274 STARTING AND OPERATING
This electronically shifted transfer case is designed to be
driven in the two–wheel drive position (2WD) for normal
street and highway conditions on dry hard surfaced roads).
Driving the vehicle in 2WD will have greater fuel economy
benefits as the front axle is not engaged in 2WD.
When additional traction is required, the transfer case 4WD
HIGH and 4WD LOW positions can be used to maximize
torque to the front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This is accomplished by
pushing the desired position on the 4WD control switch.
Refer to “Shifting Procedure” in this section for specific
shifting instructions.
The 4WD HIGH and 4WD LOW positions are designed for
loose, slippery road surfaces only. Driving in the 4WD HIGHand 4WD LOW positions on dry hard surfaced roads may
cause increased tire wear and damage to the driveline
components.
NOTE:
The transfer case NEUTRAL button is located in the center of
the 4WD Control Switch and is pushed by using a ballpoint
pen or similar object. The transfer case NEUTRAL position is
to be used for recreational towing only. Refer to “Recre
-
ational Towing” in “Starting And Operating” for further
information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located in the instrument cluster and indicate the
current and desired transfer case selection. When you select
a different transfer case position, the indicator lights will do
the following:
If All Of The Following Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until the transfer case completes the shift.
• The transmission may not engage PARK if the vehicle
is moving. Always bring the vehicle to a complete stop
before shifting to PARK, and verify that the transmis -
sion gear position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly indicated,
before exiting the vehicle.

WARNING!
• Adaptive Cruise Control (ACC) is a convenience system. It is not a substitute for active driving involve -
ment. It is always the driver’s responsibility to be atten -
tive of road, traffic, and weather conditions, vehicle
speed, distance to the vehicle ahead; and, most impor -
tantly, brake operation to ensure safe operation of the
vehicle under all road conditions. Your complete atten -
tion is always required while driving to maintain safe
control of your vehicle. Failure to follow these warn -
ings can result in a collision and death or serious
personal injury.
• The ACC system: • Does not react to pedestrians, oncoming vehicles,and stationary objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
• Cannot take street, traffic, and weather conditions into account, and may be limited upon adverse sight
distance conditions.
• Does not always fully recognize complex driving conditions, which can result in wrong or missing
distance warnings.
• Will bring the vehicle to a complete stop whilefollowing a target vehicle and hold the vehicle for
approximately two seconds in the stop position. At
this point, there will be an “ACC may cancel soon”
chime and warning to the driver. When ACC is
cancelled, the system will release the brakes and the
driver must take over braking. The system can be
resumed when the target vehicle drives off by
releasing the brake and pushing the resume button
on the steering wheel.
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.
WARNING! (Continued)

STARTING AND OPERATING 295
• The ACC system decelerates the vehicle to a full stop whenfollowing a target vehicle. If an ACC host vehicle follows a
target vehicle to a standstill, after two seconds the driver
will either have to push the RES (+) button, or apply the
accelerator pedal to reengage the ACC to the existing set
speed.
• The ACC system maintains set speed when driving up hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill. This
is normal operation and necessary to maintain set speed.
When driving up hill and down hill, the ACC system will
cancel if the braking temperature exceeds normal range
(overheated).Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC calcu-
lates and sets the distance to the vehicle ahead. This distance
setting displays in the instrument cluster display.
Distance Setting 4 Bars (Longest)

Brake Alert
NOTE:
The “Brake!” Screen in the instrument cluster display is a
warning for the driver to take action and does not necessarily
mean that the Forward Collision Warning system is
applying the brakes autonomously.
Trailer Detect — If Equipped
When a trailer is detected, the ACC system automatically
defaults to the longest setting (four bars). The setting can be
overridden by pushing the Distance Button on the steering
wheel.
Overtake Aid
When driving with ACC engaged and following a vehicle,
the system will provide an additional acceleration up to the
ACC set speed to assist in passing the vehicle. This addi -
tional acceleration is triggered when the driver utilizes the
left turn signal and will only be active when passing on the
left hand side.
ACC Operation At Stop
In the event that the ACC system brings your vehicle to a
standstill while following a target vehicle, if the target
vehicle starts moving within two seconds of your vehicle
coming to a standstill, your vehicle will resume motion
without the need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, then ACC will
cancel and the driver must take over braking. When the
target vehicle drives off, ACC can be resumed by releasing
the brake and pushing the RES (+) button.

Integrated Trailer Brake Module — If Equipped
Your vehicle may have an Integrated Trailer Brake Module
(ITBM) for Electric and Electric Over Hydraulic (EOH) trailer
brakes.
NOTE:
This module has been designed and verified with electric
trailer brakes and new electric over hydraulic systems. Some
previous EOH systems may not be compatible with ITBM.Integrated Trailer Brake Module (ITBM) The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to activate
power to the trailer's electric brakes independent of the tow
vehicle's brakes. If the manual brake control lever is acti
-
vated while the brake is also applied, the greater of the two
inputs determines the power sent to the trailer brakes.
The trailer and the vehicle’s stop lamps will come on when
braking normally with the vehicle brake pedal. Only the
trailer stop lamps will come on when the manual brake
control lever is applied.
Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection status.
If no electrical connection is detected after the ignition is
turned on, pushing the GAIN adjustment button or sliding
the manual brake control lever will display the GAIN setting
for 10 seconds and the “Trailer Brake Status Indicator Light”
will not be displayed.
If a fault is detected in the trailer wiring or the Integrated
Trailer Brake Module (ITBM), the “Trailer Brake Status Indi -
cator Light” will flash.

362 STARTING AND OPERATING
• The ignition must be in the ON/RUN mode for a shift totake place and for the position indicator lights to be oper -
able. If the ignition is not in the ON/RUN mode, the shift
will not take place and no position indicator lights will be
on or flashing.
• A flashing NEUTRAL (N) position indicator light indi -
cates that shift requirements have not been met.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop, leaving it connected to the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine, and shift the transmission into NEUTRAL.
• With manual shift transfer case, shift the transfer case lever to the desired position.
• With electronic shift transfer case with rotary selector switch, push and hold the transfer case NEUTRAL (N)
button until the NEUTRAL (N) indicator light turns off. After the NEUTRAL (N) indicator light turns off,
release the NEUTRAL (N) button. After the NEUTRAL

cator light turns on.
NOTE:
When shifting out of transfer case NEUTRAL (N), turning
the engine OFF is not required, but may be helpful to avoid
gear clash. With 8-speed automatic transmission, the engine
must remain running, since turning the engine OFF will shift
the transmission to PARK (and the transmission must be in
NEUTRAL for the transfer case to shift out of NEUTRAL).
5. Turn the engine OFF. Shift automatic transmission into PARK. On 8-speed transmissions the shifter will auto -
matically select PARK when the engine is turned off.
6. Release the brake pedal.
