Exterior Lighting: Headlamps
WARNING: This page is about a different car, the 2009 Mercury Sable, 2009 Ford Taurus X, and 2009 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The headlamp system is a quad-beam pattern system. It consists of replaceable low and high beam bulbs. The headlamp assembly has the park/turn indicator lamp integrated into the headlamp assembly. The SJB supplies voltage to the headlamps when demanded.
If the headlamps are on when the ignition switch is turned off (and the autolamp feature is not selected), the battery saver feature turns off the headlamps after 10 minutes have elapsed.
