Parking heater faultsInitial start-up following period of non-
utilization
If you have not used the parking heater for several
weeks, the system may require the parking heater
to be switched on several times before it actually
“starts up”.
fPlease take a break of approximately
5 minutes between each individual switch-on
attempt.
Requirement for initial start-up of the
parking heater:
–Cold engine.Have the parking heater checked by an authorized
Porsche dealer in the following cases:
– If the parking heater fails to “start-up” after the
3rd switch-on attempt.
– In the event of faults in the parking heater, no
function symbol appears on the display – only
the remaining running time is shown.
The display flashes on briefly and then goes
completely dark.
– In the event of a serious accident, the parking
heater switches off automatically for safety
reasons.
The parking heater is not ready for operation.
– If the temperature rises, the overheating
protection switches the parking heater off
automatically. The parking heater is not ready
for operation.
– The parking heater is switched off automati-
cally if the voltage is too low. The parking
heater is temporarily unavailable.

Driving and Driving Safety Brake system warning light
You can check the functionality of the brake sys-
tem warning light by switching the ignition to the
“On” position and verifying that the warning light
illuminates.
The warning light in the instrument panel lights up.
A message will be displayed on the multi-purpose
display of the instrument panel if the brake fluid
level is too low, or (if the brake pedal travel has in-
creased) one of the two brake circuits has failed.
A greater braking pressure will be required, stop-
ping distances will be longer and the braking
behavior will change, particularly in curves.
With correctly adjusted brakes and a correctly
working brake system, the pedal travel to the
point of brake application should be 1-3/16 in. to
1-9/16 in. (30 to 40 mm). Whenever the brake
pedal travel exceeds this value, have the brake
system checked.
Brake pedal
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Any obstruction of the brake pedal could in-
crease the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not
obstructed by a floor mat or any other object.
fSecure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your Porsche dealer will be glad to offer you
floor mats of the correct size including a securing possibility.
Note
In case one of the two brake circuits fails,
increased pedal travel is required to bring your
vehicle to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
fBefore descending a steep grade, reduce
speed and shift the transmission into a lower
gear to control speed.
fDo not “ride the brakes” by resting your foot on
the pedal when not intending to apply brake
pressure.
fDo not hold the pedal down too long or too
often. This could cause the brakes to get hot and not function properly.
