Several air bag system components get hot after inflation. Do not

touch them after inflation.

If the air bag has deployed, 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 air bag modules (which include the inflators and

air bags),

• one or more impact and safing sensors and diagnostic monitor (RCM),

• a readiness light and tone

• the electrical wiring which connects the components.

The RCM (restraints control 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 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.
