Adaptive Cruise Control Buttons (If Equipped)
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 condi -
tions 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.
You should not utilize 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.

Ú
page 93.

To Set A Desired Speed
When the vehicle reaches the speed desired, push
the SET (+) button or the SET (-) button and
release. The instrument cluster display will show
the set speed.
NOTE:Fixed Speed Cruise Control can be used without
ACC enabled. To change between the different
modes, push the ACC on/off button which turns
the ACC and the Fixed Speed Cruise Control off.
Pushing the Fixed Speed Cruise Control on/off
button will result in turning on (changing to)
Fixed Speed Cruise Control mode.
If ACC is set when the vehicle speed is below
20 mph (32 km/h), the set speed will default to
20 mph (32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below
20 mph (32 km/h). If either system is set when the vehicle speed is
above
20 mph (32 km/h), the set speed shall be
the current speed of the vehicle.
NOTE:
Keeping your foot on the accelerator pedal can
cause the vehicle to continue to accelerate
beyond the set speed. If this occurs, the Adap -
tive cruise control light will flash and, if a target
is detected by the sensor, the target graphics
will also flash.
If you continue to accelerate beyond the set
speed while ACC is enabled, the system will not
be controlling the distance between your vehicle
and the vehicle ahead. The vehicle speed will
only be determined by the position of the accel-
erator pedal.
Desired Driving Speed Through A Detected
Speed Sign
The Active Driving Assist (ADA) system allows the
driver to set the detected speed sign Úpage 98 as
the new desired driving speed. The Traffic Sign
Assist (TSA) system will suggest the new detected
speed sign on the cluster and then the driver can
decide to confirm the speed sign capturing by
pressing the RES (resume) button.
WARNING!
Leaving the Adaptive Cruise Control (ACC)
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 a collision. Always leave the system off
when you are not using it.
WARNING!
In Fixed Speed Cruise Control mode (ACC not
enabled), the system will not react to vehicles
ahead. In addition, the proximity warning does
not activate and no alarm will sound even if you
are too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be sure
to maintain a safe distance between your vehicle
and the vehicle ahead. Always be aware which
mode is selected.

the RES (resume) button, or apply the acceler
-
ator pedal to reengage the Adaptive Cruise
Control (ACC) to the existing set speed.
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
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 increments 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 (-) button, 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.

STARTING AND OPERATING95
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 a 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 tries to leave the vehicle, the parking
brake will be activated and the ACC system will be
canceled.
Display Warnings And Maintenance
RADAR SENSOR UNAVAILABILITY WARNING
The “ACC Front Radar Sensor Temporarily Blinded”
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
this warning message and the system will
deactivate.
This 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 Front Radar Sensor Temporarily
Blinded” warning is active, Fixed Speed Cruise
Control can be still enabled.
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 center of the vehicle behind the lower grille.
To keep the ACC system operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc -
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an authorized
dealer for service.
Do not attach or install any accessories near the
sensor, including transparent material or after -
market grilles. Doing so could cause an ACC
system failure or malfunction.
When the condition that deactivated the system is
no longer present, the system will return to the
“Adaptive Cruise Control Off” state and will resume
function by simply reactivating it.
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.

100STARTING AND OPERATING
ACTIVE DRIVING ASSIST SYSTEM —
IF EQUIPPED
OPERATION
The Active Driving Assist (ADA) system is combined
with the Adaptive Cruise Control (ACC) system,
and centers the vehicle in the driving lane while
traveling at speeds up to 93 mph (150 km/h).
For ACC system operating instructions and system
limitations, see Úpage 89.
NOTE:
The driver should always obey traffic laws and
speed limits. Never drive above applicable
speed limit restrictions.
The driver can override ADA at any time by
braking, accelerating, or steering the vehicle.
Just like ACC, ADA will maintain a set speed as long
as the set distance between your vehicle and the
vehicle in front is maintained. ADA will also keep
your vehicle centered between the lane lines, and
monitor for other vehicles in adjacent lanes by
utilizing the Blind Spot Monitoring sensors.
ADA uses sensors within the steering wheel to
monitor driver attentiveness. ADA requires the
driver’s hands on the steering wheel at all times.
The system will generally aim to keep the vehicle
centered in the lane, but when the driver turns the
steering wheel (e.g. to move farther away from a
large vehicle in the next lane) the system will
reduce its control and enter "co-steering" mode.
While in co-steering mode, the system will provide
reduced assistance and allow the driver to control
the path of the vehicle. Once the driver stops
providing input to the steering wheel, the system
will require a few seconds to fully resume lane
centering assistance, especially during curves.
Do not place any objects on the steering wheel
(e.g. steering wheel covers) which could inter -
fere with the hand detection sensors.
Always pay attention to the road when using
the Active Driving Assist system. ADA will not
steer to avoid safety hazards, construction
zones, objects, or roadway impediments.
You need to maintain control to steer and
brake the vehicle in such situations and when
merging into traffic, entering the highway,
making a turn for crossing traffic, or stopping
for traffic control devices.
WARNING!WARNING!

The Active Driving Assist (ADA) system is a
convenience system. It is not a substitute for
active driver involvement. It is always the driver’s
responsibility to be attentive of road traffic, weather
conditions, vehicle speed, distance to the vehicle
ahead, position in the lane compared to other
vehicles, and brake operation to ensure safe
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.

You should not utilize the ADA system:
When driving in complex driving situations
(e.g. urban environments, construction zones,
etc.), adverse weather or low visibility condi -
tions (e.g. rain, snow, fog, sleet, dust), or
adverse road conditions (e.g. heavy traffic,
worn or missing lane markings, etc.).
When entering a highway on-ramp or exiting
an off-ramp, when driving on roads that are
icy, snow covered, or slippery.
When circumstances do not allow safe driving
at a constant speed.

23_VF_OM_EN_USC_t.book Page 100

STARTING AND OPERATING103
(Continued)
Active Driving Assist Indicators Are Yellow
Driver inattentiveness has been detected,
warning the driver to place hands on the
steering wheel.
Active Driving Assist Indicators Are Red
Driver inattentiveness is still being detected,
warning the driver to place hands on the
steering wheel. This warning is also issued when
the system has detected a tight curve and is
warning the driver to take control
NOTE:The driver MUST replace hands on the steering
wheel and take control of the vehicle when the
system is deactivated.

Active Driving Assist Cancelled Message

MINIMUM RISK MANEUVER
If the driver’s hands are removed from the steering
wheel, a counter will start in order to display and
activate visual and acoustic alerts. When the
absence of hands is detected, the system will start
Minimum Risk Maneuver for bringing the vehicle in
a safe position.

After 23 seconds from the absence of the hands on
the steering wheel, the Adaptive Cruise Control (ACC)
system will apply a brake jerk to warn the driver to take
vehicle control. If, after another 3 seconds the driver
does not take the control of the vehicle, the system will
apply a second brake jerk.
Subsequently, if the absence of hands on the steering
wheel persists, the system will apply an automatic
braking intervention to bring the vehicle to the stop.
As soon as the standstill condition is reached, the
hazard emergency lights will be activated. Then, the
system will unlock the doors (if previously locked). If the
driver takes control of the vehicle during the Minimum
Risk Maneuver by placing the hands on the steering
wheel or pressing the pedal throttle, the system will
behave normally and the Minimum Risk Maneuver will
be stopped.

SYSTEM STATUS

Along with changes in the system’s indicator lights
(green, yellow, and red), the system can also issue a
steering wheel vibration to accompany these warnings.
The vibration warning (if enabled) will occur if the
vehicle crosses a lane marker, for example, when
driving on a tight curve. This feature can be turned
on or off within the Uconnect system
Ú
page 134.

SYSTEM OPERATION/LIMITATIONS
WARNING!
Active Driving Assist is an SAE Level 2 Driver
Assist feature, requiring driver attention at all
times. To prevent serious injury or death:
Always remember that the Active Driver Assist
system is a convenience system that cannot
accurately detect all situations. Complete
attention is always required while driving even
when using ADA.
Always remain alert and be ready to take
control of the vehicle in the event that the
Active Driving Assist system disables.
Always keep your hands on the steering wheel
when the Active Driving Assist system is acti -
vated, deactivated, or otherwise lacks full
functionality as described in this section.

23_VF_OM_EN_USC_t.book Page 103

104STARTING AND OPERATING
The Active Driving Assist system DOES NOT:
Warn or prevent collisions with other vehicles
Steer your vehicle around stopped vehicles,
slower vehicles, construction equipment,
pedestrians, or animals
Respond to traffic lights or stop signs
Merge onto highways or exit off ramps
Turn your vehicle
Change lanes
React to cross traffic
NOTE:Adaptive Cruise Control (ACC) is a core component
of ADA. For ACC system limitations Ú page 89.
The Active Driving Assist system may have limited
or reduced functionality when one of the following
conditions occur:

The vehicle’s radar sensors and/or forward facing
camera is damaged, covered, misaligned, or
obstructed (e.g. by mud, ice, snow, etc.)

If the suspension alignment is not correct, if the
vehicle is modified (e.g. lifting or lowering the
suspension, installing different sized wheels
or tires)
Driving near highway toll booths
NOTE:If damage to the windshield occurs, have the wind -
shield replaced by an authorized dealer as soon as
possible.
PARKSENSE FRONT/REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear, and if equipped, the front fascia/bumper
and a detected obstacle when backing up or
moving forward (e.g. during a parking maneuver).
For limitations of the system (e.g. during a parking
maneuver), see Ú page 110.
NOTE:
The system is designed 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
controlling the vehicle's movements.

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 is active when the gear selector is
shifted to REVERSE or to a forward gear and an
obstacle is detected, as long as the system is on.
Do not use a hand-held device when the Active
Driving Assist system is engaged.
Maintain a safe distance from other vehicles
and pay attention to traffic conditions.
Do not place any objects on the steering wheel
(e.g. steering wheel covers) which could inter -
fere with the hand detection sensors.

Always pay attention to the road when using the
Active Driving Assist system. ADA will not steer to
avoid safety hazards, construction zones, objects,
or roadway impediments. You need to maintain
control to steer and brake the vehicle in such situ -
ations and when merging into traffic, entering the
highway, making a turn for crossing traffic, or stop-
ping for traffic control devices.

WARNING!

23_VF_OM_EN_USC_t.book Page 104

130STARTING AND OPERATING
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 buildup.
This action will also provide better engine braking.
When towing a loaded trailer up steep grades at
low speeds, holding your vehicle in FIRST gear
(using the ERS shift control) can help to avoid
transmission overheating.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 Electronic Range Select (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.
