WARNING MESSAGES” on page 152.
BrakesfMake it a habit to chec k the operation of your
brakes before driving.
Keep in mind that the braking distance increases
very rapidly as the speed increases. At 60 mph
(100 km/h), for example, it is not twice but four
times longer than 30 mph (50 km/h). Tire traction
is also less effective when the roads are wet or
slippery.
f Therefore, always maintain a safe distance
from the car in front of you.Vehicles without Porsche Ceramic
Composite Brake (PCCB)Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your car is parked for an extended
period. The brakes will tend to “rub” as a result.
The nature, extent and effects of corrosion
depend on the amount of time the vehicle was
parked, whether road salt or grit was spread and
whether grease-dissolving agents were used in
car washes.
If the braking comfort is noticeably impaired, we
recommend having the brake system checked by
experts at an authorized Porsche dealer.
Brake system functionYour Porsche is equipped with a power assisted
hydraulic dual circuit brake system with disc
brakes at the front and rear.
Both circuits function independently. One brake
circuit operates the front left and rear right wheel
and the other operates the front right and rear left
wheel.
If one brake circuit has failed, the other will still
operate. However, you will notice an increased
pedal travel when you apply the brakes. Failure of
one brake circuit will cause the stopping distance
to increase.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
In the unlikely event of hydraulic failure of
one brake circuit:
f Push the brake pedal down firmly and hold it in
that position. A mechanical linkage activates
the second circuit, and you will be able to bring
the vehicle to a stop.
f After bringing your vehicle to a complete stop,
avoid driving the vehicle and instead have it
towed to the nearest authorized Porsche dealer for repair.

Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the “On” position (position 1) and verifying that the
warning light illuminates.
The warning light in the instrument panel lights up.
A message will be displayed on the multi-function
display of the instrument panel if the brake fluid
level is too low, or (if the brake pedal travel has
increased) one of the two brake circuits has failed.
A greater braking pressure will be required,
stopping 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
personal 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
obstructed 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 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:
f Before descending a steep grade, reduce
speed and shift the tran smission 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 overheat and not function properly.
