Park Assist
The vehicle may be equipped with Front and
Rear Park Assist (FRPA). Under certain
conditions, the Park Assist system can assist
the driver during backing and parking maneuvers when the vehicle is driven at no
more than 9 km/h (6 mph). An illuminated
indicator in the Park Assist button indicates
the system is ready.
Sensors located in the bumpers measure the
distance between the vehicle and objects
using sonar technology. These sensors are
designed to detect certain objects up to
1.8 m (6 ft) behind and 1.2 m (4 ft) in front of
your vehicle that are taller than
25 cm (10 in).
Different environmental conditions may
affect whether and how far the Park Assist
system can detect objects. Keep the sensors
clean of mud, dirt, snow, ice, and slush; and
clean sensors after a car wash in freezing
temperatures. Sensors that are not clean
may not detect objects or may cause the
system to alert when not required.
{Warning
The Park Assist System is no substitute
for careful and attentive driving. The Park
Assist system does not detect children,
pedestrians, bicyclists, animals, or objects
located below the bumper or that are too
close or too far from the vehicle. It is not
(Continued)
Warning (Continued)
available at speeds greater than 9 km/h
(6 mph). To prevent injury, death,
or vehicle damage, even with Park Assist,
always check the area around the vehicle
and check all mirrors before moving
forward or backing.
How the System Works
The vehicle may have a Park
Assist amphitheater-like display on the
cluster with bars that represent the
estimated location of a detected object and
the vehicle’s distance from the object. As a
detected object becomes closer, more bars
light up and change color from yellow to
amber to red.
When an object is first detected in the rear,
one beep will be heard from the rear, or the
driver's seat will pulse two times,
if equipped with Safety Alert Seat. When an
object is very close, five beeps will sound
from the front or rear (depending on the
object's location), or the driver's seat will
pulse five times. Beeps for front are higher
pitched than the rear.

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.
Turning the Feature On or Off
To view available settings from the
infotainment screen, touch Settings >
Vehicle > Collision/Detection Systems.
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

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

242 Driving and Operating
> 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 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.

Limitations
Traffic sign memory may not operate
correctly if:
.The area of the windshield, where the
front camera is located, is not clean or is
affected by foreign objects, e.g. stickers,
window tinting, etc.
.Traffic signs are completely or partially
covered, are too low or high or difficult to
discern.
.Traffic signs are incorrectly mounted or
are damaged.
.Traffic signs do not comply with the
approved traffic sign standards.
.The speed limit is displayed by certain
types of electronic speed signs.
.There are adverse environmental
conditions, e.g. heavy rain, snow, direct
sunlight or shadows.
.The headlights are dirty or not correctly
aligned when driving at night.
.The navigation map data is out of date.
.The navigation map is unavailable.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid crashes due
to unintentional lane departures. This
system uses a camera to detect lanemarkings. The LKA system can be ready to
assist at speeds between approximately
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 may 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.
(Continued)
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 unintendedlane 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 stack. If equipped, the indicator light
on the button comes on when LKA is on and
turns off when LKA is disabled. In some
vehicles a long press of over three seconds
is required to turn LKA off.
When on,

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. 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.
