Adjust each mirror so you can see the side of your
vehicle and the area behind your vehicle. When the
inner switch is in the center position, the mirrors cannot
be adjusted.
Your vehicle may be equipped with the memory
function. These mirror positions, along with the driver's
seat cushion position, can be stored into memory. See
"Memory Seats and Mirrors" in the Index.

improved rear obstacle detection.
To enable this feature, move the power remote mirror
switch to the left (L) or center position. Move the switch
to the right (R) to turn this feature off.
