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 en-
gine rpm.
A speed limiter prevents the engine from being
overrevved during acceleration. Before reaching
this area, the next higher gear should be select-
ed.
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 sig-
nals.
Indicator light Lights when high beam or headlight flasher is
switched on.
The indicator light goes out when the high beams
are switched off.

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

If necessary, add coolant and have fault reme-
died at an authorized Porsche dealer.
Please observe the chapter “COOLANT LEVEL”
on Page 179.
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.

The warning light in the instrument panel comes
on when the ignition is first turned on and remains
on briefly as a bulb check. If the light does not
come on, have the bulb replaced promptly.
If the warning lights in the instrument panel and on-
board computer come on and remain on while
driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– refuelling with engine running.
Although the vehicle is usually driveable and will
not require towing, see your dealer for service as
soon as possible.
Caution!
If the Check engine light in the instrument
panel is flashing, severe catalytic converter
damage and power loss will soon occur.
Prolonged driving with the Check engine light
on could cause damage to the emission con-
trol system. It also could affect fuel economy
and driveability.

lights up if there are warning messages in the
INFO menu.
The messages can be called in the on-board
computer INFO menu:
fPlease observe the chapter “INFO WARNING

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.
