Seating and Safety Restraints
The air bag SRS is designed to activate when the vehicle sustains a side
impact 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 collision force was not of the type sufficient to cause
activation. Side air bags are designed to inflate in side-impact collisions,
not frontal, near-frontal, roll over or rear-impact collisions unless the
collision causes sufficient lateral deceleration to cause air bag inflation.
Several air bag system
components get hot after
inflation. Do not touch them after
inflation.
If the side air bag has deployed, the air bag will not function
again. The side air bag system must be inspected and
serviced by a qualified technician. If the air bag is not replaced, the
unrepaired area will increase the risk of injury in a collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the status of the system. Refer to Air bag readiness section in
the instrument cluster chapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
• The readiness light will either
flash or stay lit.
• The readiness light will not
illuminate immediately after
ignition is turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
