Reverse Camera Lines

[tamugrad2013]

So quick question. I've looked in the manual and didn't see anything. The guidance lines on the rear view camera on both sides mean what. Is that the width of the car on the camera? I just would like to know what the side lines mean.

Probably the estimated tracking of the Edge based on current steering position? Referred to as FIXED GUIDELINES in the owner's manual in the PARKING AIDS section:

 

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 two types of
guides to help you see what is behind your vehicle:
1. Fixed guidelines: Show the actual path the vehicle is moving in while
reversing in a straight line, which can be helpful when backing into a
parking space or aligning the vehicle with another object behind the
vehicle.
2. Centerline: Helps align the center of the vehicle with an object (i.e. a
trailer).
Note: If the transmission is in R (Reverse) and the liftgate is ajar, no
rear view camera features are displayed.
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.
Note: The camera may not operate correctly under the following
conditions:
• Nighttime or dark areas if one or both reverse lamps are not
operating.
• The camera’s view is obstructed by mud, water or debris. Clean the
lens with a soft, lint-free cloth and non-abrasive cleaner.
• The rear of the vehicle is hit or damaged, causing the camera to
become misaligned.

 

Note: Fixed guidelines are only available when the transmission is in R
(Reverse).
Note: The centerline is only available if fixed guidelines are on.
A. Rear bumper
B. Fixed guideline: Red zone
C. Fixed guideline: Yellow zone
D. Fixed guideline: Green zone
E. Centerline
The fixed guidelines fade in and out depending on the steering wheel
position.
Always use caution while reversing. Objects in the red zone are closest
to your vehicle and objects in the green zone are further away. Objects
are getting closer to your vehicle as they move from the green zone to
the yellow or red zones. Use the side view mirrors and rear view mirror
to get better coverage on both sides and rear of the vehicle.
Selectable settings for this feature are FIXED and OFF.
