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 op-
erate. However, you will notice an increased pedal
travel when you apply the brakes.Failure of one
brake circuit will cause the stopping distance to in-
crease.
Warning!
Risk of an accident. In the unlikely event of
hydraulic failure of one brake circuit:
fPush 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.
fAfter bringing your vehicle to a complete stop,
avoid driving the vehicle and instead have it
towed to the nearest authorized Porsche deal-er for repair.The warning light in the instrument panel lights up.
A message will be displayed on the multi-purpose
display of the instrument panel if the brake fluid
level is too low, or (if the brake pedal travel has in-
creased) one of the two brake circuits has 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 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 wearYour car has excellent brakes, but they are still
subject to wear. The rate at which they wear de-
pends on how the brakes are used.
fHave the brake system inspected at the inter-
vals recommended in your Maintenance Book-
let.
A warning message will be displayed on the multi-
purpose display of the instrument panel if the
brake pads are worn, excessively.
fDo not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 124.
Brake pads and brake discsWear on the brake pads and brake discs depends
to a great extent on the driving style and the con-
ditions 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 tem-
peratures.
Certain speeds, braking forces and ambient con-
ditions (such as temperature and humidity) there-
fore might cause the brakes to squeal.New brake pads or linings
New brake pads have to be “broken in“, and there-
fore only attain optimal friction when the car has
covered several hundred miles or km.
The slightly reduced braking ability must be com-
pensated for by pressing the brake pedal harder.
This also applies whenever the brake pads and
brake discs are replaced.

Emission ControlThe emission control system detects malfunctions
early that could, for example, cause increased pol-
lutant emissions or consequential damage.
Faults are indicated by the warning light in the in-
strument panel by being continuously lit or flash-
ing.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a lamp check
and goes out approx. 4 seconds after the engine
starts.The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
The warning light in the instrument panel is lit
continuously after the critical range is left.
fIn order to avoid consequential damage to the
engine or emission control system (e.g. cata-
lytic converter) go immediately to the nearest
authorized Porsche dealer to have the fault
diagnosed and rectified.
Caution!
Risk of damage. If the warning light in the in-
strument panel continues flashing even when
you have eased off the accelerator pedal,
the emission control system may overheat.
fStop as soon as possible in a safe place.
Make sure that combustible materials, such as
dry grass or leaves, cannot come into contact
with the hot exhaust system.
fSwitch off the engine.
fContact your nearest authorized Porsche deal-er to have the fault rectified.

monitoring are not present,
– temporarily after changing a wheel,
– has detected too many wheel transmitters,
– there is external interference by other radio
sources, e.g., wireless headphones,
– tire temperatures are too high.
