WARNING: Use caution when turning camera features on or off
while in R (Reverse). Make sure the vehicle is not moving.
Using the Rear View Camera System
The rear view camera system displays what is behind your vehicle when
you place the transmission in R (Reverse). The system uses fixed
guidelines which show the actual path the vehicle is moving in while
reversing in a straight line. This can be helpful when backing into a parking
space or aligning the vehicle with another object behind the vehicle.
Note: Do not use the camera system if the trunk is ajar.
Note: If the image comes on while the transmission is not in R
(Reverse), have the system inspected by your authorized dealer.
Note: When towing, the camera only sees what is being towed behind
the vehicle. This might not provide adequate coverage as it usually
provides in normal operation and some objects might not be seen. In
some vehicles, the guidelines may disappear once the trailer tow
connector is engaged.
