Maintenance and Car Care
Fuel Evaporation ControlFuel tank ventingThe evaporation chamber and the carbon canister
prevent fuel 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 storageWhen 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 systemWhen 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 InstructionsfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 250.
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.
Warning!
Risk of serious personal injury or damage to
the vehicle or property.
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 as well as damage to your
vehicle.
fKeep cleaning agents out of reach from
children.
fObserve all caution labels.
fAlways read directions on the container before
using any product. These directions may con-
tain information necessary to avoid personal
injury.
fDo 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.
fDo 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.
Moisture and road salt on brakes may affect
braking efficiency.
Test the brakes after each vehicle washing.

Maintenance and Car Care
Warning!
Moisture which gets on the brakes during a
car wash can reduce braking efficiency or
make the brake pull unevenly which could
increase the danger of an accident, causing
serious personal injuries or death.
fAfter washing the vehicle, test the brakes and
steering and briefly brake the discs dry.
When doing so, make sure that vehicles travel-ling behind you are not affected.
Automatic car washes
fPlease see the chapter “WIPER BLADES” on
Page 261.
Optional add-on parts or parts which project be-
yond the contours of the vehicle may be damaged
by design features (e.g. brushes) of automatic car
washes.The following parts are particularly
susceptible to damage:
– Windshield wipers and rear wiper (always
switch them off – wiper stalk in position0 – to
prevent them wiping unintentionally in intermit-
tent or sensor operation).
– Door mirrors (always fold in).
– External antennas (always unscrew).
– Roof Transport System (always remove com-
pletely).
– Off-road roof-mounted headlights (always
remove completely).
– Spoiler.
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage).
fPlease consult the operator before using
automatic car washes.
fWash and dry by hand all points not reached by
a car wash, such as door and lid seams or
door sills.
Note
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
Light alloy wheelsfPlease see the chapter “AUTOMATIC CAR
WASHES” on Page 272.
Danger!
Danger of accident resulting in serious
personal 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 impair 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.
Pitting may occur if metallic particles which cause
contact corrosion (e.g. brass or copper in brake
dust) are allowed to remain on the aluminum too
long.
fIf possible, wash the wheels with a sponge or
wash brush about every two weeks. In areas
where road salt or grit is spread on winter
roads or there is a lot of airborne industrial
dust, it is best to clean the wheels weekly.
The Porsche Light Alloy Wheel Cleaner
(ph-value 9.5) can be used for this
purpose.If the ph-value of the detergent is
incorrect, the protective coating on the
wheels will be destroyed.
Polishes which dissolve oxides, such as those
frequently used for other metals, or abrasive
tools or agents are unsuitable because they
break down the oxide film of the protective
coating and will cause discoloration of the
wheel.
fEvery three months, after cleaning, coat the
wheels with a car wax or non-corrosive grease
(e.g. vaseline).
Using a clean cloth thoroughly rub the grease
into the surface.
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.
Cleaning door, roof, lid and window seals
Caution!
The lubricant coating on the inner door seals
may be damaged by unsuitable cleaning and
care agents.
fDo not use any chemical cleaning agents or
solvents.
fDo not use any care agents.
fWash dirt (e.g. abrasion, dust, road salt or grit)
from all seals regularly using warm soapy
water. Do not use any chemical cleaning
agents or solvents.
fWhen there is a frost hazard, the outer door
seals and the lid seals can be protected
against freezing into place by a suitable care
product.

Minor Repairs
281
Notes on minor repairsTool kit
The tool kit is accommodated in the spare-wheel
well under the cover of the loadspace floor.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids, folding
wedges) are only supplied with the vehicle if the
vehicle comes with a collapsible spare wheel or
full-size spare wheel as standard. Your authorized
Porsche dealer will be pleased to advise you.
Tires/WheelsThe 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 and affect warranty
coverage.
– 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 installations.
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
inspect the tires.
If you cannot determine the cause for the
disturbance, have your vehicle towed to the
nearest Porsche or tire dealer to have your
vehicle or tire(s) inspected.
fContinuing to operate the vehicle without
correction could result in a loss of control and serious personal injury.
