Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the "On" position and verifying that the warning
light illuminates.
Brake warning light USA
Brake warning light Canada
If the warning lights in the instrument panel and on-
board computer go on while driving, the brake flu-
id level may be too low, or (if the brake pedal travel
has increased) one of the two brake circuits may
have 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 actuation should be 1-3/16 in. to
1-9/16 in. or 30 to 40 mm.
Whenever the brake pedal travel exceeds this dis-
tance, have the brake system checked.

Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Any obstruction of the brake pedal could
increase 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
nonskid floor mats of the correct size.
Note
In case one of the two brake circuits fails, in-
creased pedal travel is required to bring your
vehicle 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
gear or 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
often.
This could cause the brakes to get hot and not
function properly.
f Please see the chapter "DRIVE-OFF ASSIS-
TANT" on Page 173.
