Safety Belts
Warning!
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 or death 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 glass-
es, 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 anchor points of the belts
should be checked.
fIf safety belts do not work properly, see your
authorized Porsche dealer immediately.
fIf the belts show damage to webbing, bindings,
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 see the chapter “CAR CARE INSTRUC-
TIONS” on Page 224.
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 tensioner Depending on the force of an impact, fastened
front seat safety belts are tightened in an acci-
dent.
The belt tensioners are triggered in:
– Front, side and rear impacts of sufficient
severity.
– For the Cabriolet, in cases of vehicle rollover.
Note
The belt-tensioner system can be triggered only
once; the system must be replaced afterward.
If there is a fault in the belt-tensioner system, the
airbag warning light lights up.
Work may be performed on the belt-tensioner sys-
tem only by an authorized Porsche dealer.
Smoke is released when the belt tensioners are
triggered. This does not indicate a fire in the
vehicle.

42
Operation, Safety 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 for approx. 90 sec-
onds if vehicle speed exceeds 15 mph/24 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.
Inertia reel retractor The combination lap/shoulder belt with inertia reel
locking mechanism adjusts automatically to your
size and movements as long as the pull on the belt
is slow.
Rapid deceleration during hard braking or a colli-
sion locks the belt. The belt will also lock when you
drive up or down a steep hill or in a sharp curve,
otherwise, the shoulder belt will not inhibit your
upper body movement.
Fastening the safety beltfAssume a comfortable sitting position.
fPlease see the chapter “SEAT POSITION” on
Page 30.
fThe shoulder belt should always rest on your
upper body. The shoulder belt should never be
worn behind your back or under your arm.
fGrasp belt and pull the belt in a continuous
slow motion across your chest and lap.
fInsert belt tongue into buckle on inboard side
of seat. Push down until it securely locks with
an audible click. Pull the belt to check.
fPull shoulder section to make sure belt fits
snugly across the pelvis.
fBelts should fit snugly across the pelvis and
chest. Make sure there is no slack in the belt. Releasing the safety beltfPush in release button (arrow) on buckle. Belt
tongue will spring out of buckle.
fTo release a latched belt, lean back to take the
body pressure off the belt.

Cleaning the safety beltsIf it becomes necessary to clean the belts, you
can use any mild washing agent. Allow the belts to
dry prior to retracting, but avoid direct sunlight.
fOnly use suitable cleaners. If unsuitable
cleaners are used or any attempt is made to
dye or bleach the belts, the webbing may be
weakened and thus constitute a safety risk.

Operation, Safety
Airbag SystemsThe airbags in combination with the safety belts
make up a safety system which offers the driver
and the passenger the greatest known protection
from injuries in case of accident.
Your vehicle is equipped with a weight sensing sys-
tem for the front passenger's seat in accordance
with U.S. Federal Motor Vehicle Safety Standard
208.
Even if your vehicle is equipped with airbags, the
safety belts must be worn at all times,
because the front airbag system is only deployed
by frontal collisions with an impact of sufficient se-
verity.
Below the deployment threshold of the airbag sys-
tem, and during types of collisions which do not
cause the actuation of the system, the safety belts
provide the primary protection to the occupants
when correctly worn.
Therefore, all persons within the vehicle
must wear safety belts at all times (in many
states, state law requires the use of safety belts).
fPlease see the chapter “SAFETY BELTS” on
Page 41.
The front airbags are located under the padded
steering wheel panel on the driver’s side and, on
the passenger's side, in the dashboard.
The side airbags for the front seats are installed
on the side in the seat backrests.
The head airbags are installed in the door linings.
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.
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’s 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 may 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’s airbag, side airbags and head air-
bags. Doing so may adversely affect the func-
tioning of the airbag system or cause harm to
the occupants if the airbag system should de-
ploy.
Do not use protective seat covers.
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.

Operation, Safety
45
fUsing accessories not approved by Porsche
can cause the weight sensing system to be im-
paired.
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, door lin-
ing, seats) may be disassembled only by an autho-
rized 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.
Function of the airbag systemAirbags are a supplemental safety system. Your
primary protection comes from your safety belts.
The front airbags are triggered during a frontal col-
lision of sufficient force and direction.
In the event of a side impact of corresponding
force, the side airbag on the impact side is
triggered.
The inflation process generates the amount of gas
required to fill the airbags at the necessary pres-
sure in fractions of a second.Airbags help to protect the head and upper body,
while simultaneously damping the motion of the
driver and passenger in the impact direction in the
event of a frontal impact or side impact.
In order to help provide protection in severe colli-
sions which can cause death and serious injury,
airbags must inflate extremely rapidly. Such high
speed inflation has a negative but unavoidable
side effect, which is that it can and does cause in-
juries, including facial and arm abrasions, bruising
and broken bones. You can help minimize such in-
juries by always wearing your safety belts.
There are many types of accidents in which
airbags are not expected to deploy. These include
accidents where the airbags whould provide no
benefit, such as a rear impact against your vehi-
cle. Other accidents where the airbags are de-
signed not to deploy are those where the risk of
injury from the airbag deployment could exeed any
protective benefits, such as in low speed acci-
dents or higher speed accidents where the vehicle
decelerates over a longer time. Since airbag de-
ployment does not occur in all accidents, this fur-
ther emphasizes the need for you and your pas-
sengers to always wear safety belts.
Your vehicle is equipped with a crash sensing and
diagnostic module. This module will record the
use of the seat belt restraint system by the driver
and front passenger when the airbags and/or belt
tensioner work.
Advanced AirbagYour vehicle is equipped with a weight sensing sys-
tem for the passenger's seat in accordance with
U.S. Federal Motor Vehicle Safety Standard 208.
Depending on the weight acting on the front pas-
senger's seat, the front passenger's airbag will au-
tomatically be switched on and off.
Depending on the angle and force of impact, the
front passenger's airbag which is activated will be
triggered during a collision.
Precondition for switching the front passenger's
airbag on and off, depending on weight:
– Vehicles equipped with key-operated airbag
deactivation device:
Switch position AUTO.
– Ignition key is inserted.
Improper handling of the weight sensing
system can unintentionally impair switching
the passenger's airbag off and on.

46
Operation, Safety Seat adjustment for the front passenger's
seat Danger!
Safety belts only offer protection when the
backrest is upright and the belts are properly
positioned on the body. Improperly posi-
tioned safety belts can cause serious person-
al injury or death in an accident.
fDo not operate the car with the driver or
passenger backrests excessively reclined.
fPorsche recommends the use of L.A.T.C.H.

Do not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be equipped with the LATCH system.
If the seat is in an extreme position (e.g., the back-
rest is in contact with the rear seat), the backrest
can warp. Warping of the backrest can lead to mal-
functions.
fCorrect the seat adjustment.
Ensure that the seat is not jammed and is self-
supporting.
Ensure that the backrest is in the upright posi-
tion.
fDo not transport a load and objects in the rear
footwell and under the passenger's seat.
If the load or objects are under the seat, it can
cause malfunctions.If the weight on the passenger's seat is reduced
significantly, e.g., by supporting weight on the
armrest, the passenger's airbag can be switched
off.
fSelect an upright seat position, and do not sup-
port weight on the armrests or lean out of the
window.
Always 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.
