Pointer to the left – engine cold
f Avoid high engine speeds and heavy engine
loading. Pointer in the middle
– normal operating tem-
perature
The pointer may move up to the red area when en-
gine is heavily loaded and outside temperature is
high, but should return to “normal” when engine
load is reduced.
Warning light “A” If the coolant temperature is too high, the warn-
ing light comes on .
Additionally, a warning is displayed in the on-board
computer.
f Pull off the road, turn off the engine and allow
to cool.
f Check radiator and air passages in front end of
car for obstructions.
f Check coolant level.
If necessary, add coolant and have fault reme-
died at an authorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 187.
Note
To prevent excessive temperatures, the cooling-
air passages must not be restricted by coverings
(e.g. films, “stone guards”). If the
coolant level is too low, the warning light
flashes.
Additionally, a warning is displayed in the on-board
computer.
f Switch engine off and allow to cool.
f Add coolant after the engine has cooled to the
touch.
f Have the cause of the fault remedied at an au-
thorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 187.
Caution!
Risk of engine damage.
f If the warning lights come on even though cool-
ant level is correct, do not continue driving.
f Have the fault remedied at the nearest authorized Porsche dealer.
Engine compartment blower fan In addition, this warning light flashes to indicate a
fault in the engine compartment blower fan .
f Have the cause of the fault remedied at an
authorized Porsche dealer.

Coolant LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 186.
The cooling system is filled at the factory with a
permanent coolant.
It provides year-round protection from corrosion
and freezing down to –31 °F/–35 °C .
f Only use antifreeze authorized by Porsche. Checking coolant level The expansion tank with its filler orifice is located
in the rear luggage comp artment under the serv-
ice flap.
f Check the coolant level regularly.
When the engine is cold and the car is level the
fluid level must lie between the “MIN” and “MAX”
markings.
Topping off coolant
Warning!
Danger of serious personal injury or death
from scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
f Do not open the cap of the expansion tank
while the engine is hot.
f Allow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
f Keep coolant out of children’s reach.
f Also, 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 contai-
ner. Coolant can be deadly to pets if consu-
med.
Risk of damage from overflowing coolant.
f Take care while topping off coolant not to soil the luggage compartment or items of luggage.
1. Switch engine off and let it cool. Please see the chapter “COOLING SYSTEM” on
Page 88. 2. Press catch button on the service flap and
open flap.
3. Cover the expansion tank cap with a thick rag. Open cap slowly and ca refully and allow over-
pressure to escape.
Then unscrew cap completely.
4. Only add a mixture of antifreeze and water in
equal parts, and do not exceed the ”Max.“
mark.
Antifreeze in coolant:
50% gives protection down to –31 °F/–35 °C
60% gives protection down to –58 °F/–50 °C
5. Screw cap firmly on.
6. Close service flap.

Maintenance, Car Care
If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant in
dicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.
Engine-compartment blower,
radiator fan The radiator and radiator fans are in the front of
the car.
The engine-compartment bl ower is mounted in the
engine compartment.
Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment temperature is monitored for
approx. 30 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
may continue to run or start to run.
f Carry out work in these areas only with the en-
gine off, the ignition off, and exercise extreme
caution.
Risk of injury. The radiator fans in the front
end of the car may be operating or
unexpectedly start operating when the
engine is switched on.
f Carry out work in these areas only with the en-gine switched off.
Engine Oil It is important to perform oil changes regularly in
accordance with the intervals specified in the
“Maintenance” booklet.
Engine oil consumption
It is normal for your engine to consume oil.
The rate of oil consumptio n depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil
level at all, even after 600 miles (1,000 km) or
more. This is because the oil is gradually becom-
ing diluted with fuel or moisture, making it appear
that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater.
