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 trav-
el 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 approximately
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.

Controls, Instruments
Brake booster warning
The brake booster is monitored, in addition to the
brake fluid level.
If the brake fluid warning lamp lights up after
starting the engine, wait to drive until the required
pressure for the brake booster is established and
the warning light goes out.
If the brake fluid warning lamp in the instrument
panel does not go out, there could be a defect in
the brake booster.
Warning!
Risk of accident due to altered braking
behavior.
f Adjust your speed accordingly for longer
braking distances, higher required pedal
pressures, and altered braking behavior.
f Drive carefully to an authorized Porsche deal-
er. The brake system should be repaired im-
mediatlely.
Brake pedal
Warning!
Risk of an accident.
Any obstruction of the brake pedal could
increase the stopping distance.
f Always check the movement of the brake ped-
al before driving and make sure that it is not
obstructed by a floor mat or any other object.
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 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.
