How does the Safety Canopysystem work?
The design and development of the
Safety Canopy
system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy
).
The Safety Canopy
system
consists of the following:
•An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one each side of the vehicle).
•A headliner that will flex to open
above the side doors to allow Safety Canopy
deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two side crash sensors mounted at the base of the B-pillar (one on
each side).
•Two side crash sensors located at the c-pillar behind the rear doors
(one on each side).
•Roll over sensor in the restraints control module (RCM).
The Safety Canopy
system, in combination with seat belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats (if equipped). 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 openings.
The Safety Canopy
system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopy
inflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.
Seating and Safety Restraints
126

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
system will be
activated, regardless of which seats are occupied. The Safety Canopy
is
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
system did not activate in a collision
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
system has deployed,the Safety
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
is not replaced, the
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 theAir bag readiness
section in theInstrument Clusterchapter. Routine maintenance of the
air bag is not required.

If the engine fails to start using the preceding instructions (flexible
fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant which aids in starting
and heater/defroster performance. Use of an engine block heater is
strongly recommended if you live in a region where temperatures reach
-23°C (-10°F) or below. For best results, plug the heater in at least
three hours before starting the vehicle. The heater can be plugged in the
night before starting the vehicle.
To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
