The fixed and active guidelines fade in andout depending on the steering wheelposition. The active guidelines are notshown when the steering wheel positionis straight.
Always use caution while reversing.Objects in the red zone are closest to yourvehicle and objects in the green zone arefarther away. Objects are getting closer toyour vehicle as they move from the greenzone to the yellow or red zones. Use theexterior mirrors and rear view mirror to getbetter coverage on both sides and rear ofyour vehicle.
Manual Zoom
WARNING
When manual zoom is on, the fullarea behind your vehicle may notshow. Be aware of your surroundingswhen using the manual zoom feature.
