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 to Safety Belt section in this chapter.
Front safety belt pretensioners
The front outboard safety belt pretensioners are designed to tighten the
safety belts of the driver and front ouboard passenger 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 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 to Safety Belt 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 the Warning Light section in the Instrument Cluster chapter.
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, 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 the 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.

Front and second row safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver, right
front passenger and second row
outboard passengers. Adjust the
height of the shoulder belt so the
belt rests across the middle of your
shoulder.
To lower the shoulder belt height,
push the button and slide the height
adjuster down. To raise the height
of the shoulder belt, push the
button and slide the height adjuster
up. Pull down on the height adjuster
to make sure it is locked in place.
Position the safety belt
height adjusters so that the
belt rests across the middle of
your shoulder. Failure to adjust
the safety belt properly could
reduce the effectiveness of the
seat belt and increase the risk of
injury in a collision.
Safety belt warning light and indicator chime
The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.

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.
Using ABS
• In 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 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.
• The anti-lock system does not always reduce stopping distance.
Always leave enough room between your vehicle and the vehicle in
front of you to stop.
• We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lamp ABS
The ABS
warning 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.)
Brake Assist (if equipped)
The Brake Assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and
maximizes the amount of brake booster assist, helping the driver to
achieve maximum braking pressure. Once a panic brake application is
detected, the system will remain activated as long as the brake pedal is
depressed. The system is deactivated by releasing the brake pedal.
When the system activates, the brake pedal will travel with very little
effort; this is normal. P!BRAKE

Parking brake with auto-release (if equipped)
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is released.
Always set the parking brake fully and make sure that the
gearshift is securely latched in P (Park).
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. Turn the ignition to the ON position.
2. Press the brake pedal.
3. Move the gearshift out of the P (Park) position (the parking brake will
release automatically when you shift into reverse). The brake pedal must
remain pressed while the gearshift is moved.

The Roll Stability Control button
allows the driver to control the
availability of the Roll Stability
Control system. The Roll Stability
Control system status is indicated
by a warning indicator light with a
“ sliding car ” icon in the instrument cluster that will flash when the
system is activated and an indicator light in the control button that will
illuminate when the system is turned off. In vehicles with a message
center, the message “ Roll Stability Control OFF ” will be displayed.
If a failure is detected in the Roll Stability Control system, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced immediately.
Pressing the button once will disable the Roll Stability Control stability
enhancement and the engine power reduction portion of the traction
enhancement feature; the brake portion of the traction enhancement
feature will still function normally. Pressing and holding the button for
more than five seconds will disable the Roll Stability Control stability
enhancement and traction enhancement feature. If the vehicle is stuck
in snow or mud or when driving in deep sand, switching off the Roll
Stability Control system may be beneficial so the wheels are allowed to
spin. If your vehicle seems to lose engine power while driving in deep
sand or very deep snow, switching off the Roll Stability Control stability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
Roll Stability Control performs a system self-check. During Roll Stability
Control operation you may experience the following:
• A rumble or grinding noise
• A slight deceleration of the vehicle
• The Roll Stability Control indicator light will flash
• If your foot is on the brake pedal, you will feel a vibration in the
pedal.
• If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during Roll Stability Control operation. O

(Overdrive) can be deactivated
by pressing the transmission control
switch (TCS) on the end of the
gearshift lever.
The transmission control indicator
light (TCIL) will illuminate in the
instrument cluster.
Drive – Not shown on the display. Activate by pressing the transmission
control switch (TCS) on the end of the gearshift lever with the gearshift
in the position. The TCIL will illuminate in the instrument cluster.
Transmission operates in gears one through three. (Drive) provides
more engine braking than (Overdrive) and is useful when:
• driving with a heavy load.
• towing a trailer up or down steep hills.
• additional engine downhill braking is desired. If towing a trailer, refer
to Driving while you tow in the Trailer towing section.
To return to
(Overdrive) mode, press the transmission control switch
(TCS). The TCIL will no longer be illuminated.
Each time the vehicle is started, the transmission will automatically
return to normal overdrive mode.
Every time the vehicle is shut off and restarted, you must press the
transmission control switch to cancel overdrive operation if driving in
overdrive is not desired. P

Positions of the Control Trac system
The Control Trac system functions
in four modes:
• 2H (2WD HIGH) delivers power
to the rear wheels only. This is
appropriate for normal on-road
driving on dry pavement.
• A4WD (4X4 AUTO) provides
electronic control four-wheel
drive with power delivered to all
four wheels, as required, for
increased traction. This is appropriate for all on-road driving
conditions, such as dry road surfaces, wet pavement, snow or gravel.
• 4H (4X4 HIGH) provides mechanically locked four-wheel drive power
to front and rear wheels. The “ 4X4 ” light will illuminate in the
instrument cluster when this position is selected. This position is not
recommended for use on dry pavement. This position is only intended
for severe winter or off-road conditions, such as deep snow, ice or
shallow sand.
• 4L (4X4 LOW) provides mechanically locked four-wheel drive when
extra power at reduced speeds is required. The “ 4X4 LOW ” light will
illuminate in the instrument cluster when this position is selected.
This position is not recommended for use on dry pavement. Use this
position for off-road low-speed operation or when extra power is
required, such as climbing steep grades, going through deep sand or
pulling a boat out of the water.
Note: If your vehicle is equipped with AdvanceTrac
, the
AdvanceTrac
system will automatically turn off the stability
enhancement feature when you shift the Control Trac A4WD system into
4L (4X4 LOW). The brake traction enhancement feature will still be
enabled.
The AdvanceTrac
stability enhancement system can be turned off
manually by pressing the AdvanceTrac
button (refer to AdvanceTrac

Stability Enhancement System in this chapter) while operating in 2H,
A4WD or 4H while driving in deep sand, very deep snow or more
strenuous off-road maneuvers. This will disable the engine management
feature, allowing the vehicle to maintain full power and enhanced
momentum through the obstacle.
