path, ACC works like regular cruise control.
ACC uses a windshield mounted front
camera sensor.
If equipped with Super Cruise, ACC uses a
radar sensor(s) as well to detect other
vehicles. SeeRadio Frequency Statement
0 450.
If a vehicle is detected in your path, ACC can
apply acceleration or limited, moderate
braking to maintain the selected following
gap. To disengage ACC, apply the brake.
If ACC is controlling the vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC)
system activates, ACC may automatically
disengage. See Traction Control/Electronic
Stability Control 0247. When road
conditions allow ACC to be safely used, ACC
can be turned back on. Disabling the TCS or
StabiliTrak/ESC system will disengage and
prevent engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate, especially
when used on expressways, freeways, and
interstate highways. When used on other
roads, you may need to take over the
control of braking or acceleration more
often.{Warning
ACC has limited braking ability and may
not have time to slow the vehicle down
enough to avoid a collision with another
vehicle you are following. This can occur
when vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver” later in this section.
Complete attention is always required
while driving and you should be ready to
take action and apply the brakes. See
Defensive Driving 0206.
{Warning
ACC will not detect or brake for children,
pedestrians, animals, or other objects.
Do not use ACC when:
.On winding and hilly roads or when
the camera sensor is blocked by snow,
ice, or dirt. The system may not
detect a vehicle ahead. Keep the
windshield and headlamps clean.
.When visibility is poor due to rain,
snow, fog, dirt, insect residue, or dust;
when other foreign objects obscure

Warning (Continued)
the camera’s view; or when the
vehicle in front or oncoming traffic
causes additional environmental
obstructions, such as road spray. ACC
performance is limited under these
conditions.
.On slippery roads where fast changes
in tire traction can cause excessive
wheel slip
.With extremely heavy cargo loaded in
the cargo area or rear seat
.When towing a trailer

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 in front of your vehicle that have
a rear aspect that is low, small,
or irregular
.An empty truck or trailer that has no
cargo in the cargo bed
.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
.Vehicles that are low to the road surface
.Objects that are close to the front of your
vehicle
.Vehicles on which extremely heavy cargo
is loaded in the cargo area or rear seat
ACC Automatically Disengages
ACC may automatically disengage and the
driver will need to manually apply the
brakes to slow the vehicle if:
.The front camera is blocked or visibility is
reduced.
.The Traction Control System (TCS) or
StabiliTrak/ESC system has activated or
been disabled.
.There is a fault in the system.
.A DIC message displays to indicate that
ACC is temporarily unavailable.
.The front radar is blocked and the vehicle
is equipped with Super Cruise.
.The radar falsely reports blockage when
driving in a desert or remote area with
no other vehicles or roadside objects, and
the vehicle is equipped with Super Cruise. The ACC indicator will turn white when ACC
is no longer active.
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 system.
Notification to Resume ACC
ACC will maintain a follow gap behind a
detected vehicle and slow 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 (if equipped) will pulse
three times, or three beeps will sound. See
”Alert Type” and“Adaptive Cruise Go
Notifier” in“Collision/Detection Systems”
under Vehicle Personalization 0137.
If equipped with Driver Attention System
(DAS) located on top of the steering column,
when the vehicle ahead drives away, and
DAS determines if the driver's attention is
on the road ahead, ACC resumes
automatically. See “Attention to the Road”

P (Park) and turn off the ignition before
leaving the vehicle.
ACC Override
If using the accelerator pedal while ACC is
active, the ACC indicator turns blue on the
instrument cluster and in the HUD,
if equipped, to indicate that automatic
braking will not occur. ACC will resume
operation when the accelerator pedal is not
being pressed.
{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 (Continued)

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 in a sharp
curve. It may reduce the vehicle speed if the
curve is too sharp.

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 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 0414.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. when a lane
change is initiated by the driver using the
turn signal lever.
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

Control (Camera) 0256.
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

Attention to the Road
{Warning
Super Cruise is a driver assistance system
and cannot accurately detect or predict
all situations. Super Cruise is not a crash
avoidance system. To prevent serious
injury or death, you must supervise the
driving task and monitor the road
conditions. You may need to respond to
traffic events by steering, braking,
or accelerating. SeeDefensive Driving
0 206. 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:
