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

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.

Instruments, On-Board Computer
Check Engine
(Emission Control)The emission control system detects malfunctions
early that could, for example, cause increased
pollutant emissions or consequential damage.
Faults are indicated by a continuously lit or
flashing instrument panel warning light.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a bulb check
and goes out approx. 4 seconds after the engine
starts. If the warning light does not light up, have
the bulb replaced promptly.
The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
fIn order to avoid consequential damage to the
engine or emission control system (e.g.
catalytic converter), have the fault diagnosed
and rectified immediately at the nearest autho-
rized Porsche dealer.If the warning light in the instrument panel lights up
permanently without flashing before and remains
on while driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– the vehicle was refueled while the engine was
running.
fStop immediately at a suitable and secure
place and check tank cap for proper fastening.
If tank cap was fastened correctly, see your
authorized Porsche dealer for service as soon
as possible.
Caution!
If the check engine warning light in the
instrument panel is flashing, serious
catalytic converter damage and power loss
will soon occur.
Prolonged driving with the check engine
warning light on could cause damage to the
emission control system. It also could affect
fuel economy and driveability.
fHave the fault remedied at the nearest authorized Porsche dealer immediately.The central warning light on the instrument panel
lights up if there are warning messages in the
INFO menu.
The messages can be called in the on-board
computer INFO menu:
fPlease see the chapter “INFO WARNING
MESSAGES” on Page 123.
The warning light on the instrument panel lights
up:
– if the handbrake is on,
– if the brake fluid level is low,
– if the brake pads have reached the wear limit,
– if the brake circuit division is defective.
Additionally, a warning is displayed by the on-
board computer.
fPlease see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 148.

1. Vehicle stationary.
2. It is important to ensure that the vehicle is on
a level surface for correct oil level measure-
ment to occur.
3. Engine must be at operating temperature
(at least 140 °F/60 °C oil temperature).
4. Engine must be idling.Initiating oil level measurement
1. Push operating lever forward in order to switch
on the selection field.
2. Select “OIL” with the operating lever.

Instruments, On-Board Computer 6. If the segments are filled in up to the top line,
the oil level has reached the maximum mark.
Under no circumstances add engine oil.7. If only the bottom segment is filled in, the oil
level has reached the minimum mark.
Add engine oil immediately.
8. If the bottom segment flashes, the oil level has
dropped to below the minimum mark.
Add engine oil immediately.
The difference between the minimum and
maximum marks on the segment display is
approx. 1.1 quarts (1.0 liters).
One segment of the display between the minimum
and maximum marks corresponds to a top-up
quantity of approx. 0.32 quarts (0.3 liter).fAdd engine oil if necessary.
Switch off ignition before adding engine oil.
fPlease see the chapter “ENGINE OIL LEVEL”
on Page 160.
fNever add more engine oil than required
to reach the maximum mark.
Failure
A failure of the oil level display is indicated by a
warning message on the on-board computer.
Display “Check oil level”
The on-board computer display “Check oil level” is
an additional reminder to you to check the oil level.
The display depends on the distance travelledand
the operating conditions, and does not indicate
whether or not the oil level is correct.
