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
light will flash on the instrument
cluster. Reduce vehicle speed by
gradually removing your foot from
the accelerator. If trailer sway
continues, StabiliTrak/ESC can
reduce engine torque to help slow
the vehicle. TSC will not function ifStabiliTrak/ESC is turned off. See
Traction Control/Electronic Stability
Control
0208.
{Warning
Trailer sway can result in a crash
and in serious injury or death,
even if the vehicle is equipped
with TSC.
If the trailer begins to sway,
reduce vehicle speed by
gradually removing your foot from
the accelerator. Then pull over to
check the trailer and vehicle to
help correct possible causes,
including an improperly or
overloaded trailer, unrestrained
cargo, improper trailer hitch
configuration, or improperly
inflated or incorrect vehicle or
trailer tires. See Towing
Equipment 0251 for trailer ratings
and hitch setup
recommendations.
Trailer Tires
Special Trailer (ST) tires differ from
vehicle tires. Trailer tires are
designed with stiff sidewalls to help
prevent sway and to support heavy
loads. These features can make it
difficult to determine if the trailer tire
pressures are low only based on a
visual inspection.
Always check all trailer tire
pressures before each trip when the
tires are cool. Low trailer tire
pressure is a leading cause of trailer
tire blowouts.
Trailer tires deteriorate over time.
The trailer tire sidewall will show the
week and year the tire was
manufactured. Many trailer tire
manufacturers recommend
replacing tires more than six
years old.
Overloading is another leading
cause of trailer tire blowouts. Never
load your trailer with more weight
than the tires are designed to
support. The load rating is on the
trailer tire sidewall.

256 Driving and Operating
Always know the maximum speed
rating for the trailer tires before
driving. This may be significantly
lower than the vehicle tire speed
rating. The speed rating may be on
the trailer tire sidewall. If the speed
rating is not shown, the default
trailer tire speed rating is 105 km/h
(65 mph).Conversions and

{Warning
The Data Link Connector (DLC) is
used for vehicle service and
Emission Inspection/Maintenance
testing. SeeMalfunction
Indicator Lamp (Check Engine
Light) 0135. A device connected
to the DLC —such as an
aftermarket fleet or
driver-behavior tracking device —
may interfere with vehicle
systems. This could affect vehicle
operation and cause a crash.
Such devices may also access
information stored in the vehicle’s
systems.
Caution
Some electrical equipment can
damage the vehicle or cause
components to not work and
would not be covered by the
vehicle warranty. Always check
with your dealer before adding
electrical equipment.
Add-on equipment can drain the
vehicle's 12-volt battery, even if the
vehicle is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see

Vehicle 089 and

Vehicle Care 335
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty. Do not lash
or hook to suspension
components. Use the proper
straps around the tires to secure
the vehicle. Do not drag a locked
wheel/tire while loading the
vehicle. Do not use a sling type
lift to tow the vehicle. This could
damage the vehicle.
GM recommends a flatbed tow truck
to transport a disabled vehicle. Use
ramps to help reduce approach
angles, if necessary. A towed
vehicle should have its drive wheels
off the ground. Contact Roadside
Assistance or a professional towing
service if the disabled vehicle must
be towed.
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:
.
Before towing the vehicle,
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.
. 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.

CRC - 3/11/19
336 Vehicle Care
.Whether 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
These vehicles may be dinghy
towed from the front. These vehicles
can also be towed by placing them
on a platform trailer with all four
wheels off the ground. Also see the
information on dolly towing later in
this section.
For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to be towed and secure it to the
towing vehicle.
2. Start the vehicle.
3. Shift the transmission to N (Neutral).
4. Put the vehicle into ACCESSORY Mode by
pressing ENGINE START/
STOP one time without the brake pedal applied. An amber
light will appear in the button
when in ACCESSORY Mode.
See
Ignition Positions 0192.
The chime will ring
continuously for 30 minutes.
Leave the transmission in
N (Neutral).
5. Turn off all accessories that are not needed.
It is required to charge the battery of
the towed vehicle during
recreational vehicle towing.
Caution
If the vehicle is towed without
performing each of the steps
listed under “Dinghy Towing,” the
automatic transmission and AWD
system could be damaged. Be
sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.

Service and Maintenance 349
The Tire Rotation and Required
Services are the responsibility of the
vehicle owner. It is recommended to
have your dealer perform these
services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions.
Because of the way people use
vehicles, maintenance needs vary.
There may need to be more
frequent checks and services. The
Additional Required Services -
Normal are for vehicles that:
.Carry passengers and cargo
within recommended limits on
the Tire and Loading Information
label. See Vehicle Load Limits
0 188.
. Are driven on reasonable road
surfaces within legal driving
limits.
. Use the recommended fuel. See
Recommended Fuel 0240. Refer to the information in the
Maintenance Schedule Additional
Required Services - Normal chart.
The Additional Required Services -
Severe are for vehicles that are:
.
Mainly driven in heavy city traffic
in hot weather.
. Mainly driven in hilly or
mountainous terrain.
. Frequently towing a trailer.
. Used for high speed or
competitive driving.
. Used for taxi, police, or delivery
service.
Refer to the information in the
Maintenance Schedule Additional
Required Services - Severe chart.{Warning
Performing maintenance work can
be dangerous and can cause
serious injury. Perform
maintenance work only if the
required information, proper tools,
and equipment are available.
If they are not, see your dealer to
have a trained technician do the
work. See Doing Your Own
Service Work 0259.
