Park Assist
The vehicle may be equipped
with the Rear Park Assist
(RPA) or Front and Rear Park
Assist (FRPA). The Park Assist
system may provide
assistance to driver when
backing up and parking. Park
Assist uses ultrasonic sensors
in the bumpers to measure the
distance between the vehicle
and objects. The system
calculates the distance
between vehicle and object via
measuring the time it takes for
the ultrasonic waves to
bounce back from the object. Park Assist works only at
speeds up to about 11 Km/h
(7 mph). An illuminated LED in
the parking assist button
indicates that the system is
ready to operate. The sensors
on the bumpers may detect
objects up to 1.8m (6 ft) behind
and 1.25m (4 ft) in front of the
vehicle within a zone 25 cm
(10 in) high off the ground and
below bumper level. These
detection distances may be
shorter during warmer or
humid weather. Blocked
sensors will not detect objects
and can also cause false
detections. Keep the sensors
clean of mud, dirt, snow, ice,
and slush; and clean sensors
after a car wash in freezing
temperatures.
{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
available at speeds greater
than 11 km/h (7 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.

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.
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.
{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 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
Mirror DisplayRight 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. To
view available settings 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

Warning (Continued)
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
Aon 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,
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
A
amber 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
