If the airbag has deployed, the airbag will not function again
and must be replaced immediately. If the airbag 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 or a tone to
indicate the condition of the system. Refer to Airbag readiness in the
Instrument Cluster chapter. Routine maintenance of the airbag 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 an authorized dealer immediately. Unless serviced, the system may not
function properly in the event of a collision.
Disposal of airbags and airbag equipped vehicles
(including pretensioners)
See your authorized dealer. Airbags MUST BE disposed of by qualified
personnel.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger's frontal
airbag under certain conditions.
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 airbag should be enabled (may inflate) or
disabled (will not inflate).
