174STARTING AND OPERATING
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service.
FUEL SAVER TECHNOLOGY 5.7L ENGINES
ONLY — IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function, included with eTorque
equipped vehicles, is developed to save fuel and
reduce emissions. The system will stop the engine
automatically as the vehicle decelerates at low
speeds if the required conditions are met. Releasing the brake pedal or shifting out of DRIVE
will automatically restart the engine.
Vehicles equipped with eTorque contain a
heavy-duty motor generator and an additional
hybrid electric battery to store energy from vehicle
deceleration used to expand engine off energy
storage and for engine startup after a stop, as well
as providing engine torque assist when conditions
are met to enable this.
AUTOSTOP MODE
The Stop/Start feature is enabled after every
normal customer engine start. It will remain in
STOP/START NOT READY until you drive forward
with a vehicle speed greater than 2 mph (3 km/h).
At that time, the system will go into STOP/START
READY and if all other conditions are met, the
system may go into STOP/START AUTOSTOP
ACTIVE Autostop mode.
To Activate The Autostop Mode, The Following
Must Occur:

1. The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster within the
Stop/Start section
Ú
page 114.

2. The vehicle must be decelerating and likely coming to a complete stop.
3. The transmission gear selector must be in DRIVE and the brake pedal pressed. The engine will shut down, the tachometer will
move to the zero position and the stop/start
telltale will illuminate indicating you are in an
Autostop. While in an Autostop, the Climate
Controls system may automatically adjust airflow
to maintain cabin comfort. Customer settings will
be maintained upon return to an engine running
condition.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check
many safety and comfort conditions to see if they
are fulfilled. In following situations, the engine will
not Autostop:
Driver’s seat belt is not buckled
Driver’s door is not closed
The vehicle is on a steep grade
Cabin heating or cooling is in process and an
acceptable cabin temperature has not been
achieved
HVAC is set to full defrost mode at a high blower
speed
Engine has not reached normal operating
temperature
Engine or exhaust temperature is too high
The battery is charging

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.

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 OPERATING187
ParkSense will retain its last known configura -
tion state for the automatic braking function
through ignition cycles.
Trailer hitch ball assembly may cause false
braking events if left attached after towing.
The automatic braking function is intended to
assist the driver in avoiding possible collisions with
detected obstacles when backing up in REVERSE
gear.
NOTE:
The system is provided to assist the driver and
not to substitute the driver.
The driver must stay in full control of the
vehicle's acceleration and braking and is
responsible for the vehicle's movements.
For limitations of this system and usage
precautions, see Ú page 191.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is placed in the ON/RUN position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled while in one of these gears, the system will
remain active until the vehicle speed is increased
to approximately 7 mph (11 km/h) or above. A
warning will appear in the instrument cluster
display indicating the vehicle speed is above ParkSense operating speed while in REVERSE. The
system will become active again if the vehicle
speed is decreased to speeds less than
approximately 6 mph (9 km/h).
PARKSENSE SENSORS
The four ParkSense sensors (six if equipped with
Active Parksense), located in the front fascia/
bumper, monitor the area in front of the vehicle
that is within the sensors’ field of view, and the four
ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that
is within the sensors’ field of view. The front
sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
the front fascia/bumper. The rear sensors can
detect obstacles from approximately 12 inches
(30 cm) up to 79 inches (200 cm). These distances
depend on the location, type and orientation of the
obstacle in the horizontal direction.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within
the instrument cluster display Ú
page 114. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle.
PARKSENSE DISPLAY
The warning display will turn on indicating the
system status when the vehicle is in REVERSE or
when the vehicle is in DRIVE and an obstacle has
been detected.
The system will indicate a detected obstacle by
showing a single arc in the left, right, or center
regions based on the obstacle’s distance and
location relative to the vehicle.
If an obstacle is detected in the center front region,
the display will show a single solid arc in the center
front region with no chime. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and a fast
chime will be heard and will change from fast to
continuous.
If an obstacle is detected in the left and/or right
front region, the display will show a single flashing
arc in the left and/or right front region and will
produce a fast chime. As the vehicle moves closer
to the obstacle, the display will show the single arc
moving closer to the vehicle and the tone will
change from fast to continuous.

192STARTING AND OPERATING

PARKSENSE ACTIVE PARK ASSIST SYSTEM —
IF EQUIPPED

The ParkSense Active Park Assist system is
intended to assist the driver during parallel and
perpendicular parking maneuvers by identifying a
proper parking space, providing audible/visual
instructions through the instrument cluster
display, and controlling the steering wheel. The
ParkSense Active Park Assist system is defined as
“semi-automatic” since the driver maintains
control of the accelerator, gear selector and brakes. Depending on the driver's parking
maneuver selection, the ParkSense Active Park
Assist system is capable of maneuvering a vehicle
into a parallel or a perpendicular parking space on
either side (i.e., driver side or passenger side).
NOTE:
The driver is always responsible for controlling
the vehicle, responsible for any surrounding
objects, and must intervene as required.
The system is provided to assist the driver and
not to substitute the driver.
During a semi-automatic maneuver, if the driver
touches the steering wheel after being
instructed to remove their hands from the
steering wheel, the system will cancel, and the
driver will be required to manually complete the
parking maneuver.
The system may not work in all conditions (e.g.
environmental conditions such as heavy rain,
snow, etc., or if searching for a parking space
that has surfaces that will absorb the ultrasonic
sensor waves).
New vehicles from the dealership must have at
least 30 miles (48 km) accumulated before the
ParkSense Active Park Assist system is fully cali
-
brated and performs accurately. This is due to
the system’s dynamic vehicle calibration to
improve the performance of the feature.
The driver must control the vehicle’s brakes.
The automatic emergency braking feature is
NOT intended to substitute for the driver during
REVERSE maneuvers.
ENABLING AND DISABLING THE
P

To enable or disable the ParkSense Active Park
Assist system, push the ParkSense Active Park
Assist switch once (LED turns on). Pushing the
switch a second time will disable the system
(LED turns off).
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sensors
will not be detected when they are in close
proximity.
The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom -
mended that the driver looks over his/her
shoulder when using ParkSense.

22_DT_OM_EN_USC_t.book Page 193

194STARTING AND OPERATING

Press OK to Switch to Parallel Park

NOTE:
When searching for a parking space, use the
turn signal indicator to select which side of the
vehicle you want to perform the parking
maneuver. The ParkSense Active Park Assist
system will automatically search for a parking
space on the passenger's side of the vehicle if
the turn signal is not activated.
The driver needs to make sure that the selected
parking space for the maneuver remains free
and clear of any obstructions (e.g. pedestrians,
bicycles, etc.).
The driver is responsible to ensure that the
selected parking space is suitable for the
maneuver and free/clear of anything that may
be overhanging or protruding into the parking
space (e.g., ladders, tailgates, etc. from
surrounding objects/vehicles).
When searching for a parking space, the driver
should drive as parallel or perpendicular
(depending on the type of maneuver) to other
vehicles as possible.
The feature will only indicate the last detected
parking space (example: if passing multiple
available parking spaces, the system will only
indicate the last detected parking space for the
maneuver). A parking space is considered
invalid after the vehicle is 32 ft (10 m) or more
away from it. When an available parking space has been found,
and the vehicle is not in position, you will be
instructed to move forward to position the vehicle
for a perpendicular or parallel parking sequence
(depending on the type of maneuver being
performed).

Space Found — Keep Moving Forward

Once the vehicle is in position, you will be
instructed to stop the vehicle’s movement and
remove your hands from the steering wheel. When
the vehicle comes to a standstill (your hands still
removed from the steering wheel), you will be
instructed to place the gear selector into the
REVERSE position.
