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. See Instrument Cluster (page
111). 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 you
switch the ignition on.
•The readiness light either flashes or
stays 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 fact that the seatbelt pretensioners
or front 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 and rear inflatable belts
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
or rollover events. Side airbags may
activate in other types of crashes if the
vehicle experiences sufficient sideways
motion or deformation.
•The design of the Safety Canopy is to
inflate in certain side impact crashes
or rollover events. The Safety Canopy
may activate in other types of crashes
if the vehicle experiences sufficient
sideways motion or deformation, or a
certain likelihood of rollover.
AIRBAG DISPOSAL
Contact your authorized dealer as soon as
possible. Airbags must be disposed of by
qualified personnel.
