General instructions for air-conditioning
compressor– Can switch off briefly if engine is under an
extreme load to ensure sufficient engine
cooling.
– Switches off automatically at temperatures
below approx. 37 °F/3 °C and cannot be
switched on, even manually.
– Operates most effectively with windows
closed.
If the car has been in the sun for a long time, it
is a good idea to ventilate the interior briefly
with the windows open.
– Depending on the outside temperature and
humidity, condensation can drip from the
evaporator and form a pool under the vehicle.
This is normal and not a sign of leakage.
– If uncooled air flows out when the lowest
temperature has been set, switch off the air-
conditioning compressor and have the fault
repaired at an authorized Porsche dealer. Air distribution to footwell

ambient brightness by the light sensor in the
tachometer.
In addition, when the car lights are switched on,
the instrument and switch symbol brightness can
be manually adjusted.
Warning!
Risk of loss of control or accident, resulting
in serious personal injury or death.

Tachometer The tachometer shows the engine speed in revolu-
tions per minute (rpm).
The beginning of the red marks at the right end of
the scale indicates the maximum permissible
engine rpm.
A speed limiter prevents the engine from being
overrevved during acceleration. Before reaching
this area, the next higher gear should be
selected.
Shift to the next lower gear when the engine rpm
drops below 1,500 rpm.
Caution!
To avoid severe engine damage.
fAlways observe the engine rpm before down-
shifting to a lower gear, so you do not exceed the maximum engine rpm.
Flashes in synchronism with the turn signals.
Left arrow – left turn signals
Right arrow – right turn signals
fIf the frequency of the display becomes notice-
ably faster, check the operation of the turn
signals.
Lights when high beam or headlight flasher is
switched on.
The indicator light goes out when the high beams
are switched off.
The indicator light flashes in the event of cornering
light failure.In addition to the red zone on the tachometer
scale, the upshift arrow also prompts you to
initiate the gear shift in good time.
fWhen the upshift indicator lights up, change to
next-higher gear.

Temperature gauge (ignition on) USA: Display in °F
Canada: Display in °C
Pointer to the left – engine cold
fAvoid high engine speeds and heavy engine
loading. Pointer in the middle – normal operating tempe-
rature
The pointer may move up to the red area when
engine 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
warning 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
remedied at an authorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 158.
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
authorized Porsche dealer.
Please see the chapter “COOLANT LEVEL” on
Page 158.
Caution!
Risk of engine damage.
fIf the warning lights come on even though
coolant 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.

Level gauge

When the ignition is on the fuel level is displayed.
fPlease see the chapter “CAPACITIES” on
Page 239.
If the vehicle’s inclination changes (e.g. going up
or downhill), minor deviations in the indication may
occur. Note
If a small quantity of fuel is added to a nearly
empty fuel tank, the fuel gauge cannot measure
the added fuel accurately. The „remaining range“
readout will also be incorrect.
Warning light “A” When the engine is running, the warning light
of the level gauge lights up if less than approx.
2.6 U.S. gallons (10
liters) of fuel remains in the
tank.
Additionally, a warning is displayed in the on-board
computer.
fFill up at the next opportunity.
Caution!
To prevent damage to the emission control
system and engine.
fNever drive the tank completely out of fuel.
fAvoid high cornering speeds after the warning lights have come on.
fPlease see the chapter “EMISSION CONTROL
SYSTEM” on Page 168.If the level gauge warning light flashes, there
has been a system fault.
Additionally, a warning is displayed in the on-board
computer.
There will then be no reserve warning.
fTo remedy the fault, go to an authorized
Porsche dealer.

With the engine warmed up and running at a speed
of 3000 rpm, the engine oil pressure should be
approx. 3.5 bar or higher.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:
Measure the oil level using the on-board
computer with the engine idling.
Please see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 143.
fAdd engine oil if necessary.
Please see the chapter “ENGINE OIL LEVEL”
on Page 160.
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
computer.
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
personal injury or death.
A broken drive belt means there is no power
assistance to the steering (more effort is
required to steer) and coolant pump function
will stop.
fDo not continue driving.
fHave the fault remedied at the nearest autho-rized Porsche dealer.
