{Warning
Use Hitch Guidance only to help
back the vehicle to a trailer hitch
or, when traveling above 12 km/h
(8 mph), to briefly check the status
of your trailer. Do not use for any
other purpose, such as making lane
change decisions. Before making a
lane change, always check the
mirrors and glance over your
shoulder. Improper use could result
in serious injury to you or others.
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 sonartechnology. These sensors are
designed to detect certain objects up
to 2.5 m (8 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
available at speeds greater than
9 km/h (6 mph). To prevent injury,
death, or vehicle damage, even with
(Continued)
Warning (Continued)
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 amphitheatre-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 Pedestrian Alert can be set to Off
or Alert. See“Rear Pedestrian
Detection ”in “Collision/Detection
Systems” underVehicle Personalization
0 130. If equipped, alerts can be set to
beeps or seat pulses. See “Alert Type”
in “Collision/Detection Systems” under
Vehicle Personalization 0130.
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 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
farther back when a trailer is attached
to the 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
TheXbutton on the center stack is
used to turn on or off the Front and
Rear Park Assist, and Backing
Warning and Reverse Automatic
Braking (RAB) systems 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.
RCTA can be turned on or off using
the infotainment system. See
“Collision/Detection Systems” under
Vehicle Personalization 0130.
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), Automatic
Emergency Braking (AEB), Front
Pedestrian Braking (FPB) System, and/
or the Night Vision 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
