STARTING AND OPERATING89
To Vary The Speed Setting
To Increase or Decrease The Set Speed
When the Cruise Control is set, you can increase
speed by pushing the SET (+) button or decrease
the 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 until the button is released, then
the new set speed will be established.

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 until the button is released, then
the new set speed will be established.

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) up to the
maximum speed of 100 mph (160 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC
button, or normal brake pressure while slowing the
vehicle will deactivate the Cruise Control without
erasing the set speed from memory.
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 if your
vehicle is not equipped with ACC

Ú
page 88.

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 accelerate (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 280.

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.

23_VF_OM_EN_USC_t.book Page 89

94STARTING 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 tempera -
ture exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for 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 will show in the instrument cluster display.
Distance Settings

To adjust the distance setting, push the Distance
Setting Button and release. Each time the button is
pushed, the distance setting decreases by one bar
(longer). Once the longest setting is reached, if the
button is pushed again it will be set to the shortest
setting available.

If a slower moving vehicle is detected in the same lane,
the instrument cluster display will show the ACC Set
With Target Detected Light. The system will then adjust
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 Ú
page 92.
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 force.

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

23_VF_OM_EN_USC_t.book Page 94

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.

23_VF_OM_EN_USC_t.book Page 95

96STARTING AND OPERATING
NOTE:
If the “ACC Front Radar Sensor Temporarily
Blinded” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snowplow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC operation.
“ACC LIMITED FUNCTIONALITY CAMERA
BLOCKED” WARNING
The “ACC Limited Functionality Camera Blocked”
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 and fog. The ACC
system may also become temporarily blinded due
to obstructions, such as mud, dirt, or ice on
windshield and fog on the inside of glass. In these
cases, the instrument cluster display will read
“ACC Limited Functionality Camera Blocked” and
the system will have degraded performance. This message can sometimes be displayed while
driving in adverse weather conditions. The ACC
system will recover after the vehicle has left these
areas. Under rare conditions, when the camera is
not tracking any vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rearview
mirror. They may require cleaning or removal of an
obstruction.

When the condition that created limited functionality
is no longer present, the system will return to full
functionality.

NOTE:If the “ACC Limited Functionality Camera Blocked”
message occurs frequently (e.g. more than once
on every trip) without any snow, rain, mud, or other
obstruction, have the windshield and forward
facing camera inspected at an authorized dealer.
SERVICE ACC WARNING

If the system turns off, and the instrument cluster
display reads “ACC Unavailable Service Required” or
“Cruise Unavailable Service Required”, there may be an
internal system fault or a temporary malfunction that
limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be
temporarily unavailable. If this occurs, try activating
ACC again later, following an ignition cycle. If the
problem persists, see an authorized dealer.

Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
TOWING A TRAILER
Towing a trailer is not recommended when
using ACC.

23_VF_OM_EN_USC_t.book Page 96

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

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.
