Lights PANEL DIMMER CONTROL Use to adjust the brightness of the instrument panel and all applicable switches in the vehicle during headlamp and parking lamp operation. 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. Move the control to the full downward position, to dim the interior lights to their minimum. The instrument panel/switch lighting remains lit. 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.
