Driving and Operating 257
When towing a trailer with ACC, it is
important to properly set the Trailer Gain.
See“Integrated Trailer Brake Control
System” inTowing Equipment 0307 for
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 0240.
Disengaging ACC
There are three ways to disengage ACC:
.Step lightly on the brake pedal.
.Press*.
.PressJ.
Erasing Speed Memory
The ACC set speed is erased from memory if
Jis pressed or if the ignition is turned off.
Weather Conditions Affecting ACC
If the interior temperature is extremely
high, the instrument cluster may indicate
that ACC is temporarily unavailable. This can
be caused by extreme hot weather
conditions with direct sunlight on the front
camera. ACC will return to normal operation
once the cabin temperature is lower. Conditions that are associated with low
visibility, such as fog, rain, snow, or road
spray, may limit ACC performance. Water
droplets from rain or snow that remain on
the windshield may also limit ACC’s ability
to detect objects.
System operation may be limited under
snow, heavy rain, or road spray conditions.
{Warning
Camera visibility may be limited and the
ACC system may not work properly if the
windshield is not clear. Do not use ACC if
moisture is present on the inside of the
windshield or the windshield washer is
used in cold weather. Turn on the front
defroster and make sure the windshield is
clear before using ACC. Before driving,
check that the windshield wipers are in
good condition and replace them if worn.
Lighting Conditions Affecting ACC
The ACC front camera can be affected by
poor lighting conditions, and ACC may have
limited performance when:
.There are changes in brightness, such as
entering and exiting tunnels, bridges, and
overpasses.
.Low sun angles cause the camera to not
detect objects, or it is more difficult to
detect objects in the same traffic lane.
.Lighting is poor in the evening or early
morning
.There are multiple changes in brightness
or shadows along the vehicle roadway.
.In a tunnel without the headlamps on,
or in a tunnel when there is a vehicle in
front that does not have its taillamps on.
.Subjected to strong light from opposing
lane traffic in the front of the vehicle,
such as high-beam headlamps from
oncoming traffic.
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 obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on the
vehicle roof.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.

258 Driving and Operating
Cleaning the Sensing System
The camera sensor on the windshield behind
the rearview mirror can become blocked by
snow, ice, dirt, mud, or debris. This area
needs to be cleaned for ACC to operate
properly.
If equipped with Super Cruise, the radar
sensors on the front of the vehicle can also
become blocked by snow, ice, dirt, mud,
or debris. These areas need to be cleaned
for ACC to operate properly.
The vehicle headlamps may need to be
cleaned due to dirt, snow, or ice. Objects
that are not illuminated correctly may be
difficult to detect.
If ACC will not operate, 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.
For cleaning instructions, see “Washing the
Vehicle” underExterior Care 0407.Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on Super Cruise-enabled roads
that are separated from opposing traffic.
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.
The Super Cruise System may initiate a lane
change maneuver in following scenarios:
.to pass slower traffic
.when the current lane is ending ahead
.to return to the initial lane
See “Super Cruise Lane Change” later in this
section and Turn and Lane-Change Signals
0 141.
{Warning
Super Cruise can only assist to maintain
lane position, or steer to change lanes,
when driving on compatible roads. You
must supervise the driving task and
monitor the road conditions. You may

need to respond to traffic events by
steering, braking, or accelerating. See
Defensive Driving.
Super Cruise is:
.Not a self-driving system
.Not a crash avoidance or warning
system
.Not a substitute for proper supervision
of the driving task.
Super Cruise uses the following to detect
the current lane position and lane markings
ahead on compatible roads under certain
conditions:
.Cameras
.Global Positioning System (GPS) sensing
.A high-precision map
.GPS-enhancement data downloaded
through OnStar
Super Cruise works with Adaptive Cruise
Control (ACC), which controls acceleration
and braking while Super Cruise is enabled
and operating. Review and understand both

using Super Cruise. SeeAdaptive Cruise
Control (Camera) 0247.
An active Connected Service plan that
includes Super Cruise Services is required to
use Super Cruise.
{Warning
Super Cruise does not perform all aspects
of driving, nor does it do everything a
driver can do. Super Cruise only steers to
maintain vehicle position in the current
lane or, under some circumstances, to
change lanes. Super Cruise can only be
used with Adaptive Cruise Control.
Super Cruise does:
.Not prevent crashes or warn of
possible crashes.
.Not steer to avoid stopped or
slow-moving vehicles, cross-traffic,
construction barriers or cones,
motorcycles, children, pedestrians,
animals, or other objects on the road.
.Not steer in response to vehicles or
objects next to your vehicle, including
vehicles attempting to enter your lane. (Continued)

.Use the turn signals.
Super Cruise Lane Change
Super Cruise can steer to perform a single
lane change under certain conditions when
requested by the driver or initiated by the
Super Cruise System.
To request a lane change:
On Demand Lane Changes 1. Verify the lane next to your vehicle is clear and conditions are safe to make a
lane change.
2. Use the turn signal lever to activate the turn signal in the direction of the desired
lane change.
3. Return the turn signal lever to the neutral position after the lane change.
See Turn and Lane-Change Signals 0141. 4. To cancel a lane change, return the turn
signal lever to the neutral position, move
the lever in the opposite direction of the
lane change, or steer manually at
any time.
Automatic Lane Changes
Super Cruise System may initiate a single
lane change when enabled through vehicle
settings under following conditions:.The Super Cruise System may initiate a
lane change to the left to pass a slower
moving vehicle ahead and a subsequent
lane change to right to return to your
original lane.
.Super Cruise System may initiate a lane
change to left or right when current lane
is ending ahead.
.To cancel a Super Cruise lane change,
return the turn signal lever to the neutral
position or move the turn signal lever.
.Super Cruise may initiate an automatic
lane change to left or right when a
slower moving vehicle is detected in the
adjacent ending lane to provide space for
merging vehicle.
If Super Cruise detects that traffic is clear,
Super Cruise will steer the vehicle to
perform the lane change. A message appears on the Driver Information Center (DIC)
during the lane change to provide more
information on the status of the lane
change.

or accelerating. SeeDefensive Driving
0 195. Super Cruise also cannot determine
whether you are awake, asleep, impaired,
or properly focused on safe driving. The
vehicle could crash into other vehicles,
drive out of the lane, or drive off the
road. Complete attention is always
required while driving, even while using
Super Cruise. Be prepared to take over
steering or apply the brakes at any time.
{Warning
To prevent serious injury or death, be
alert and pay special attention when
passing highway exits, entrances, and
crossings with Super Cruise, and be ready
to take control of the vehicle when
necessary. Changes in lane markings
around exits and entrances can
momentarily cause Super Cruise to not
detect the correct lane. If this occurs,
Super Cruise may attempt steering inputs
to bring the vehicle back into the correct
lane and, in rare circumstances, could
over-correct and cause the vehicle to
momentarily cross into a lane next to
your vehicle unless you manually steer to
maintain your lane position.
The Driver Attention System (DAS) on the
steering column continually monitors driver
head and eye position to estimate driver
attention to the road. The camera does not
record or share pictures, audio, or video. Sunglasses, hats, or other types of clothing
that change the shape of the head may
interfere with camera performance. To
improve camera performance, raise or lower
the steering wheel, or change the seat
position.
Pay close attention to the road ahead to
avoid these three increasing alerts:
