Before making a lane change,

Surround Vision (270 Degrees

If equipped, the Surround Vision
(270 Degrees) has additional
trailering views and no Front Vision
Camera. It can display various
views surrounding the vehicle in the
infotainment display using three
cameras mounted around the vehicle. The side cameras are on
the bottom of the outside mirrors
and the rear camera is in the
tailgate handle. A fourth camera can
be mounted to the rear of a trailer to
allow access to all possible camera
features. See your dealer for an
accessory fourth trailer camera.
The Surround Vision (270 Degrees)
can be accessed by selecting
CAMERA in the infotainment display
or when the vehicle is shifted into
R (Reverse). To return to the
previous screen sooner, press any
button on the infotainment system, shift into P (Park), or, while in D
(Drive), reach a vehicle speed of
approximately 12 km/h (8 mph).
