WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel dimmer switch must be calibrated any time the instrument panel dimmer switch is disconnected or the battery is disconnected or discharged. The switch is calibrated by rotating it from the lowest backlighting setting to the DOME LAMP position.
