts against curbs (or traffic
islands) are dangerous and may cause hid-
den tire damage which is not noticeable until
later. Such damage can result in accidents at
high speeds causing serious personal injury
or death. Depending on the force of impact,
the edge of the rim can also be damaged.
fIf you are in doubt, have the wheel checked by
an expert, particularly if you suspect damage
on the inside.
fIf you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle. Exercise care when parking along curbs.
Maintenance Note
Tire repairs are not permissible under any circum-
stances.
Wheel alignment, wheel balancingAs a precaution, have wheels with summer tires
balanced in the spring, and those with mud and
snow tires before winter. Unbalanced wheels may
affect car handling and tire life.
Only the specified weights may be used for wheel
balancing. Self-adhesive weights must not come into contact
with cleaning agents, since they could drop off.
Uneven tread wear indicates wheel imbalance. In
this event, the vehicle should be checked at an
authorized Porsche dealer.
Danger!
If, during a trip, uneven running or vibrations
occur that could be caused by damage to
tires or the car, the speed must be reduced
immediately, but without braking sharply. If
you continue your trip without having the
cause of the fault remedied, you might lose
control of your vehicle which could cause
serious personal injury or death.
fStop the vehicle and check the tires.
fIf no cause for the fault can be found, drive ca-
refully to the nearest authorized Porsche dea-ler.
Wheels with Tire Pressure Monitoring
(TPM) sensorsBefore changing wheels, make sure that the
wheels are compatible with your vehicle’s TPM.
fCheck this with your authorized Porsche dea-
ler.
Removing and storing tiresfAfter changing, adjust tire pressure and torque
wheel bolts diagonally.
Please see the chapter “CHANGING WHEELS”
on Page 294.
fStore tires in a cool and dry place. Rotate peri-
odically to avoid flat spots.
fAvoid contact with petrol, oil and grease.
Tires must always remain on the same side of
the vehicle.
When wheels are removed, the direction of
rotation and position of each wheel should be
marked.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with
their marking.
The perception that tire durability and perfor-
mance are not affected by storage and age is
unfounded.
Chemical additives, which make the rubber elas-
tic, lose their effectiveness over the course of
time and the rubber becomes brittle and cracks.
Therefore, the tires, especially the spare tire,
should be inspected from time to time.

Minor Repairs Note
Under no circumstances should tires older than
6 years be used on your Porsche.
The age of the tire can be obtained from the “DOT”
code number. If, for example, the last three num-
bers read 1208, then the tire was produced in the
12th week of 2008.
Snow tiresThe installation of Porsche approved winter tires is
recommended.
Use Porsche approved winter tires for grip on
snow and ice. For optimum performance, stud-
ding can be considered.
Check with your local Motor Vehicle Bureau for
possible restrictions.
Danger!
Risk of loss of control and damage to the
vehicle as well as serious personal injury or
death.
The standard tires profile and rubber mixture
are optimized for wet and dry driving condi-
tions, and may not prove favorable for snow
conditions.
fInstall winter tires before driving in such condi-tions.Before mounting winter tires, consult with your
Porsche dealer. He has the technical information
necessary to advise you on wheel and tire compa-
tibility.
fSnow tires should have the same load capacity
as original equipment tires and should be
mounted on all four wheels.
Winter tires with studs should be run at mode-
rate speeds when new in order to give the
studs time to settle.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases increases risk of a tire failure and
resulting loss of control. Furthermore, low
tire pressure increases rate of wear of the
affected tires and cause damage.
Tires with badly worn treads and studs are
very dangerous and could cause accidents
resulting in serious personal injuries or
death.
fMake sure they are replaced immediately.
fDo not exceed the winter tire speed rating.
Snow tires do not have the same degree of trac-
tion on dry, wet or snowfree roads as normal tires.
Furthermore, snow tires wear rapidly under these
conditions.Maintenance Note
We recommend fitting winter tires on the vehicle at
temperatures below 45 °F (7 °C) since the driving
performance of summer tires is reduced at low
temperatures. Summer tires may be permanently
damaged at extremely low temperatures.
Winter tires do not fulfill their purpose if the tread
depth is less than 5/32 in. (4 mm).
Comply with all state and local laws gover-
ning snow tire and tread depth requirements.
Danger!
Risk of accident and serious personal injury
or death due to excessive speed.
fAlways check the maximum speed rating on
the tire sidewall on any tire on the vehicle.
fNever exceed the maximum speed rating of the tires.
Wheel change
fWhen wheels are removed, mark the direction
of rotation and position of each wheel.
Example: FR (front right), FL, RR and RL.
fAlways fit the wheels in accordance with the
markings.
