94STARTING AND OPERATING
Adaptive Cruise Control Off
When ACC is deactivated, all ACC visualizations will not be
shown in the instrument cluster display.
Adaptive Cruise Control Ready
When ACC is activated, but the vehicle speed setting has
not been selected, the white ACC icon will illuminate above
dashes in place of a speed in the instrument cluster
display.
Adaptive Cruise Control Set
When the vehicle has reached the desired speed, push
the SET switch up or down briefly, then release. When the
ACC speed is set, the green ACC icon over the set speed
will illuminate in the instrument cluster display.
When the ACC menu screen is not being viewed in the
instrument cluster display, a green triangle will illuminate
on the speedometer at the location of the set speed.
NOTE:If the ACC system is canceled or paused, the triangle on
the speedometer will change to white, indicating the
saved set speed for when the RES button pushed.
Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is 19 mph
(30 km/h).
NOTE:You cannot engage ACC under the following conditions:
When the brakes are applied
 When the parking brake is applied
 When the gear selector 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
To Activate/Deactivate
Push and release the Mode button located on the left side
of the steering wheel to activate ACC. Then proceed to
setting the desired speed as described in the next section.
NOTE:Active Speed Limiter will be unavailable while ACC is in
use.
To turn the system off, push and release the Mode button
again. At this time, the system will turn off and Active
Speed Limiter will be active.
The system will also turn off during any of the conditions
listed in “To Turn Off”
Úpage 95.
To Set A Desired Speed
When the vehicle has reached the desired speed, push
the SET switch up or down briefly, then release. The
instrument cluster display will show the set speed.

If ACC is set when the vehicle speed is
below
19 mph
(30 km/h), the set speed will default to 19 mph (30 km/h).

If either system is set when the vehicle speed is above
19 mph (30 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 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 accelerator pedal.
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!
If the Active Speed Limiter is active, 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.

STARTING AND OPERATING95
To Cancel
The following conditions cancel ACC:
The brake pedal is applied
 The CANC (cancel) button is pushed
 The Anti-Lock Brake System (ABS) activates
 The gear selector is removed from the DRIVE position
 The Electronic Stability Control/Traction Control
System (ESC/TCS) activates
 The vehicle parking brake is applied
 The Trailer Sway Control (TSC) activates
 The driver switches ESC to Full Off mode
 The braking temperature exceeds normal range
(overheated)
 Driver seat belt is unbuckled at low speeds
 Driver door is opened at low speeds
To Turn Off
The system will turn off and clear the set speed in memory
if:
The Mode button is pushed
 The ignition is placed in the OFF position
To Resume
If ACC was canceled, and there is a set speed in memory,
push the RES (resume) button and remove your foot from
the accelerator pedal. The instrument cluster display will
show the last set speed. Resume can be used at any speed above 0 mph (0 km/h)
when ACC is active.
NOTE: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 adjust the speed by pushing
the SET switch upward or decrease the speed by pushing
the SET switch downward.
U.S. Speed (mph)

Pushing the SET switch upward or downward to the first
detent will result in a 1 mph speed adjustment. Each
subsequent movement of the switch to the first detent
will result in an adjustment of 1 mph.
 If the switch is pushed upward or downward briefly to
the second detent, the set speed will adjust in 5 mph
increments. The new set speed is reflected in the
instrument cluster display. 
If the switch is held upward or downward, the set speed
will continue to adjust until the switch is released.
Metric Speed (km/h)
 Pushing the SET switch upward or downward to the first
detent will result in a 1 km/h speed adjustment. Each
subsequent movement of the switch to the first detent
will result in an adjustment of 1 km/h.

 If the switch is pushed upward or downward briefly to
the second detent, the set speed will adjust in 10 km/h
increments. The new set speed is reflected in the instru -
ment cluster display.

 If the switch is held upward or downward, the set speed
will continue to adjust until the switch is released.
NOTE:
When you override the set speed by pushing the SET
switch upward or downward, the new set speed will be
the current speed of the vehicle.
 When you use the SET switch to decelerate, if the
engine’s braking power does not slow the vehicle suffi -
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
 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).
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.

96STARTING AND OPERATING
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.
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 decrease the distance setting, push the Distance
Setting Button and release. Each time the button is
pushed, the distance setting increases 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 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
Úpage 94.
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!” (or
similar warning message) 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 neces -
sarily 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.
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.
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

STARTING AND OPERATING97
Display Warnings And Maintenance
LIMITED OPERATION WARNING
If a warning message appears in the instrument cluster
display indicating limited operation of the ACC system, a
fault or obstruction of the system’s radar or camera may
have occurred.
If an obstruction is detected, clean the area of the
windshield opposite the interior rearview mirror, where the
camera is located, as well as the area of the front fascia/
bumper where the sensor is located. Then check that the
message has disappeared.
When the conditions limiting the system function as been
corrected, normal operation will resume.
Should the fault persist, contact 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.
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

23_GG_OM_EN_USC_t.book Page 97

98STARTING AND OPERATING
LANE CHANGING
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the following lane
changing example, 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

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

23_GG_OM_EN_USC_t.book Page 98

STARTING AND OPERATING101
Setting The ACC Speed Using Confirmation Mode
When Confirmation Mode is selected, and the Traffic Sign
Recognition (TSR) system detects a new speed limit sign,
the driver will confirm this new speed by pushing
the SET switch upward briefly, then releasing. This
confirmation of the new speed must be done within
five seconds of a newly detected speed limit sign being
shown in the instrument cluster display.
Setting The ACC Speed Using Automatic Mode
When Automatic Mode is selected, the ACC system will
automatically adjust the speed setting when the TSR
system detects a new speed limit sign.
The driver can reject this new speed by pushing the SET
switch upward briefly, then releasing within five seconds
of the new speed limit sign being detected and the speed
being adjusted.
Set the desired following distance as you normally would
using the ACC system
Úpage 96.
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 92.
NOTE:

The driver should always obey traffic laws and speed
limits. Never drive above applicable speed limit restric -
tions.
 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 measure
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 an adjacent 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.
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 turn off the Active Driving Assist system:
 When driving in complex driving situations
(e.g. urban environments, construction zones, etc.),
adverse weather or low visibility conditions (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 off-ramp, when driving on
roads that are icy, snow covered, or slippery.
 When driving during difficult or uncertain conditions.

STARTING AND OPERATING103
System Deactivation
The system will be deactivated in any of the following
situations:
If the system has detected driver inattentiveness, and
has gone through all escalation warnings after hands
are no longer detected on the steering wheel
 If the vehicle is driving in constant traffic
 If lane markings are no longer detected
 If the brake pedal is pressed or ACC system is deacti -
vated
 If the Active Driving Assist on/off button is pushed
again (ADA will turn off)
 If a turn signal is used (unless a target is in the blind
spot zone on the same side the turn signal is being
applied)
 If the driver applies enough input to the steering wheel
 If the driver’s seat belt is released
 If the vehicle speed exceeds 93 mph (150 km/h)
 If the Active Driving Assist on/off button is pushed
again (ADA will turn off)
 If the Forward Collision Warning (FCW) system
becomes active and is providing warnings/braking
 If there is glare from the sun on the vehicle’s camera
 If the vehicle is driving on tight curves 
If the camera has decreased visibility due to rain,
snow, etc.
 If the driver quickly applies the accelerator pedal
NOTE:
Pushing the Active Driving Assist on/off button or deac -
tivating ACC will turn the system off. All other deactiva -
tion conditions will place the system back into the
“enabled” state with the steering wheel indicator
displayed in white until all engagement conditions are
met again.
 When the system is deactivated, the system status
indicator lights will turn off, the LaneSense system will
return to its previous state, and ACC will disable.
INDICATIONS ON THE DISPLAY
The Active Driving Assist system status can always be
viewed in the instrument cluster display, and status
changes are shown by changes in color of the system’s
indicator lights.
As the system detects driver inattentiveness as previously
described
Úpage 101, the system status indicator lights
will change from green, to yellow, to red. The following
indicators will change in color as warnings to the driver
escalate:
 Active Driving Assist Indicator (steering wheel icon in
the instrument cluster display)
 Glow effect of the instrument cluster display
If driver attention is not returned, the system will
deactivate. Active Driving Assist Indicators Are Off

ADA is not turned on/enabled by the driver.
Active Driving Assist Indicators Are White
 ADA is turned on/enabled by the driver, but the system
is not actively steering and providing speed control for
the vehicle.
Active Driving Assist Indicators Are Green
 The system detects driver is attentive and is actively
steering and providing speed control for the vehicle.
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, or driver
take-over is being requested, 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.

23_GG_OM_EN_USC_t.book Page 103

104STARTING AND OPERATING
MINIMUM RISK MANEUVER
When the vehicle begins the hands-off steering wheel
warning escalation, previously described, the system will
initiate the Minimum Risk Maneuver for bringing the
vehicle to a stop.
After 23 seconds from the initial 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.
If the absence of hands on the steering wheel persists, the
system will apply automatic braking to bring the vehicle to
the stop and activate the vehicle’s hazard warning lights.
After the vehicle is stopped, the system will unlock the
doors (if previously locked).
NOTE:If the driver takes control of the vehicle during the
Minimum Risk Maneuver by placing hands on the steering
wheel or pressing the accelerator, the system Minimum
Risk Maneuver will be canceled, and the ADA system will
resume normal function.
SYSTEM STATUS
Along with changes in the system’s indicator lights (green,
yellow, and red), the system can also issue several
accompanying warnings intended to provide the driver
with enough time to react, avoid or mitigate a potential
collision.
Two haptic brake jerk warnings will be issued (red
warning light is being issued).
 A steering wheel vibration warning (if enabled) will
occur if the vehicle crosses a lane marker, for example,
when driving on a tight curve. The steering wheel vibra -
tion feature can be turned on or off within the Uconnect
system
Úpage 130.
SYSTEM OPERATION/LIMITATIONS
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, see Úpage 92.
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 windshield
replaced by an authorized dealer as soon as possible.
WARNING!
The DDD system is an aid for driving and does not
relieve the driver of the responsibility of driving the
vehicle. If you experience fatigue while driving, pull over
safely for a break without waiting for the DDD warnings.
Only return to the road when you are in the right
physical and mental condition to prevent endangering
yourself and other drivers.
