The exterior lamp band has four positions:

sets the exterior lamps in automatic mode. AUTO mode
will turn the exterior lamps on and off depending on

Forward Lighting system. See Adaptive Forward Lighting
System on page 3-31.
To override AUTO mode, turn the control to off.

lamps and then back to AUTO. Automatic mode will also
reset when your vehicle is turned off and then back
on again when the control is left in the AUTO position.
