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
objects in or on your clothing, such as eye
glasses, pens, keys, etc. as these may cause
injury.
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 256.
fNever bleach or dye safety belts.

ing and slowing down, when cornering and
when driving uphill.
fInsert the belt tongue into the appropriate
buckle on the inboard side of the seat, until it
locks securely with an audible click.
fMake sure that belts are not trapped or twist-
ed, and that they are not rubbing on sharp edg-
es.
fThe horizontal section of the belt should al-
ways fit snugly across the pelvis. Therefore, af-
ter fastening the belt, always pull the diagonal
part of the belt upwards.
Pregnant women should position the belt as
low as possible across the pelvis, and ensure
that it is not pressing against the abdomen.

Child Restraint SystemsPorsche recommends that all infants and children
be restrained in child restraint systems at all times
while the vehicle is in motion in accordance with
applicable laws.
The use of infant or child restraints is required by
law in all 50 states and the Canadian provinces.
The child restraint system should be one that com-
plies with U.S. Federal/Canadian Motor Vehicle
Safety Standards 213 and should be secured by a
lap belt or lap belt portion of a lap-shoulder belt or
for child seats equipped with the LATCH sytem
(Lower A
nchorage and T
ether for Ch
ildren, also
known as ISOFIX) to the LATCH anchorages.
A statement by the seat manufacturer of compli-
ance with this standard can be found on the in-
struction label on the restraint and in the instruc-
tion manual provided with the restraint.
Danger!
Risk of serious personal injury or death to the
child.
fFollow all child restraint instructions and warnings in this manual.
– When using an infant or child restraint system,
be sure to follow all manufacturer's instruc-
tions on installation and use.
– Infants and small children should never be held
on the lap, nor should they share a safety belt
with another occupant while the vehicle is in
motion.
– Children too big for child restraint systems
should use regular safety belts. A shoulder belt
can be used providing it does not cross the
face or the neck of the child.
– For maximum safety and protection, do not
use a child restraint system in the front passen-
ger seat.
Danger!
The use of a child restraint system in the
front passenger seat can result in serious
personal injury or death to the child from an
airbag deployment.
To reduce risk of injury from an inflating air-
bag in an accident, Porsche strongly recom-
mends:
fDo not use a child restraint system in the front passenger seat.
Rearward facing child restraint system:
fUse only in the rear seat. Must not ever be
used in the front.
Forward facing child restraint system:
fUse only in the rear seat. Must not ever be
used in the front.

48
Controls, Safety, Instruments Use only a child restraint system with the LATCH
system recommended by Porsche.
These systems have been tested and adjusted to
the interior of your Porsche and the appropriate
child age groups. Other systems have not been
tested and could entail an increased risk of injury.
You can obtain child seats that are LATCH-compat-
ible at your authorized Porsche dealer.
fAlways observe the separate installation in-
structions for your child seat.
Installing an LATCH child seat systemMarkings on the right and left for the Isofix child
seat anchorage can be found on the backrests of

Controls, Safety, Instruments
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.
