may be flashing if a vehicle ahead was
present and moved. See“Approaching
and Following a Vehicle ”later in this
section.
Once ACC has resumed, if there is no
vehicle ahead, if the vehicle ahead is
beyond the selected following gap,
or if the vehicle has exited a sharp
curve, then the vehicle speed will
increase to the set speed.
Increasing Speed While ACC is at a
Set Speed
If ACC is already activated, do one of
the following:
.Use the accelerator to get to the
higher speed. Briefly press and
release SET– and release the
accelerator pedal. The vehicle will
now cruise at the higher speed.
When the accelerator pedal is
pressed, ACC will not brake because
it is overridden. While overridden,
the ACC indicator will turn blue on
the instrument cluster and heads up
display, if equipped.
.Press and hold RES+ until the
desired set speed is displayed, then
release it.
.To increase speed in small
increments, press RES+ to the first
detent. For each press, the vehicle
goes 1 km/h (1 mph) faster.
.To increase speed in larger
increments, press RES+ to the
second detent. For each press, the
vehicle speed increases to the next
5 km/h (5 mph) mark on the
speedometer.
The set speed can also be increased
while the vehicle is stopped.
.If stopped with the brake applied,
press RES+ until the desired set
speed is displayed.
.If ACC is holding the vehicle at a
stop and there is another vehicle
directly ahead, pressing RES+ will
increase the set speed.
.Pressing RES+ when there is no
longer a vehicle ahead or the vehicle
ahead is pulling away and the brake
is not applied will cause the ACC to
resume.
When it is determined that there is no
vehicle ahead or the vehicle ahead is
beyond the selected following gap,
then the vehicle speed will increase to
the set speed. The speedometer reading can be
displayed in either English or metric
units. See
Instrument Cluster 099. The
increment value used depends on the
units displayed.
Reducing Speed While ACC is at a
Set Speed
If ACC is already activated, do one of
the following:
.Use the brake to get to the desired
lower speed. Release the brake and
press SET– . The vehicle will now
cruise at the lower speed.
.Press and hold SET– until the
desired lower speed is reached, then
release it.
.To decrease speed in smaller
increments, press SET− to the first
detent. For each press, the vehicle
goes about 1 km/h (1 mph) slower.
.To decrease speed in larger
increments, press SET− to the
second detent. For each press, the
vehicle speed decreases to the next
5 km/h (5 mph) mark on the
speedometer.
The set speed can also be decreased
while the vehicle is stopped.

Between ACC and Regular Cruise
Control”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 will pulse three
times, or three beeps will sound. See
”Alert Type ”and “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 120.
When the vehicle ahead drives away,
ACC resumes automatically if the stop
was brief. 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 0233.
To release the EPB, press the
accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0119.
{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 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 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 (Continued)

Vehicle Data Recording
and Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven or used. For example,
the vehicle uses computer modules to
monitor and control engine and
transmission performance, to monitor
the conditions for airbag deployment
and deploy them in a crash, and,
if equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store data
to help the dealer technician service
the vehicle or to help GM improve
safety or features. Some modules may
also store data about how the vehicle
is operated, such as rate of fuel
consumption or average speed. These
modules may retain personal
preferences, such as radio presets, seat
positions, and temperature settings.
Cybersecurity
GM collects information about the use
of your vehicle including operational
and safety related information. We
collect this information to provide,
evaluate, improve, and troubleshoot
our products and services and to
develop new products and services.
The protection of vehicle electronics
systems and customer data from
unauthorized outside electronic access
or control is important to GM. GM
maintains appropriate security
standards, practices, guidelines and
controls aimed at defending the
vehicle and the vehicle service
ecosystem against unauthorized
electronic access, detecting possible
malicious activity in related networks,
and responding to suspected
cybersecurity incidents in a timely,
coordinated and effective manner.
Security incidents could impact your
safety or compromise your private
data. To minimize security risks,
please do not connect your vehicle
electronic systems to unauthorized
devices or connect your vehicle to any
unknown or untrusted networks (such
as Bluetooth, WIFI or similartechnology). In the event you suspect
any security incident impacting your
data or the safe operation of your
vehicle, please stop operating your
vehicle and contact your dealer.
Event Data Recorders
This vehicle is equipped with an event
data recorder (EDR). The main
purpose of an EDR is to record, in
certain crash or near crash-like
situations, such as an air bag
deployment or hitting a road obstacle,
data that will assist in understanding
how a vehicle’s systems performed.
The EDR is designed to record data
related to vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less. The EDR
in this vehicle is designed to record
such data as:
.How various systems in your
vehicle were operating;
.Whether or not the driver and
passenger safety belts were buckled/
fastened;
.How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
