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.
Brake wear warning message

Driving and Driving Safety

Warning!
f Do not obstruct the pedal travel with floor mats
or other objects.
The brake booster is ready for operation only
while the engine is running.
If the engine is switched off or there is a defect in
the brake booster, much greater force has to be
applied to the pedal when braking.
f Vehicles with defective brakes must not
be towed and must be transported on a flat
bed.
For information on towing and tow-starting:
f Please see the chapter “TOWING” on
page 316.
In heavy rain, while driving through water or after
leaving a car wash, the braking action may be
delayed and increased pressure may be required.
f For this reason, keep further back from the
vehicle in front and “dry” the brakes by
applying them at interval s. Make sure that the
traffic behind you is not affected. After a long drive over salted or gritted roads,
a coating may form on the brake discs and pads
that significantly reduces
friction and therefore
also braking effect.
f Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your vehicle 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 (not on vehicles with
Porsche Ceramic Composite Brake).
To prevent corrosion of the brake discs,
“brake them dry” before parking the vehicle
(not on vehicles with Porsche Ceramic
Composite Brake).
If braking comfort is no ticeably impaired, we
recommend that you have the brake system
checked by an authorized Porsche dealer. f
To relieve the brake system on downhill
stretches, change down to a lower gear in
good time (engine braking).
If engine braking is insufficient on steep
stretches, operate the footbrake at intervals.
Avoid continuous braking as it overheats the
brakes and reduces the braking effect.
For information on brake fluid and checking the
brake fluid level:
f Please see the chapter “BRAKE FLUID” on
page 258.

ABS Brake System
(Anti-Lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt his driving style and
maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physic s of driving cannot be
overcome, even with ABS.
Risk of accidents due to inappropriate speed
cannot be reduced by ABS.
ABS ensures
– Full steering control
The vehicle remains steerable
– Good driving stability
No skidding due to locked wheels
– Optimum braking distance
Shorter stopping distance in most cases
– Prevention of wheel locking
No flat spots on the tires Function
The decisive advantage of ABS lies in the driving
stability and maneuverability of the vehicle in
hazardous situations.
ABS prevents locking of
the wheels during full
braking, on almost all road surfaces, until just
before the vehicle stops.
ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a “juddering noise”
warn the driver to adapt his driving speed to the
road conditions.
f If full braking is necessary, press the brake
pedal fully during the whole braking operation,
even though the pedal is pulsating. Do not
reduce brake pressure. If the ABS warning light lig
hts up on the instrument
panel while the engine is running, the ABS has
switched off because of a fault.
The warning message “ABS failure” appears on
the multi-function display in the instrument panel.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
In this case, the brake system will operate without
lock prevention, as on vehicles without ABS.
f Adapt your driving style to the changed
braking behavior.
The ABS must be checked by your authorized
Porsche dealer in order to prevent the
occurrence of further faults with unpredictable
consequences.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with no n-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off. Warning light USA
