Brake warning light USA
Brake warning light

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 be-
havior 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.

Warning!
Risk of an accident.
Any obstruction of the brake pedal could in-
crease the stopping distance.
f Always check the movement of the brake pedal
before driving and make sure that it is not ob-
structed by a floor mat or any other object.
f Secure 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 secur-
ing possibility.
Note
In case one of the two brake circuits fails, in-
creased pedal travel is required to bring your vehi-
cle to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
f Before descending a steep grade, reduce
speed and shift the transmission into a lower
driving position to control speed.
f Do not "ride the brakes" by resting your foot on
the pedal when not intending to apply brake
pressure.
f Do not hold the pedal down too long or too of-
ten. This could cause the brakes to get hot and
not function properly.
