Your vehicle has a collection of crash and
occupant sensors which provide information
to the restraints control module which
deploys (activates) the front safety belt
pretensioners, driver airbag, passenger
airbag, knee airbag(s), seat mounted side
airbags, and the Safety Canopy. Based on
the type of accident (frontal impact, side
impact or rollover) 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. A
warning indicator light in the instrument
cluster indicates the readiness of the safety
system. If this warning indicator light is not
functioning and there is another fault within
the system, the message cluster may display
an airbag failure warning. See Information
Displays (page 109). You will hear five tones
that repeat periodically until you repair the
problem, the warning indicator light or both.
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 will not illuminate
immediately after the ignition is turned
on.
• The readiness light will either flash or
stay lit.
• A series of five beeps will be heard. The
tone pattern will repeat periodically until
the problem, the light or both are
repaired.
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 safety belt pretensioners and the airbag
supplemental restraint system is designed
to activate when your 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 safety belt 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 (for
example, 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 safety belt pretensioners are
designed to activate in frontal,
near-frontal, side and rollover crashes.
• The design of the side airbags is to inflate
in certain side crashes. Side airbags may
activate in other types of crashes if the
vehicle experiences sufficient sideways
motion or deformation.
