How Do You Turn on the Dash Board Lights on a Mercedes Benz 500 SEC?


1. Turn the exterior lamp switch clockwise to the 'Parking Lamp' setting or 'Headlight' setting. Both of these settings activate the instrument cluster and dashboard lights. The exterior lamp switch is located to the left of the steering wheel.
2. Rotate the trip odometer knob on the instrument cluster, directly to the left of the speedometer, clockwise to increase the intensity of the instrument cluster and dashboard lights.
3. Rotate the trip odometer knob counterclockwise to decrease the intensity of the instrument cluster and dashboard lights.
