Do not let children play with the moon roof. They may seriously
hurt themselves.
CELL PHONE USE
The use of Mobile Communications Equipment has become increasingly
important in the conduct of business and personal affairs. However,
drivers must not compromise their own or others’safety when using
such equipment. Mobile Communications can enhance personal safety
and security when appropriately used, particularly in emergency
situations. Safety must be paramount when using mobile communications
equipment to avoid negating these benefits.
Mobile Communication Equipment includes, but is not limited to cellular
phones, pagers, portable email devices, in vehicle communications
systems, telematics devices and portable two-way radios.
A driver’s first responsibility is the safe operation of the vehicle.
The most important thing you can do to prevent a crash is to
avoid distractions and pay attention to the road. Wait until it is safe to
operate Mobile Communications Equipment.
ELECTRONIC MESSAGE CENTER
The electronic message center only works when the ignition is in the ON
position.
The message center allows you to:
•see problems such as door ajar
and trunk ajar.
•check the on/off status of air
suspension, autolamp and speed
control systems.

Energy management feature
•This vehicle has a seat belt system with an energy management
feature at the front outboard seating positions to help further reduce
the risk of injury in the event of a head-on collision.
•This seat belt system has a retractor assembly that is designed to pay
out webbing in a controlled manner. This feature is designed to help
reduce the belt force acting on the occupant’s chest.
The front outboard and rear safety restraints in the vehicle are
combination lap and shoulder belts. The front outboard passenger and
rear seat safety belts have three types of locking modes described below:
Vehicle sensitive mode
This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of approximately 8 km/h (5
mph) or more, the combination safety belts will lock to help reduce
forward movement of the driver and passengers.
Webbing extraction sensitive mode
The webbing extraction sensitive mode stops the belt webbing from
retracting if it is pulled out too quickly.
Automatic locking mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt.
This mode should be usedany timea child safety seat is installed in the
vehicle. Children 12 years old and under should be properly restrained in
the rear seat whenever possible. Refer toSafety restraints for children
orSafety seats for childrenlater in this chapter.

If the parking brake fails to release
after completing this procedure, use
the manual parking brake release
lever.
Pull the lever to manually release
the parking brake.
TRACTION CONTROL
For Traction Controlwarning lights refer toWarning Lightsin the
Instrument clusterchapter.
Your vehicle is equipped with a Traction Controlsystem (except on
commercial conversion packages). This system helps you maintain the
stability and steerability of your vehicle, especially on slippery road
surfaces such as snow- or ice-covered roads and gravel roads. The
system will allow your vehicle to make better use of available traction in
these conditions.
During Traction Controloperation, you may hear an electric motor
type of sound coming from the engine compartment and the engine will
not“rev-up”when you push further on the accelerator. This is normal
system behavior and should be no reason for concern.
The Traction Controlswitch,
located on the left side of the
instrument panel, allows the driver
to enable and disable the system.
The Traction Controlsystem will
automatically turn on every time the
ignition is turned OFF and RUN.
If you should become stuck in snow
or ice or on a very slippery road surface, try switching the Traction
Controlsystem off. This may allow excess wheel spin to“dig”the
vehicle out and enable a successful“rocking”maneuver.

•Selecting 2 (Second) at higher speeds will cause the transmission to
downshift to second gear at the appropriate vehicle speed.
1 (First)
•Provides maximum engine braking.
•Allows upshifts by moving gearshift lever.
•Will not downshift into 1 (First) at high speeds; allows for 1 (First)
when vehicle reaches slower speeds.
Forced downshifts
•Allowed in
(Overdrive) or Drive.
•Depress the accelerator to the floor.
•Allows transmission to select an appropriate gear.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting from forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
If necessary, try turning the Traction Controlsystem off. This will allow
the wheels to spin, which may help to free your stuck vehicle. For more
information, refer toTraction Control(if equipped)in this chapter.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The extended rear park aid system sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) gear is selected.
To help avoid personal injury, please read and understand the
limitations of the extended rear park assist system as contained
in this section. The park assist is only an aid for some (generally large
and fixed) objects when moving in reverse on a flat surface at“parking
speeds”. Inclement weather may also affect the function of the RSS;
this may include reduced performance or a false activation.
