Cruise Control
Adaptive Cruise
Control (Advanced)
Adaptive Cruise Control (ACC)
allows the cruise control set
speed and following gap to be
selected. Read this entire
section before using this
system. The following gap is
the following time (or distance)
between your vehicle and a
vehicle detected directly
ahead in your path, moving in
the same direction. If no
vehicle is detected in your
path, ACC works like regular
cruise control. ACC uses a
camera and radar sensor(s) to
detect other vehicles. See
Radio Frequency Statement
0395.
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
0221. 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 0196.
{Warning
ACC will not detect or brake
for children, pedestrians,
animals, or other objects.

Joff when cruise is not
being used.
Select the set speed desired
for ACC. This is the vehicle
speed when no vehicle is
detected in your path.
While the vehicle is moving,
ACC will not set at a speed
below a minimum speed,
although it can be resumed.
If equipped with Super Cruise,
this minimum speed is 5 km/h
(3 mph), otherwise, it is
25 km/h (15 mph). The minimum
allowable set speed is 25 km/h
(15 mph).

Driving and Operating 231
Following distance gap will
return to the original selection
after hold.
Alerting the Driver
If ACC is engaged, driver
action may be required when
ACC cannot apply sufficient
braking because of
approaching a vehicle too
rapidly.
When this condition occurs,
the 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. Touch the Settings
icon on the infotainment home
page. Select“Vehicle”to
display the list of available
options and select “Collision/
Detection Systems”. See Defensive Driving
0196.
Approaching and Following a
Vehicle
The vehicle ahead indicator is
in the instrument cluster.
It only displays when a vehicle
is detected in your vehicle’s
path moving in the same
direction. If this symbol is not
displaying, ACC will not
respond to or brake for
vehicles ahead.
ACC automatically slows the
vehicle down and adjusts
vehicle speed to follow a
detected vehicle ahead at the
selected following gap. The
vehicle speed increases or
decreases to follow a
detected vehicle in front of
your vehicle when that vehicle
is traveling slower than your vehicle set speed. It may apply
limited braking, if necessary.
When braking is active, the
brake lamps will come 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.
{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

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 (Continued)

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
been disabled.
.There is a fault in the
system.
.The radar falsely reports
blockage when driving in a
desert or remote area with
no other vehicles or
roadside objects.
.A DIC message may display
to indicate that ACC is
temporarily unavailable.
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

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
will pulse three times, or three
beeps will sound. Touch the
Settings icon on the
infotainment home page.
Select“Vehicle” to display the
list of available options and
select ”Alert Type” and
“Adaptive Cruise Go Notifier”
in “Collision/Detection

driver's attention is on the
road ahead, ACC resumes automatically. See "Attention
to the Road" under Super
Cruise
0236. If necessary,
press RES+ or 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 automatically applies the
Electric Parking Brake (EPB)
to hold the vehicle. The EPB
status light will turn on. See
Electric Parking Brake 0217.
A DIC warning message may
display indicating to shift to
P (Park) before exiting the
vehicle. See Vehicle Messages
0 134.
{Warning

{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
in a sharp curve. It may briefly
reduce the vehicle speed if the
curve is too sharp.
The curve speed control
indicator
bmay illuminate
green when ACC is actively
controlling the vehicle speed
and detects a sharp curve on
the road ahead. ACC automatically slows the
vehicle down while navigating
the curve and may increase
speed out of the curve, but 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. The brakes may need
to be manually applied.
Objects Not Directly in Front
