Maintenance, Car Care

fAlways apply a fresh coating of suitable pre-
servative to unprotected 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 driv-
en 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.Stainless steel exhaust tailpipesStainless steel exhaust tailpipes can discolor due
to soiling, strong heat, and combustion residues.
The original polish can be achieved again using
commercially available metal polishing paste or
metal polish.Light alloy wheels fPlease see the chapter “WASHING” on
Page 225.
Warning!
Danger of accident resulting in serious per-
sonal injury or death if cleaning agents (e.g.
wheel cleaning agents) come into contact
with the brake discs.The resulting film on the brake discs can im-
pair braking performance.
fMake sure that no cleaning agent comes into
contact with the brake discs.
fIf cleaning agent has come into contact with
the brake discs, thoroughly clean the brake
discs with a strong jet of water.
fPaying attention to any road users behind you,
dry the brake discs by applying the brakes at
short intervals.
Metal particles (such as brass or copper in brake
dust) must not remain too long on alloy wheels.
Contact corrosion can cause pitting.
Cleaners with an oxide-removing effect or the
wrong pH value, as are commonly used for other
metals, as well as mechanical tools and products,
will damage the oxide layer and are therefore
unsuitable.
fUse only cleaners for alloy wheels
(pH value 9.5). Products with the wrong
pH value can destroy the protective layer
on the wheels.
We recommend Porsche cleaner for alloy rims.
fIf possible, wash the wheels every two weeks
with a sponge or washing brush. If the wheels
are exposed to road salt, grit or industrial dust,
weekly cleaning is necessary.
Door, roof, lid and window seals
Caution!
The lubricant coating on the inner door
seals, convertible top and hardtop seals may
be damaged by unsuitable cleaning and care
agents.
fDo not use any chemical cleaning agents or
solvents.
fDo not use any preservative agents.
fWash dirt (e.g. abrasion, dust, road salt and
grit) from all seals regularly using warm soapy
water.
fIf there is a risk of frost, protect the outer door
seals and lid seals against freezing into place
with a suitable care product.Headlights, lights, interior and exterior
plastic parts, adhesive filmsUse only clean water and a little dishwashing
detergent to clean light lenses, plastic headlight
lenses, plastic parts and surfaces.
Do not clean when dry.
Use a soft sponge or a soft, lint-free cloth. Gently
wipe the surface without applying too much
pressure.
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.

Practical Tips, Emergency Service
235
Tires/Wheels The original equipment tires and wheel rims on
your Porsche comply with all applicable Federal
Motor Vehicle Safety Standards.
For your safety remember the following:
– Wheel rims and wheel bolts are matched to fit
your Porsche.
– If you intend to use other than original equip-
ment wheels, be sure that they conform to
Porsche specifications for your model.
Only tires with the same make and with the
same specification code (e.g. “N0”, “N1”...)
can be mounted.
– The use of wheel rims and wheel bolts that do
not meet specifications of the original factory
installed equipment will affect the safe opera-
tion of your vehicle.
– Before you plan on exchanging wheels, or
snow tires already mounted on the wheel rims,
consult your authorized Porsche dealer. Your
dealer has the technical information necessary
to advise you which wheel rims and wheel bolts
are compatible with the original factory instal-
lations.
Danger!
Risk of loss of control and serious personal
injury or death.
fIf while driving, your vehicle experiences a sud-
den vibration or ride disturbance, and/or you
suspect that possible damage to your tires or
vehicle has occurred, you should immediately
reduce your speed without excessive use of
the brakes.
fStop the vehicle as soon as possible, and in-
spect the tires.
If you cannot determine the cause for the dis-
turbance, have your vehicle towed to the near-
est Porsche or tire dealer to have your vehicle
or tire(s) inspected.
fContinuing to operate the vehicle without cor-
rection could result in a loss of control and serious personal injury.
ExampleUniform Tire Quality GradingQuality grades can be found where applicable on
the tire sidewall between tread shoulder and max-
imum section width.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tr e a d w e a r
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specific govern-
ment test course.
For example, a tire graded 150 would wear one

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 sports cars 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.
If you notice that tires are wearing unevenly, con-
sult 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 care fAvoid 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.
Tire damage, puncture High-pressure cleaning units can damage the
tires.
fPlease see the chapter “HIGH-PRESSURE
CLEANING UNITS, STEAM CLEANERS” on
Page 224.
fCheck tires for imbedded material, cuts, punc-
tures, cracks and bulges (side wall) before driv-
ing off.
In case of tire damage, where it is uncertain wheth-
er there is a break in the ply with all its conse-
quences or tire damage caused by thermal or me-
chanical overloading due to loss of pressure or
any other prior damage, we recommend that the
tire be replaced for safety reasons.
If one faulty tire is replaced it should be noted that
the difference in tread depth on one axle must not
exceed 30%.
Handling inconsistencies may result.
fPerform a visual inspection if necessary.

Please see the chapter “SPACERS 911 CARRERA, 911 CARRERA S” on Page 255.
Tire and rim sizesExtensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche dealer has informa-
tion about approved tires and wheels and is happy to assist you.
If aftermarket tires and/or wheels are installed which are not approved by Porsche, the vehicle’s driveability, stability while
in motion and handling characteristics might be impaired. Since Porsche has no data on such combinations, Porsche cannot
stand behind the safety or durability of these aftermarket combinations.
