Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag is inflated, the air bag will not function again
and must be replaced immediately. If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
•
driver and passenger (if equipped) air bag modules (which include the
inflators and air bags),
•
one or more impact and safing sensors,
•
a readiness light and tone
•
and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to the
Air bag readiness
section in the Instrumentation 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 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.
