4. Good Battery Positive (+)Terminal
The discharged battery positive (+)
terminal and the discharged battery
negative (–) grounding point are on
the driver side of the vehicle.
The good battery negative (–) terminal
and the good battery positive (+)
terminal are on the battery of the
vehicle providing the jump start.
The discharged battery positive (+)
terminal is under a cover. Remove the
cover to expose the terminal.
1. Check the other vehicle. It must have a 12-volt battery with a
negative ground system.
Caution
If the other vehicle does not have a
12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Position the two vehicles so that they are not touching. 3. Set the parking brake firmly and
put the transmission in P (Park).
See Shifting Into Park 0236.
Caution
If any accessories are left on or
plugged in during the jump starting
procedure, they could be damaged.
The repairs would not be covered
by the vehicle warranty. Whenever
possible, turn off or unplug all
accessories on either vehicle when
jump starting.
4. Turn the ignition off. Turn off all lights and accessories in both
vehicles, except the hazard warning
flashers if needed.
{Warning
An electric fan can start up even
when the engine is not running and
can injure you. Keep hands,
clothing, and tools away from any
underhood electric fan.
{Warning
Using a match near a battery can
cause battery gas to explode. People
have been hurt doing this, and
some have been blinded. Use a
flashlight if you need more light.
Battery fluid contains acid that can
burn you. Do not get it on you.
If you accidentally get it in your
eyes or on your skin, flush the place
with water and get medical help
immediately.
{Warning
Fans or other moving engine parts
can injure you badly. Keep your
hands away from moving parts
once the engine is running.

Caution (Continued)
must be in N (Neutral) with the
electric parking brake released
when using the tow eye.
Contact a professional towing service
if the disabled vehicle must be
transported. GM recommends a
flatbed tow truck to transport a
disabled vehicle. Use ramps to help
reduce approach angles, if necessary.
If equipped, a tow eye may be located
near the spare tire or emergency jack.
Do not use the tow eye to pull the
vehicle from the snow, mud, sand,
or ditch. Tow eye threads may have
right or left-hand threads. Use caution
when installing or removing the
tow eye.
The vehicle must be in N (Neutral)
and the electric parking brake must be
released when loading the vehicle
onto a flatbed tow truck.
.If the vehicle is equipped with car
wash mode and has 12-volt battery
power, refer to “Car Wash Mode ”
under Automatic Transmission 0238
to place the vehicle in N (Neutral).
.If the 12-volt battery is dead and/or
the engine will not start, the vehicle
will not move. Try to jump start the
vehicle. Refer to Jump Starting -
North America 0379 and if the
jump start is successful, retry the
“Car Wash Mode ”procedure.
.If jump starting is unsuccessful, the
vehicle will not move. Tire skates or
dollies must be used under the
non-rolling tires to prevent vehicle
damage.
Front Attachment Points
The vehicle is equipped with specific
attachment points to be used by the
towing provider. These holes may be used to pull the vehicle from a flat
road surface onto the flatbed tow
truck.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle, such as behind a motor home.
The two most common types of
recreational vehicle towing are known
as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle
with all four wheels on the ground.
Dolly towing is towing the vehicle
with two wheels on the ground and
two wheels up on a device known as a
dolly.
Here are some important things to
consider before recreational vehicle
towing:
.Become familiar with the local laws
that apply to recreational vehicle
towing. These laws may vary by
region.
.The towing capacity of the towing
vehicle. Be sure to read the tow
vehicle manufacturer's
recommendations.

VEHICLE CARE 383
.How far the vehicle will be towed.
Some vehicles have restrictions on
how far and how long they can be
towed.
.The proper towing equipment. See
your dealer or trailering professional
for additional advice and equipment
recommendations.
.If the vehicle is ready to be towed.
Just as preparing the vehicle for a
long trip, make sure the vehicle is
prepared to be towed.
Caution
Use of a shield mounted in front of
the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would not
be covered by the vehicle warranty.
If using a shield, only use one that
attaches to the towing vehicle.
Dinghy Towing
Caution
If the vehicle is towed with all four
wheels on the ground, the
drivetrain components could be
damaged. The repairs would not be
covered by the vehicle warranty. Do
not tow the vehicle with all four
wheels on the ground.
The vehicle is neither designed nor
intended to be towed with all four
wheels on the ground. If the vehicle
must be towed, a dolly should be
used. See the following information on
dolly towing.
Dolly Towing
Driving onto a Dolly 1. Start the vehicle and drive onto the dolly.
2. Place the vehicle in P (Park).
3. Turn off the vehicle.
4. Open the hood.
5. Exit the vehicle and secure the vehicle onto the dolly.
6. Disconnect the negative (–) terminal connector from the
12-volt battery.
7. Close the hood of the vehicle.

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,
