Limitations

Even if a fairly small section of the screen image appears to be obstructed, this may mean that a relatively large area behind the vehicle is hidden and objects there may not be detected until they are very near the vehicle.
NOTE
Bicycle carriers or other accessories mounted
on the tailgate may obstruct the camera's
field of view.
Keep in mind
• Keep the camera's lens free of dirt, ice and snow. Remove ice and snow carefully to avoid scratching the lens.
• Clean the lens regularly with warm water and a suitable car washing detergent.
