f Using accessories not approved by Porsche
can cause the weight sensing to be impaired.
f Do not squeeze objects, such as the fire
extinguisher, or first aid kit under the seat.
f Only have seats removed and installed by an
authorized Porsche dealer so that weight
sensing components will not be damaged.
f Give 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.
f 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 system
Airbags 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 air-
bags 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:
f Ignition is switched on.
Advanced Airbag
Your 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 passen-
ger's seat, the passenger's airbag will automati-
cally 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:
f Ignition is switched on.
