Controls, Safety, Instruments fDo not add any additional coverings or stickers
to the steering wheel or in the area of the pas-
senger airbag and side airbags. Doing so may
adversely affect the functioning of the airbag
system or cause harm to the occupants if the
airbag system should deploy.
fDo not undertake any wiring for electrical ac-
cessory equipment in the vicinity of the airbag
wiring harnesses. Doing so may disable the air-
bag system or inadvertant inflation.
fIf the warning light comes on, the airbag sys-
tem should be repaired immediately by your
authorized Porsche dealer.
fAlways keep feet in the footwell while driving.
Do not put feet on the dashboard or the seat
area.
Note
Airbag components (e.g. steering wheel, door
trim) may be disassembled only by an authorized
Porsche dealer.
When disposing of a used airbag unit, our safety
instructions must be followed. These instructions
can be obtained at any authorized Porsche dealer.Faults are indicated by a warning light on the ta-
chometer and a message on the instrument
panel’s multi-purpose display.
fIn the following cases you should immedi-
ately consult an authorized Porsche
dealer in order to assure the airbag sys-
tem is functioning properly:
– If the warning light does not light up when the
ignition is switched on or
– If the warning light does not go out once the
engine is running or
– If the warning light appears while driving.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 106.
Airbag maintenanceIn order to ensure long-term functioning, the air-
bag system must be inspected by an authorized
Porsche dealer at the intervals recommended in
your Maintenance Booklet.
Important information
If you sell your Porsche, notify the purchaser that
the vehicle is equipped with airbags, and refer
them to the chapter, “Airbag Systems“, in the
owner's manual (safety and disposal rules).
Further information on the airbag system can be
found on stickers attached to the sun visors, as
well as on all airbag components.
For special recommendations on the use of child
restraints:
fPlease observe the chapter “CHILD RES-
TRAINT SYSTEMS” on Page 47.DisposalfNon-ignited gas alternators, or whole vehicles
or subassemblies with airbag units, must not
be disposed of as “normal” scrap or waste or
put into any other form of end storage.
Your authorized Porsche dealer will be able to
give you details about disposal.

Parking BrakeThe parking brake acts on the rear wheels and
serves to secure the car while parked.
fUse the parking brake only after the vehicle
has come to a full stop.
Applying the parking brakefPress down firmly on the foot pedal.
The warning light in the instrument panel lights
up.
A message will be displayed on the multi-pur-
pose display of the instrument panel if the
parking brake is not released before moving
off.
If the brake is not fully set, the vehicle may roll
without control.
fMove the selector lever to “P“.
fBefore exiting the vehicle, make sure that the
parking brake is fully applied and the vehicle is
not moving at all.
Danger!
Risk of serious personal injury or death. A
partially engaged parking brake may allow
the vehicle to roll, causing serious personal
injury or death to any person in its path.
fEngage the parking brake fully.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 106.fPress on the footbrake and pull handle A of the
parking brake.
The warning light and the message disappear.

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. or 30 to 40 mm. Whenever the brake
pedal travel exceeds this value, have the brake
system checked.
Brake pedal
Warning!
Risk of an accident.
Any obstruction of the brake pedal could in-
crease the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not ob-
structed by a floor mat or any other object.
fSecure 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 secur-ing possibility.
Note
In case one of the two brake circuits fails, in-
creased pedal travel is required to bring your vehi-
cle to a full stop.

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.
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 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 106.
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.
