Dimmer Automatic Reset Function: Notes
WARNING: This page is about a different car, the 2004 Mitsubishi Eclipse. However, it is still accessible from the selected car via links, so may be relevant.
If the headlight switch is turned off while the high-beam headlights are on, the dimmer switch will be reset. Because of this, the headlights will illuminate at low beam when they are turned on at next opportunity. The dimmer switch will be also reset if the dimmer switch is turned on unintentionally while the passing switch is operated.
