{Warning
The camera(s) do not display
children, pedestrians, bicyclists,
crossing traffic, animals, or any
other object outside of the
cameras’field of view, below the
bumper, or under the vehicle.
Shown distances may be different
from actual distances. Do not
drive or park the vehicle using
only these camera(s). Always
check behind and around the
vehicle before driving. Failure to
use proper care may result in
injury, death, or vehicle damage.
Hitch Guidance
This feature displays a single,
centered guideline on the camera
display to assist with aligning a
vehicle’s hitch ball with a trailer
coupler. Select the trailer guidance
line button, then align the trailer
guidance line over the trailer
coupler. Continuously steer the
vehicle to keep the guidance line
centered on the coupler when backing. RVC Park Assist overlays
will not display when the trailer
guidance line is active. Hitch
Guidance is only available in
Standard View.
To check the trailer when in a
forward gear above 12 km/h
(8 mph), touch CAMERA on the
infotainment display to view the rear
camera. Touch X to exit the view or
it will be removed automatically after
eight seconds.
{Warning
Use Hitch Guidance only to help
back the vehicle to a trailer hitch
or, when travelling 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.

at speeds of less than 8 km/h
(5 mph), the sensors on the rear
bumper may detect objects up to
2.5 m (8 ft) behind 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 does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
