For best results:
Use a long, straight, smooth and level
road when attempting to calibrate.
Drive straight forward.
Drive between 4 mph (6 km/h) and
24 mph (39 km/h).
System Operation
The following warnings or difficulties may
occur during feature operation. Tips to
resolve them are listed below.
The system is not available:
The system relies on many
sub-systems in your vehicle to operate
correctly. If those sub-systems are not
operating correctly the system may not
be available.
Low battery voltage is a condition
which prevents the system from
operating. Please make sure the
battery is correctly charged if the
system is not available.
You may need to drive your vehicle
straight forward above 25 mph
(40 km/h) before the system is
available again.
If the message still displays take your
vehicle to an authorized dealer for
service.
Sticker lost:
If the system cannot initially find the
sticker, it may be necessary for you to
change the lighting conditions by
moving the vehicle and trailer or
waiting until conditions change.
Check for the following if you receive
the lost sticker message while using
the system.
Stop your vehicle as soon as the
message displays.
Make sure the sticker is visible and the
pattern is discernable in the rear view
camera image.
Clean the sticker and camera to make
sure they are unobstructed.
Clean the lens with a soft, lint-free
cloth and water.
Clean the sticker with isopropyl rubbing
alcohol sprayed directly onto the
sticker, and then wipe clean with a soft
cloth.
Remove any items that may be
blocking the view of the sticker.
Depending on your trailer configuration
and any equipment mounted to your
trailer it is possible for the sticker to be
blocked from view of the camera as it
rotates on the hitch ball but not be
blocked during setup. Remove the
obstruction if possible. It is necessary
to remove the sticker from its current
location if the obstruction cannot be
cleared and place a new sticker that is
visible to the camera in all positions of
the trailer behind your vehicle.
Placing the sticker on a surface angled
away from the vehicle reduces
performance. Use a drawbar that
positions the trailer level to the ground
when attached to vehicle. This typically
provides a level surface to mount the
sticker. Place the sticker on a bracket
or other object when no level surface
is available.
Make sure the entire sticker is on a flat
surface that is completely visible to the
camera. Do not fold the sticker over an
edge on the trailer frame. This can
degrade performance.
Shadows on the sticker may effect
tracking performance under some
lighting conditions. Moving the sticker
to another location within the allowed
placement area may improve
performance. Use the change sticker
option in your Towing menu if you
move the sticker.
