Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal safety system to tailor the air bag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety beltsection in this chapter.
Front safety belt pretensioners
The safety belt pretensioners are designed to tighten the safety belts
firmly against the occupant's body during a collision. This maximizes the
effectiveness of the safety belts and helps properly position the occupant
relative to the air bag to improve protection. The safety belt
pretensioners can be either activated alone or, if the collision is of
sufficient severity, together with the air bags.
Front safety belt energy management retractors
The front safety belt energy management retractors allow webbing to be
pulled out of the retractor in a gradual and controlled manner in
response to the occupant's forward momentum. This helps reduce the
risk of force-related injuries to the occupant's chest by limiting the load
on the occupant. Refer toSafety beltsection in this chapter.
Determining if the Personal safety system is operational
The Personal safety system uses a warning light in the instrument cluster
or a back-up tone to indicate the condition of the system. Refer to the
Warning lightsection in theInstrument clusterchapter. Routine
maintenance of the Personal safety system is not required.
The Restraints control module (RCM) monitors its own internal circuits
and the circuits for the air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and passenger occupant classification sensor (if
equipped). In addition, the RCM also monitors the restraints warning
light in the instrument cluster. A difficulty with the system is indicated
by one or more of the following.
²The warning light will either flash or stay lit.
²The warning light will not illuminate immediately after ignition is
turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.

The lap belt does not adjust
automatically. Insert the tongue into
the correct buckle (the buckle
closest to the direction the tongue is
coming from). To lengthen the belt,
turn the tongue at a right angle to
the belt and pull across your lap
until it reaches the buckle. To
tighten the belt, pull the loose end
of the belt through the tongue until
it fits snugly across the hips.
Shorten and fasten the belt when
not in use.

The air bags inflate and deflate
rapidly upon activation. After air bag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with
a deploying air bag may also cause abrasions, swelling or temporary
hearing loss. Because air bags must inflate rapidly and with 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.
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
²a diagnostic module
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.
Several air bag system components get hot after inflation. Do not
touch them after inflation.

SAFETY RESTRAINTS FOR CHILDREN
See the following sections for directions on how to properly use safety
restraints for children. Also seeAir bag supplemental restraint system
(SRS)in this chapter for special instructions about using air bags.
Important child restraint precautions
You are required by law to use safety restraints for children in the U.S.
and Canada. If small children ride in your vehicle (generally children who
are four years old or younger and who weigh 18 kg [40 lbs] or less), you
must put them in safety seats made especially for children. Check your
local and state or provincial laws for specific requirements regarding the
safety of children in your vehicle.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
Always follow the instructions and warnings that come with any infant or
child restraint you might use.
When possible, always place children under age 12 in the rear seat of
your vehicle. Accident statistics suggest that children are safer when
properly restrained in the rear seating positions than in the front seating
position.
Children and safety belts
If the child is the proper size, restrain the child in a safety seat.
Children who are too large for child safety seats (as specified by your
child safety seat manufacturer) should always wear safety belts.
Follow all the important safety restraint and air bag precautions that
apply to adult passengers in your vehicle.
If the shoulder belt portion of a combination lap and shoulder belt can
be positioned so it does not cross or rest in front of the child's face or
neck, the child should wear the lap and shoulder belt. Moving the child
closer to the center of the vehicle may help provide a good shoulder belt
fit.
Do not leave children, unreliable adults, or pets unattended in
your vehicle.

STARTING
Positions of the ignition
1. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
2. LOCK, locks the steering wheel,
automatic transmission gearshift
lever and allows key removal.
3. OFF, shuts off the engine and all
accessories without locking the
steering wheel.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. START, cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer toStarting the enginein this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.

Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
²the vehicle is raised for service
²the sound of the exhaust system changes
²the vehicle has been damaged in a collision
WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear contain or emit chemicals known
to the State of California to cause cancer and birth defects or other
reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet vents clear of snow,
leaves and other debris.
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 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.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.
Using ABS
²In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain full
steering control of your vehicle and, providing there is sufficient
space, will enable you to avoid obstacles and bring the vehicle to a
controlled stop.
²The anti-lock system does not decrease the time necessary to apply
the brakes or always reduce stopping distance. Always leave enough
room between your vehicle and the vehicle in front of you to stop.
Driving

²We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lampABS
TheABSwarning lamp in the instrument cluster momentarily illuminates
when the ignition is turned to the ON position. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)
Parking brake with auto-release
Apply the parking brake whenever
the vehicle is parked.
To set the parking brake:
1. Move the gearshift to P (Park).
2. Push pedal downward.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is fully released.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn off the ignition whenever you leave
your vehicle.
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
