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 modifications to
the vehicle will effect the performance of the
Adaptive Cruise Control.
Activating Adaptive Cruise Control
(ACC)
You can only activate ACC if the vehicle speed
is above 25 mph (40 km/h).
When the system is turned on and in the READY
state, the Electronic Vehicle Information Center
(EVIC) displays “Adaptive Cruise Ready.”
When the system is OFF, the EVIC displays
“Adaptive Cruise Control Off.”
NOTE:
You cannot enable ACC under the following
conditions:
•
When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is set.
• When the automatic transmission is in
PARK, REVERSE or NEUTRAL.
• When pushing the RES + button without a
previously set speed in memory.
To ActivatePush and release the ON/OFF button. The ACC
menu in the EVIC displays “Adaptive Cruise
Ready.”
To turn the system OFF, push and release the
ON/OFF button again. At this time, the system
will turn off and the EVIC will display “Adaptive
Cruise Control Off.”

NOTE:
If ACC is resumed or set with the ESC/TCS
off, ESC will automatically be re-engaged.
To Turn OffThe system will turn off and erase the set speed
in memory if:
•You push and release the ON/OFF button.
• You turn OFF the ignition.
• You switch off ESC.
• You switch to Four-Wheel Drive Low.
To Resume SpeedPress the RES +button and release. Then
remove your foot from the accelerator pedal.
The EVIC will display the last set speed.
NOTE:
You can resume ACC from a minimum of
20 mph (32 km/h).
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. This could
cause a collision and/or serious injury.
To Vary the Speed SettingWhile ACC is set, you can increase the set
speed by pressing and holding the RES +
button. If the button is continually pressed, the
set speed will continue to increase in 5 mph
(10 km/h) increments until the button is re-
leased. The increase in set speed is reflected in
the EVIC display. Pressing the RES
+button once will result in a
1 mph (2 km/h) increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph (2 km/h).
While ACC is set, the set speed can be de-
creased by pressing and holding the SET -
button. If the button is continually pressed, the
set speed will continue to decrease in 5 mph
(10 km/h) increments until the button is re-
leased. The decrease in set speed is reflected
in the EVIC display.
Pressing the SET -button once will result in a
1 mph (2 km/h) decrease in set speed. Each
subsequent tap of the button results in a de-
crease of 1 mph (2 km/h).
NOTE:
• When you use the SET - button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.
• The ACC system can only apply a maxi-
mum of 25% of the vehicle’s braking ca-
pability and will not bring the vehicle to a
complete stop.

To Resume
Press the RES+button and then remove your
foot from the accelerator pedal. The EVIC will
display the last set speed.
To Turn Off
The system will turn off and erase the set speed
in memory if:
• You push and release the ON/OFF button.
• You turn off the ignition.
• You switch off ESC.
• You engage Four-Wheel Drive Low.
If the Cruise Control system is turned off and
reactivated, the system will return to the last
driver setting (ACC or Normal Cruise Control).Forward Collision Warning —
If Equipped
Forward Collision Warning (FCW) warns the
driver of a potential collision with the vehicle in
front of you and prompts the driver to take
action in order to avoid the collision.
FCW monitors the information from the forward
looking sensor as well as the Electronic Brake
Controller (EBC), wheel speed sensors, i.e., to
calculate a probable rear-end collision. When
the system determines that a rear-end collision
is probable a visual warning is displayed on the
EVIC, and an audible warning is also provided.
When the system determines a collision with
the vehicle in front of you is no longer probable,
the warning message will be deactivated.
WARNING!
Forward Collision Warning (FCW) is not in-
tended to avoid a collision on its own. The
driver has the responsibility to avoid a colli-
sion by controlling the vehicle via braking and
steering. Failure to follow this warning could
lead to serious injury or death.
FCW Message

The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake
is applied. It does not show the degree of
brake application.
15. Anti-Lock Brake (ABS) LightThis light monitors the Anti-Lock
Brake System (ABS). The light will
turn on when the ignition switch is
turned to the ON/RUN position and
may stay on for as long as four
seconds.
If the ABS light remains on or turns on while
driving, it indicates that the Anti-Lock portion of
the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally
if the BRAKE warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock brakes. If the ABS light
does not turn on when the ignition switch is turned to the ON/RUN position, have the light
inspected by an authorized dealer.
16. 4 LOW
This light alerts the driver that the
vehicle is in the four-wheel drive
LOW mode. The front and rear
driveshafts are mechanically
locked together forcing the front
and rear wheels to rotate at the
same speed. Low range provides a greater
gear reduction ratio to provide increased
torque at the wheels.
For further information on four-wheel drive op-
eration and proper use, refer to “Four-Wheel
Drive Operation — If Equipped” in “Starting
And Operating”.
17. Speedometer
Indicates vehicle speed.
18. Fuel Door Reminder The fuel pump symbol points to the
side of the vehicle where the fuel
door is located. 19. Fuel Gauge
The pointer shows the level of fuel in the fuel
tank when the ignition switch is in the ON/RUN
position.
20. Electronic Vehicle Information Center
(EVIC) White Telltale Area
This area will display the EVIC reconfigurable
white telltales. For further information refer to
“Electronic vehicle Information Center (EVIC)”.
21. Electronic Vehicle Information Center
(EVIC) Amber Telltale Area
This area will display the EVIC reconfigurable
amber caution telltales. For further information
refer to “Electronic vehicle Information Center
(EVIC)”.
22. Electronic Vehicle Information Center
(EVIC) Red Telltale Area
This area will display the EVIC reconfigurable
red telltales. For further information refer to

For example, if the driver shifts the transmission
into ERS 3 (third gear), the transmission will
never shift above third gear, but can shift down
to 2 (second) or 1 (first), when needed.
NOTE:
•If you pull and hold (not tap) the shift lever
to the left (-), the transmission will down-
shift to the lowest gear that can be at-
tained without overrevving the engine.
The display will show the gear the vehicle
is in and will limit the top gear to the one
displayed.
•
If you push and hold (not tap) the shift
lever to the right (+), the transmission will
exit the gear limiting mode and shift to the
appropriate gear. The display will read D .
3.6L and 3.0L Diesel Engine
When in the DRIVE position, the first tap to the
left (-) will shift down one gear and will display
that gear. For example, if you are in DRIVE and
are in fifth gear, when you tap the shift lever one
time to the left (-), the transmission will down-
shift to fourth gear and the display will show 4.
Another tap to the left (-) will shift the transmis-
sion into third gear. 5.7L Engine
On vehicles equipped with the 5.7L engine,
use of ERS (or TOW/HAUL mode) also enables
an additional underdrive gear which is not
normally used during through-gear accelera-
tions. This additional gear improves vehicle
performance and cooling capability when tow-
ing a trailer on certain grades. ERS 1, 2, and 3
are underdrive gears; ERS 4 is direct drive. ERS
5 (Overdrive) is the same as the normal 4th
gear. When in the DRIVE position in first through
fourth gear, the first tap to the left (-) will display
the ERS designation for the current gear (the
transmission will not downshift). For example, if
you are in DRIVE and are in third (direct) gear,
when you tap the shift lever one time to the left
(-), the display will show 4 (ERS 4 is direct
gear). Another tap to the left (-) will shift the
transmission down to ERS 3 (the added under-
drive gear). When in the DRIVE position in fifth
gear, the first tap to the left (-) will downshift the
transmission and display 5 (ERS 5 is the same
as normal fourth gear). Another tap to the left (-)
will shift the transmission down to ERS 4 (direct
gear).
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid.

* Applies to vehicles equipped with 5.7L
engines only.
NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), move
the shift lever to the left “D(-)” and hold it
there. The transmission will shift to the
range from which the vehicle can best be
slowed down.
207

•If the vehicle has not been driven in sev-
eral days, the first few seconds of opera-
tion after shifting the transmission into
gear may seem sluggish. This is due to
the fluid partially draining from the torque
converter into the transmission. This con-
dition is normal and will not cause dam-
age to the transmission. The torque con-
verter will refill within five seconds after
starting the engine.
Rocking the VehicleIf the vehicle becomes stuck in snow, sand, or
mud, it can often be moved by a rocking
motion. Move the shift lever between DRIVE
and REVERSE, while applying slight pressure
to the accelerator.
NOTE:
The Electronic Stability Control (ESC) and
Traction Control System (TCS) (if equipped)
should be turned OFF before attempting to
rock the vehicle. Refer to “Electronic Brake
Control System” in “Starting and Operating”
for further information. The least amount of accelerator pedal pressure
to maintain the rocking motion, without spinning
the wheels or racing the engine, is most effec-
tive. Racing the engine or spinning the wheels
may lead to transmission overheating and fail-
ure. Allow the engine to idle with the shift lever
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmission
failure during prolonged efforts to free a stuck
vehicle.CAUTION!
When “rocking” a stuck vehicle by moving
between “First” and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h) or
drivetrain damage may result.
