Porsche 911 Carrera - Manual (Page 75)

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,
increased pedal travel is required to bring your
vehicle to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
Before descending a steep grade, reduce
speed and shift the transmission into a lower
gear or driving position to control speed.
Do not “ride the brakes” by resting your foot
on the pedal when not intending to apply brake
pressure.
Do not hold the pedal down too long or too
often. This could cause the brakes to get hot
and not function properly.
Brake booster
The brake booster assists braking only when
the engine is running.
When the car is moving while the engine is not
running, or if the brake booster is defective, more
pressure on the brake pedal is required to bring
the car to a stop. If this happens, ABS and PSM will
also not operate.
Moisture or road salt on brakes affects braking.
When the vehicle is driven on salted roads for
extended periods, the brakes should be washed
down thoroughly about every 2 weeks. An auto-
matic carwash facility cannot do this job properly.
Brakes will dry after a few cautious brake applica-
tions.
Warning!
Risk of an accident, resulting in serious
personal injury or death. Driving through
water may reduce traction. Moisture on
brakes from road water, car wash, or coating
of road salt may affect braking efciency.
Cautiously apply brakes to test brakes after
being exposed.
Brake wear
Your car has excellent brakes, but they are still
subject to wear. The rate at which they wear
depends on how the brakes are used.
Have the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
Warning light USA
Warning light Canada
If the warning lights in the instrument panel and
on-board computer stay on when the engine is
running or come on while driving, the brake pads
are worn, excessively.
Do not continue to operate the vehicle. Have
your authorized Porsche dealer inspect or
replace the brake pads.
