STARTING AND OPERATING153
(Continued)
(Continued)
SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver door is open. Once
manually bypassed, SafeHold will be enabled
again once the vehicle reaches 12 mph (20 km/h)
or the ignition is turned to the OFF position and
back to ON again.
Brake Service Mode
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs
for which you have the knowledge and the right
equipment. You should only enter Brake Service
Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push the
rear piston into the rear caliper bore. With the
Electric Park Brake (EPB) system, this can only be
done after retracting the EPB actuator.
Fortunately, actuator retraction can be done easily
by entering the Brake Service Mode through the
Uconnect Settings in your vehicle. This
menu-based system will guide you through the
steps necessary to retract the EPB actuator in
order to perform rear brake service.
Service Mode has requirements that must be met
in order to be activated:
The vehicle must be at a standstill.
The parking brake must be unapplied.
The transmission must be in PARK or NEUTRAL.
While in Service Mode, the EPB fault lamp will flash
continuously while the ignition is in ON/RUN.
When brake service work is complete, the following
steps must be followed to reset the park brake
system to normal operation:
Ensure the vehicle is at a standstill.
Press the brake pedal with moderate force.
Apply the EPB Switch.
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your vehicle
to a competent mechanic.
WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting 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.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
WARNING!

154STARTING AND OPERATING
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be in
PARK before the ignition can be turned to the OFF
position. This helps the driver avoid inadvertently
leaving the vehicle without placing the
transmission in PARK. This system also locks the
transmission in PARK whenever the ignition is in
the OFF position.
NOTE:The transmission is NOT locked in PARK when the
ignition is in the ACC position (even though the
engine will be off). Ensure that the transmission is
in PARK, and the ignition is OFF (not in ACC
position) before exiting the vehicle.
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI system that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must be
running and the brake pedal must be pressed.
The brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle
is stopped or moving at low speeds.
8-SPEED AUTOMATIC TRANSMISSION
Rotary Shifter — If Equipped
The transmission is controlled using a rotary
electronic gear selector located on the instrument
panel. The transmission gear range (PRND) is
displayed both above the gear selector and in the
instrument cluster. To select a gear range, simply
rotate the gear selector. You must press the brake
pedal to shift the transmission out of PARK (or
NEUTRAL, when the vehicle is stopped or moving at
low speeds). To shift past multiple gear ranges at
once (such as PARK to DRIVE), simply rotate the
gear selector to the appropriate detent. Select the
DRIVE range for normal driving.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle while
the engine is running. Before exiting a vehicle,
always come to a complete stop, then apply
the parking brake, shift the transmission into
PARK, and turn the ignition OFF. When the
ignition is in the OFF position, the transmis -
sion is locked in PARK, securing the vehicle
against unwanted movement.
When exiting the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock the vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the transmis -
sion gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition in the ACC or ON/RUN
position. A child could operate power
windows, other controls, or move the vehicle.
WARNING!CAUTION!
Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is above
idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.

STARTING AND OPERATING179
Adaptive Cruise Control (ACC) Operation
The buttons on the right side of the steering wheel
operate the Adaptive Cruise Control system.

Adaptive Cruise Control Buttons

Adaptive Cruise Control (ACC) Menu
The instrument cluster display will show the
current ACC system settings. The information it
displays depends on ACC system status.
Push the Adaptive Cruise Control (ACC) on/off
button until one of the following appears in the
instrument cluster display: Adaptive Cruise Control Off
When ACC is deactivated, the display will read
“Adaptive Cruise Control Off.”
Adaptive Cruise Control Ready
When ACC is activated, but the vehicle speed
setting has not been selected, the display will read
“Adaptive Cruise Control Ready.”
Adaptive Cruise Control Set
When the SET (+) or the SET (-) button is pushed,
the display will read “ACC SET.”
When ACC is set, the set speed will show in the
instrument cluster display.
The ACC screen may display once again if any of
the following ACC activity occurs:
System Cancel
Driver Override
System Off
ACC Proximity Warning
ACC Unavailable Warning
The instrument cluster display will return to the last
display selected after five seconds of no ACC
display activity.
Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is
20 mph (32 km/h).
When the system is turned on and in the ready
state, the instrument cluster display will read
“ACC Ready.”
When the system is off, the instrument cluster
display will read “Adaptive Cruise Control (ACC)
Off.”
NOTE:You cannot engage ACC under the following condi -
tions:
When in 4WD Low
When the brakes are applied
When the parking brake is applied
When the automatic transmission is in PARK,
REVERSE or NEUTRAL
When the vehicle speed is below the minimum
speed range
When the brakes are overheated
When the driver’s door is open at low speeds
When the driver’s seat belt is unbuckled at low
speeds
When there is a stationary vehicle in front of
your vehicle in close proximity
When Electronic Stability Control (ESC) Full Off
mode is active
1 — Distance Setting Increase
2 — Adaptive Cruise Control (ACC) On/Off
3 — Distance Setting Decrease

22_DT_OM_EN_USC_t.book Page 179

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.
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

22_DT_OM_EN_USC_t.book Page 182

STARTING AND OPERATING183
NOTE:
The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action and
does not 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
In the event that the ACC system brings your
vehicle to a standstill while following the vehicle in
front, if the vehicle in front starts moving within two
seconds of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
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 stand -
still for approximately three consecutive minutes, the parking brake will be activated, and the ACC
system will be canceled.
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 canceled.
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 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. 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 and
snow, or tunnels with reflective tiles). The ACC
system will recover after the vehicle has left these
areas. Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active, Fixed Speed Cruise
Control is still available.
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
in the camera in the center of the windshield, on
the forward side of the rearview mirror.
To keep the ACC system operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully clear
the windshield.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc
-
tion or failure and require a sensor realignment.
Do not attach or install any accessories near the
sensor, including transparent material. Doing so
could cause an ACC system failure or malfunc -
tion.
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.

STARTING AND OPERATING185
TOWING A TRAILER
ACC while towing a trailer is recommended only
with an Integrated Trailer Brake Controller.
Aftermarket trailer brake controllers will not
activate the trailer brakes when ACC is braking.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that
is offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be
sufficient distance to the vehicle ahead. The offset
vehicle may move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS
When driving on a curve with ACC engaged, the
system may increase or decrease the vehicle
speed for stability, with no vehicle ahead detected.
Once the vehicle is out of the curve, the system will
resume your original set speed. This is a part of
normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
USING ACC ON HILLS
ACC performance may be limited when driving on
hills. ACC may not detect a vehicle in your lane
depending on the speed, vehicle load, traffic
conditions, and the steepness of the hill.
ACC Hill Example

LANE CHANGING
ACC may not detect a vehicle until it is completely
in the lane in which you are traveling. In the lane
changing example below, ACC has not yet detected
the vehicle changing lanes and it may not detect
the vehicle until it's too late for the ACC system to
take action. ACC may not detect a vehicle until it is
completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be
attentive and ready to apply the brakes if
necessary.
Lane Changing Example

22_DT_OM_EN_USC_t.book Page 185

186STARTING AND OPERATING
NARROW VEHICLES
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the lane.
There may not be sufficient distance to the vehicle
ahead.

Narrow Vehicle Example

STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or
vehicles. For example, ACC will not react in
situations where the vehicle you are following exits
your lane and the vehicle ahead is stopped in your
lane. It will consider this stopped vehicle a stationary object as it did not previously detect
movement from it. Always be attentive and ready
to apply the brakes if necessary.

Stationary Object And Stationary Vehicle Example

PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear and/or front fascia/bumper and a
detected obstacle when backing up or moving
forward (e.g. during a parking maneuver). If your
vehicle is equipped with the automatic braking
function, the vehicle brakes may be automatically
applied and released when the vehicle is in
REVERSE if the system detects a possible collision
with an obstacle.
NOTE:
The driver can disable the automatic braking
function by turning ParkSense off via the Park -
Sense switch. The driver can also override auto -
matic braking by changing the gear or by
pressing the gas pedal over 90% of its capacity
during the braking event.
Automatic brakes will not be available if the
vehicle is in 4WD Low.
Automatic brakes will not be available if there is
a fault in the brake module.
Automatic brakes will not be available if there is
a faulted condition detected with the ParkSense
Park Assist system or the Braking System.
The automatic braking function may only be
applied if the vehicle deceleration is not enough
to avoid colliding with a detected obstacle.
The automatic braking function may not be
applied fast enough for obstacles that move
toward the rear of the vehicle from the left and/
or right sides.
The automatic braking function can be
enabled/disabled from the Customer Program -
mable Features section of the Uconnect system.

22_DT_OM_EN_USC_t.book Page 186

STARTING AND OPERATING191
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear fascias/bumpers
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Park -
Sense.
When you turn Front or Rear ParkSense off, the
instrument cluster display will show a vehicle
graphic of the Front or Rear ParkSense on/off
state for two seconds. Furthermore, once you
turn Front or Rear ParkSense off, it remains off
until you turn it on again, even if you cycle the
ignition.
When you move the gear selector to the
REVERSE position and Front or Rear ParkSense
is turned off, the instrument cluster display will
show a vehicle graphic with "OFF" in the corre -
sponding side. This vehicle graphic will be
displayed for as long as the vehicle is in
REVERSE.
ParkSense, when on, will reduce the volume of
the radio when it is sounding a tone.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so can
result in the system not working properly. The
ParkSense system might not detect an obstacle
behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle
is behind or in front of the fascia/bumper.
Use the ParkSense switch to turn the ParkSense
system off if obstacles such as bicycle carriers,
trailer hitches, etc. are placed near the rear
fascia/bumper. Failure to do so can result in the
system misinterpreting a close obstacle as a
sensor problem, causing the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message to
be appear in the instrument cluster display.
ParkSense should be disabled when the tailgate
is in the lowered or open position. A lowered tail -
gate could provide a false indication that an
obstacle is behind the vehicle and could also
cause a false braking event.
The Rear ParkSense system will automatically
disable when the system detects that a trailer
with trailer brakes has been connected to the
Integrated Trailer Brake Module.
The Front ParkSense system will automatically
disable if a snow plow has been connected to
the vehicle.
WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and
must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.
Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
assembly be disconnected from the vehicle
when the vehicle is not used for towing.
Failure to do so can result in injury or damage
to vehicles or obstacles because the hitch ball
will be much closer to the obstacle than the
rear fascia/bumper when the vehicle sounds
the continuous tone. Also, the sensors could
detect the ball mount and hitch ball assembly,
depending on its size and shape, and give a
false indication that an obstacle is behind the
vehicle, and could cause false braking.
