if there is no vehicle ahead,
if the vehicle ahead is beyond
the selected following gap,
or if the vehicle has exited a

to the higher speed. Briefly
press and release SET– and
release the accelerator

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 0119. The
increment value used depends

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

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

connect your vehicle to any
unknown or untrusted
networks (such as Bluetooth,
WIFI or similar technology). 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,
.How fast the vehicle was
traveling.
These data can help provide a
better understanding of the
circumstances in which
crashes and injuries occur.
Note
EDR data are recorded by
your vehicle only if a non-trivial
crash situation occurs; no data
are recorded by the EDR
under normal driving
conditions and no personal
data (e.g., name, gender, age,
and crash location) are
recorded. However, other
parties, such as law
enforcement, could combine
the EDR data with the type of personally identifying data
routinely acquired during a
crash investigation.
To read data recorded by an
EDR, special equipment is
required, and access to the
vehicle or the EDR is needed.
In addition to the vehicle
manufacturer, other parties,
such as law enforcement, that
have the special equipment,
can read the information if
they have access to the
vehicle or the EDR.
GM will not access these data
or share it with others except:
with the consent of the vehicle
owner or, if the vehicle is
leased, with the consent of the
lessee; in response to an
official request by police or
similar government office; as
part of GM's defense of
litigation through the
discovery process; or, as
permitted by law. Data that
GM collects or receives may
also be used for GM research
needs or may be made
