AXLE LOCK SYSTEM — IF EQUIPPED
This vehicle is equipped with an electronically
locking rear differential. When engaged, this
differential locks the axle shafts forcing the wheels
to spin at an equal rate. The locking of the rear
differential should only be engaged during
low-speed, extreme off-road situations where one
wheel is likely to not be in contact with the ground.
It is not recommended to drive the vehicle with the
differentials locked on pavement due to the
reduced ability to turn and speed limitations.

AXLE LOCK Button
The locking rear axle is controlled by the AXLE
LOCK button.
Under normal driving conditions, the rear axle
should be unlocked.
During the command to lock the rear axle, the
indicator light will flash until the axle is locked.
After the lock command has been successfully
executed, the light will remain on solid.
Operating in 4WD LOW the locker can be engaged
up to 40 mph (64 km/h) and will remain engaged
throughout the 4WD LOW speed range.
CAUTION!
Do not lock the rear axle on hard surfaced
roads. The ability to steer the vehicle is
reduced and damage to the drivetrain may
occur when the axle is locked on hard
surfaced roads.
Do not try to lock the rear axle if the vehicle is
stuck and the tires are spinning. You can
damage drivetrain components. Lock the rear
axle before attempting situations or navi
-
gating terrain, which could possibly cause the
vehicle to become stuck.

22_DT_OM_EN_USC_t.book Page 172

STARTING AND OPERATING173
Operating the locker in 2WD, 4WD AUTO, and
4WD LOCK/HIGH, the locker can be engaged up to
20 mph (32 km/h). While driving with the locker
engaged, if speed exceeds 25 mph (40 km/h), the
locker will automatically disengage, but will
automatically re-engage at 20 mph (32 km/h).
NOTE:Left to right wheel speed difference may be
necessary to allow the rear axle to fully lock. If the
indicator light is flashing after selecting the rear
axle lock mode, drive the vehicle in a turn or on
loose gravel to expedite the locking action.
The axle locker could become torque locked due to
side to side loads on the rear axle. Driving slowly
while turning the steering wheel from a left hand
turn to a right hand turn or driving in REVERSE for
a short distance may be required to release the
torque lock and unlock the axles.
To unlock the rear axle, push the AXLE LOCK
button. The AXLE LOCK indicator light will go out
when the rear axle is unlocked.
LIMITED-SLIP DIFFERENTIAL —
IF EQUIPPED
The limited-slip differential provides additional
traction on snow, ice, mud, sand and gravel,
particularly when there is a difference between the
traction characteristics of the surface under the
right and left rear wheels. During normal driving and cornering, the limited-slip unit performs
similarly to a conventional differential. On slippery
surfaces, however, the differential delivers more of
the driving effort to the rear wheel having the
better traction.
The limited-slip differential is especially helpful
during slippery driving conditions. With both rear
wheels on a slippery surface, a slight application of
the accelerator will supply maximum traction.
When starting with only one rear wheel on an
excessively slippery surface, slight momentary
application of the parking brake may be necessary
to gain maximum traction.
Care should be taken to avoid sudden
accelerations when both rear wheels are on a
slippery surface. This could cause both rear wheels
to spin, and allow the vehicle to slide sideways on
the crowned surface of a road or in a turn.
POWER STEERING
ELECTRIC POWER STEERING
The electric power steering system will provide
increased vehicle response and ease of
maneuverability. The power steering system
adapts to different driving conditions.
If the steering icon is flashing, it indicates that the
vehicle needs to be taken to the dealer for service.
It is likely the vehicle has lost power steering
assistance.
If the steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is
displayed on the instrument cluster screen, this
indicates an over temperature condition in the
power steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few
moments until the icon and message turn off
Ú
page 114.
If the steering icon is displayed and the “SERVICE
POWER STEERING – ASSIST OFF” message is
displayed on the instrument cluster screen, this
indicates the vehicle needs to be taken to the
dealer for service Ú page 114.
WARNING!
When servicing vehicles equipped with a
limited-slip or locking differential, never run the
engine with one rear wheel off the ground as the
vehicle may drive through the rear wheel
remaining on the ground and result in
unintended movement.

180STARTING AND OPERATING
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 display will show “Adaptive
Cruise Control (ACC) Off.”
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 show
the set speed.
NOTE:Fixed Speed Cruise Control can be used without
ACC enabled. To change between the different
modes, push the ACC on/off button which turns
the ACC and the Fixed Speed Cruise Control off. Pushing the Fixed Speed Cruise Control on/off
button will result in turning on (changing to) Fixed
Speed Cruise Control mode.
If ACC is set when the vehicle speed is
below
20 mph (32 km/h), the set speed will default to
20 mph (32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below
20 mph (32 km/h).
If either 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:
Keeping your foot on the accelerator pedal can
cause the vehicle to continue to accelerate
beyond the set speed. If this occurs, the
message “ACC DRIVER OVERRIDE” will display
in the instrument cluster display.
If you continue to accelerate beyond the set
speed while ACC is enabled, the system will not
control the distance between your vehicle and
the vehicle ahead. The vehicle speed will only be
determined by the position of the accelerator
pedal.
To Cancel
The following conditions cancel the ACC or Fixed
Speed Cruise Control systems:
The brake pedal is applied
The CANC (cancel) button is pushed
The Anti-Lock Brake system (ABS) activates
The trailer brake is applied manually (if
equipped)
The gear selector is removed from the DRIVE
position
The Electronic Stability Control/Traction Control
System (ESC/TCS) activates
The vehicle parking brake is applied
The Trailer Sway Control (TSC) activates
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.
WARNING!
In the Fixed Speed Cruise Control mode, the
system will not react to vehicles ahead. In
addition, the proximity warning does not activate
and no alarm will sound even if you are too close
to the vehicle ahead since neither the presence
of the vehicle ahead nor the vehicle-to-vehicle
distance is detected. Be sure to maintain a safe
distance between your vehicle and the vehicle
ahead. Always be aware which mode is selected.

22_DT_OM_EN_USC_t.book Page 180

184STARTING AND OPERATING
When the condition that deactivated the system is
no longer present, the system will return to the
“Adaptive Cruise Control Off” state and will resume
function by simply reactivating it.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and a chime will
sound when conditions temporarily limit system
performance. This most often occurs at times of
poor visibility, such as in snow or heavy rain and
fog. The ACC system may also become temporarily
blinded due to obstructions, such as mud, dirt, or
ice on windshield, driving directly into the sun and
fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/FCW
Limited Functionality Clean Front Windshield” and
the system will have degraded performance. This message can sometimes be displayed while
driving in adverse weather conditions. The ACC/
FCW system will recover after the vehicle has left
these areas. Under rare conditions, when the
camera is not tracking any vehicles or objects in its
path this warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rear view
mirror. They may require cleaning or removal of an
obstruction.
When the condition that created limited
functionality is no longer present, the system will
return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean Front
Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the windshield and
forward facing camera inspected at an authorized
dealer.
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service Required”
or “Cruise/FCW Unavailable Service Required”,
there may be an internal system fault or a
temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable under normal conditions, ACC will be temporarily
unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem
persists, see an authorized dealer.
Precautions While Driving With ACC
NOTE:
Aftermarket add-ons such as snow plows, lift
kits, and brush/grille bars can hinder module
performance. Ensure the radar/camera has no
obstructions in the field of view.
Height modifications can limit module perfor
-
mance and functionality.
Do not put stickers or easy passes over the
camera/radar field of view.
Any modifications to the vehicle that may
obstruct the field of view of the radar/camera
are not recommended.
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
