Danger!
To provide optimal occupant protection, air-
bags must inflate at very high speed. If you
are not wearing your safety belt or are too
close to the airbag when it is deployed, inflat-
ing airbags can result in serious personal in-
jury or death.
Improper handling of weight sensing can un-
intentionally impair switching the passen-
ger's airbag off and on.
fMake sure there are no people, animals or ob-
jects between the driver or passenger and the
area into which the airbag inflates.
fSit back as far from the dashboard or steering
wheel as is practical, while still maintaining full
vehicle control.
fAlways hold the steering wheel by the outer
rim. Never rest your hands on the airbag panel.
fAlways fasten seat belts because triggering
of the airbag system depends on the force and
angle of impact.
fDo not transport heavy objects on or in front of
the passenger seat. These could impair the
function of the airbag, the seat belts, and
weight sensing.
fDo not hang objects (e.g., jackets, coats, coat
hangers) over the backrest.fAlways keep the lid of the door storage com-
partment closed. Objects must not protrude
out of the door storage compartment.
fNo changes must be made to the wiring or
components of the airbag system.
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 modify the seat coverings. Do not at-
tach additional cushions, protective coverings,
or pillows to the passenger's seat. Do not affix
things to the passenger's seat or cover it with
other materials. Do not cover the back of the
backrest. Do not make changes to the passen-
ger's seat and to the seat base frame.
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 cause inadvertent 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. Do not lean against the inside of the door
or outside the window while the vehicle is mov-
ing.fUsing accessories not approved by Porsche
can cause the weight sensing to be impaired.
fDo not squeeze objects, such as the fire extin-
guisher, or first aid kit under the seat.
fOnly have seats removed and installed by an
authorized Porsche dealer so that weight sens-
ing components will not be damaged.
fGive your passenger all of the information in
this chapter.
Note
Airbag components (e.g. steering wheel, seats)
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.

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.

Tire PressurefPlease observe the chapter “TIRES/WHEELS”
on Page 285.
The tire pressure monitoring continuously
monitors tire pressure and tire temperature on all
four wheels and warns the driver when the tire
pressure is too low.
The display as well as the settings for tire
pressure monitoring are done on the multi-
purpose display in the TIRE PRESSURE menu.
However the tire pressure must be set manually
on the wheel.
The tire pressures to be monitored for tire type
are permanently set in the tire pressure
monitoring and cannot be changed.
The driver is solely responsible for filling the tires
correctly and for selecting in the multi-purpose dis-
play.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure in-
creases increases risk of a tire failure and re-
sulting loss of control. Furthermore, low tire
pressure increases rate of wear of the affect-
ed tires.
Despite the advantages offered by the tire
pressure monitoring, it is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination of the tire
pressure monitoring low tire pressure mes-
sage.
fWhen a flat tire has been displayed, immediate-
ly stop in a suitable place and check the tires
for damage. If necessary remedy the damages
with tire sealant.
fDo not by any means continue to drive with
leaking tires.
fDefective tires must be immediately replaced
by a specialist repair shop.
Tire repairs are not permissible under any
circumstances.
fSealing the tire with the tire sealant is only an
emergency repair, so you can drive to the next
repair shop. The maximum permitted speed is
50 mph (80 km/h).fDo not drive with tires whose tire pressure
drops again in a short period of time. In cases
of doubt, have tires checked by a specialist re-
pair shop.
fIf the tire pressure monitoring is defective
(e.g., defective wheel transmitter), contact a
specialist workshop immediately and have the
damages repaired.
The tire pressure will not be monitored by a de-
fective tire pressure monitoring.
fTires lose air over time without a tire defect be-
ing present. A tire pressure warning will then
appear in the multi-purpose display. Correct
the tire pressure at the next opportunity.
fThe tire pressure monitoring gives a warning
about tire damages due to insufficient tire
pressure as well as about a gradual loss of
pressure due to foreign objects.
The tire pressure monitoring cannot warn you
about tire damages occurring suddenly (e.g.,
flat tire due to sudden external effects).
fBefore fitting tires approved by Porsche which
are not stored in the on-board computer, the
missing information should be supplemented
in the on-board computer.
