Porsche.A separate Maintenance Booklet explains how
you can keep your Porsche in top driving condition
by having it serviced regularly.

Safety Belts
Danger!
Always make sure your and your passengers'
safety belts are properly fastened while the
vehicle is in motion.
Failure to follow safety belt warnings may re-
sult in serious personal injury or death.
fFor your and your passengers' protection, use
safety belts at all times while the vehicle is in
motion.
fUse appropriate child restraint systems for all
small children.
Proper wearing of safety belts
fSafety belts must be positioned on the body as
to restrain the upper body and lap from sliding
forward. Improperly positioned safety belts
can cause serious personal injury in case of an
accident.
fThe shoulder belt should always rest on your
upper body. The shoulder belt should never be
worn behind your back or under your arm.
fFor maximum effectiveness, the lap belt
should be worn low across the hips.
fPregnant women should position the belt as
low as possible across the pelvis. Make sure it
is not pressing against the abdomen.
fBelts should not be worn twisted.fDo not wear belts over rigid or breakable ob-
jects in or on your clothing, such as eye glas-
ses, pens, keys, etc. as these may cause inju-
ry.
fSeveral layers of heavy clothing may interfere
with proper positioning of belts.
fBelts must not rub against sharp objects or
damage may occur to the belt.
fTwo occupants should never share the same
belt at the same time.
Care and maintenance
fKeep belt buckles free of any obstruction that
may prevent a secure locking.
fBelts that have been subjected to excessive
stretch forces in an accident must be inspect-
ed or replaced to ensure their continued effec-
tiveness in restraining you.
The same applies to belt tensioner systems
which have been triggered. In addition, the an-
chor points of the belts should be checked.
fIf safety belts do not work properly, see your
authorized Porsche dealer immediately.
fI f t h e b e l t s s h o w d a m a g e t o w e b b i n g , b i n d i n g s ,
buckles or retractors, they should be replaced
to ensure safe operation.
fDo not modify or disassemble the safety belts
in your vehicle.fThe belts must be kept clean or the retractors
may not work properly.
Please observe the chapter “CAR CARE IN-
STRUCTIONS” on Page 265.
fNever bleach or dye safety belts.
fDo not allow safety belts to retract until they
are completely dry after cleaning or this may
cause damage to the belt.

Belt tensionerDepending on the force of a collision, fastened
seat belts are automatically tightened in an acci-
dent.
The belt tensioners are triggered in:
– Front and rear impacts
The belt tensioners are not triggered in:
–Side impacts
– Vehicle overturning
Maintenance note
The belt tensioner system can be triggered only
once; the system must be replaced afterwards.
Work may be performed on the belt tensioner
system only by an authorized Porsche dealer.
Smoke is released when the belt tensioners are
triggered.
This does not indicate a fire in the vehicle.An audio-visual warning system is interconnect-
ed with the driver’s safety belt.
Every time the ignition is turned on, the gong will
sound for about 6 seconds to remind driver and
passenger to buckle up.
In addition, the gong will sound if vehicle speed
exceeds 6 mph (10 km/h.)
The safety belt warning lights in the instrument
panel and on-board computer will go off as soon
as the driver has buckled up.

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.

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 108.
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.
