transmission and running-gear control systems
are available for off-road driving:
– Off-road program Low Range
–Off-road PSM
–Off-road ABS
– Center differential lock
– Rear differential lock
fPlease see the chapter “POWER-TRANSMISSI-
ON AND RUNNING-GEAR CONTROL SYSTEMS”
on Page 181.Before driving offTires
fCheck tread depth and tire pressure.
fCheck for damage and remove any foreign
objects (e.g. stones) from the tread.
fReplace missing valve caps.
Rims
fReplace dented or damaged rims before
driving off road.
Vehicles with SportDesign package
Caution!
Risk of damage. On vehicles with Sport-
Design package, front, rear, and side
member trim are painted. Off-road driving
can seriously damage these trim parts.
fWhen driving off-road, make sure these parts
are not damaged.
fMake sure there is sufficient clearance
between obstacles and the underside of the
vehicle.
fAvoid driving through water.
fDo not use side member trims or rear wheel spoilers as a running board.
After driving off roadOff-road driving places a greater burden on the
vehicle than does normal driving on roads.
We recommend inspecting the vehicle after off-
road driving. Potential damage poses an accident
risk and impairs driving comfort. Damage on the
car is recognized in good time if the car is
checked.
Caution!
Car damage poses an accident risk for the
vehicle occupants and other road users.
fIn cases of doubt, have your vehicle checked
by your authorized Porsche dealer.
fExamine tires for signs of damage such as
cuts, tears, bulges or foreign objects stuck in
the tread.
Replace a damaged tire if necessary.
fHave any damage to your vehicle repaired by an authorized Porsche dealer without delay.

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.

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
273
PaintfNever rub a dusty car with a dry cloth since
dust particles are abrasive and could dull and
damage the surface finish.
The paintwork of your car is exposed to all types
of mechanical and chemical conditions, particular-
ly climatic ones such as bright sunlight, rain, frost
and snow. Ultraviolet light, rapid changes in tem-
perature, rain, snow, industrial dust and chemical
deposits constantly attack the paint which is only
able to withstand such exposure in the long term
if it is given regular care and attention.
fDo not apply silicone polishes to the windshield
or window.
fDo not treat matt-painted components with
preservatives or polishes, otherwise the matt
effect will be lost.
Preservation
The paint surface becomes dull over time due to
weathering. It is therefore necessary to preserve
the paint regularly.
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.
Provided it is washed and treated with preserva-
tive regularly, the brand new finish of your car will
be retained for years to come.
fSimply apply paint preservative after washing
the car and polish it smooth.Polishing
Do not resort to using Porsche polish until it
becomes evident that the normal preservatives no
longer produce the desired finish.
Removing spots and stains
fRemove tar stains, grease, oil spots and dead
insects etc. as soon as possible with Insect Re-
mover. They can cause discoloration if allowed
to remain on the paintwork.
fWash the affected area immediately after
treating it.
Minor paint damage
fHave minor paint damage, such as scratches,
scores or chips caused by flying stones,
repaired immediately by your authorized
Porsche dealer before corrosion begins.
However, if there are already traces of corrosion,
they must first be removed carefully and
thoroughly. Coat the area with a rust-proofing
primer and finish off with a top coat. The paint
code and color number are found on the data bank
in the Maintenance booklet and on the vehicle’s
data bank.
fPlease see the chapter “DATA BANK” on
Page 347.
Cleaning the engine compartment
Caution!
Risk of damage, e.g. to the alternator,
painted surfaces, and the valve covers.
fNever use high-pressure cleaning equipment
with a round-jet nozzle.
fAlways maintain a minimum distance of 21 in.
(50 cm).
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 car is driven off-road frequently and after
driving on salted or gritted roads:
fClean the engine compartment regularly.

Maintenance and Car Care
275
UndercoatingThe 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 ne-
cessary 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.
Warning!
Danger of fire resulting in serious personal
injury or death.
fDo 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.fBefore applying fresh underseal, carefully re-
move deposits or dirt and grease. Once it has
dried, the new undercoating compound forms
a tough protective coating which provides effi-
cient rust-proofing of the floor panels and com-
ponents.
fAlways apply a fresh coating of suitable pre-
servative to unprotect areas after cleaning the
underside of the body, the transmission, the
engine or carrying out repairs to underbody,
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 compart-
ment 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 parts, adhesive filmsObserve the following points:
fUse only clean water and a little dishwashing
detergent or interior window cleaner to clean
headlights, lights, plastic parts, adhesive films
and surfaces.
Use a soft sponge or a soft, lint-free cloth.
Note
An interior window cleaner can also be used to
clean plastic surfaces (observe cleaning instruc-
tions on the container!).
We recommend the Porsche interior window
cleaner.
fGently wipe the surface without applying too
much pressure.
fDo not clean when dry.
fNever use other chemical cleaners or
solvents.
Rinse cleaned surfaces with clear water.

Minor Repairs
285
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.

Minor Repairs
Tire damage, puncturefPlease see the chapter “HIGH-PRESSURE
CLEANING EQUIPMENT, STEAM CLEANERS”
on Page 271.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires.
fCheck tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
fAfter driving off road, examine tires for signs
of damage such as cuts, tears, bulges or
foreign objects stuck in the tread. Replace a
damaged tire if necessary.
fCross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
fIn cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Porsche dealer.In case of tire damage, where it is uncertain
whether there is a break in the ply with all its con-
sequences or tire damage caused by thermal or
mechanical overloading due to loss of pressure or
any other prior damage, we recommend that the
tire be replaced for safety reasons.
I f o n e f a u l t y t i re i s re p l a c e d i t s h o u l d b e n o t e d t h a t
the difference in tread depth on one axle must not
exceed 30%. Handling inconsistencies may result.
fPerform a visual inspection if necessary.
Tire replacementsfUse only tire makes and types tested by
Porsche.
If you do not use a Porsche recommended
replacement tire, make sure that you
purchase your new tires from a reputable tire
dealer and that the dealer complies with all
manufacturers warnings for those tires.
Only tires with the same manufacturer and
with the same specification code (e.g. “N0”,
“N1”...) should be mounted on the vehicle.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Tires should be replaced no less than on one axle
at the time. Only tires of the same make and type
must be used. Mixed tires are not permissible and
will affect vehicle performance, safety, and can
affect vehicle warranty.Porsche dealers can recommend the most current
replacement tire options for your vehicle.
Initially, new tires do not have their full traction.
You should therefore drive at moderate speeds
during the first 60 - 120 miles (100 - 200 km).
Tires must always remain on the same side of
the vehicle.
When wheels are removed, the direction of rota-
tion and position of each wheel should be marked.
If new tires are installed only on one axle, a notice-
able change in handling occurs due to the different
tread depth of the other tires. This happens espe-
cially if only rear tires are replaced. However, this
condition disappears as the new tires are broken
in.
fPlease adjust your driving style accordingly.
Installation of new tires should only be done by a
qualified tire technician.
Valves
fUse only plastic valve caps.
fThe rubber valves must be replaced whenever
the tires are changed.
fThe fitting and replacement specifications
must be observed for metal valves.
fOnly use Original Porsche metal valves.
fProtect the valve inserts against soiling with
valve caps.
Soiled valve inserts can cause a gradual loss
of air.
