361 Practical hints
Replacing bulbs
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.
!
Do not replace the LEDs or bulbs yourself.
You could otherwise damage the vehicle lighting
system or parts of the vehicle. Only have the
LEDs or bulbs replaced by an authorized
Mercedes-Benz Center.
i
If the headlamps are fogged up on the inside
as a result of high humidity, driving the vehicle a
distance should clear up the fogging.
i
Substitute bulbs will be brought into use
when lamps malfunction. Observe the messages
in the multifunction display (
page 346).
i
If one of the following bulbs blows, another
bulb will adopt its function:
