Range of Effectiveness
Even if your vehicle is equipped with an air bag,
the safety belt must be worn at all times be-
cause the air bag system is only actuated by
frontal collisions with an impact of sufficient
severity. See figure for range of effectiveness.
Below the actuation threshold of the air bag sys-
tem, and during types of collisions which do not
cause the actuation of the system, the seat
belts provide the primary protection to the occu-
pants when correctly worn. Therefore, all per-
sons within the vehicle must always wear
safety belts (in many states, state law requires
the use of safety belts). See also chapter
"Safety Belts".
Maintenance / Monitor Lights
The air bag system monitors the operational
readiness of the igniter, sensors, warning lamp,
and control electronics itself.
Any malfunctions which may arise are an-
nounced by the air bag warning light in the in-
strument cluster. Upon activation of the vehicle
ignition circuit, the air bag warning light in the
instrument cluster lights up for approximately 3
seconds and then goes out again, indicating sys-
tem readiness.
In the following cases you should immedi-
ately consult an authorized Porsche dealer
in order to assure the air bag system is
functioning properly:
• Illumination of the air bag warning light during
travel or repeated illumination longer than 5
seconds after ignition circuit is turned on.
• Illumination fails to light up during ignition cir-
cuit activation.
A malfunction in the air bag system will be indi-
cated by the illumination of the air bag warning
light accompanied by the fault message in the
information system display.
In order to ensure long-term functioning, the air
bag system must be inspected by an authorized
Porsche dealer after 4, 8 and 10 years from the
date of manufacture shown on the safety compli-
ance sticker, and then every 2 years.
WARNING
No changes must be made to the wiring or
components of the air bag system. Do not
add any additional coverings or stickers to
the steering wheel or in the area of the pas-
senger side air bag. Doing so may adversely
affect the functioning of the air bag system
or cause harm to the occupants if the air
bag system should deploy.
Do not undertake any wiring for electrical ac-
cessory equipment in the vicinity of the air
bag wiring harness.
Doing so may disable the air bag system.
The actuation of the air bag requires the im-
mediate inspection of the system and re-
placement of some parts of the system. See
your authorized Porsche dealer.
Defects should be repaired immediately. See
your authorized Porsche dealer.
When disposing of a used air bag unit, our
safety instructions must be followed. These
instructions can be obtained
authorized Porsche dealer.
Further information on the air bag system can
be found on stickers in the glove compartment,
at the sun visors, as well as on all air bag com-
ponents.
Important:
If you sell your Porsche, notify the pur-
chaser that the vehicle is equipped with an
air bag, and refer to him or her to the
chapter, "Air Bag System", in the owner's
manual (safety and disposal rules).
For special recommendations on the use of
child restraints, please refer to the chapter
on "Child Restraint Systems."
