NOTE
If water, snow, or mud is stuck on the camera lens, wipe it off using a soft cloth. If it
cannot be wiped off, use a mild detergent.
If the camera temperature changes rapidly (Hot to cold, cold to hot), the rear view
monitor may not operate correctly.
When replacing the tires, consult an Authorized Mazda Dealer. Replacing the tires could
result in deviation of the guide lines which appear on the display.
If the vehicle's front, side, or rear has been involved in a collision, the alignment of
the rear view parking camera (location, installation angle) may have deviated. Always
consult an Authorized Mazda Dealer to have the vehicle inspected.
If "No Video Signal Available" is indicated in the display, there could be a problem with
the camera. Have your vehicle inspected at an Authorized Mazda Dealer.
