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 weight sensing for
the passenger's seat in accordance with
U.S. Federal/Canadian 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 actuated
by frontal collisions with an impact of sufficient se-
verity.
Below the deployment threshold of the airbag
system, 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 42.
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 above the doors
in the roof area.
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, infla-
ting airbags can result in serious personal in-
jury or death.
Improper handling of weight sensing can
unintentionally impair switching the
passenger'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.
The storage compartment must be closed
while driving.
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
passenger airbag, side airbags and head
airbags. Doing so may adversely affect the
functioning of the airbag system or cause
harm to the occupants if the airbag system
should deploy.
Do not use protective seat covers.
fDo not modify the seat coverings. Do not
attach 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 passenger'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
airbag system or cause inadvertent inflation.
fIf the warning light comes on, the airbag
system should be repaired immediately by
your authorized Porsche dealer.

Seats, Mirrors and Steering Wheel 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
moving.
fUsing accessories not approved by Porsche
can cause the weight sensing to be impaired.
fDo not squeeze objects, such as the fire
extinguisher, or first aid kit under the seat.
fOnly have seats removed and installed by an
authorized Porsche dealer so that weight
sensing 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.
fWhen 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
collision 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
pressure 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 would provide no be-
nefit, such as a rear impact against your vehicle.
Other accidents where the airbags are designed
not to deploy are those where the risk of injury
from the airbag deployment could exceed any pro-
tective benefits, such as in low speed accidents or higher speed accidents where the vehicle decele-
rates over a longer time. Since airbag deployment
does not occur in all accidents, this further em-
phasizes the need for you and your passengers 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
tentioner are triggered.
Precondition for activating the restraint systems:
fIgnition is switched on.
Advanced AirbagYour vehicle is equipped with weight sensing for
the passenger's seat in accordance with
U.S. Federal/Canadian Motor Vehicle Safety
Standard 208.
Depending on the weight acting on the
passenger's seat, the passenger's airbag will
automatically be switched on and off.
Depending on the angle and force of impact, the
passenger's airbag which is switched-on will be
triggered during a collision.
Precondition for switching the passenger's airbag
on and off, depending on weight:
fIgnition is switched on.

Seat adjustment for the passenger's seat
Danger!
Safety belts only offer protection when the
backrest is upright and the belts are properly
positioned on the body. Improperly positio-
ned safety belts can cause serious personal
injury or death in an accident.
fDo not operate the car with the driver or pas-senger backrests excessively reclined.
If the seat is in an extreme position (e.g., the back-
rest is in contact with the rear seat bench), the
backrest can warp. Warping of the backrest can
lead to malfunctions.
fCorrect the seat adjustment.
The seat is not jammed and is self-supporting.
The backrest is in the upright position.
fDo not transport a load and objects in the rear
footwell or under the passenger's seat.
If the load or objects are under the seat, they
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
support 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
moving.
If the passenger's seat is warped significantly, a
message is displayed in the multi-purpose display
in the instrument panel:
fCorrect the seat adjustment.
fPlease see the chapter “OVERVIEW OF
WARNING MESSAGES” on Page 149.
Vehicle modifications to accommodate
persons with disabilitiesBecause modifications to your vehicle could
compromise your advanced airbag system,
please call 1-800-PORSCHE prior to having your
vehicle modified.
Automatic deactivation of the passenger
airbags
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
airbag in an accident, Porsche strongly
recommends:
fUnder all normal circumstances, the child seat
must be placed in the rear.
Do not use a child restraint system in the front passenger seat.
Before transporting a child on the passenger seat:
fPlease see the chapter “CHILD RESTRAINT
SYSTEMS” on Page 49.
– When a child weighing up to 29 lbs (13 kg)
is seated in the child restraint system, the front
airbag is automatically deactivated on the pas-
senger side.
– When an adult is seated in the front seat the
front airbag remains active on the passenger‘s
side.

Faults are indicated by a warning light on the
tachometer.
fIn the following cases you should immedi-
ately consult an authorized Porsche
dealer in order to assure the airbag
system 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.
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 see the chapter “CHILD RESTRAINT
SYSTEMS” on Page 49.
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.
fPorsche recommends the use of L.A.T.C.H.
(Lower Anchorage and Tether for Children)
equipped Porsche child seat.
Use only child restraint systems with the LATCH-
system recommended by Porsche. These sys-
tems have been tested and adjusted to the interior
of your Porsche and the appropriate child weight
groups. Other systems have not been tested and
could entail an increased risk of injury.
You can obtain child seats that are LATCH
compatible at your authorized Porsche dealer.
fAlways observe the separate installation
instructions for your child seat.
The use of infant or child restraints is required by
law in all 50 US states and the Canadian provin-
ces. The child restraint system should be one that
complies with U.S. Federal/Canadian Motor Vehic-
le Safety Standards 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 Anchorage and Tether for Children, also
known as ISOFIX) to the LATCH anchorages.
A statement by the seat manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the
instruction manual provided with the restraint.

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 neither 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.
– Choose a child restraint system according to
the weight of the child.
– Child restraint systems that are damaged or
have been heavily stressed in an accident must
be replaced immediately.
– Children could be endangered in a crash if their
child restraints are not properly secured in the
vehicle.
– Do not affix objects to child restraint systems
or cover them with other materials.
fFor maximum safety and protection, do not
use a child restraint system in the front
passenger seat.
Direction of installation for child restraint
systemsAccording to accident statistics, children are safer
when properly restrained in the rear seating posi-
tions than in the front seating positions.
Under all normal circumstances, the child seat
must be placed in the rear.
fDo not use a child restraint system in the front
passenger seat.
Children up to 29 lbs (13 kg)
Children of this weight must be transported in a re-
straint system which is fitted facing backwards.
Children between 20 and 40 lbs (9 and
18 kg)
Children of this weight are transported in child
restraint systems facing forward.
Children between 33 and 55 lbs (15 and
25 kg)
Children of this weight are transported in child
restraint systems facing forward.
Children between 49 and 79 lbs (22 and
36 kg)
Children of this weight are transported in child
restraint systems facing forward.
Using child restraint systems in the front
passenger 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
airbag in an accident, Porsche strongly
recommends:
fUnder all normal circumstances, the child seat
must be placed in the rear.
Do not use a child restraint system in the front passenger seat.
However, there may be serious situations where it
might be necessary to place a child in the front
seat so that he/she can be kept under direct
observation to prevent an immediate risk to the
child (for example, while driving to the doctor or
hospital). The following instructions are provided
to you solely for that purpose.
fSeek appropriate advice from your authorized
Porsche dealer about the possible installation
of a Porsche child restraint system.
fIf a child restraint system must be fastened to
the passenger's seat, adjust the passenger's
seat as far away from the airbag as possible.
