Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during a frontal or near-frontal collision. This maximizes the effectiveness
of the safety belts and helps properly position the occupant relative to
the airbag to improve protection. The safety belt pretensioners can be
either activated alone or, if the collision is of sufficient severity, together
with the airbags.
Front safety belt energy management retractors
The front outboard 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 toEnergy management feature
section 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 theWarning 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 airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. 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.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at your dealership or by a qualified technician
immediately. Unless serviced, the system may not function properly in
the event of a collision.
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.

Conditions of operation
If... Then...
The driver’s safety belt is not
buckled before the ignition
switch is turned to the ON
position...The safety belt warning light
illuminates 1-2 minutes and the
warning chime sounds 4-8 seconds.
The driver’s safety belt is
buckled while the indicator
light is illuminated and the
warning chime is sounding...The safety belt warning light and
warning chime turn off.
The driver’s safety belt is
buckled before the ignition
switch is turned to the ON
position...The safety belt warning light and
indicator chime remain off.
BeltMinder
The BeltMinder
feature is a supplemental warning to the safety belt
warning function. This feature provides additional reminders by
intermittently sounding a chime and illuminating the safety belt warning
lamp in the instrument cluster when the driver’s and front passenger’s
safety belt is unbuckled.
The BeltMinder
feature uses information from the passenger occupant
classification sensor to determine if a front seat passenger is present and
therefore potentially in need of a warning. To avoid activating the
BeltMinder
feature for objects placed in the front passenger seat,
warnings will only be given to large front seat occupants as determined
by the passenger occupant classification sensor.
Both the driver’s and passenger’s safety belt usages are monitored and
either may activate the BeltMinder
feature. The warnings are the same
for the driver and the front passenger. If the BeltMinder
warnings have
expired (warnings for approximately 5 minutes) for one occupant (driver
or front passenger), the other occupant can still activate the
BeltMinder
feature.

Reasons given... Consider...
“I have an airbag” Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea.Peoplewho are
ejected are 40 times more likely
to DIE.Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.
Do not sit on top of a buckled safety belt to avoid the
BeltMinder
chime. Sitting on the safety belt will increase the
risk of injury in an accident. To disable (one-time) or deactivate the
BeltMinder
feature please follow the directions stated below.
One time disable
If at any time the driver/front passenger quickly buckles then unbuckles
the BeltMinder
feature for that seating position, the BeltMinder
is
disabled for the current ignition cycle. The BeltMinder
feature will
re-enable during the same ignition cycle if the occupant buckles and
remains buckled for approximately 30 seconds. Confirmation is not given
for the one time disable.
Deactivating/activating the BeltMinderfeature
The driver and front passenger BeltMinder
are
deactivated/activated independently. When deactivating/activating
one seating position, do not buckle the other position as this will
terminate the process.
Read Steps1-4thoroughly before proceeding with the
deactivation/activation programming procedure.
Note: The driver and front passenger BeltMinder
features must be
disabled/enabled separately. Both cannot be disable/enabled during the
same key cycle.
The driver and front passenger BeltMinder
features can be
deactivated/activated by performing the following procedure:
Before following the procedure, make sure that:
•The parking brake is set

•The gearshift is in P (Park) (automatic transmission)
•The ignition switch is in the OFF position
•The driver and front passenger safety belts are unbuckled
To reduce the risk of injury, do not deactivate/activate the
BeltMinder
feature while driving the vehicle.
1. Turn the ignition switch to the RUN (or ON) position. (DO NOT
START THE ENGINE)
2. Wait until the safety belt warning light turns off. (Approximately 1
minute)
•Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.
3. For the seating position being disabled, at a moderate speed, buckle
then unbuckle the safety belt 9 times, ending in the unbuckled state.
(Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.)
•After Step 3, the restraint system warning light (airbag light) will be
turned on for three seconds.
4. Within 10 seconds of the light turning on, at a moderate speed, buckle
then unbuckle the safety belt.
•This will disable the BeltMinder
feature for that seating position if it
is currently enabled. As confirmation, the restraint system warning
light will flash 4 times per second for 3 seconds.
•This will enable the BeltMinder
feature for that seating position if it
is currently disabled. As confirmation, the restraint system warning
light will flash 4 times per second for 3 seconds, followed by 3
seconds with the light off, then followed by the restraint system
warning light flashing 4 times per second for 3 seconds again.
Safety belt extension assembly
If the safety belt is too short when fully extended, there isa8inch(20
cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from your dealer at no cost.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.

Any alteration/modification to the front passenger seat may
affect the performance of the front passenger sensing system.
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 toAir bag readinesssection
in theInstrument Clusterchapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light will either
flash or stay lit.
•The readiness light will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Side air bag system (if equipped)
Do not place objects or mount equipment on or near the air bag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying air bag. Failure
to follow these instructions may increase the risk of personal injury in
the event of a collision.
Do not use accessory seat covers. The use of accessory seat
covers may prevent the deployment of the side air bags and
increase the risk of injury in an accident.
Do not lean your head on the door. The side air bag could injure
you as it deploys from the side of the seatback.

The fact that the air bags did not inflate 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. Side air bags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the side air bag has
deployed,the air bag will
not function again. The side
air bag system (including the
seat) must be inspected and
serviced by a qualified
technician in accordance with
the vehicle service manual.If
the air bag 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
side air bag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light as for front air bag system) will either
flash or stay lit.
•The readiness light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.

STARTING
Positions of the ignition
1. OFF/LOCK, shuts off the engine
and all accessories/locks the
gearshift lever and allows key
removal.
2. ACC, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
3. ON, all electrical circuits
operational. Warning lights
illuminated. Key position when driving.
4. START, cranks the engine. Release the key as soon as the engine
starts.
Refer to theSecurilock
passive anti-theft systemsection in the
Locks and Securitychapter for information on Securilock
keys.
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.

Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled,
normal braking is still effective. (If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
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 the ignition to the OFF/LOCK position
and remove the key 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
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Your vehicle has an automatic parking brake release. To release the
parking brake:
1. Start the vehicle.
2. Press the brake pedal.
3. Move the gearshift from the P (Park) position to one of the forward
gears (the parking brake will not release automatically when you shift
into reverse). The brake pedal must remain pressed while the gearshift is
moved.
