Driving and Driving Safety
Brake boosterThe 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.
Moisture, road salt or grit on brakes affects
braking.
Brakes will dry after a few cautious brake
applications.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
Driving through water may reduce the
traction. Moisture on brakes from road
water, car wash, or a coating of road salt or
grit may affect braking efficiency.
f Cautiously apply brakes to test brakes after exposure to road water, etc.
Brake wearYour car has excellent brakes, but they are still
subject to wear. The rate at which they wear
depends on how the brakes are used.
f Have the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
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.
A warning message will be displayed on the multi-
function display of the instrument panel if the
brake pads are worn, excessively.
f Do not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
Brake pads and brake discsWear on the brake pads and brake discs depends
to a great extent on the driving style and the
conditions of use and therefore cannot be
expressed in actual miles on the road.
The high-performance brake system is designed
for optimal braking effect at all speeds and
temperatures.
Certain speeds, braking forces and ambient
conditions (e.g. temperature and humidity) can
therefore cause the brakes to “squeal”.
New brake pads or linings
New brake pads have to be “broken in”, and
therefore only attain optimal friction when the car
has covered several hundred miles or km.
The slightly reduced braking ability must be
compensated for by pressing the brake pedal
harder. This applies whenever the brake pads
and/or brake discs are replaced.
