Rear Cross Traffic Braking (RCTB)
If equipped, RCTB displays a red warning
triangle with a left or right pointing arrow
on the infotainment screen to warn of
traffic coming from the left or right. The
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,
three beeps sounds from the left or right,
depending on the direction of the detected
vehicle. RCTB will bring the vehicle to a full
stop if a collision is imminent.
Driving With a Trailer
Use caution while backing up when towing
a trailer. RCTA and RCTB are automatically
disabled when a trailer is attached to the
vehicle.

Assistance Systems for Driving
If equipped, when driving the vehicle in a
forward gear, Forward Collision Alert (FCA),
Lane Keep Assist (LKA), Side Blind Zone Alert
(SBZA), Lane Change Alert (LCA), AutomaticEmergency 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 can detect vehicles to distances of
approximately 110 m (360 ft) and operates at
all speeds.
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of

Detecting the Vehicle Ahead
FCA warnings will not occur unless the FCA
system detects a vehicle ahead. When a
vehicle is detected, the vehicle ahead
indicator will display green. Vehicles may
not be detected on curves, highway exit
ramps, or hills, due to poor visibility; or if a
vehicle ahead is partially blocked by

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
settings. To view available settings from the
infotainment screen, touch Settings >
Vehicle > Collision/Detection Systems.
{Warning
Using AEB or IBA 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.
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 service.
Intersection Automatic Emergency
Braking (I-AEB) System
If equipped, the I-AEB system may help
avoid or reduce the harm caused by
front-end crashes with crossing vehicles,
or when performing a left-hand turn.
The system works when driving in a forward
gear above 15 km/h (9 mph) and less than
80 km/h (50 mph). It can detect oncoming
vehicles up to approximately 60 m (197 ft).
{Warning
I-AEB is an emergency crash preparation
feature. Do not rely on I-AEB to brake or
avoid crashes. I-AEB will not brake outside
of its operating speed range and only
responds to detected intersecting
vehicles. I-AEB may not:
.detect a crossing or oncoming vehicle
on winding or hilly roads.
.detect all vehicles, especially vehicles
with a trailer, tractors, muddy
vehicles, etc.
.detect a vehicle when weather limits
visibility, such as in fog, rain, or snow. (Continued)

blocked by pedestrians or other
objects.
Complete attention is always required
while driving, and you should be ready to
take action and apply the brakes and/or
steer the vehicle to avoid crashes.
Vehicle Crossing the Path Ahead
When there is a crossing vehicle detected
approaching from the right or the left side
that may lead to a collision, I-AEB provides a
red flashing alert on the windshield and
rapidly beeps or pulses the Safety Alert
Seat. See Advanced Driver Assistance
Systems 0223. I-AEB can provide a boost to
braking or automatically brake the vehicle.
Turning Left Across Oncoming Traffic
When the system detects that the vehicle is
turning left and there is risk for collision
with an oncoming vehicle, I-AEB provides a
red flashing alert on the windshield and
rapidly beeps or pulses the driver seat. I-AEB
can provide a boost to braking or
automatically brake the vehicle.
I-AEB can be set to Off, Alert, or Alert and
Brake. To view available settings from the
infotainment screen, touch Settings >
Vehicle > Collision/Detection Systems.
Crossing Traffic Alert
When your vehicle approaches an
intersecting vehicle too rapidly and there is
risk of a collision, a red warning graphic will
flash on the windshield. Also, eight rapid
high-pitched beeps will sound, or the driver
seat will pulse five times. The side of the seat that is pulsed and the location of the
beeps will depend on the direction that the
intersecting vehicle is detected from. When
this collision 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.

pedestrian or bicyclist is detected ahead.
When approaching a detected pedestrian or
bicyclist too quickly, FPB provides a red
flashing alert on the windshield and rapidly
beeps or pulses the driver seat. FPB can
provide a boost to braking or automatically
brake the vehicle. This system includes
Intelligent Brake Assist (IBA), and the
Automatic Emergency Braking (AEB) system
may also respond to pedestrians or
bicyclists. SeeAutomatic Emergency Braking
(AEB) 0235.
The FPB system can detect and alert to
pedestrians or bicyclists in a forward gear at
speeds between 8 km/h (5 mph) and
80 km/h (50 mph). During daytime driving,
the system detects pedestrians or bicyclists
up to a distance of approximately 40 m
(131 ft). During nighttime driving, system
performance is very limited.
{Warning
FPB does not provide an alert or
automatically brake the vehicle, unless it
detects a pedestrian. FPB may not detect
pedestrians, including children: (Continued)
Warning (Continued)
.When the pedestrian is not directly
ahead, fully visible, or standing
upright, or when part of a group.
.Due to poor visibility, including
nighttime conditions, fog, rain,
or snow.
.If the FPB sensor is blocked by dirt,
snow, or ice.
.If the headlamps or windshield are not
cleaned or in proper condition.
Be ready to take action and apply the
brakes. For more information, see
Defensive Driving 0164. Keep the
windshield, headlamps, and FPB sensor
clean and in good repair.
FPB can be set to Off, Alert, or Alert and
Brake through vehicle settings. To view
available settings from the infotainment
screen, touch Settings > Vehicle > Collision/
Detection Systems.
Detecting the Pedestrian Ahead
FPB alerts and automatic braking will not
occur unless the FPB system detects a
pedestrian or bicyclist. When a pedestrian or
bicyclist that may enter the vehicle’s
forward path is detected, the pedestrian
ahead indicator will display amber.

240 Driving and Operating
Without Head-Up Display
When the vehicle approaches a pedestrian
or bicyclist 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 or bicyclist 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 or bicyclist crashes or
reduce pedestrian injury. FPB can automatically brake to detected pedestrians
or bicyclists or bicyclists 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 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 or bicyclists,
including shadows. This is normal
operation 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 settings.To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems >
Front Pedestrian Detection.
{Warning
Using AEB or IBA 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.
Side Blind Zone Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists drivers with
avoiding crashes that occur with moving
vehicles in the side blind zone, or blind spot
areas. 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 and
a vehicle is also detected on the same side,
the display will flash as an extra warning
not to change lanes. Since this system is
part of the Lane Change Alert (LCA) system,
read the entire LCA section before using this
feature.

Driving and Operating 241
Lane Change Alert (LCA)
If equipped, the LCA system is a
lane-changing aid that assists drivers with
avoiding lane change crashes that occur with
moving vehicles in the side blind zone (or
spot) areas or with vehicles rapidly
approaching these areas from behind. The
LCA warning display will light up in the
corresponding outside mirror and will flash
if the turn signal is on.
Side Blind Zone Alert (SBZA) is included as
part of the LCA system.
{Warning
LCA does not alert the driver to vehicles
outside of the system detection zones,
pedestrians, 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.LCA Detection Zones
1. SBZA Detection Zone
2. LCA Detection Zone
The LCA sensor covers a zone of
approximately one lane over from both
sides of the vehicle, or 3.5 m (11 ft). The
height of the zone is approximately between
0.5 m (1.5 ft) and 2 m (6 ft) off the ground.
The Side Blind Zone Alert (SBZA) warning
area starts at approximately the middle of
the vehicle and goes back 5 m (16 ft). Drivers
are also warned of vehicles rapidly
approaching from up to 70 m (230 ft) behind
the vehicle.
How the System Works
The LCA symbol lights up in the side 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 Side Mirror
DisplayRight Side 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
side 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 through vehicle
personalization.To view available settings

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 driven 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 or for a stopped
vehicle. LCA may alert to objects attached to
the vehicle, such as a 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 Care0321. 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
rapidly approaching this zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
Driving with a Trailer
If equipped with Lane Change Alert (LCA),
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.
Side Bicycle Detection
If equipped, the system may detect a
bicyclist approaching from the side or rear
of the vehicle. If this occurs, a chime will sound in the
direction of the detection, and the Safety
Alert Seat will pulse if enabled through
vehicle settings. To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
Bicyclist Detection is available when the
vehicle is in D (Drive), P (Park), and for a
short time after the vehicle is turned off.
If the vehicle detects a bicyclist when it is
off, a DIC message may display and alert to
the direction of the detection. In some
cases, an Unavailable message may display.
This is normal and does not mean that the
system is broken.
Detection Zones
When the vehicle is in P (Park) or is turned
off, a bicyclist can be detected 11 m (36 ft)
behind the vehicle or 10 m (33 ft) to the
side of the vehicle.
When the vehicle is in D (Drive), a bicyclist
can be detected 3 m (10 ft) behind the
vehicle or to the side of the vehicle.

Turning the Feature On or Off
Bicyclist Detection can be turned on or off
through vehicle settings. To view available
settings from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.
Blind Zone Steering Assist (BZSA)
If equipped, the Blind Zone Steering Assist
(BZSA) system can detect a potential crash
with a moving vehicle in the lane you are
entering. It provides a brief, urgent turn of
the steering wheel to alert you to take
action to avoid a collision.
BZSA works with the Lane Keep Assist (LKA).
BZSA operates when the vehicle is in a
forward gear, and only when LKA is enabled
and able to assist. SeeLane Keep Assist
(LKA) 0245.
BZSA will provide a steering correction when
your vehicle is about to leave the current
lane of travel, with the possibility of a
collision with a vehicle in the adjacent lane.
This steering correction happens closer to
the center of the lane and has a stronger
steering correction than LKA. Unlike LKA, the
steering correction with BSZA will happen
even if your turn signal is on in the
direction of lane departure. In addition to the BZSA steering
intervention, the
Awill turn amber, six
beeps or six seat pulses will occur,
if equipped with Safety Alert Seat, and
8or|will flash on the outside
rear view mirror.
{Warning
Do not rely on Blind Zone Steering Assist
(BZSA) to prevent crashes. This system
does not replace the need to pay
attention and drive safely. Failure to use
proper care when driving may result in
vehicle damage, injury, or death.
.BZSA performance may be affected by
weather and road conditions.
.BZSA does not provide steering
assistance to avoid a vehicle that is in,
or has entered, your lane of travel.
.BZSA will not prevent a towed trailer
from crossing into the adjacent lane.
Always monitor the trailer position
while towing to ensure it is in the
same lane as your vehicle. BZSA is
only designed to detect when your
vehicle unintentionally crosses
detected lane lines.
Traffic Sign Assistant
If equipped, Traffic Sign Assistant recognizes
designated traffic signs via the front camera
located behind the windshield in front of the
interior rear view mirror, and displays the
detected speed limit in the Driver
Information Center (DIC). Additionally, speed
limit information from the navigation
system map database may be used.
Caution
The system is intended to assist the
driver within a defined speed range to
discern certain traffic signs. Always pay
attention to posted speed limit signs.
Do not ignore traffic signs which are not
displayed by the system.
The system does not discern any signs
other than the conventional traffic signs
that might give or end a speed limit.
It may not detect some electronic speed
signs.
