STARTING AND OPERATING
NOTE:
SPORT mode is not available when 4WD LOW is
selected.
SAND/MUD — Off-road calibration for use on low
traction surfaces such as mud, sand, or wet
grass. The 4WD system provides maximum
capability to all wheels. Some binding may be
felt on high traction surfaces. The electronic
brake system will be adjusted to reduce the
automatic braking of slipping wheels and to
allow the engine to operate without restriction.
ROCK — Off-road calibration is only available in
4WD LOW range. ROCK mode provides the most
aggressive four-wheel drive performance for
extreme off-road terrain. Use for low speed
obstacles such as large rocks, deep ruts, etc.
The driver may notice additional tire scrubbing
and steering wheel feedback while driving in
ROCK mode on higher traction off-road
surfaces. For use only in off-road driving situa-
tions.
NOTE:
ROCK mode is only available on the vehicles
equipped with the Off-Road package.
Activate the Hill Descent Control or Selec-Speed
Control for steep downhill control Ú page 170.
Instrument Cluster Display Messages
When the appropriate conditions exist, a message
will appear in the instrument cluster Ú page 74.
POWER STEERING
The power steering system will provide increased
vehicle response and ease of maneuverability. The
power steering system adapts to different driving
conditions.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.
If the "SERVICE POWER STEERING" or
"POWER STEERING ASSIST OFF -
SERVICE SYSTEM" message and a
steering wheel icon are displayed on the
instrument cluster display screen, it indicates that
the vehicle needs to be taken to an authorized
dealer for service. It is likely the vehicle has lost
power steering assistance Ú page 80.
If the "POWER STEERING SYSTEM HOT -
PERFORMANCE MAY BE LIMITED" message and an
icon are displayed on the instrument cluster
display screen, it indicates that extreme steering
maneuvers may have occurred, which caused an
over temperature condition in the power steering
system. You will lose power steering assistance
momentarily until the over temperature condition
no longer exists. Once driving conditions are safe,
pull over and let the vehicle idle for a few moments
until the light turns off Ú page 80.
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe-
cially at low speeds and during parking maneu-
vers.
If the condition persists, see an authorized
dealer for service.
STOP/START SYSTEM
The Stop/Start function was developed to reduce
fuel consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal or
pressing the accelerator pedal will automatically
restart the engine.
This vehicle has been upgraded with a heavy-duty
battery, starter, as well as other engine parts, to
handle the additional engine starts.
