Controls, Safety, Instruments fDo not add any additional coverings or stickers
to the steering wheel or in the area of the pas-
senger airbag and side airbags. Doing so may
adversely affect the functioning of the airbag
system or cause harm to the occupants if the
airbag system should deploy.
fDo not undertake any wiring for electrical ac-
cessory equipment in the vicinity of the airbag
wiring harnesses. Doing so may disable the air-
bag system or inadvertant inflation.
fIf the warning light comes on, the airbag sys-
tem should be repaired immediately by your
authorized Porsche dealer.
fAlways keep feet in the footwell while driving.
Do not put feet on the dashboard or the seat
area.
Note
Airbag components (e.g. steering wheel, door
trim) may be disassembled only by an authorized
Porsche dealer.
When disposing of a used airbag unit, our safety
instructions must be followed. These instructions
can be obtained at any authorized Porsche dealer.Faults are indicated by a warning light on the ta-
chometer and a message on the instrument
panel’s multi-purpose display.
fIn the following cases you should immedi-
ately consult an authorized Porsche
dealer in order to assure the airbag sys-
tem is functioning properly:
– If the warning light does not light up when the
ignition is switched on or
– If the warning light does not go out once the
engine is running or
– If the warning light appears while driving.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 106.
Airbag maintenanceIn order to ensure long-term functioning, the air-
bag system must be inspected by an authorized
Porsche dealer at the intervals recommended in
your Maintenance Booklet.
Important information
If you sell your Porsche, notify the purchaser that
the vehicle is equipped with airbags, and refer
them to the chapter, “Airbag Systems“, in the
owner's manual (safety and disposal rules).
Further information on the airbag system can be
found on stickers attached to the sun visors, as
well as on all airbag components.
For special recommendations on the use of child
restraints:
fPlease observe the chapter “CHILD RES-
TRAINT SYSTEMS” on Page 47.DisposalfNon-ignited gas alternators, or whole vehicles
or subassemblies with airbag units, must not
be disposed of as “normal” scrap or waste or
put into any other form of end storage.
Your authorized Porsche dealer will be able to
give you details about disposal.

Tips on driving
fAvoid high engine speeds (max. 2,500 rpm).
fDo not perform manual gear changes when
driving, and try to avoid stopping.
Moving off in the water can be difficult due to
the high resistance and the loose surface in-
volved.
fStart the water crossing at a shallow place at
walking speed.
fAfter checking the body of water, take the
shortest path through it.
fNever drive into the water at high speed. The
resulting “bow wave” could damage the engine
and its accessories.
fAdjust your driving style to the unfamiliar sur-
roundings.
fCross the body of water slowly and at a con-
stant speed.
fNever turn around when crossing a body of wa-
ter.
fIf it is not possible to cross the body of water,
the car must be backed out of it in reverse
gear.
The servo pump and alternator can fail if the car is
driven through water for an extended period.
fIf the servo pump fails, substantially more
force will have to be exerted in order to steer. Maintenance note
The car requires a special check after the water
crossing.
fRemove mud from the tire tread.
fBriefly brake the brakes dry after driving
through the water.
HumpsfPlease observe the chapter “GROUND CLEA-
RANCE” on Page 355.
Note on operation
fActivate Low Range and engage differential
locks if necessary.
Tips on driving
fJust before reaching the hump, ease off the ac-
celerator slightly and use the car's momentum
to cross the hump. This will prevent the car
from jumping over the hump and landing on the
following downward slope at an excessive
speed.
fAvoid high engine speeds (max. 2,500 rpm).

High-pressure cleaning units
Warning!
High-pressure cleaning units 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 observe 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 50 cm
(21 in.).fNever use high-pressure cleaning units with a
round-jet nozzle.
A high-pressure cleaning unit with round nozzle
will damage your vehicle. The tires are particu-
larly susceptible to damage.
fDo not point the cleaning jet directly at any of
the aforementioned components.
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 (res-
in, pollen), etc. are allowed to remain on the body-
work, 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 scratch-
ing because of the composition of their pigments
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 wa-
ter to rinse away loose dirt.
fAfter washing, rinse the car with plenty of wa-
ter 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.

Maintenance, Car Care
Cleaning the engine compartment
Caution!
Risk of damage, e.g. to the alternator, paint-
ed surfaces, and the valve covers.
fNever use high-pressure cleaning units with a
round-jet nozzle.
fAlways maintain a minimum distance of 50 cm
(21 in.).
fAlways cover the lid over the brake fluid reser-
voir prior to cleaning with a high-pressure
cleaner. Never point the cleaning jet directly at
the lid.
fDo not point the cleaning jet directly at any of the aforementioned components.
Note on operation
If the vehicle is driven off-road frequently and after
driving on salted or gritted roads:
fClean the engine compartment regularly.
WindowsThe road dust which settles on the windshield and
windows contains particles of tire rubber and oil
residue. The interior trim and upholstery release
particles, particularly in strong sunlight, which col-
lect on the insides of the windows. These deposits
are augmented by impurities in the air which en-
ters the car through the fresh air vents.
fClean all windows regularly, inside and outside,
with Porsche window cleaner.
fMake sure not to damage the TV antenna in the
side window when cleaning.
fIf you use a chamois leather for the windows,
do not use it for paintwork as it will otherwise
pick up a certain amount of preservative or pol-
ish and could smear the windows and thus im-
pair vision.
fRemove dead insects with insect remover.
Wiper bladesWiper blades that are in perfect condition are vital
for a clear view.
fReplace the wiper blades twice per year (be-
fore and after the cold season) or whenever
wiper performance deteriorates.
fPeriodically clean wiper blades with Porsche
window cleaner, especially after the vehicle
has been washed in a car wash.
If they are very dirty (e.g. with insect remains),
they can be cleaned with a sponge or cloth.
