CRASH SENSORS AND
AIRBAG INDICATOR
WARNING
Modifying or adding equipment to
the front end of your vehicle
(including hood, bumper system,
frame, front end body structure, tow hooks
and hood pins) may affect the
performance of the airbag system,
increasing the risk of injury. Do not modify
or add equipment to the front end of your
vehicle.
Your vehicle has a collection of crash and
occupant sensors which provide
information to the restraints control
module. The restraints control module
deploys (activates) the front seatbelt
pretensioners, driver airbag, passenger
airbag, knee airbag(s), seat mounted side
airbags and the Safety Canopy. Based on
the type of crash, the restraints control
module will deploy the appropriate safety
devices.
The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following:
• The readiness light either flashes or
stays lit.
• A series of five beeps will be heard. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
E67017
• The readiness light will not illuminate
immediately after you switch the
ignition on.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The seatbelt pretensioners and the airbag
supplemental restraint system are
designed to activate when the vehicle
sustains frontal or sideways deceleration
sufficient to cause the restraints control
module to deploy a safety device or when
a certain likelihood of a rollover event is
detected by the rollover sensor.
The fact that the seatbelt pretensioners
or airbags did not activate for both front
seat occupants in a crash does not mean
that something is wrong with the system.
Rather, it means the restraints control
module determined the accident
conditions (crash severity, belt usage)
were not appropriate to activate these
safety devices.
• The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts) unless the crash causes
sufficient frontal deceleration.
• The design of the seatbelt
pretensioners is to activate in frontal,
near-frontal and side crashes and in
rollovers.
• The design of the side airbags is to
inflate in certain side impact crashes.
Side airbags may activate in other
types of crashes if the vehicle
experiences sufficient sideways motion
or deformation.
