bag ; deploys in front of and above the glove
box.
They are deployed:
in the event of certain frontal impacts
R
if the system determines that air bag
R
deployment can offer additional protection
to that provided by the seat belt
if the seat belt is fastened
R
independently of other air bags in the
R
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. In the first deployment stage,
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 deployment of the front-passenger front
air bag is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) ( Y
The lighter the passenger side occupant, the
higher the vehicle deceleration rate required
(predicted at the start of the impact) 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.
The front air bags are not deployed in
situations where a low impact severity is
predicted. You will then be protected by the
fastened seat belt.

The front-passenger front air bag will only
deploy if:
the system, based on the OCS weight
R
sensor readings, detects that the front-
passenger seat is occupied.
the 45 indicator lamp in the center
R
console is not lit, (
the air bag control unit predicts a high
R
impact severity.
Driver's knee bag
Driver's knee bag : provides additional
protection for the driver against:
knee injuries
R
thigh injuries
R
lower leg injuries
R
Driver's knee bag : deploys below the
steering wheel. During a frontal impact, if the
system determines that air bag deployment
can offer additional protection to that
provided by the seat belt, driver's knee
bag : is deployed along with the driver's air
bag. The driver's knee bag : operates best
in conjunction with a properly positioned and
fastened seat belt.
Side impact air bags

WARNING
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door
trim panels including, for example, the
addition of door speakers.
