The Safety Canopy is mounted to the roof side-rail sheet metal, behind
the headliner, above the first and second row seats. In certain lateral
collisions or rollover events, the Safety Canopy
activated, regardless of which seats are occupied. The Safety Canopy
designed to inflate between the side window area and occupants to
further enhance protection provided in side impact collisions and rollover
events.
The fact that the Safety Canopy
does not mean that something is wrong with the system. Rather, it
means the forces were not of the type sufficient to cause activation. The
Safety Canopy is designed to inflate in certain side impact collisions or
rollover events, not in rear impact, frontal or near-frontal collisions,
unless the collision causes sufficient lateral deceleration or rollover
likelihood.
Several Safety Canopy
system components get hot
after inflation. Do not touch them
after inflation.
If the Safety Canopy
Canopy will not function again. The Safety Canopy
system (including the A, B and C pillar trim) must be inspected
and serviced by a qualified technician in accordance with the
vehicle service manual. If the Safety Canopy
unrepaired area will increase the risk of injury in a 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 Air bag readiness
section in the Instrument Cluster chapter. Routine maintenance of the
air bag is not required.
