How does the side air bag system work?
The side air bag system consists of
the following:
²An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
²A special seat cover designed to
allow airbag deployment.
²The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
²Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
The fact that the air bags did not inflate in a collision does not mean that
something is wrong with the system. Rather, it means the forces were
not of the type sufficient to cause activation. Side air bags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.

TRACTION CONTROLY
For Traction Controlywarning lights refer toWarning Lightsin the
Instrumentationchapter.
Your vehicle may be equipped with the optional Traction Controly
system. This system helps you maintain the stability and steerability of
your vehicle. It is especially useful on slippery and/or hilly road surfaces.
The system operates by detecting and controlling wheel spin. The system
borrows many of the electronic and mechanical elements already present
in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess rear wheel spin to be detected by the
Traction Controlyportion of the ABS computer. Any excessive wheel
spin is controlled by automatically applying and releasing the rear brakes
in conjunction with engine torque reductions. Engine torque reduction is
realized via the fully electronic spark and fuel injection systems. This
process is very sensitive to driving conditions and very fast acting. The
rear wheels ªsearchº for optimum traction several times a second and
adjustments are made accordingly.
The Traction Controlysystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads.
During Traction Controlyoperation you may hear an electric motor type
of sound coming from the engine compartment and the engine will not
ªrev-upº when you push further on the accelerator. This is normal
system behavior.
If you should become stuck in snow
or ice or on a very slippery road
surface, try switching the Traction
Controlysystem off. This may allow
excess wheel spin to ªdigº the
vehicle out and enable a successful
ªrockingº maneuver.
Traction control switch
The traction control switch is located on the left side of the instrument
panel. The traction control system defaults to ON when the ignition key
is turned from OFF to RUN.
