WARNING: If the Safety
Canopy
system has
deployed, the Safety Canopy
will
not function again unless replaced.
The Safety Canopy
system
(including the A, B, C, and D
pillar trim and headliner) must be
inspected and serviced by an
authorized dealer. If the Safety
Canopy
is not replaced, it will
not function again, which will
increase the risk of injury in a
future collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to the Airbag readiness
section in the Instrument Cluster chapter. Routine maintenance of the
airbag is not required.
Any difficulty with the system is indicated by one or more of the
following:
• The readiness light (same light as for front airbag system) will either
flash or stay lit.
• The readiness light 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 light are repaired.
If any of these things happen, even intermittently, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision or rollover event.
SOS Post-Crash Alert System™
The system automatically flashes the turn signal lamps and sounds the
horn three times at four second intervals in the event of a serious impact
that deploys an airbag (front, side, side curtain or Safety Canopy
) or
the safety belt pretensioners.
