Tires
.Do not tow a trailer while using a
compact spare tire on the vehicle.
.Tires must be properly inflated to
support loads while towing a trailer.
SeeTires 0393 for instructions on
proper tire inflation.
Safety Chains
Always attach chains between the
vehicle and the trailer, and attach the
chains to the holes on the trailer hitch
platform. Instructions about safety
chains may be provided by the hitch
manufacturer or by the trailer
manufacturer. If the trailer being towed weighs up to
2 271 kg (5,000 lb) with a
factory-installed step bumper, safety
chains may be attached to the
attaching points on the bumper;
otherwise, safety chains should be
attached to holes on the trailer hitch.
Cross the safety chains under the
tongue of the trailer to help prevent
the tongue from contacting the road if
it becomes separated from the hitch.
Always leave just enough slack so the
combination can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
Loaded trailers over 900 kg (2,000 lb)
must be equipped with brake systems
and with brakes for each axle. Trailerbraking equipment conforming to
Canadian Standards Association (CSA)
requirement CAN3-D313, or its
equivalent, is recommended.
State or local regulations may require
trailers to have their own braking
system if the loaded weight of the
trailer exceeds certain minimums that
can vary from state to state. Read and
follow the instructions for the trailer
brakes so they are installed, adjusted,
and maintained properly. Never
attempt to tap into your vehicle's
hydraulic brake system. If you do,
both the vehicle anti-lock brakes and
the trailer brakes may not function,
which could result in a crash.

Trailer Wiring Harness
The seven-pin trailer connector is
mounted in the bumper. This
connector can be plugged into a
seven-pin universal heavy-duty trailer
connector available through your
dealer.
Use only a round, seven-wire
connector with flat blade terminals
meeting SAE J2863 specifications for
proper electrical connectivity.
The seven-wire harness contains the
following trailer circuits:
.Yellow/Grey: Left Stop/Turn Signal
.Green/Violet: Right Stop/Turn
Signal
.Grey/Brown: Taillamps
.White: Ground
.White/Green: Back-up Lamps
.Red/Green: Battery Feed
.Dark Blue: Trailer Brake
To help charge a remote (non-vehicle)
battery, change drive mode to Tow
Haul. If the trailer is too light for Tow/
Haul Mode, turn on the headlamps to
help charge the battery.
Electric Brake Control Wiring
Provisions
These wiring provisions are included
with the vehicle as part of the trailer
wiring package. These provisions are
for an electric brake controller.
The harness should be installed by
your dealer or a qualified service
center.
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.
Trailer Lamps
Always check all trailer lamps are
working at the beginning of each trip,
and periodically on longer trips.
If equipped, the Trailering App will
monitor the RH turn/brake lamp
circuit, LH turn/brake lamp circuit,
running lamp circuit, and reverse
lamp circuits on the trailer. DIC
messages and Trailering App alerts
may be displayed if lighting circuit
issues are detected on the trailer. Pressing START LIGHT TEST in the
Trailering App automatically activates
trailer lamps. The Trailering App is
not a substitute for manually
inspecting your trailer lamps. See
Trailering App
0349.
Trailer Connection and Lamp
Messages
When a trailer is properly connected
and working, no trailer connection or
lamp messages appear on the Driver
Information Center (DIC). However; if
the vehicle detects an issue with a
trailer connection or lamp, you may
see the following DIC message(s):
.TRAILER DISCONNECTED CHECK
CONNECTION appears when a
connected trailer is disconnected.
It appears immediately when the
vehicle is on, or upon the next
start-up if the trailer was
disconnected while the vehicle was
off. Check the trailer connection as
appropriate.
.CHECK TRAILER XXX LAMP
appears when there is a detected
lamp or wiring fault on the trailer.

344 DRIVING AND OPERATING
Turn Signals When Towing a
Trailer
When properly connected, the trailer
turn signals should 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.
Tow/Haul Mode
For instructions on how to enter Tow/
Haul mode, seeTow/Haul Mode0256.
Tow/Haul assists when pulling a
heavy trailer or a large or heavy load.
Tow/Haul Mode is designed to be
most effective when the vehicle and
trailer combined weight is at least
75% of the vehicle's Gross Combined
Weight Rating (GCWR). See
“Maximum Trailer Weight ”under
Trailer Towing 0334.
Tow/Haul Mode is most useful when
towing a heavy trailer or carrying a
large or heavy load:
.through rolling terrain
.in stop-and-go traffic
.in busy parking lots
Operating the vehicle in Tow/Haul
Mode when lightly loaded or not
towing will not cause damage;
however, it is not recommended and
may result in unpleasant engine and
transmission driving characteristics
and reduced fuel economy.
Integrated Trailer Brake Control
System
The vehicle may have an Integrated
Trailer Brake Control (ITBC) system
for use with electric trailer brakes or
most electric over hydraulic trailer
brake systems. These instructions
apply to both types of electric trailer
brakes.
This symbol is on the Trailer Brake
Control Panel on vehicles with an
ITBC system. The power output to the
trailer brakes is proportional to the amount of vehicle braking. This
available power output to the trailer
brakes can be adjusted to a wide
range of trailering situations.
The ITBC system is integrated with
the vehicle’s brake, anti-lock brake,
and StabiliTrak/Electronic Stability
Control (ESC) systems. In trailering
conditions that cause the vehicle’s
anti-lock brake or StabiliTrak/ESC
systems to activate, power sent to the
trailer's brakes will be automatically
adjusted to minimize trailer wheel
lock-up. This does not imply that the
trailer has StabiliTrak/ESC.
If the vehicle’s brake, anti-lock brake,
or StabiliTrak systems are not
functioning properly, the ITBC system
may not function fully or at all. Make
sure all of these systems are fully
operational to allow the ITBC system
to function properly.
The ITBC system is powered through
the vehicle's electrical system. Turning
the ignition off will also turn off the
ITBC system. The ITBC system is fully
functional only when the ignition is in
ON/RUN.

Connecting a trailer that has an air
brake system may result in reduced
or complete loss of trailer braking,
including increased stopping
distance or trailer instability which
could result in serious injury, death,
or property damage. Only use the
ITBC system with electric or electric
over hydraulic trailer brake systems.

conditions change.
{Warning
Trailer brakes that are over-gained
or under-gained may not stop the
vehicle and the trailer as intended
and can result in a crash. Always
follow the instructions to set the
Trailer Gain for the proper trailer
stopping performance.
To adjust Trailer Gain for each towing
condition: 1. Drive the vehicle with the trailer attached on a level road surface
representative of the towing
condition and free of traffic at
about 32 to 40 km/h (20 to 25 mph)
and fully apply the Manual Trailer
Brake apply lever.
Note
Adjusting Trailer Gain at speeds lower
than 32 to 40 km/h (20 to 25 mph)
may result in an incorrect gain
setting. 2. Adjust the Trailer Gain, using the Trailer Gain adjustment buttons, to
just below the point of trailer wheel lock-up, indicated by trailer
wheel squeal or tire smoke when a
trailer wheel locks.
Note
Trailer wheel lock-up may not occur if
towing a heavily loaded trailer. In this
case, adjust the Trailer Gain to the
highest allowable setting for the
towing condition. 3. Readjust Trailer Gain any time vehicle loading, trailer loading,
or road surface conditions change
or if trailer wheel lock-up is
noticed at any time while towing.

the trailer is not covered under the
vehicle warranty. Contact your trailer
dealer for assistance with trailer
repairs and trailer warranty
information.
Trailer Sway Control (TSC)
Vehicles with StabiliTrak/Electronic
Stability Control (ESC) have a Trailer
Sway Control (TSC) feature. Trailer
sway 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 may
also apply the trailer brakes.
Cadillac Escalade Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13690472) - 2021 - CRC - 8/10/21
348 DRIVING AND OPERATING
If TSC is enabled, the Traction Control
System (TCS)/StabiliTrak warning
light will flash on the instrument
cluster. Reduce vehicle speed by
gradually removing your foot from the
accelerator. If trailer sway continues,
StabiliTrak can help slow the vehicle
down. TSC will not function if
StabiliTrak is turned off. SeeTraction
Control/Electronic Stability Control
0 264.
{Warning
Trailer sway can result in a crash
and in serious injury or death, even
if the vehicle is equipped with TSC.
(Continued)
Warning (Continued)
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. SeeTowing Equipment
0 338 for trailer ratings and hitch
setup recommendations.
Aftermarket Electronic Trailer
Sway Control Devices
Some trailers may come equipped
with an electronic device designed to
reduce or control trailer sway.
Aftermarket equipment manufacturers
also offer similar devices that connect
to the wiring between the trailer and
the vehicle. These devices may
interfere with the vehicle’s trailer
brake systems or other systems,
including integrated anti-sway
systems, if equipped. Messages related to trailer connections or trailer brakes
could appear on the DIC. The effects
of these aftermarket devices on
vehicle handling or trailer brake
performance is not known.
{Warning
Use of aftermarket electronic trailer
sway control devices could result in
reduced trailer brake performance,
loss of trailer brakes, or other
malfunctions, and result in a crash.
You or others could be seriously
injured or killed. Before using one
of these devices:
.Ask the device or trailer
manufacturer if the device has
been thoroughly tested for
compatibility with the make,
model, and year of your vehicle
and any optional equipment
installed on your vehicle.
.Before driving, check the trailer
brakes are working properly,
if equipped. Drive the vehicle
with the trailer attached on a
level road surface that is free of
traffic at about 32-40 km/h

(20-25 mph) and fully apply the
manual trailer brake apply lever.
Also, check the trailer brake
lamps and other lamps are
functioning correctly.
.If the trailer brakes are not
operating properly at any time,
or if a DIC message indicates
problems with the trailer
connections or trailer brakes,
carefully pull the vehicle over to
the side of the road when traffic
conditions allow.
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 blow-outs.If the vehicle is equipped with a trailer
tire pressure monitoring system, see
the trailer tire pressure monitoring
system description and the
trailering app.
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 blow-outs. Never load
your trailer with more weight than the
tires are designed to support. The load
rating is located on the trailer tire
sidewall.
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).
