Medium Gap Setting
Near Gap SettingIf equipped, and a trailer is electrically
connected, the gap setting display will be as
follows:
Far Gap Setting with Trailer
Medium Gap Setting with Trailer
Near Gap Setting with Trailer
Since each gap setting corresponds to a
following time (Far, Medium, or Near), the
following distance will vary based on vehicle
speed. The faster the vehicle speed, the
longer the following distance will be
between your vehicle and the vehicle
detected ahead. Consider traffic and weather
conditions when selecting the following gap.
The range of selectable gaps may not be
appropriate for all drivers and driving
conditions.
Changing the gap setting automatically
changes the alert timing sensitivity (Far,
Medium, or Near) for the Forward Collision
Alert (FCA) feature. See Forward Collision
Alert (FCA) System 0261.

temporarily increase the gap distance.
When you release
[, ACC may
accelerate to resume the ACC set speed
while maintaining the normal gap
distance setting.
.When your vehicle is stopped, press and
hold
[to prevent ACC from
automatically resuming the set speed,
which can allow for merging traffic to

or the apply the accelerator pedal. Alerting the Driver
If ACC is engaged, driver action may be
required when ACC cannot apply sufficient
braking because your vehicle is approaching
a vehicle ahead too quickly.
When this condition occurs, the red collision
alert symbol will flash on the windshield.
Either eight beeps will sound from the front,
or both sides of the Safety Alert Seat will
pulse five times. To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
See
Defensive Driving 0183.
Approaching and Following a Vehicle
The vehicle ahead indicator light is displayed
in the instrument cluster and the HUD,
if equipped. It only displays when a vehicle
is detected in your vehicle’s path and is
moving in the same direction. If the vehicle
ahead indicator light does not appear in the
instrument cluster, then ACC will not
respond to, or brake for, vehicles ahead.
While ACC is active, ACC will automatically
adjust your vehicle’s speed to follow a
detected vehicle ahead according to the
selected following gap setting. ACC may
decrease your vehicle’s cruise speed when
following a detected vehicle ahead that is
traveling slower than your ACC set speed.
ACC may apply limited braking, if necessary.
When ACC automatic braking is active, the
brake lamps will turn on. The automatic
braking may feel or sound different than if
the brakes were applied manually. This is
normal.
Passing a Vehicle While Using ACC
If the set speed is high enough, and the left
turn signal is used to pass a vehicle ahead
in the selected following gap, ACC may
assist by gradually accelerating the vehicle
prior to the lane change.

224 Driving and Operating
{Warning
When using ACC to pass a vehicle or
perform a lane change, the following
distance to the vehicle being passed may
be reduced. ACC may not apply sufficient
acceleration or braking when passing a
vehicle or performing a lane change.
Always be ready to manually accelerate
or brake to complete the pass or lane
change.
Stationary or Very Slow-Moving Objects
{Warning
ACC may not detect and react to stopped
or slow-moving vehicles ahead of you. For
example, the system may not brake for a
vehicle it has never detected moving. This
can occur in stop-and-go traffic or when a
vehicle suddenly appears due to a vehicle
ahead changing lanes. Your vehicle may
not stop and could cause a crash. Use
caution when using ACC. Your complete
attention is always required while driving
and you should be ready to take action
and apply the brakes. Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.Vehicles with cargo extending from the
back end.
.Non-standard shaped vehicles, such as
vehicle transport, vehicles with a side car
fitted, or horse carriages.
.Objects that are close to the front of your
vehicle.
ACC Automatically Disengages
ACC may automatically disengage and the
driver will need to manually apply the
brakes to slow the vehicle if:
.The sensors are blocked.
.The Traction Control System (TCS) or
StabiliTrak/ESC system has activated or
has been disabled.
.If equipped with Air Suspension, the
vehicle ride height is outside normal
operating range. See Air Suspension0211.
.There is a fault in the system.
.The radar falsely reports a blockage when
driving in a remote area with no other
vehicles or roadside objects.
A DIC message may display to indicate that
ACC is temporarily unavailable. The ACC indicator light will turn white when
ACC is disengaged.
In some cases, when ACC is temporarily
unavailable, regular cruise control may be
used. See
“Switching Between ACC and
Regular Cruise Control” previously in this
section. Always consider driving conditions
before using either cruise control mode.
Notification to Resume ACC
ACC will maintain a follow distance gap
behind a detected vehicle, and will slow
down your vehicle to a stop behind that
vehicle.
If the stopped vehicle ahead has driven
away and ACC has not resumed, the vehicle
ahead indicator will flash as a reminder to
check traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three times,
or three beeps will sound. To view available
settings from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems > Alert Type > Adaptive Cruise Go
Notifier.
If equipped with Driver Attention System
(DAS) located on top of the steering column,
when the vehicle ahead drives away, and
the DAS determines that the driver's

attention is on the road ahead, ACC
automatically resumes. For more
information, see“Attention to the Road" in
Super Cruise 0227. If necessary, briefly press
and release the thumbwheel up to +RES or
apply the accelerator pedal to resume ACC.
If stopped for more than two minutes, or if
the driver door is opened and the driver
seat belt is unbuckled, the ACC system
automatically applies the Electric Parking
Brake (EPB) to hold the vehicle. The EPB
light will turn on. To release the EPB, press
the accelerator pedal. See Electric Parking
Brake 0205.
A DIC warning message may display
indicating to shift to P (Park) before exiting
the vehicle.
{Warning
If ACC has stopped the vehicle, and if ACC
is disengaged, turned off, or canceled, the
vehicle will no longer be held at a stop.
The vehicle can move. When ACC is
holding the vehicle at a stop, always be
prepared to manually apply the brakes.
{Warning
Leaving the vehicle without placing it in
P (Park) can be dangerous. Do not leave
the vehicle while it is being held at a
stop by ACC. Always place the vehicle in
P (Park) and turn it off before leaving the
vehicle.
ACC Override
If you apply the accelerator pedal while ACC
is engaged, the ACC indicator light turns
blue in the instrument cluster and the HUD,
if equipped, indicating that ACC braking will
not occur. ACC will resume operation when
the accelerator pedal is released.
{Warning
The ACC will not automatically apply the
brakes if your foot is resting on the
accelerator pedal. You could crash into a
vehicle ahead of you. Curves in the Road
{Warning
On curves, ACC may not detect a vehicle
ahead in your lane. You could be startled
if the vehicle accelerates up to the set
speed, especially when following a vehicle
exiting or entering exit ramps. You could
lose control of the vehicle or crash. Do
not use ACC while driving on an entrance
or exit ramp. Always be ready to use the
brakes if necessary.
{Warning
On curves, ACC may respond to a vehicle
in another lane, or may not have time to
react to a vehicle in your lane. You could
crash into a vehicle ahead of you, or lose
control of your vehicle. Give extra
attention in curves and be ready to use
the brakes if necessary. Select an
appropriate speed while driving in curves.
ACC may operate differently when the
vehicle approaches a sharp curve in the road
ahead. If the ACC system detects that a

Zwill be blue. The driver is in control
of steering and Super Cruise is not steering
the vehicle.
When the vehicle is positioned in the center
of the lane, the steering wheel light bar and
Zdisplay will turn green, indicating Super
Cruise is steering the vehicle.
When Super Cruise controls the steering,
traffic and other conditions and laws permit,
and it is safe to do so, your hands can be
taken off the steering wheel.
Always pay attention to the road and the
operation of the vehicle. Always monitor
and be attentive of surrounding traffic,
including vehicles that may cross the road in
front of your vehicle.
Super Cruise steering can be overridden with
manual steering at any time. When Super
Cruise is engaged, always be prepared to
take immediate action —including steering,
accelerating, and braking quickly,
if necessary.
When Super Cruise is engaged, the Forward
Collision system will alert and brake. See
Forward Collision Alert (FCA) System 0261. Steering Manually and Changing Lanes
The vehicle can always be manually steered,
even with Super Cruise engaged; for
example, when manually changing lanes.
When the steering wheel is moved
manually, the steering wheel light bar
flashes blue andZon the instrument
cluster turns blue to indicate Super Cruise is
not steering the vehicle.
When ready to allow Super Cruise to
resume steering again, position the vehicle
in the center of the lane, hold the steering
wheel until the steering wheel light bar
turns green, and then release the steering
wheel when it is safe to do so.
