Do not put any articles on top of the photocell that is located in the top right corner of the instrument panel. This photocell controls the autolamp. If you cover it, the photocell reacts as if it is nighttime, and the lamps turn on. You can adjust the autolamp to keep the lamps on after you leave your vehicle. The further you move the headlamp knob to the left (counterclockwise), the longer the lamps stay on. You can set the autolamp so the lamps stay on for up to three minutes after you turn your vehicle off. Lighting Up the Interior and Instrument Panel With the parking lamps or headlamps illuminated, you can brighten or dim the lights in the instrument panel. To do this, locate the switch above the headlight control knob and press it up (to brighten the lights) or down (to dim the lights). To turn the interior lights on and off, push the headlamp knob in. The knob controls the light on the instrument panel and the interior light (autolamp feature shown - other models similar) 84
