considerable force, there is the risk of death or
serious injuries such as fractures, facial and eye
injuries or internal injuries, particularly to occupants
who are not properly restrained or are otherwise out
of position at the time of air bag deployment. Thus,
it is extremely important that occupants be properly
restrained as far away from the air bag module as
possible while maintaining vehicle control.
Several air bag system components get hot
after inflation. Do not touch them after
inflation.
If the air bag is deployed,the air bag will
not function again and must be replaced
immediately.If the air bag is not replaced, the
unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
²driver and passenger air bag modules (which
include the inflators and air bags),
²one or more impact and safing sensors,
²a readiness light and tone
²and the electrical wiring which connects the
components.
The diagnostic module monitors its own internal
circuits and the supplemental air bag electrical
system warning (including the impact sensors), the
system wiring, the air bag system readiness light, the
air bag back up power and the air bag ignitors.
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 readinesssection in
theInstrumentationchapter. Routine maintenance
of the air bag is not required.

BRAKES
Your service brakes are self-adjusting. Refer to the
scheduled maintenance guide for scheduled
maintenance.
Occasional brake noise is normal and often does not
indicate a performance concern with the vehicle's
brake system. In normal operation, automotive brake
systems may emit occasional or intermittent squeal
or groan noises when the brakes are applied. Such
noises are usually heard during the first few brake
applications in the morning; however, they may be
heard at any time while braking and can be
aggravated by environmental conditions such as
cold, heat, moisture, road dust, salt or mud. If a
ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking,
the brake linings may be worn-out and should be
inspected by a qualified service technician.
Anti-lock brake system (ABS) (if equipped)
On vehicles equipped with an anti-lock braking
system (ABS), a noise from the hydraulic pump
motor and pulsation in the pedal may be observed
during ABS braking events. Pedal pulsation coupled
with noise while braking under panic conditions or
on loose gravel, bumps, wet or snowy roads is
normal and indicates proper functioning of the
vehicle's anti-lock brake system. The ABS performs a
self-check at 17 km/h (10 mph) after you start the
engine and begin to drive away. A brief mechanical
noise may be heard during this test. This is normal.
If a malfunction is found, the ABS warning light will
come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the
vehicle should be inspected by a qualified service
technician.

Servicing after towing
If you tow a trailer for long distances, your vehicle
will require more frequent service intervals. Refer to
your Scheduled Maintenance guide for more
information.
Trailer towing tips
²Practice turning, stopping and backing up in an
area before starting on a trip to get the feel of the
vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs
and other obstacles.
²Allow more distance for stopping with a trailer
attached.
²The trailer tongue weight should be 10% of the
loaded trailer weight.
²After you have traveled 80 km (50 miles),
thoroughly check your hitch, electrical
connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in
hot weather, place the gearshift in P (Park) and
increase idle speed. This aids engine cooling and
air conditioner efficiency.
²Vehicles with trailers should not be parked on a
grade. If you must park on a grade, place wheel
chocks under the trailer's wheels.

Power distribution box
The power distribution box is located in the engine
compartment. The power distribution box contains
high-current fuses that protect your vehicle's main
electrical systems from overloads.
Always disconnect the battery before
servicing high current fuses.
Always replace the cover to the Power
Distribution Box before reconnecting the
battery or refilling fluid reservoirs.
If the battery has been disconnected and
reconnected, refer to theBatterysection of the
Maintenance and Carechapter.
