The Safety Canopy deploys during
significant side crashes or when a certain
likelihood of a rollover event is detected
by the rollover sensor. The Safety Canopy
is mounted to the roof side-rail sheet
metal, behind the headliner, above each
row of seats. In certain sideways crashes
or rollover events, the Safety Canopy will
be activated, regardless of which seats are
occupied. The Safety Canopy inflates
between the side window area and
occupants to further enhance protection
provided in side impact crashes and
rollover events.
The system consists of the following:
•
Safety Canopy curtain airbags above
the trim panels over the front and rear
side windows identified by a label or
wording on the headliner or roof-pillar
trim.
• A flexible headliner which opens above
the side doors to allow air curtain
deployment · Crash sensors and monitoring
system with a readiness
indicator. See Crash Sensors
and Airbag Indicator (page 79). Properly restrain children 12 years old and
under in the rear seats. The Safety Canopy
will not interfere with children restrained
using a properly installed child or booster
seat because it is designed to inflate
downward from the headliner above the
doors along the side window opening.
AIRBAG PRECAUTIONS
WARNING:
Airbags do not inflate
slowly or gently, and the risk of injury
from a deploying airbag is the greatest
close to the trim covering the airbag
module. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
Properly secure
children 12 years old and under in a rear
seating position whenever possible. If
you are unable to properly secure all
children in a rear seating position,
properly secure the largest child on the
front seat. If you must use a forward
facing child restraint on the front seat,
move the seat as far back as possible.
Failure to follow these instructions could
result in personal injury or death. WARNING:
Do not place your arms
on the airbag cover or through the
steering wheel. Failure to follow this
instruction could result in personal injury.
