STARTING AND OPERATING161
This electronically shifted transfer case provides
four positions:
Two-Wheel Drive High Range (2WD) — This
range is for normal street and highway driving
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.
Four-Wheel Drive High Range (4WD HIGH) —
This range provides torque to the front drive -
shaft (engages four-wheel drive) which allows
front and rear wheels to spin at the same speed.
This provides additional traction for loose or
slippery road surfaces only.
Four-Wheel Drive Low Range (4WD LOW) — This
range provides low speed four-wheel drive. It
maximizes torque (increased torque over 4WD
HIGH) to the front driveshaft; allowing front and
rear wheels to rotate at the same speed. This
range provides additional traction and
maximum pulling power for loose or slippery
road surfaces only. Do not exceed 25 mph
(40 km/h) in this range.
N (Neutral) — This range disengages both the
front and rear driveshafts from the powertrain.
To be used for flat towing behind another
vehicle Ú page 228.
NOTE:
The 4WD HIGH and 4WD LOW positions are
designed for loose, slippery road surfaces only.
Driving in the 4WD HIGH and 4WD LOW posi -
tions on dry, hard surfaced roads may cause
increased tire wear and damage to the driveline
components.
The transfer case N (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 N (Neutral) position is
to be used for recreational towing only
Ú page 228.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD
HIGH and 4WD LOW) 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:
1. The current position indicator light will turn off.
2. The selected position indicator light will flash until the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and
remain on.
If the transfer case does not shift into the desired
position, one or more of the following events may
occur:
1. The indicator light for the current position will remain on.
2. The newly selected position indicator light will continue to flash.WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (Neutral) position without first
fully engaging the parking brake. The transfer
case N (Neutral) position disengages both the
front and rear drive shaft from the powertrain,
and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake
should always be applied when the driver is
not in the vehicle.
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 transmission gear position indi -
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.

164STARTING AND OPERATING
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD
HIGH, 4WD LOW, and 4WD AUTO) 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:
1. The current position indicator light will turn off.
2. The selected position indicator light will flash until the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and
remain on.
If the transfer case does not shift into the desired
position, one or more of the following events may
occur:
1. The indicator light for the current position will remain on.
2. The newly selected position indicator light will continue to flash.
3. If the transfer case will not shift, there will be a
cluster message stating the 4WD shift has
canceled.
NOTE:Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met. To retry the
selection, push the current position, wait five
seconds, and retry selection.
The SERV 4WD Warning Light monitors the
electronic shift four-wheel drive system. If this light
remains on after engine start-up or illuminates
during driving, it means that the four-wheel drive
system is not functioning properly and that service
is required.
NOTE:Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD, 4WD AUTO or 4WD HIGH positions at a
given road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h). Proper operation of four-wheel drive vehicles
depends on tires of equal size, type and
circumference on each wheel. Any difference in
tire size can cause damage to the drivetrain.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe turning
and stopping speeds. Do not go faster than road
conditions permit.
Shifting Procedure
If any of the requirements to select a new
transfer case position have not been met, then
the transfer case will not shift. The position indi
-
cator light for the previous position will remain
on and the newly selected position indicator
light will continue to flash until all the require -
ments for the selected position have been met.
If all the requirements to select a new transfer
case position have been met, then the current
position indicator light will turn off and the
selected position indicator light will flash until
the transfer case completes the shift. When the
shift is complete, the position indicator light for
the selected position will stop flashing and
remain on.
WARNING!
Always engage the parking brake when powering
down the vehicle if the SERV 4WD Warning Light
is illuminated. Not engaging the parking brake
may allow the vehicle to roll which may cause
personal injury or death.

RUN position or the engine running for all user
requested changes. When lowering the vehicle, all
of the doors must be closed. If a door is opened at
any time while the vehicle is lowering, the change
will not be completed until the open door(s) is
closed.
This system uses a lifting and lowering pattern
which keeps the headlights from incorrectly
shining into oncoming traffic. When raising the
vehicle, the rear of the vehicle will move up first
and then the front. When lowering the vehicle, the
front will move down first and then the rear.
After the engine is turned off, it may be noticed that
the air suspension system operates briefly; this is
normal. The system is correcting the position of the
vehicle to ensure a proper appearance.
To assist with changing a spare tire, the air
suspension system has a feature which allows the
automatic leveling to be disabled Ú

22_DT_OM_EN_USC_t.book Page 170

182STARTING AND OPERATING
When ACC Is Active
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system decelerates the vehicle to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
after two seconds the driver will either have to
push the RES (resume) button, or apply the
accelerator pedal to reengage the ACC to the
existing set speed.
The ACC system maintains set speed when
driving uphill and downhill. 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 uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for Adaptive
Cruise Control (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 calculates and sets the distance to the vehicle
ahead. This distance setting displays in the
instrument cluster display.
Distance Settings
To increase the distance setting, push the
Distance Increase button and release. Each time
the button is pushed, the distance setting
increases by one bar (longer).
To decrease the distance setting, push the
Distance Decrease button and release. Each time
the button is pushed, the distance setting
decreases by one bar (shorter). If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster displays the ACC Set With Target Detected
Indicator Light, and the system adjusts vehicle
speed automatically to maintain the distance
setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE!” will flash in the
instrument cluster display and a chime will sound
while ACC continues to apply its maximum braking
capacity.

Display Messages
The trailer brake control interacts with the
instrument cluster display. Display messages,
along with a single chime, will be displayed
when a malfunction is determined in the trailer
connection, trailer brake control, or on the trailer
Ú page 114.
NOTE:
An aftermarket controller may be available for
use with trailers with air or EOH trailer brake
systems. To determine the type of brakes on
your trailer and the availability of controllers,
check with your trailer manufacturer or dealer.
Removal of the ITBM will cause errors and it
may cause damage to the electrical system and
electronic modules of the vehicle. See an autho -
rized dealer if an aftermarket module is to be
installed.
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four-pin
and seven-pin wiring harness. Use a factory
approved trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the
vehicle but you must connect the harness to a
trailer connector. Refer to the following
illustrations.
NOTE:
Disconnect trailer wiring connector from the
vehicle before launching a boat (or any other
device plugged into vehicle’s electrical connect)
into water.
Be sure to reconnect once clear from water
area.

Shifting Into N (Neutral)
Use the following procedure to prepare your
vehicle for recreational towing.
1. Bring the vehicle to a complete stop on level
ground, with the engine running. Apply the
parking brake.
2. Press and hold the brake pedal. 3. Shift the transmission to NEUTRAL. The
driver's door must be closed (or the driver's
seat belt buckled) so that the transmission will
remain in NEUTRAL when the brake pedal is
released.
NOTE:If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.
4. Using a ballpoint pen or similar object, push and hold the recessed transfer case N
(Neutral) button (at the center of the transfer
case switches). The N (Neutral) indicator light
will illuminate, and remain lit, when the shift to
N (Neutral) is complete. After the shift is
completed and the N (Neutral) light stays on,
release the N (Neutral) 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 6 and 7 with the transmission in DRIVE.
9. Shift the transmission to NEUTRAL. 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. The transmission will automatically
select PARK when the engine is turned off. 10. Turn the ignition off.
11. Attach the vehicle to the tow vehicle using a
suitable tow bar.
12. Turn the ignition to the ON/RUN mode, but do not start the engine.
13. Release the parking brake.
14. Turn the ignition OFF.
NOTE:
Steps 2 and 3 are requirements that must be
met before pushing the N (Neutral) button, and
must continue to be met until the shift has been
completed. If any of these requirements are not
met before pushing the N (Neutral) button or are
no longer met during the shift, the N (Neutral)
indicator light will flash continuously until all
requirements are met or until the N (Neutral)
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 operable. 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 N (Neutral) position indicator light
indicates that shift requirements have not been
met.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (Neutral) position without first fully
engaging the parking brake. The transfer case N
(Neutral) position disengages both the front and
rear driveshafts from the powertrain and will
allow the vehicle to roll, even if the transmission
is in PARK. The parking brake should always be
applied when the driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain
that the transfer case is fully in N (Neutral)
before recreational towing to prevent damage to
internal parts.
