When the System Does Not
Seem To Work Properly
The RVC system may not work
properly or display a clear image if:
The RVC is turned off. See
Turning the Rear Vision Camera
System On or Off earlier in this
section.
It is dark.
The sun or the beam of
headlights is shining directly
into the camera lens.
Ice, snow, mud, or anything else
builds up on the camera lens.
Clean the lens, rinse it with
water, and wipe it with a soft
cloth.
The back of the vehicle is in
an accident, the position and
mounting angle of the camera
can change or the camera can
be affected. Be sure to have the
camera and its position and
mounting angle checked at your
dealer.
The RVC system display in the
rearview mirror may turn off or not
appear as expected due to one
of the following conditions. If this
occurs the left indicator light on the
mirror will flash.
A slow flash may indicate a
loss of video signal, or no video
signal present during the reverse
cycle.
A fast flash may indicate that
the display has been on for
the maximum allowable time
during a reverse cycle, or the
display has reached an over
temperature limit.
Driving and Operating
The fast flash conditions are
used to protect the video
device from high temperature
conditions. Once conditions
return to normal the device will
reset and the green indicator will
stop flashing.
During any of these fault conditions,
the display will be blank and the
indicator will continue to flash as
long as the vehicle is in R (Reverse)
or until the conditions return to
normal.
Pressing and holding
left indicator light is flashing will turn
off the video display along with the
left indicator light.
