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.

STARTING AND OPERATING 357
Over The Road Operation With Snowplow Attached
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface condi-
tions permit. Do not exceed 40 mph (64 km/h). The operator
should always maintain a safe stopping distance and allow
adequate passing clearance.
Operating Tips
Under ideal snow plowing conditions, 20 mph (32 km/h)
should be maximum operating speed. The operator should
be familiar with the area and surface to be cleaned. Reduce
speed and use extreme caution when plowing unfamiliar
areas or under poor visibility. General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer's instructions.
Keep all snowplow electrical connections and battery termi
-
nals clean and free of corrosion.
When plowing snow, to avoid transmission and drivetrain
damage, the following precautions should be observed.
• Operate with transfer case in 4LO when plowing small or congested areas where speeds are not likely to exceed
15 mph (24 km/h). At higher speeds operate in 4HI.
• Vehicles with automatic transmissions should use 4LO range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
• Do not shift the transmission unless the engine has returned to idle and wheels have stopped. Make a practice
of stepping on the brake pedal while shifting the transmis -
sion.

3. Press and hold the brake pedal.
4. Shift the transfer case into NEUTRAL:• With manual shift transfer case, shift the transfer caselever into NEUTRAL (N).
• With electronic shift transfer case, push and hold the transfer case NEUTRAL (N) button. Some models have
a small, recessed "N" button (at the center of the
transfer case switches) that must be pressed using a
ballpoint pen or similar object. Other models have a
rectangular NEUTRAL switch, below the rotary
transfer case control knob. The NEUTRAL (N) indi -
cator light will blink while the shift is in progress. The
light will stop blinking (stay on solid) when the shift to
NEUTRAL (N) is complete. After the shift is completed
and the NEUTRAL (N) light stays on, release the
NEUTRAL (N) button.
5. Release the parking brake.
6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds and ensure that there is no vehicle movement.
8. Repeat steps six and seven with automatic transmission in DRIVE. 9. Shift the transmission to NEUTRAL. Firmly apply the
parking brake. Turn OFF the engine. For vehicles with
Keyless Enter-N-Go, push and hold the ENGINE
START/STOP button until the engine shuts off.
10. Shift the transmission into PARK.
11. Place the ignition in the OFF mode, and remove the key fob.
12. Attach the vehicle to the tow vehicle using a suitable tow bar.
13. Release the parking brake.
NOTE:
With electronic shift transfer case:
• Steps 2 through 3 are requirements that must be met before pushing the NEUTRAL (N) button, and must continue to
be met until the shift has been completed. If any of these
requirements are not met before pushing the NEUTRAL
(N) button or are no longer met during the shift, the
NEUTRAL (N) indicator light will flash continuously until
all requirements are met or until the NEUTRAL (N) button
is released.

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
(N) button has been released, the transfer case will shift
to the position indicated by the selector switch.
• With electronic shift transfer case with push-button selector switch, push and hold the switch for the
desired transfer case position, until the NEUTRAL (N)
indicator light turns off and the desired position indi -
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.
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.

9. Press and hold the brake pedal.
10. Release the parking brake.
11. Shift the transmission into gear, release the brake pedal,and check that the vehicle operates normally.
NOTE:
With electronic shift transfer case:
• Steps 3 and 4 are requirements that must be met before pushing the button to shift out of NEUTRAL (N), and must
continue to be met until the shift has been completed. If
any of these requirements are not met before pushing the
button or are no longer met during the shift, the
NEUTRAL (N) indicator light will flash continuously until
all requirements are met or until the button is released.
• The ignition must be in the ON/RUN mode for a shift to take 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.DRIVING TIPS
Driving On Slippery Surfaces
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice, snow,
wet, mud, loose sand, etc.).

364 STARTING AND OPERATING
Driving Through Water
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and prevent
damage to your vehicle.
Flowing/Rising WaterShallow Standing Water
Although your vehicle is capable of driving through shallow
standing water, consider the following Cautions and Warn
-
ings before doing so.
WARNING!
Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing
water can wear away the road or path's surface and cause
your vehicle to sink into deeper water. Furthermore,
flowing and/or rising water can carry your vehicle away
swiftly. Failure to follow this warning may result in
injuries that are serious or fatal to you, your passengers,
and others around you.
WARNING!
• Driving through standing water limits your vehicle’s traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
• Driving through standing water limits your vehicle’s braking capabilities, which increases stopping
distances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake pedal
several times to dry the brakes.
• Failure to follow these warnings may result in injuries that are serious or fatal to you, your passengers, and
others around you.

• You can also turn the temperature control to maximumheat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine
cooling system.GEAR SELECTOR OVERRIDE — 6–SPEED
TRANSMISSION
If a malfunction occurs and the gear selector cannot be
moved out of the PARK (P) position, you can use the
following procedure to temporarily move the gear selector:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Tilt the steering wheel to the full up position.
4. Press and maintain firm pressure on the brake pedal.
5. Insert a screwdriver or similar tool into the access port (ringed circle) on the bottom of the steering column, and
push and hold the override release lever up.
WARNING!
You or others can be badly burned by hot engine coolant
(antifreeze) or steam from your radiator. If you see or
hear steam coming from under the hood, do not open the
hood until the radiator has had time to cool. Never try to
open a cooling system pressure cap when the radiator or
coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on HOT (H),
and you hear continuous chimes, turn the engine off
immediately and call for service.

6. Move the gear selector to the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
MANUAL PARK RELEASE — 8–SPEED
TRANSMISSION
In order to push or tow the vehicle in cases where the trans -
mission will not shift out of PARK (P) (such as a dead
battery), a Manual Park Release is available.
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the driver’s
seat with your foot firmly on the brake pedal when
activating the Manual Park Release. Activating the
Manual Park Release will allow your vehicle to roll away
if it is not secured by the parking brake, or by proper
connection to a tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.
