bicyclists, or animals. It may not
provide alerts when changing lanes
under all driving conditions. Failure
to use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before making a
lane change, always check mirrors,
glance over your shoulder, and use
the turn signals.
ESBZA Detection Zones
1. SBZA Detection Zone
2. ESBZA Detection Zone
3. LCA Detection Zone
The Side Blind Zone Alert (SBZA)
warning area starts at approximately
the middle of the vehicle and goes
back 5 m (16 ft). The Extended Side
Blind Zone Alert (ESBZA) warning
area starts at approximately 3 m (10 ft) to the trailing edge of the
vehicle and goes back up to 21 m
(69 ft) behind the vehicle. The
maximum trailer length is 12 m (39 ft).
How the System Works
The LCA/ESBZA symbol lights up in
the side mirrors when the system
detects a moving vehicle in the next
lane over that is in the extended side
blind zone. This indicates it may be
unsafe to change lanes. Before making
a lane change, check the SBZA
display, check mirrors, glance over
your shoulder, and use the turn
signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror LCA/ESBZA displays
will briefly come on to indicate the
system is operating. When the vehicle
is in a forward gear, the left- or right-side mirror display will light up
if a moving vehicle is detected in that
blind zone. If the turn signal is
activated in the same direction as a
detected vehicle, this display will flash
as an extra warning not to change
lanes.
LCA/ESBZA displays may not come on
when passing a vehicle quickly,
or when passing a stopped vehicle.
LCA/ESBZA may alert to objects
attached to the vehicle, such as a
bicycle, or object extending out to
either side of the vehicle or trailer.
This is normal system operation; the
vehicle does not need service.
LCA/ESBZA can be disabled through
vehicle personalization. See
“Collision/
Detection Systems” underVehicle
Personalization 0138. If SBZA is
disabled by the driver, the ESBZA
mirror displays will not light up.
When the System Does Not
Seem to Work Properly
LCA/ESBZA displays may not come on
when passing a vehicle quickly,
or when passing a stopped vehicle.
The LCA/ESBZA detection zones that

extend back from the side of the
vehicle do not move further back
when a trailer is towed. Use caution
while changing lanes when towing a
trailer. LCA/ESBZA may alert to
objects attached to the vehicle, such
as a trailer, bicycle, or object
extending out to either side of the
vehicle or trailer. This is normal
system operation; the vehicle does not
need service.
LCA/ESBZA may not always alert the
driver to vehicles in the side blind
zone, especially in wet conditions. The
system does not need to be serviced.
The system may light up due to
guardrails, signs, trees, shrubs, and
other non-moving objects. This is
normal system operation; the vehicle
does not need service.
LCA/ESBZA may not operate when the
LCA/ESBZA sensors in the left or right
corners of the rear bumper are
covered with mud, dirt, snow, ice,
or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing
the Vehicle" underExterior Care0432.
If the DIC displays the system
unavailable message after cleaning both sides of the vehicle toward the
rear corners of the vehicle, see your
dealer.
If the DIC displays the system
unavailable message after cleaning
both sides of the vehicle toward the
rear corners of the vehicle, see your
dealer
If the LCA/ESBZA displays do not
light up when vehicles are in the blind
zone and the system is clean, the
system may need service. Take the
vehicle to your dealer.
When ESBZA is disabled for any
reason other than the driver turning it
off, the Extended Side Blind Zone
Alert On option will not be available
on the personalization menu.
Driving with a Trailer
Although this system is intended to
help drivers avoid lane change
crashes, it does not replace driver
vision and therefore should be
considered a lane change aid. Even
with the ESBZA system, the driver
must check carefully for objects
outside of the reporting zone (e.g., a
fast approaching vehicle) or vehicle
along the side of the trailer before
changing lanes.
Use caution while changing lanes
when towing a trailer.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. This system uses a camera
to detect lane markings between
60 km/h (37 mph) and 180 km/h
(112 mph). It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking. It may also provide a Lane
Departure Warning (LDW) alert if the
vehicle crosses a detected lane
marking. LKA can be overridden by
turning the steering wheel. This
system is not intended to keep the
vehicle centered in the lane. LKA will
not assist and alert if the turn signal
is active in the direction of lane
departure, or if it detects that you are
accelerating, braking or actively
steering.

DRIVING AND OPERATING 325
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a lane
marking is detected.
The LKA and LDW systems
may not:
.Provide an alert or enough
steering assist to avoid a lane
departure or crash.
.Detect lane markings under poor
weather or visibility conditions.
This can occur if the windshield
or headlamps are blocked by dirt,
snow, or ice; if they are not in
proper condition; or if the sun
shines directly into the camera.
.Detect road edges.
.Detect lanes on winding or hilly
roads.
If LKA only detects lane markings
on one side of the road, it will only
assist or provide an LDW alert (Continued)
Warning (Continued)
when approaching the lane on the
side where it has detected a lane
marking. Even with LKA and LDW,
you must steer the vehicle. Always
keep your attention on the road and
maintain proper vehicle position
within the lane, or vehicle damage,
injury, or death could occur. Always
keep the windshield, headlamps,
and camera sensors clean and in
good repair. Do not use LKA in bad
weather conditions or on roads with
unclear lane markings, such as
construction zones.
{Warning
Using LKA while towing a trailer or
on slippery roads could cause loss
of control of the vehicle and a
crash. Turn the system off.
How the System Works
LKA uses a camera sensor installed on
the windshield ahead of the rearview
mirror to detect lane markings. It may provide brief steering assist if it
detects an unintended lane departure.
It may further provide an audible alert
or the driver seat may pulse indicating
that a lane marking has been crossed.
To turn LKA on and off, press
Aon
the center console. If equipped, the
indicator light on the button comes
on when LKA is on and turns off
when LKA is disabled.
When on,
Ais white, if equipped,
indicating that the system is not
ready to assist.
Ais green if LKA is
ready to assist. LKA may assist by
gently turning the steering wheel if
the vehicle approaches a detected
lane marking.
Ais amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by
flashing
Aamber if the vehicle
crosses a detected lane marking.
Additionally, there may be three
beeps, or the driver seat may pulse
three times, on the right or left,
depending on the lane departure
direction.

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).
