Pointer to the left – engine cold
fAvoid 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.
fPull off the road, turn off the engine and allow
to cool.
fCheck radiator and air passages in front end of
car for obstructions.
fCheck coolant level.
If necessary, add coolant and have fault reme-
died at an authorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 207.
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.
fSwitch engine off and allow to cool.
fAdd coolant after the engine has cooled to the
touch.
fHave the cause of the fault remedied at an au-
thorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 207.
Caution!
Risk of engine damage.
fIf the warning lights come on even though cool-
ant level is correct, do not continue driving.
fHave 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.
fHave the cause of the fault remedied at an
authorized Porsche dealer.

Instruments, On-Board Computer, Warnings The oil pressure is controlled as required and
should be at least 3.5 bar at an engine speed of
5000 rpm.
The engine oil pressure varies depending on the
engine speed, engine load and engine tempera-
ture.If oil pressure drops abruptly and a message
is displayed on the on-board computer when
the engine is running on or when driving:
fStop immediately in a suitable place.
fSwitch off the engine.
fCheck whether there is an obvious oil leak on
or under the car.
fIf no oil leak can be detected: With the engine
idling, measure the oil level with the on-board
computer.
fPlease see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 153.
fPlease see the chapter “ENGINE OIL LEVEL”
on Page 208.
fAdd engine oil if necessary.
Caution!
Risk of engine damage.
fDo not continue driving if there is an obvious oil
leak.
fDo not continue driving if the warning lights
come on even though oil level is correct.
fHave the fault remedied at the nearest authorized Porsche dealer.If the battery voltage drops abruptly, a warning
message will be displayed by the on-board compu-
ter.
If the warning is displayed by the on-board
computer while the engine is running or while
driving:
fStop the car in a safe place and stop the
engine.
Possible causes
– Defect in the battery charging system.
– Broken drive belt.
Warning!
Risk of engine damage with resultant loss of
control and accident, leading to serious per-
sonal injury or death.
A broken drive belt means there is no power
assistance to the steering (more effort is re-
quired to steer) and coolant pump function
will stop.
fDo not continue driving.
fHave the fault remedied at the nearest author-ized Porsche dealer.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position
or the PDK selector lever in position P or N.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted
on the engine-compartment lid.
The engine-compartment blower can start or
continue running as a function of temperature,
even with the engine switched off.
Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise ex-
treme caution when working on any part of the
engine while the ignition is on or the engine is
running.
fAlways support your car with safety stands if it
is necessary to work under the car.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty cov-
erage.
fSupplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried in your vehi-
cle.
Please make enquiries before driving abroad.

Coolant LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 206.
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
.
fOnly use antifreeze authorized by Porsche.
Checking coolant level The expansion tank with its filler orifice is in the en-
gine compartment.
fCheck the coolant level regularly through the
transparent expansion tank.
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.
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 contain-er. Coolant can be deadly to pets if consumed.1. Switch engine off and let it cool.
Please see the chapter “COOLING SYSTEM” on
Page 120.
2. Cover the expansion tank cap with a thick rag.
Open cap slowly and carefully and allow over-
pressure to escape.
Then unscrew cap completely.
3. 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
4. Screw cap firmly on.
If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant indicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.
