Lighting 61 INSTRUMENT LIGHTING DIMMER Note: If you disconnect the battery or it becomes discharged, the dimmer switch will require re-calibration. Rotate the dimmer switch from the full dim position to the full dome/on position to reset. Note: Move the control to the full upright position, past detent, to turn on the interior lamps. Move the control up or down to adjust the intensity of the panel lighting. DAYTIME RUNNING LAMPS (DRL) (IF EQUIPPED) WARNING: The daytime running lamps system does not activate the tail lamps and may not provide adequate lighting during low visibility driving conditions. Always remember to turn on your headlamps at dusk and in all low visibility conditions, such as daytime fog. Failure to activate your headlamps under these conditions may result in a collision. When you switch the ignition to the on position and the lighting control is in the off or parking lamp position, the daytime running lamps will turn on whenever the headlamps are off. They turn off only when the headlamps are on.
