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
conditions.
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 activated, and the ACC system
will be cancelled.

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
increments until the button is released. The
new set speed is reflected in the instrument
cluster display.
NOTE:
When you override and push the SET (+) button
or SET (-) buttons, the new set speed will be the
current speed of the vehicle.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming
a set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to
follow these warnings can result in a collision
and death or serious personal injury.

184STARTING AND OPERATING
When An ACC Distance Is Also Set:
When you use the SET (-) button to decel -
erate, 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 main -
tain set speed. When driving uphill and down -
hill, the ACC system will cancel if the braking
temperature exceeds normal range (over -
heated).
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.
1 — Longest Distance Setting (Four Bars)
2 — Long Distance Setting (Three Bars)
3 — Medium Distance Setting (Two Bars)
4 — Short Distance Setting (One Bar)

21_DT_OM_EN_USC_t.book Page 184

STARTING AND OPERATING185
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.
NOTE:
The “BRAKE!” Screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the
Forward Collision Warning system is applying
the brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC)
engaged, and following a vehicle, the system
will provide an additional acceleration up to the
ACC set speed to assist in passing the vehicle. This additional acceleration is triggered when
the driver utilizes the left turn signal and will
only be active when passing on the left hand
side.
ACC Operation At Stop
If the ACC system brings your vehicle to a
standstill while following the vehicle in front,
your vehicle will resume motion without any
diver intervention if the vehicle in front starts
moving within two seconds.
If the vehicle in front does not start moving
within two seconds of your vehicle coming to a
standstill, 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.
NOTE:
After the ACC system holds your vehicle at a
standstill for approximately three consecutive
minutes, the parking brake will be activated,
and the ACC system will be cancelled.
While ACC is holding your vehicle at a standstill,
if the driver seat belt is unbuckled or the driver
door is opened, the parking brake will be
activated, and the ACC system will be cancelled.
Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning will display and also a chime
will indicate when conditions temporarily limit
system performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will display
“ACC/FCW Unavailable Wipe Front Radar
Sensor” and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” message can sometimes be displayed
while driving in highly reflective areas (i.e. ice
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in
a collision and death or serious personal
injury.

TRAILER AND TONGUE WEIGHT

Weight Distribution

Consider the following items when computing
the weight on the rear axle of the vehicle:
The tongue weight of the trailer.
The weight of any other type of cargo or
equipment put in or on your vehicle.
The weight of the driver and all passengers.
NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options or
dealer-installed options must be considered as
part of the total load on your vehicle. Refer to
the “Tire And Loading Information” placard for the maximum combined weight of occupants
and cargo for your vehicle.
TRAILER REVERSE STEERING CONTROL
Trailer Reverse Steering Control (TRSC) is a
feature that will allow the driver to back up a
trailer using a knob located on the center stack.
The feature works by the user first hooking up a
trailer and then performing the calibration
maneuvers.
Calibration:
First bring the vehicle and trailer to a complete
stop in a large open area, place the vehicle in
PARK and push the TRSC button located above
the knob in the center stack.
To calibrate a trailer, the driver must drive
forward 100 ft (30 m). Then perform a 90
degree turn and return to a straight position for
65 ft (20 m). Perform another 90 degree turn,
followed by another 65 ft (20 m) straight drive. Upon completion this the feature will be
available to activate.
NOTE:
The 90 degree turns could be in either the left
or right direction.

Trailer Reverse Steering Control Calibration

CAUTION!
Always observe the position of the trailer and
surroundings using the camera and mirrors to
avoid damage to the truck or trailer.
1 — Straight 100 ft (30 m)
2 — Intersection turn with radius 50-65 ft
(15-20 m) in either direction
3 — Straight 50 ft (15 m)
4 — Intersection turn with radius 50-65 ft
(15-20 m) in either direction
5 — Straight 50 ft (15 m)
6 — Straight 65 ft (20 m), making sure to align ve -
hicle/trailer to path center line
7 — Feature is active, turn knob left or right to
back the trailer up

21_DT_OM_EN_USC_t.book Page 219

220STARTING AND OPERATING
Once calibrated the driver can shift to PARK,
push the button on top of the TRSC knob and
activate the feature. The knob is then turned
either to the left or right depending on what
direction the driver wants the trailer to go.

Trailer Reverse Steering Control Knob

NOTE:
When steering the trailer with the knob, remove
hands from the steering wheel.
There is also a holdover state where if during an
active trailer steering maneuver, the driver
shifts to NEURAL or DRIVE to straighten the
trailer, the driver may shift back to REVERSE
and not need to reactivate the feature. However
the feature will cancel after 10 seconds or when
the vehicle speed reaches 8 mph (12 km/h). Instrument Cluster Messages:
“Drive forward to calibrate trailer” will display
when a trailer is not calibrated and the
vehicle is at standstill while the button is
pushed.
“Calibrating trailer” will display when the
trailer is not calibrated and the vehicle is
moving while the button is pushed.
“To activate trailer steering shift to P” will
display when the trailer is calibrated success
-
fully and the vehicle is not in PARK.
“Trailer Steering ready, shift to reverse” will
display when the button is pushed, trailer is
calibrated and the vehicle is in PARK.
“Trailer steering active” will display after the
driver shifts to REVERSE and indicates the
feature is active.
“Trailer Steering Unavailable” will display if
there is a fault in the system preventing acti -
vation, the driver’s door is open, the driver’s
seat belt is unbuckled, or the tailgate is open. Other reasons the feature may cancel:
The driver overrides steering by placing
hands on the steering wheel.
Trailer tracking is lost.
If the trailer angle becomes excessive, the
brakes apply bringing the vehicle to a stop
and then applying the parking brake.
Trailer steering button is pushed while active.
Vehicle speed goes over 8 mph (12 km/h).
Driver door is open and seat belt is
unbuckled.
Transmission shifted to PARK.
Trailer Memory
The trailer steering system can remember up to
five trailers, so recalibration will not be
necessary.
To store a trailer to memory, calibrate the trailer
and then allow the vehicle to be off for a period
of time. The next time the vehicle is started,
place the vehicle in DRIVE and drive a short
distance. The trailer system can then be
activated.
