CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL
When engaged, the Cruise Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h).
The Cruise Control buttons are located on the right
side of the steering wheel.
Cruise Control Buttons
To Activate
Push the on/off button to activate the Cruise
Control. The cruise indicator light in the instrument
cluster display will illuminate. To turn the system
off, push the on/off button a second time. The
cruise indicator light will turn off. The system
should be turned off when not in use.
1 — SET (+)/Accel
2 — CANC/Cancel
3 — SET (-)/Decel
4 — On/Off
5 — RES/Resume
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.
WARNING!
Leaving the Cruise Control 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 an
accident. Always ensure the system is off when
you are not using it.

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.

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.

Trailer Memory
The trailer steering system will automatically retain
the calibration of the previous five trailers
connected, so recalibration will not be necessary
when hooking up. The next time the vehicle is
started, place the vehicle in DRIVE and drive a
short distance. The TRSC system can then be
activated.
NOTE:Trailers may look different during day and night
conditions. In such cases, the trailer may need to
recalibrate. Some trailers (such as boat trailers) will need to
recalibrate while loaded and unloaded.
NOTE:
The system may not detect a trailer in low light
conditions. In sunny conditions, the perfor
-
mance may be degraded as shadows pass over
the trailer.
The driver is always responsible for safe opera -
tion of truck and trailer.
The driver is always in control of the truck as
well as the trailer and is responsible for
controlling the throttle and brakes.
The system may not function when the camera
lens is blocked, blurred (covered with water,
snow, ice, dirt, etc) and will not work unless the
tailgate is upright and fully latched.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The engine, axle or other parts could be
damaged.
