The purpose of the air bag is to pro-
vide the vehicle's driver and/or the
front passenger with additional pro-
tection than that offered by the seat
belt alone.
The side air bags are designed to
deploy during certain side-impact
collisions, depending on the crash
severity, angle, speed and point of
impact. However, when side deploy-
ment threshold is satisfied at front-
impact, side air bags may deploy.
The side air bags may deploy on the
side of the impact or on both sides.
The side and/or curtain air bags on
both sides of the vehicle will deploy
if a rollover or possible rollover is
detected.
The side air bags are not designed
to deploy in all side impact or
rollover situations. The side air bag is supplemental to
the driver's and the passenger's
seat belt systems and is not a sub-
stitute for them. Therefore your
seat belts must be worn at all times
while the vehicle is in operation.
For best protection from the side
air bag system and to avoid being
injured by the deploying side air
bag, both front seat occupants
should sit in an upright position
with the seat belt properly fas-
tened. The driver's hands should
be placed on the steering wheel at
the 9:00 and 3:00 positions. The
passenger's arms and hands
should be placed on their laps.
WARNING- Unexpected
deployment
Avoid impact to the side impact
airbag sensor when Engine
Start/Stop button is ON to pre-
vent unexpected deployment of
the side air bag.
WARNING- Deployment
Do not install any accessories
including seat covers, on the
side or near the side air bag as
this may affect the deployment
of the side air bags.
