STARTING AND OPERATING 251

•Rock – Off road calibration only available in 4WD Low
range. The vehicle is raised (if equipped with Air
Suspension) for improved ground clearance. Traction
based tuning with improved steer-ability for use on high
traction off-road surfaces. Use for low speed obstacles
such as large rocks, deep ruts, etc. If equipped with air
suspension, the vehicle level will change to Off-Road 2.
If the Selec-Terrain switch is in ROCK mode, and the
transfer case is switched from 4WD Low to 4WD High,
the Selec-Terrain system will return to AUTO.
NOTE: Activate the Hill Descent Control or Selec Speed
Control for steep downhill control. See “Electronic Brake
Control System” in this section for further information.
Instrument Cluster Display Messages
When the appropriate conditions exist, a message will
appear in the instrument cluster. Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information.
FUEL SAVER TECHNOLOGY 5.7L ONLY — IF
EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine’s eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE: This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.

NOTE:
•If the sensor does not detect a vehicle ahead of you, ACC
will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or accelerate (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an ap-
propriate distance between vehicles.
• Normal (Fixed Speed) Cruise Control mode for cruising
at a constant preset speed. For additional information,
refer to “Normal (Fixed Speed) Cruise Control Mode” in
this section.
NOTE: Normal (Fixed Speed) Cruise Control will not react
to preceding vehicles. Always be aware of the mode
selected.
You can change the mode by using the Cruise Control
buttons. The two control modes function differently. Al-
ways confirm which mode is selected.

WARNING!(Continued)
•Will bring the vehicle to a complete stop while
following a target vehicle and hold the vehicle for
2 seconds in the stop position. If the target vehicle
does not start moving within two seconds the ACC
system will display a message that the system will
release the brakes and that the brakes must be
applied manually. An audible chime will sound
when the brakes are released.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy snow, sleet,
heavy traffic, and complex driving situations (i.e., in
highway construction zones).
• When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy, snow-
covered, slippery, or have steep uphill or downhill
slopes.
• When towing a trailer up or down steep slopes.
• When circumstances do not allow safe driving at a
constant speed.
Adaptive Cruise Control (ACC) Operation
The Speed Control buttons (located on the right side of the
steering wheel) operates the ACC system. NOTE:
Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning System.

Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
0 mph (0 km/h).
The minimum set speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the ready state, the
instrument cluster displays “ACC Ready.”
When the system is off, the instrument cluster displays
“Adaptive Cruise Control (ACC) Off.”
NOTE:You cannot engage ACC under the following con-
ditions:
• When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is applied.
• When the automatic transmission is in PARK, REVERSE
or NEUTRAL.
• When the vehicle speed is outside of the speed range.
• When the brakes are overheated.
• When the driver ’s door is open at low speeds.
• When the driver ’s seat belt is unbuckled at low speeds. •
ESC Full-Off Mode is active.To Activate/Deactivate
Push and release the Adaptive Cruise Control (ACC)
on/off button. The ACC menu in the instrument cluster
displays “ACC Ready.”
To turn the system off, push and release the Adaptive
Cruise Control (ACC) on/off button again. At this time, the
system will turn off and the instrument cluster displays
“Adaptive Cruise Control (ACC) Off.”

WARNING!
Leaving the Adaptive Cruise Control (ACC) system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have a collision. Always
leave the system off when you are not using it.
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the SET
(+)button or the SET (-)button and release. The instrument
cluster display will display the set speed. If the system is set when the vehicle speed is below 20 mph
(32 km/h), the set speed shall be defaulted to 20 mph
(32 km/h). If the system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be the current
speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary vehicle in
front of your vehicle in close proximity.
Remove your foot from the accelerator pedal. If you do not,
the vehicle may continue to accelerate beyond the set
speed. If this occurs:
• The message “DRIVER OVERRIDE” will display in the
instrument cluster display.
• The system will not be controlling the distance between
your vehicle and the vehicle ahead. The vehicle speed
will only be determined by the position of the accelera-
tor pedal.
To Cancel
The following conditions cancel the system:
•The brake pedal is applied.
• The CANC button is pushed.
• An Anti-Lock Brake System (ABS) event occurs.
