Surround Vision
If equipped, this feature provides,
additional views to aid in trailering/
towing. The Front Vision Camera
and Surround Vision cameras are
not supported. The system can
show various views in the
infotainment display using cameras
mounted in and around the vehicle
and trailer. The rear camera is in the
tailgate handle and the cargo bed
camera is mounted on the rear of
the cab. Up to two accessory
cameras can be mounted to the rear
and/or interior of the trailer. See
your dealer for these accessory
cameras.
The system 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, when not in R (Reverse),
press the Home or Back button on
the infotainment system or shift into

Troubleshooting
The Transparent Trailer calibration
may take longer than expected or
not calibrate if:
The vehicle is driven too fast
during calibration. Speed should
be maintained below 50 km/h
(31 mph).
The vehicle is not driven straight
during calibration. Steering
should be maintained as straight
as possible, excessive steering
during calibration may extend
calibration time.
Driving and Operating
The calibration is attempted in
low light. Calibration should be
attempted when there is enough
light.
The calibration is attempted
during adverse weather
conditions. Calibration during
conditions such as snow or
heavy rain should be avoided.
The road surface is not ideal for
calibration. Calibration should be
attempted on an alternate road
surface.
The accessory trailer cameras
are swapped at the hitch
connector. Ensure that the
camera mounted to the rear of
the trailer is connected to the
rear trailer camera input.
The accessory trailer camera is
mounted, angled or rotated
outside of the defined mounting
location (see camera installation
instructions).
