When the System Does Not Seem To
Work Properly
The rear vision camera system may not work
properly or display a clear image in the following
situations:
•
In the dark.
•
When the sun or the beam of headlights is
shining directly into the camera lens.
•
If 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.
•
If the back of the vehicle is in an accident, the
position and mounting angle of the camera
may change or the camera may be affected.
Be sure to have the camera and its position
and mounting angle checked at your dealer.
•
Extreme high or low temperatures or extreme
temperature changes can affect the image
displayed.
