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

226 Driving and Operating
curve is too sharp, ACC may temporarily
reduce the vehicle speed while navigating
the curve.
The curve speed control indicator light
b
may illuminate green when ACC is actively
controlling the vehicle speed and detects a
sharp curve in the road ahead.
ACC may automatically increase the vehicle
speed when exiting out of the curve,
however ACC will not exceed the set speed.
When following a vehicle and entering a
curve, ACC may not detect the vehicle ahead
and accelerate to the set speed. When this
happens, the vehicle ahead indicator will not
appear.
ACC may detect a vehicle that is not in your
lane and apply the brakes.
ACC may occasionally provide an alert and/
or braking that is considered unnecessary.
It could respond to vehicles in different
lanes or stationary objects when entering or
exiting a curve. This is normal operation.
The vehicle does not need service.
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead until it
is completely in the lane. You may need to
manually apply the brakes.
Objects Not Directly in Front of Your Vehicle
The ACC system may not be able to detect
all objects in front of the vehicle if:
.The vehicle or object ahead is not within
your lane.
.The vehicle ahead is shifted, not centered,
or is shifted to one side of the lane.
Driving in Narrow Lanes
Vehicles in adjacent traffic lanes or roadside
objects may be incorrectly detected when
located along the roadway.
Do Not Use ACC on Hills
Do not use ACC when driving on steep hills.
ACC will not detect a vehicle ahead.

Towing with ACC
If equipped when towing a trailer, ACC
driving characteristics such as following gap,
acceleration rates, and braking rates may be
modified to provide a better towing
experience.
When ACC is used with vehicles equipped
with an aftermarket trailer brake controller,
disengage ACC before applying the manual
trailer brake. ACC will not automatically
disengage when the manual trailer brake is
applied.
ACC may be used when towing a trailer if
the trailer is within the GM-approved
allowable size and weight limits. SeeTrailer
Towing 0297.
When towing a trailer with ACC, it is
important to properly set the Trailer Gain.
See “Integrated Trailer Brake Control
System” inTowing Equipment 0301 for
information about the Trailer Gain
adjustment procedure.
Use Tow/Haul mode when driving down
steep hills or mountain grades, or when
hauling heavy loads. See Driver Mode
Control 0209. Disengaging ACC
There are four ways to disengage ACC:
.Press*.
.Lightly apply the brake pedal.
.Apply the Regen on Demand steering
wheel paddle, if equipped.
.Press5.
Erasing Speed Memory
The ACC set speed is erased from memory if
5is pressed or if the vehicle is turned off.
Weather Conditions Affecting ACC
ACC system operation may be limited under
snow, heavy rain, or road spray conditions.
Accessory Installations and Vehicle
Modifications
.Do not install or place any object around
the front camera windshield area that
would obstruct the front camera view.
.Do not install objects on top of the
vehicle that overhang and may obstruct
the front camera, such as a canoe, kayak,
or other items that can be transported on
top of the vehicle.
.Do not modify the hood, headlamps,
or fog lamps, as this may limit the
camera’s ability to detect an object. Cleaning the Sensing System
The camera sensor on the windshield behind
the rearview mirror, and the sensors on the
front of the vehicle can become blocked by
snow, ice, dirt, mud, or other debris. These
areas must be clean for ACC to operate
properly. For proper cleaning instructions,
see the section
“Washing the Vehicle” in
Exterior Care 0379.
If driving conditions temporarily prevent
normal and safe ACC operation, regular
cruise control may be available. See
“Switching Between ACC and Regular Cruise
Control” previously in this section. Always
consider driving conditions before using
either cruise control system.
Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on Super Cruise-enabled roads.
Super Cruise can also steer to perform a
lane change under certain conditions on
Super Cruise-enabled roads.
A lane change can be initiated by the driver
using the turn signal lever.
