Lights PANEL DIMMER CONTROL Use to adjust the brightness of the instrument panel when exterior lights are on. • Rotate the thumbwheel from left to right to brighten the instrument panel. • Rotate the thumbwheel from right to left to dim the instrument panel. • Rotate fully to the right (past detent) to turn on interior lamps. • Rotate to the left position (past detent) to turn off the interior lamps and to disable the illuminated entry feature. When the control is in the far left position, it acts as a dome lamp defeat/override. 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.

If your vehicle has been in an accident, the alignment of your headlamps should be checked by your authorized dealer. Vertical aim adjustment 1.
