Buick 2005 LaCrosse - Manual (Page 127)

Exterior Lamps
The control located to the
left of the cluster on the
instrument panel, operates
the exterior lamps.
P (On/Off): Turn the control to this position to
manually turn the headlamps on and off. This is a
momentary control that will spring back to AUTO
when released.
AUTO (Automatic): Turn the control to this position to
set your headlamps in automatic mode. AUTO mode,
if enabled, will turn the exterior lamps on and off
automatically depending on how much light is available
outside the vehicle.
Due to the momentary switch design, your automatic
lights may be disabled even if the control is in the
AUTO position.

• Turn the headlamp control from AUTO to off
and release the control. It will return back to
the AUTO position by itself.
• Turn the headlamp control from the parking lamp
position to AUTO.
• Turn the headlamp control from the headlamp
position to AUTO.
