Refer to the aftermarket
electric trailer brake controller
owner's manual to determine
wire color coding of the
electric trailer brake controller.
The wire colors on the brake
controller may be different
from the vehicle. The electric
trailer brake controller should
be installed by your dealer or a
qualified service center.
If equipped, there are four
blunt cut wires inside the front
driver side instrument panel.
It will be necessary to have a technician connect the 12-volt
power to the engine
compartment fuse block.
Trailer Lamps
Always check that all trailer
lamps are working at the
beginning of each trip, and
periodically on longer trips.
Turn Signals When
Towing a Trailer
When properly connected, the
trailer turn signals will
illuminate to indicate the
vehicle is turning, changing
lanes, or stopping. When
towing a trailer, the arrows on
the instrument cluster will
illuminate even if the trailer is
not properly connected or the
bulbs are burned out.
Trailer Sway
Control (TSC)
Vehicles with StabiliTrak/
Electronic Stability Control
(ESC) have a Trailer Sway
Control (TSC) feature. Trailersway is unintended
side-to-side motion of a trailer
while towing. If the vehicle is
towing a trailer and the TSC
detects that sway is
increasing, the vehicle brakes
are selectively applied at each
wheel, to help reduce
excessive trailer sway.
If equipped with the
Integrated Trailer Brake
Control (ITBC) system, and the
trailer has an electric brake
system, StabiliTrak/ESC may
also apply the trailer brakes.
If TSC is enabled, the Traction
Control System (TCS)/
StabiliTrak/ESC warning light
will flash on the instrument
cluster. Reduce vehicle speed
by gradually removing your
foot from the accelerator.
If trailer sway continues,

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 orconnect 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
