Driver's air bag
:
deploys in front of the
steering wheel; front-passenger 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
if the seat belt is fastened
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 adaptive, two-stage front air
bags. 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.
Vehicles with OCS (USA only): front-
passenger front air bag deployment is also
influenced by the passenger's weight
category as identified by the Occupant
Classification System (OCS) (
Y
page 41).
Vehicles with OCS (USA only): the lighter the
passenger side occupant, the higher the
vehicle deceleration rate required for second
stage inflation of the front-passenger front air
bag. In the second stage, the front air bags
are inflated with the maximum amount of
propellant gas available.
In impact situations with deceleration or
acceleration values lower than the vehicle
deceleration or acceleration values preset in
the system, the front air bags are not
deployed. You will then be protected by the
seat belt.
! Vehicles with BabySmart™ (Canada only):
do not place any objects which weigh more
than 20 lb (9 kg) on the front-passenger
seat. This could cause the system to
identify the seat as being occupied. In the
event of an accident, the restraint systems
on the front-passenger side are triggered.
Have restraint systems that have been
triggered replaced.
The front-passenger air bag will only deploy
if:
R
the system, based on the OCS weight
sensor readings, detects that the front-
passenger seat is occupied (USA only).
R
the
45
indicator lamp in the center
console is not lit, USA: (
Y
page 41),
Canada: (
Y
page 46).
R
the impact exceeds a preset deployment
threshold.
