HOW DOES THE SAFETY CANOPY™
WORK WARNING:
Do not place objects or
mount equipment on or near the headliner
at the siderail that may come into contact
with a deploying curtain airbag. Failure to
follow these instructions may increase the
risk of personal injury in the event of a
crash. WARNING:
Do not lean your head
on the door. The curtain airbag could injure
you as it deploys from the headliner. WARNING:
To reduce risk of injury,
do not obstruct or place objects in the
deployment path of the airbag. 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 71).
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.
