왔 Replacing bulbs Bulbs


Safe vehicle operation depends on proper exterior lighting and signaling. It is there- fore essential that all bulbs and lamp as- semblies are in good working order at all times. Correct headlamp adjustment is extremely important. Have headlamps checked and readjusted at regular intervals and when a bulb has been replaced. See an authorized Mercedes-Benz Light Truck Center for headlamp adjustment.


If the headlamps or front fog lamps are fogged up on the inside as a result of high humidity, driving the vehicle a dis- tance with the lights on should clear up the fogging.
