104 Instruments and Controls
Antilock Brake System (ABS)
Warning Light
This light comes on briefly when the vehicle
is turned on to show that the light is
working. If it does not come on then, have
it fixed so it will be ready to warn you if
there is a problem.
If the ABS warning light stays on, or comes
on again while driving, the vehicle needs
service. A chime may also sound when the
light stays on.
If the ABS warning light is the only light on,
the vehicle has regular brakes, but ABS is
not functioning.
If both the ABS warning light and the brake
system warning light are on, ABS is not
functioning and there is a problem with the
regular brakes. See your dealer for service.
SeeBrake System Warning Light 0102.
Lane Keep Assist (LKA) Light
If equipped, the Lane Keep Assist Light may
display the following colors:
.Blank: LKA is disabled.
.White: Appears when the vehicle starts.
A steady white light indicates that LKA is
not ready to assist.
.Green: Appears when LKA is turned on
and ready to assist. LKA will gently turn
the steering wheel if the vehicle
approaches a detected lane marking.
.Amber: Appears when LKA is active. The
light flashes amber as a Lane Departure
Warning (LDW) alert to indicate that the
lane marking has been unintentionally
crossed. If the system detects you are
steering intentionally (to pass or change
lanes), the LDW alert may not display. LKA will not assist or alert if the turn signal
is active in the direction of lane departure,
or if LKA detects that you are accelerating,
braking, or actively steering. See
Lane Keep
Assist (LKA) (KEEP) 0230.
Vehicle Ahead Indicator
If equipped, this indicator will display green
when a vehicle is detected ahead and amber
when you are following a vehicle ahead
much too closely.

Driving and Operating 223
If the Park Assist System does not activate
due to a temporary condition, a system off
message is shown on the display. This can
occur under the following conditions:
.The driver has disabled the system.
.An object is currently blocking the rear
sensors (for example, bike rack, tailgate,
trailer hitch, etc.). Once the object is
removed, Park Assist will return to normal
operation.
.The bumper is damaged. Take the vehicle
to your dealer for repairs.
.Other conditions, such as vibrations from
a jackhammer or the compression of air
brakes on a very large truck, are affecting
system performance.
Rear Cross Traffic Alert (RCTA)
System
If equipped, Rear Cross Traffic Alert (RCTA)
displays a red warning triangle with a left
or right pointing arrow on the infotainment
display to warn of traffic coming from the
left or right. This system detects objects
coming from up to 20 m (65 ft) from the left
or right side of the vehicle. When an object
is detected, either three beeps sound from
the left or right or three Safety Alert Seatpulses occur on the left or right side,
depending on the direction of the detected
vehicle.
Driving With a Trailer
Use caution while backing up when towing
a trailer. The RCTA feature is automatically
disabled when a trailer is attached to the
vehicle.
Turning the Features On or Off
The
Xbutton on the center console is
used to turn on or off Rear Park Assist (RPA)
and RCTA at the same time. The indicator
light in the button comes on when the
features are on and turns off when the
features have been disabled.
RCTA can be turned on or off using the
infotainment system. To view available
settings for this feature, touch the Settings
icon on the infotainment home page. Select
“Vehicle” to display the list of available
options and select “Collision/Detection
Systems”.
Assistance Systems for Driving
If equipped, when driving the vehicle in a
forward gear, Forward Collision Alert (FCA),
Lane Departure Warning (LDW), Lane Keep
Assist (LKA), Side Blind Zone Alert (SBZA), Lane Change Alert (LCA), Automatic
Emergency Braking (AEB), and/or the Front
Pedestrian Braking (FPB) System can help to
avoid a crash or reduce crash damage.
Forward Collision Alert (FCA)
System
If equipped, the FCA system may help to
avoid or reduce the harm caused by
front-end crashes. When approaching a
vehicle ahead too quickly, FCA provides a
red flashing alert on the windshield and
rapidly beeps or pulses the driver seat. FCA
also lights an amber visual alert if following
another vehicle much too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 8 km/h (5 mph). If the vehicle
has Adaptive Cruise Control (ACC), it can
detect vehicles to distances of approximately
110 m (360 ft) and operates at all speeds.

from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
If LCA is disabled by the driver, the LCA
mirror displays will not light up.
When the System Does Not Seem to
Work Properly
The LCA system requires some driving for
the system to calibrate to maximum
performance. This calibration may occur
more quickly if the vehicle is driving on a
straight highway road with traffic and
roadside objects (e.g., guardrails, barriers).
LCA displays may not come on when
passing a vehicle quickly, for a stopped
vehicle, or when towing a trailer. The LCA
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
may alert to objects attached to the vehicle,
such as a trailer, bicycle, or object extending
out to either side of the vehicle. Attached
objects may also interfere with the
detection of vehicles. This is normal system
operation; the vehicle does not need service.
LCA may not always alert the driver to
vehicles in the next lane over, especially in
wet conditions or when driving on sharpcurves. 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 may not operate when the LCA 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" under
Exterior Care0307. If the
DIC still 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 displays do not light up when
moving vehicles are in the side blind zone or
are rapidly approaching this zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
Radio Frequency Information
See Radio Frequency Statement 0337.
Lane Keep Assist (LKA) (KEEP)
If equipped, LKA may help avoid crashes due
to unintentional lane departures. This
system uses a camera to detect lane
markings. The LKA may be ready to assist at speeds between 60 km/h (37 mph) and 180
km/h (112 mph). On some vehicles, the
system will instead operate above 50 km/h
(31 mph). LKA 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. 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. LKA can be overridden by turning
the steering wheel. If the system detects
you are steering intentionally across a lane
marker, the LDW will not be given. Do not
expect the LDW to occur when you are
intentionally crossing a lane marker.
{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.

Driving and Operating 231
Warning (Continued)
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 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 (Continued)
Warning (Continued)
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 on slippery roads could cause
loss of control of the vehicle and a crash.
Turn the system off.
{Warning
LKA will not alert the driver if a towed
trailer crosses into an adjacent lane of
travel. Serious injury or property damage
may occur if the trailer moves into
another lane. Always monitor the trailer
position while towing to make sure it is
within the same lane as the tow vehicle.
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. The system does not provide a Lane
Departure Warning (LDW) when
intentionally steering across a lane marker.
To turn LKA on and off, press
non the
center console. If equipped, the indicator
light on the button comes on when LKA is
on and turns off when LKA is disabled. On
some vehicles, a long press of over
three seconds is required to turn LKA off.
When on,
nis white, if equipped,
indicating that the system is not ready to
assist.
nis green if LKA is ready to assist.
LKA may assist by gently turning the
steering wheel if the vehicle approaches a
detected lane marking.
nis amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by flashing
namber 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.
