The monitor is equipped with adjustable guide lines that  should be set 
correctly at the time of installation. Generally, these guidelines are used to 
help drivers estimate the distance from obstacles when parking. There are 
three lines for reference-Red, Yellow and Green. These three lines are  
displayed on the monitor when car is in reverse. The lines should be adjusted 
so the green line starts approximately 9ft away from the rear of car, the 
yellow line starts approximately 6ft away from the rear of car, and the red 
line starts approximately 3ft away from the rear of car. The lines should also 
be adjusted to be approximately 6 inches wider than the vehicle on each side 
to assist in parking.

Place the vehicle into reverse gear and press the guideline adjustment 
key       in the center of the 4 directional keys on the remote control.  

For the right side press the button again to select (XR).

  To adjust the angle of the guidelines press the rotation keys       below the 
4 position keys to rotate the lines clockwise and counter clockwise.  

When you are finished place the vehicle in Park, the monitor will shut off 
and the positions will be saved in the mirror’s memory.  

NOTE: 

The remote control must be at least 1.5 feet from the mirror when 

using it for adjustments or it may not respond.

Adjusting The Guidelines

Use the up, down, left, and right buttons to adjust the location of the 
selected guideline. 

By placing items behind the vehicle at the measurements shown above you 
will be able to easily and quickly customize the parking lines for this particu-
lar  vehicle.
Once you have either marked the area or place items such as traffic cone 
behind the vehicle make sure the parking brake is engaged and no one is 
behind the vehicle.
