Practical hints

Replacing bulbs

Safe vehicle operation depends on proper

exterior lighting and signaling. It is there-

fore essential that all bulbs and lamp

assemblies 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 Center for headlamp

adjustment.

Bulbs

If the headlamps or front fog lamps are

fogged up on the inside as a result of

high humidity, driving the vehicle a

distance with the lights on should clear

up the fogging.

Substitute bulbs will be brought into

use when lamps malfunction. Observe

the messages in the multifunction

display (컄 page 323)
