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

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.

.Performance for Transparent Trailer and
Jack Knife Detection are optimized when
the entered value for trailer width reflects
the width of the box of the trailer. If total
width is entered:
.The inlayed camera view in
Transparent Trailer View may appear
wider than the trailer face.
.Jack Knife Detection alerts may
activate prematurely.
.Performance for Rear Trailer Guidance
Lines and Trailer Length Indicator Overlays
are optimized when the entered value for
trailer width reflects the total width of
the trailer including outboard wheels.
If the trailer box width is entered:
.The Rear Trailer Guidance Lines will
appear narrower than the actual path
of the trailer.
.The Trailer Length Indicator Overlays
will appear closer and possibly overlap
with the trailer.
Park Assist
With Front and Rear Park Assist, as the
vehicle moves at speeds of less than 8 km/h
(5 mph) the sensors on the bumpers may
detect objects up to 1.2 m (4 ft) in front and
1.8 m (6 ft) behind the vehicle within a zone
25 cm (10 in) high off the ground and below
bumper level. These detection distances may
be shorter during warmer or humid weather.
Blocked sensors will not detect objects and
can also cause false detections. Keep the
sensors clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car wash in
freezing temperatures.
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects located below the bumper or
that are too close or too far from the
vehicle. It is not available at speeds
greater than 8 km/h (5 mph). To prevent
injury, death, or vehicle damage, even
with Park Assist, always check the area
around the vehicle and check all mirrors
before moving forward or backing.
The instrument cluster may have a Park
Assist display with bars that show“distance
to object” and object location information
for the Front and Rear Park Assist system.
As the object gets closer, more bars light up
and the bars change color from yellow to
amber to red.
When an object is first detected in the rear,
one beep will be heard from the rear,
or both sides of the Safety Alert Seat will
pulse two times. When an object is very
close —<0.4 m (1.5 ft) in the vehicle rear or
<0.3 m (1 ft) in the vehicle front —a
continuous beep will sound from the rear or
front depending on object location, or both
sides of the Safety Alert Seat will pulse five
times. Beeps for FPA are higher pitched than
for RPA.
