STARTING AND OPERATING177
To Set A Desired Speed
Turn the Cruise Control on.
When the vehicle has reached the desired speed,
push the SET (+) or SET (-) button and release.
Release the accelerator and the vehicle will
operate at the selected speed.
NOTE:The vehicle should be traveling at a steady speed
and on level ground before pushing the SET (+) or
SET (-) button.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display. Metric Speed (km/h)
Pushing the SET (+)
, or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) or SET (-)
button, the new set speed will be the current speed
of the vehicle.
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, pushing the CANC
(cancel) button, or normal brake pressure while
slowing the vehicle will deactivate the Cruise
Control system without erasing the set speed from
memory.
The following conditions will also deactivate the
Cruise Control system without erasing the set
speed from memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.

178STARTING AND OPERATING
(Continued)
Pushing the on/off button or placing the ignition in
the OFF position, erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently
Ú page 176.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or acceleration (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 480.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead; and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention 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 condi -
tions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
Will bring your vehicle to a complete stop
while following a vehicle ahead and hold
your vehicle for approximately three
minutes in the stop position. If the vehicle
ahead does not start moving within three
minutes the parking brake will be acti -
vated, and the ACC system will be
cancelled.
You should switch off the ACC system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa -
tions (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!

22_DT_OM_EN_USC_t.book Page 178

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.

3. Insert the fuel nozzle fully into the filler pipe – the nozzle opens and holds the flapper door
while refueling.
4. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off, the fuel tank is full.
5. Remove the fuel nozzle and close the fuel door.
AVOID USING CONTAMINATED FUEL
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel system.
Proper maintenance of the engine fuel filter and
fuel tank is essential Ú page 408.
WARNING!
Always place container on the ground before
filling.
Keep the pump nozzle in contact with the
container when you are filling it.
Use only approved containers for flammable
liquid.
Do not leave container unattended while
filling.
A static electric charge could cause a spark
and fire hazard.

2 — Diesel Fuel Fill Location
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light (MIL) to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

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.

Four-Pin Connector

WARNING!
Connecting a trailer that is not compatible with
the ITBM system may result in reduced or
complete loss of trailer braking. There may be a
increase in stopping distance or trailer instability
which could result in personal injury.
CAUTION!
Connecting a trailer that is not compatible with
the ITBM system may result in reduced or
complete loss of trailer braking. There may be a

STARTING AND OPERATING225
TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, select
TOW/HAUL mode or select a lower gear range
(using the Electronic Range Select (ERS) shift
control).
NOTE:Using TOW/HAUL mode or selecting a lower gear
range (using the ERS shift control) while operating
the vehicle under heavy loading conditions will
improve performance and extend transmission life
by reducing excessive shifting and heat build up.
This action will also provide better engine braking.
Tow/Haul Mode
To reduce potential for automatic transmission
overheating, activate TOW/HAUL mode when
driving in hilly areas, or select a lower gear range
(using the (ERS) shift control) on more severe
grades.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.
Air Suspension System
To aid in attaching/detaching the trailer from the
vehicle, the air suspension system can be used
Úpage 165. Selecting Tow/Haul or connecting a
trailer with an Integrated Trailer Brake Module
(ITBM) will disable Automatic Aero mode to avoid
height changes while towing and shifting loads or
tongue weights.
NOTE:The vehicle must remain in the engine running
position while attaching a trailer for proper leveling
of the air suspension system.
SNOWPLOW
Snowplow Prep Packages are available as a factory
installed option. These packages include
components necessary to equip your vehicle with a
snowplow.
NOTE:Before installation of a snowplow it is highly recom -
mended that the owner/installer obtain and follow
the recommendations contained within the current
Body Builder’s Guide. See an authorized dealer,
installer or snowplow manufacturer for this infor -
mation. There are unique electrical systems that
must be connected to properly ensure operator
safety and prevent overloading vehicle systems.
WARNING!
Attaching a snowplow to this vehicle could
adversely affect performance of the airbag
system in a collision. Do not expect that the
airbag will perform as described earlier in this
manual.
CAUTION!
The “Lamp Out” indicator could illuminate if
exterior lamps are not properly installed.

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.

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.

requirements are not met before pushing the
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 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.
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.).

STARTING AND OPERATING231
(Continued)
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 Water
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following
Cautions and Warnings 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.
CAUTION!
Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom
of the tire rims mounted on the vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when driving through standing water. This will minimize
wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is milky
or foamy in appearance) after driving through
standing water. Do not continue to operate
the vehicle if any fluid appears contaminated,
as this may result in further damage. Such
damage is not covered by the New Vehicle
Limited Warranty.
Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause
serious internal damage to the engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
CAUTION!
