Before driving off...
11
Dear Porsche Owner A lot has gone into the manufacture of your
Porsche, including advanced engineering, rigid
quality control and demanding inspections.
These engineering and safety features will be
enhanced by you... the safe driver... – who knows his/her car and all controls,
– who maintains the vehicle properly,
– who uses driving skills wisely and always
drives within her/his own capabilities and the
level of familiarity with the vehicle.
You will find helpful hints in this manual on how to
perform most of the checks listed on the following
pages.
If in doubt, have these checks performed by your
authorized Porsche dealer.
Before driving off... Check the following items first fTurn the engine off before you attempt any
checks or repairs on the vehicle.
fBe sure the tires are inflated correctly.
Check tires for damage and tire wear.
fSee that wheel bolts are properly tightened
and not loose or missing.
fCheck engine oil level, add if necessary.
Make it a habit to have engine oil checked with
every refueling.
fCheck all fluid levels such as windshield
washer and brake fluid levels.
fBe sure the vehicle battery is well charged and
cranks the engine properly.
fCheck all doors and lids for proper operation
and latch them properly.
fCheck, and if necessary replace worn or
cracked wiper blades.
fSee that all windows are clear and
unobstructed.
fCheck air intake slots and area between
luggage compartment lid and windshield.
Ensure that these areas are free of snow and
ice, so the heater and the windshield wipers
work properly. fIf a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
fChild restraint systems will not fit into the
Sports bucket seat.
Do not install a child restraint system in the
Sports bucket seat.
The Sports bucket seat cannot be equipped
with the LATCH system and thus the airbag
system cannot be manually deactivated.
fCheck all exterior and interior lights for opera-
tion and that the lenses are clean.
fCheck the headlights for proper aim, and if
necessary, have them adjusted.
fCheck under the vehicle for leaks.
fBe sure all luggage is stowed securely.
Emergency equipment It is good practice to carry emergency equipment
in your vehicle.
Some of the items you should have are:
window scraper, snow brush, container or bag of
sand or salt, emergency light, small shovel, first-
aid kit, etc.

the separate PCM Owner’s Manual.
Changing the sensitivity of the rain sensor
Sensitivity can be set with switch A in 4 stages:
fAdjust switch A upwards –
high sensitivity.
The setting is confirmed by one wipe of the
windshield.
fAdjust switch A downwards –
low sensitivity.Maintenance note
fPeriodically clean the wiper blades with a
window cleaner, especially after the vehicle
has been washed in a car wash. We recom-
mend Porsche window cleaner. If they are very
dirty (e.g. with insect remains), they can be
cleaned with a sponge or cloth.
If the wiper blades rub or squeak, this may be as
a result of the following:
– If the vehicle is washed in an automatic car
wash, wax residues may be adhering to the
windshield. These wax residues can only be
removed by using a window cleaner concen-
trate.
fPlease see the chapter “WASHER FLUID” on

Wiper Blades Wiper blades that are in perfect condition are vital
for a clear view.
fReplace the wiper blades twice per year
(before and after the cold season) or whenever
wiper performance deteriorates.
Caution!
Risk of damage if the wiper arm accidentally
falls back on to the window.
fAlways hold the wiper arm securely when repla-
cing the wiper blade.
Risk of damage if wiper blades that are
frozen in place are loosened improperly.
fThaw the wiper blades before loosening them.

Decals
Caution!
Risk of damage due to separation of the
decal films when using high-pressure
cleaning equipment or steam cleaners.
fDo not use high-pressure cleaning equipment or steam cleaners to clean decal films.
Washing The best method of protecting your car from the
damaging effects of the environment is frequent
washing and the application of a preservative. The
underside of your vehicle should also be
thoroughly washed for cinders, salt or sanding at
winter’s end.
The longer salt, road dust and industrial dust,
dead insects, bird droppings or substances from
trees (resin, pollen) 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 surface
damage (e.g., scratches) more readily than lighter
colors. Dark colors are also more susceptible to
scratching 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
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.
Warning!
Moisture which gets on to the brakes during
a car wash can reduce braking efficiency or
make the brakes pull unevenly which could
increase the danger of an accident, causing
serious personal injuries or death.
fAfter washing the car, test the brakes and
steering and briefly brake the discs dry.
When doing this, take care not to hamper other
road users behind you (traffic conditions permitting). Automatic car washes
fPlease see the chapter “WIPER BLADES” on
Page 173.
Optional add-on parts or parts which project
beyond 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 (always switch them off to
prevent them wiping unintentionally in intermit-
tent or sensor operation)
– External antennas (always unscrew)
– Rear spoiler
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage)
– High-gloss wheels (to prevent these from
getting scratched, do not clean with the wheel-
cleaning brushes of the car wash).
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.

Engine compartment The engine compartment and the surface of the
engine are treated with a corrosion-inhibitor at the
factory.
If degreasing solvents are used to clean the
engine compartment or the engine is washed
down, the process almost invariably removes the
corrosion-inhibiting coating. It is then absolutely
necessary to have a durable preservative applied
to all surfaces, body seams, joints and assemblies
in the engine compartment. This also applies
when corrosion-inhibitor parts are replaced.
Caution!
Risk of damage to the alternator.
fDo not point the cleaning jet directly at the alternator, or cover the alternator.
Effective corrosion-proofing is particularly impor-
tant 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.
Windows The 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
collect on the insides of the windows. These
deposits are augmented by impurities in the air
which enters the car through the fresh air vents.
fClean all windows regularly, inside and outside,
with Porsche window cleaner.
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
polish and could smear the windows and thus
impair vision.
fRemove dead insects with Porsche insect
remover.
Note
Door windows feature a water-repellent (hydro-
phobic) coating which prevents soiling of the
windows.
This coating is subject to natural wear and can be
renewed.
fConsult an authorized Porsche dealer.
Wiper blades Wiper blades that are in perfect condition are vital
for a clear view.
fReplace the wiper blades twice per year
(before and after the cold season) or whenever
wiper performance deteriorates.
fPeriodically clean the 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.
If the wiper blades rub or squeak, this can be as a
result of the following:
– If the vehicle is washed in an automatic car
wash, residues may adhere to the windshield.
These wax residues can be removed only by
using window cleaner concentrate.
– The wiper blades may be damaged or worn.
