326 DRIVING AND OPERATING
Take Steering
The LKA system does not
continuously steer the vehicle. If LKA
does not detect active driver steering,
an alert and chime may be provided.
Steer the vehicle to dismiss. LKA may
become temporarily unavailable after
repeated take steering alerts.
When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
.Sudden lighting changes, such as
when driving through tunnels.
.Banked roads.
.Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the windshield
may help.
A camera blocked message may
display if the camera is blocked. Some
driver assistance systems may have
reduced performance or not work at
all. An LKA or LDW unavailable message may display if the systems
are temporarily unavailable. This
message could be due to a blocked
camera. The LKA system does not
need service. Clean the outside of the
windshield behind the rearview mirror.
LKA assistance and/or LDW alerts
may occur due to tar marks, shadows,
cracks in the road, temporary or
construction lane markings, or other
road imperfections. This is normal
system operation; the vehicle does not
need service. Turn LKA off if these
conditions continue.

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

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

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.

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

Warning (Continued)
(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).
Trailering App
Trailer Lights App
If equipped, the Trailer Lights App is
