Driver's air bag
: deploys in front of the
steering wheel; front-passenger front air
bag ; deploys
in front of and above the glove
box.
They are deployed:
R in the event of certain frontal impacts
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R depending on whether the seat belt is being
used
R independently of other air bags in the
vehicle
If the vehicle overturns, the front air bags are
generally not deployed unless the system
detects high vehicle deceleration in a
longitudinal direction.
Your vehicle has an adaptive, two-stage
driver's air bag. In the event of a collision, the
air bag control unit evaluates the vehicle
deceleration. When the first deployment
threshold is reached, the front air bag is filled
with enough propellant gas to reduce the risk
of injuries. The front air bag is fully deployed
if a second deployment threshold is exceeded
within a few milliseconds.
The front air bags will not deploy in impacts
with vehicle deceleration or acceleration
rates which do not exceed the system’s
preset deployment thresholds for vehicle
deceleration or acceleration. You will then be
protected by the fastened seat belt. The front-passenger front air bag will only
deploy if:
R
the front-passenger seat is occupied.
R the 45 indicator

lamp in the center
console is not lit (Y page 37).
R the impact exceeds a preset deployment
threshold.
The front-passenger air bag is automatically
activated and deactivated. Both driver and
passenger should always check whether the
front-passenger air bag is activated or
deactivated.
The deployment of the driver's air bag does
not mean that the front-passenger air bag will
also deploy. If the system recognizes that the
front-passenger seat is empty, the front-
passenger air bag does not deploy even if the
impact fulfills the criteria and the driver's air
bag has deployed.
If the front-passenger seat is recognized as
occupied, the 45 indicator lamp lights
up for approximately six seconds if
R you turn the SmartKey to position 1 or 2 in
the ignition lock.
R the engine is running and then you switch
it off.
This indicates the operational readiness of
the front-passenger air bag.
Note that objects placed on the front-
passenger seat may cause the system to
recognize the seat as occupied. This can
result in the deployment of the front-
passenger air bag if the impact fulfills the
specified criteria. If the 45 indicator
lamp is lit up, the front-passenger air bag is
deactivated and will not deploy should the
situation arise. If indicator lamp 45 is
not lit up, the front-passenger air bag is
activated and will deploy should the situation
arise. G
WARNING
Your vehicle is equipped with air bag
technology which disables the front- 36
