Maintenance and Car Care Checking the coolant level when a warning
messages is shown on the multi-purpose
display of the instrument panel
Warning!
Danger of serious personal injury or death
from scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
fDo not open the cap of the expansion tank
while the engine is hot.
fAllow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
fKeep coolant out of children's reach.
fAlso, keep coolant away from your pets. They
can be attracted to it should there be a spill, or
to used coolant left in an open container. Coolant can be deadly to pets if consumed.1. Remove cover.
2. If the engine is hot, cover the the expansion
tank cap with a cloth.
Open cap carefully and allow any overpressure
to escape.
Then unscrew cap completely.
3. Read the coolant level.
Top up with coolant if necessary.
Only add a mixture of anti-freeze and water in
equal parts.
Antifreeze in coolant:
50% provides anti-freeze protection down to
-31 °F (-35 °C).
Do not exceed the max-mark.
Note on operation
fIf the coolant level exceeds the max-mark
when the engine is hot, check the coolant level
again when the engine is cold.
4. Screw the cap closed firmly and put on the
cover.
5. Have the cooling system checked by an
authorized Porsche dealer.
Maintenance Notes
If in an emergency pure water has been added, the
mixture ratio must be corrected at an authorized
Porsche dealer.
fMarked loss of coolant indicates leakage in the
cooling system.
The cause should be remedied at an
authorized Porsche dealer immediately.
Radiator fansThe radiator and radiator fans are in the front of
the car.
Warning!
Danger of injury. The fans can start running
as a function of temperature, even with the
engine switched off.
fExercise extreme caution when working in the area of the radiator fans.

Brake-Fluid LevelfUse only new (unused) Original Porsche brake
fluid.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 250.
Warning!
Brake fluid is hazardous to your health, and
may be fatal if swallowed.
Brake fluid also attacks paintwork.
fKeep brake fluid out of children's reach.
fImmediately rinse off spilled brake fluid with
clean water.
fIf brake fluid gets into your eye, immediately
rinse with clean water for a few minutes. Then
see a doctor immediately.
fPlease note all the information on the refill container of the brake fluid.
Checking the brake-fluid levelThe reservoir for the hydraulic braking system is
located in the engine compartment.
1. Rotate the turn-locks 90° anti-clockwise
(arrow) with a screwdriver and remove the
cover.
2. Check brake-fluid level at the transparent
reservoir.
The fluid level should always lie between the
MIN and MAX 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 MIN mark, the braking system may have
developed a leak.
fPlease have the braking system checked
immediately at an authorized Porsche dealer.

Power Steering
Warning!
Risk of accident resulting in serious personal
injury or death. When the engine is stationary
(e.g. when on tow) or the hydraulic system
fails, there is no assistance for steering.
Therefore, substantially more force will have
to be exerted.
fExercise great care when on tow.
fHave the fault remedied at your nearest authorized Porsche dealer.
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the
steering system.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 250.
Checking hydraulic fluidfUse only hydraulic fluid authorized by
Porsche.
fCheck the fluid level with the engine stopped
and cold (engine temperature approx. 68 °F or
20 °C).
1. Remove cover A.2. Open the reservoir cap.
3. The fluid level should lie between the MIN and
MAX marks on the dipstick.
Add hydraulic fluid if necessary.
4. Close cap carefully.
5. Put on cover A.
6. Close engine compartment lid.
Note on operation
fIf the fluid level drops significantly, please have
the cause remedied immediately by an
authorized Porsche dealer.

Maintenance and Car Care
Changing Air CleanerRegular replacement of the filter element is part of
servicing.
fIn dusty conditions, clean the filter element
more frequently and replace if necessary.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 250.Changing Particle FilterThe fresh air passing through the particle filter into
the passenger compartment is virtually free of
dust and pollen.
fIf the outside air is polluted by exhaust fumes,
press the recirculating-air button.
A dirty filter can be the cause of reduced air
throughput.
fHave filter replaced by your authorized
Porsche dealer.
fRegular replacement of the filter is part of
servicing.
Automatic Transmission Fluid The torque converter and the transmission are
lubricated with Automatic Transmission Fluid
(ATF).
fPlease see the chapter “CAPACITIES” on
Page 359.
Do not tow the car or run the engine without ATF
in the transmission. The automatic transmission
may be damaged by even a tiny speck of dirt, only
a clean funnel or spout must be used when adding
AT F.
The ATF and transmission oil has to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
We recommend that you have the ATF and trans-
mission oil changed at your Porsche dealer, who
has the required lubricants and the necessary fil-
ling equipment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.
Manual Transmission OilThe transmission oil has to be checked and chan-
ged at the intervals listed in your Maintenance
Schedule.
fPlease see the chapter “CAPACITIES” on

Maintenance and Car Care
Cleaning AlcantarafDo not use a leather care product to clean
Alcantara.
For regular care it is sufficient to clean the cover
with a soft brush. Heavy abrasion or rubbing when
cleaning causes a permanent change in the
surface.
Cleaning when lightly soiled
fWet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
fWet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in.Cleaning safety beltsfUse mild detergent to clean soiled belts.
fWhen drying, avoid direct sunlight.
fOnly use suitable cleaning agents.
fDo not tint or bleach the belts.
The belt fabric could be weakened, thus affec-
ting safety.
Storing your PorscheIf you intend to store your 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.
fClean 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.
fFill up the fuel tank.
fChange the oil and oil filter, and run the engine
for several minutes.
fIncrease the tire pressure to 58 psi (4 bar). It
is not recommended to lift the vehicle, due to
the possibility of corrosion on shock absorber
piston shafts.The vehicle should be moved
slightly, approximately 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
fCheck and correct antifreeze/cleaning solution
level as necessary.Electrical system
fRemove 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.
fRecharge 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.
fPlease see the chapter “CHARGE STATE” on
Page 320.
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.
fWindows, doors, lids and roof must be closed.
The air vents should be opened.
