Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Objects Not Directly in Front of Your
Vehicle
The detection of objects in front of
the vehicle may not be possible if:
.The vehicle or object ahead is not
within your lane.
. The vehicle ahead is shifted, not
centered, or is shifted to one side
of the lane. Driving in Narrow Lanes
Vehicles in adjacent traffic lanes or
roadside objects may be incorrectly
detected when located along the
roadway.
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. ACC will
not detect a vehicle in the lane while
driving on steep hills. If the brakes are
applied, ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
.
Step lightly on the brake pedal
. Press

Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if the
ignition is turned off.
Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror can
become blocked by snow, ice, dirt,
mud, or debris. This area needs to be
cleaned for ACC to operate properly.
The vehicle headlamps may need to
be cleaned due to dirt, snow, or ice.
Objects that are not illuminated
correctly may be difficult to detect.
If ACC will not operate, regular cruise
control may be available. See
“Switching Between ACC and Regular
Cruise Control ”previously in this
section. Always consider driving
conditions before using either cruise
control system.

while backing.
If the brake pedal is not pressed soon
after the stop, the Electric Parking
Brake (EPB) may be set. When it is
safe, press the accelerator pedal firmly
at any time to override RAB.
{Warning
There may be instances where
unexpected or undesired automatic
braking occurs. If this happens,
either press the brake pedal or
firmly press the accelerator pedal to
release the brakes from the RAB
system. Before releasing the brakes,
check the RVC and check the area
around the vehicle to make sure it
is safe to proceed. Rear Cross Traffic Alert (RCTA)
If equipped, RCTA displays a red
warning triangle with a left or right
pointing arrow 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 Seat pulses occur on the
left or right side, depending on the
direction of the detected vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from
the back of the vehicle do not move
further back when a trailer is towed.
See
Radio Frequency Statement 0330.
Turning the Features On or Off
TouchXon the center stack to turn
on or off the Front and Rear Park
Assist, Reverse Automatic Braking
(RAB), and the Backing Warning
System at the same time. The
indicator light next to the button comes on when the features are on
and turns off when the features have
been disabled.
Turn off Park Assist, RCTA, and RAB
when towing a trailer.
To turn the RPA symbols or guidance
lines (on some models) on or off, see
“Rear Camera Park Assist Symbols”

RCTA can also be turned on or off
through vehicle personalization. See
“Collision/Detection Systems” under
Vehicle Personalization 0116.
Rear Pedestrian Alert
Under certain conditions, this feature
can provide alerts for a pedestrian
within the system’s range directly
behind the vehicle. This feature only
works in R (Reverse) below 12 km/h
(8 mph), and detects pedestrians up to
8 m (26 ft) away during daytime
driving. During nighttime driving,
feature performance is very limited.

AEB may slow the vehicle to a
complete stop to try to avoid a
potential crash. If this happens, AEB
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
Release the EPB or firmly press the
accelerator pedal.
{Warning
AEB may automatically brake the
vehicle suddenly in situations
where it is unexpected and
undesired. It could respond to a
turning vehicle ahead, guardrails,
signs, and other non-moving
objects. To override AEB, firmly
press the accelerator pedal, if it is
safe to do so.
Intelligent Brake Assist (IBA)
IBA may activate when the brake
pedal is applied quickly by providing a
boost to braking based on the speed
of approach and distance to a vehicle
ahead.Minor brake pedal pulsations or pedal
movement during this time is normal
and the brake pedal should continue
to be applied as needed. IBA will
automatically disengage only when
the brake pedal is released.
{Warning
IBA may increase vehicle braking in
situations when it may not be
necessary. You could block the flow
of traffic. If this occurs, take your
foot off the brake pedal and then
apply the brakes as needed.
AEB and IBA can be disabled through
vehicle personalization. See “Collision/
Detection Systems” underVehicle
Personalization 0116.
{Warning
Using AEB or IBA while towing a
trailer could cause you to lose
control of the vehicle and crash.
(Continued)
Warning (Continued)
Turn the system to Alert, or if the
vehicle has ACC to Off, when
towing a trailer.
A system unavailable message may
display if:
. The front of the vehicle or
windshield is not clean.
. Heavy rain or snow is interfering
with object detection.
. There is a problem with the
StabiliTrak/Electronic Stability
Control (ESC) system.
The AEB system does not need

Front Pedestrian Braking
(FPB) System
If equipped, the FPB system may help
avoid or reduce the harm caused by
front-end crashes with nearby
pedestrians when driving in a forward
gear. FPB displays an amber indicator,
~, when a nearby pedestrian is

216 DRIVING AND OPERATING
Without Head-Up Display
When the vehicle approaches a
pedestrian ahead too rapidly, the red
FPB alert display will flash on the
windshield. Eight rapid high-pitched
beeps will sound from the front,
or both sides of the Safety Alert Seat
will pulse five times. When this
Pedestrian Alert occurs, the brake
system may prepare for driver braking
to occur more rapidly which can cause
a brief, mild deceleration. Continue to
apply the brake pedal as needed.
Cruise control may be disengaged
when the Front Pedestrian Alert
occurs.
Automatic Braking
If FPB detects it is about to crash into
a pedestrian directly ahead, and the
brakes have not been applied, FPB
may automatically brake moderately
or brake hard. This can help to avoid some very low speed pedestrian
crashes or reduce pedestrian injury.
FPB can automatically brake to
detected pedestrians between 8 km/h
(5 mph) and 80 km/h (50 mph).
Automatic braking levels may be
reduced under certain conditions,
such as higher speeds. If also
equipped with the Night Vision
system, pedestrians detected by the
Night Vision system will not cause
automatic braking to occur.
If this happens, Automatic Braking
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
Release the EPB. A firm press of the
accelerator pedal will also release
Automatic Braking and the EPB.
{Warning
FPB may alert or automatically
brake the vehicle suddenly in
situations where it is unexpected
and undesired. It could falsely alert
or brake for objects similar in shape
or size to pedestrians, including
shadows. This is normal operation
(Continued)
Warning (Continued)
and the vehicle does not need
service. To override Automatic
Braking, firmly press the accelerator
pedal, if it is safe to do so.
Automatic Braking can be disabled
through vehicle personalization. See
“Front Pedestrian Detection ”in
“Collision/Detection Systems” under
Vehicle Personalization 0116.
{Warning
Using the Front Pedestrian Braking
system while towing a trailer could
cause you to lose control of the
vehicle and crash. Turn the system
to Alert or Off when towing a
trailer.
Cleaning the System
If FPB does not seem to operate
properly, cleaning the outside of the
windshield in front of the rearview
mirror may correct the issue.

218 DRIVING AND OPERATING
How the System Works
The LCA symbol lights up in the
outside mirrors when the system
detects a moving vehicle in the next
lane over that is in the side blind zone
or rapidly approaching that zone from
behind. A lit LCA symbol indicates it
may be unsafe to change lanes. Before
making a lane change, check the LCA
display, check mirrors, glance over
your shoulder, and use the turn
signals.
Left Outside MirrorDisplayRight Outside
Mirror Display
When the vehicle is started, both
outside mirror LCA displays will
briefly come on to indicate the system
is operating. When the vehicle is in a
forward gear, the left or right outside
mirror display will light up if a moving
vehicle is detected in the next lane
over in that blind zone or rapidly
approaching that 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 can be disabled. When you
disable LCA, Side Blind Zone Alert is
also disabled. See
“Collision/Detection
Systems” underVehicle Personalization
0 116. 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 sharp curves. 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 Care0293.
