Ford Mustang (2005-2014) Owners Manual: Instrument lighting dimmer

• Move the control up or down to adjust the intensity of the panel lighting.
• Move the control to the full upright position, past detent, to turn on the interior lamps.
• Move the control down, past detent, to turn off the interior lights.

Note: The panel dimmer control works only in nighttime illumination mode. It has no effect in daytime illumination mode. Also, selectable features, such as gauge color and halo color, will not be available in daytime illumination mode.

Note: If the battery is disconnected, discharged, or a new battery is installed, the dimmer switch requires re-calibration. Rotate the dimmer switch from the full dim position to the full dome On position to reset.

This will ensure that your displays are visible under all lighting conditions.
