Brake Fluid LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 196.
f Use only new (unused) Original Porsche
brake fluid.
Warning!
Brake fluid is hazardous to your health, and
may be fatal if swallowed.
Brake fluid also attacks paintwork.
f Keep brake fluid out of children’s reach.
f Take care while topping off brake fluid not to
soil the luggage compartment or items of lug-gage.
Checking the brake fluid levelThe reservoir for the hydraulic braking and clutch
systems is located in the luggage compartment.
1. Open and remove cover flap A.
2. Regularly check the brake-fluid level on the transparent expansion tank through the
window B.
The fluid level should always lie between the
minimum and maximum marks. A slight decrease in the fluid level due to wear and
automatic readjustment of
the disc brakes is
normal.
If, however, the fluid level falls markedly or below
the minimum mark, the br aking system may have
developed a leak.
f Have the brake system checked without delay
at an authorized Porsche dealer.

Maintenance, Car Care

Power Steering
Warning!
Risk of accident resulti ng in serious personal
injury or death.
When the engine is stopped (e.g. when being
towed) or the hydraulic system fails, there is
no assistance for steering.
Therefore, substantially more force will have
to be exerted in order to steer.
f Exercise great care when being towed.
f Have the fault remedied at your nearest autho-rized Porsche dealer.
Note
The flow noise heard at full steering lock is system
related and does not indi cate a defect in the
steering system.
Checking hydraulic fluid f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 196.
The hydraulic fluid reservoir is located in the engi-
ne compartment.
Regular checking of hydraulic fluid is part of
servicing.
Air Filter A dirty air filter not only reduces engine perform-
ance, but can lead to premature engine wear.
Regular filter replacement is part of the routine
maintenance service.
f In dusty conditions, check the filter element
more frequently and replace if necessary.Combination Filter The fresh air passing through the combination fil-
ter into the passenger co mpartment is virtually
free of dust, pollen, and unpleasant odors.
f If the outside air is polluted by exhaust fumes,
press the circulating-air button.
A dirty filter can be the cause of reduced air flow:
f Have filter replaced by your authorized
Porsche dealer.
Regular filter replacement is part of the routine
maintenance service.
Fluids/Oils for Manual
Transmission and Porsche
Doppelkupplung (PDK)The transmission fluids/oils have to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
f Please see the chapter “CAPACITIES” on
Page 281.
Do not tow the car or run the engine without fluid/
oil in the transmission. The transmission may be
damaged by even a tiny speck of dirt, only a clean
funnel or spout must be used when adding fluid/
oil.
We recommend that you have the fluids/oils
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment.
f If you suspect an oil leak in the transmission,
have your authorized Porsche dealer check it
out immediately.

Maintenance, Car Care
219

Danger!
There is a danger of serious personal injury
or death if the airbag system is impaired by
improper cleaning work.
f Do not make any modifications whatsoever on
individual components such as the padded
covers of the steering wheel, passenger side
instrument panel, the front seats and the door
linings.
f Let your authorized Porsche dealer clean these components.
Carpets and floor-mats fUse only a vacuum clea ner or a medium stiff
brush.
f Remove stains and spots with Porsche stain
remover.
To protect carpets, the Porsche range of accesso-
ries includes mats of th e correct size and with the
appropriate fastening.
Warning!
Risk of an accident re sulting in serious per-
sonal injury or death.
f Always check the movement of the pedals be-
fore driving and make sure that they are not ob-
structed by a floor-ma t or any other object. f
Secure the floor-mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicl e - do not install them
loosely in the vehicle.
Your Porsche dealer will be glad to offer you
nonskid floor-mats of the correct size.
Cleaning fabric linings
f Fabric linings on pillars, convertible top liner
and sun blinds, etc. must be cleaned only
using suitable cleaning agents or a suitable dry
foam and a soft brush.
Alcantara fDo not use a leather care product to clean
Alcantara.
For regular care it is su fficient to clean the cover
with a soft brush.
Heavy abrasion or rubbing when cleaning causes
a lasting change in the surface.
Cleaning when lightly soiled
f Wet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
f Wet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in.
Cleaning safety belts

220
Maintenance, Car Care
f
Use mild detergent to clean soiled belts.
f When drying, avoid direct sunlight.
f Only use suitable cleaning agents.
f Do not tint or bleach the belts.
The belt fabric could be weakened, thus affec-
ting safety.
Storing your Porsche If you intend to store yo ur Porsche for a prolonged
period, please consult your authorized Porsche
dealer. The staff will be glad to advise you on the
most suitable and necessary methods.
f Clean your vehicle thoroughly inside and out-
side.
Clean the engine compartment.
The under carriage and chassis components
should be free of dirt and salt deposits.
f Fill up the fuel tank.
f Change the oil and oil filter, and run the engine
for several minutes.
f Increase the tire pressure to 50 psi (3.5 bar).
It is not recommended to lift the vehicle, due to
the possibility of corros ion on shock absorber
piston shafts.
The vehicle should be moved slightly, approxi-
mately every four weeks, to prevent flat spot
on the tires.
Climate control
The air conditioning system should be in good
working condition and fully charged.
Windshield/Headlight washer
f Check and correct antifr eeze/cleaning solution
level as necessary. Electrical system
f
Remove the battery from the vehicle and store
it in a cool dry place, not on a cement floor.
When the battery is disconnected, the
alarm system is deactivated.
f Recharge the battery every 3 months. If the
battery remains in the vehicle with the cables
connected, it is necessary to check, remove
and recharge the battery every 2-3 weeks.
Do not fast charge the battery.
f Please see the chapter “BATTERY” on
Page 249.
Vehicle interior
The interior must be dry, especially in the area of
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs.
(500 grams) each placed on the floor carpets.
Windows, doors and lids must be closed. The air
vents should be opened.

Practical Tips, Emergency Service
227
Danger!
Driving on worn tires can result in loss of con-
trol of the vehicle an d could cause serious
personal injuries or death.
f Do 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.
f Specialized 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 f Avoid damaging tires and wheel rims.
f If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
f Check tires for uneven wear and damage
before driving off.
f Remove imbedded material.
f Replace worn or damaged tires immediately.
f Keep oil, fuel, brake fluid, etc. away from tires.
f Replace missing valve stem caps.
f Keep tires inflated correctly.
f Wash tires when washing the vehicle. Also
clean inner side of wheels.
f Do not use abrasive cleaners when washing
the wheels.
f Check wheel rims for corrosion.
f Remove road salt, if driving in winter.
Tire damage, puncture High-pressure cleaning units can damage the
tires.
f Please see the chapter “HIGH-PRESSURE
CLEANING UNITS, STEAM CLEANERS” on
Page 213.
f Check 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.
f Perform a visual inspection if necessary.

228
Practical Tips, Emergency Service
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.
f Check tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
f After driving off road, examine tires for signs
of damage such as cuts, tears, bulges or for-
eign objects stuck in the tread. Replace a dam-
aged tire if necessary.
f Cross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
f In cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Porsche dealer.
Tire replacements If in doubt, contact your Porsche dealer.
Use only tire makes and types approved 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 make and with the
same specification code (e.g. “N0”, “N1”...)
can be mounted.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Use tires with “ZR” quality standards. There
are currently no standards concerning tire
strength at speeds above 150 mph (240 km/h).
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.
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). 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 especially if only rear tires are re-
placed. However, this condition disappears as the
new tires are broken in.
f
Please adjust your driving style accordingly.
Installation of new tires sh ould only be done by a
qualified tire technician.
Valves
Rubber valve stems must be replaced every time
a tire is replaced.
For metal valves, the installation and replacement
instructions must be observed.
f Use only genuine Porsche metal valves.
f Protect the valve inserts against soiling with
valve caps.
Soiled valve inserts can cause a gradual loss
of air.
f Use only plastic valve caps.
