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.
Determining if the system is operational
The SRS uses readiness lights in the instrument cluster and the
passenger air bag on/off switch or a tone to indicate the condition of the
system. Refer to the Air bag readiness section in the Instrument
cluster chapter or Passenger air bag on/off switch section in this
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 lights will either
flash or stay lit.
• The readiness lights 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.
Disposal of air bags and air bag equipped vehicles (including
pretensioners)
See your local dealership or qualified technician. Air bags MUST BE
disposed of by qualified personnel.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal air bag under certain conditions. The driver’s air bag and side air
bag are not part of the front passenger sensing system. The front
passenger sensing system works with sensors that are part of the front
passenger’s seat and safety belt. The sensors are designed to detect the
presence of a properly-seated occupant and determine if the front
passenger’s frontal air bag should be enabled (may inflate) or not.
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to turn off the front passenger’s frontal air bag if:
