seat belt.
Aproperly fastened seat belti s also
needed to provide the best possible
protection if the vehicle rolls over.
Air bags are not a substitute for seat belts.
Always wear your seat belt, regardless of
whether or not your vehicle is equipped with
air bags.
It is important for your safety and that of your
passengers to have deployed air bags
replaced and to have any malfunctioning air
bags repaired. This will help to make sure the
air bags will continue to provide supplemental
crash protection for occupants.
Front air bags !
Make sure that there are no objects
exerting force on the front-passenger seat.
This could cause the system to identify the
seat as being occupied, and in the event of
an accident, the restraint systems on the
front-passenger side might be triggered.
Have triggered restraint systems replaced. 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.
The front air bags increase protection for the
driver's and front-passenger's head and
chest.
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. If the system detects
high vehicle deceleration in alongitudinal
direction, the front air bags are deployed.
Front-passenger air bag ;is only activated
if the system determines that the front-
passenger seat is occupied. The 4
PASSENGER AIRBAG OFF indicator lamp on
the center console does not light up
(Y page 50).
When a child restraint system is installed on
the front-passenger seat and the 4
PASSENGER AIRBAG OFF indicator lamp in
the center console does not light up:
R a child restraint system without a
transponder for the air bag deactivation
system is installed or
R a child restraint system with a transponder
has not been installed properly.
Your vehicle has adaptive, two-stage front air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
event of a collision. In the first deployment
stage, the front air bag is filled with part of the
total available propellant gas, thereby
reducing the risk of injury. If the air bag
control unit recognizes within a few
milliseconds that the vehicle is being braked
or accelerated faster than originally
predicted, the front air bag is filled with the
maximum amount of propellant gas available.
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. Occupant safety
