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.
iIf 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.
iSubstitute bulbs will be brought into 
use when lamps malfunction. Observe 
the messages in the multifunction 
display (
page 377).

Bulbs and bulb sockets can be very hot. 
Allow the lamp to cool down before 
changing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. 
A bulb can explode if you
touch or move it when hot
drop the bulb

Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is 
dangerous to replace the bulb or repair the 
lamp and its components. We recommend 
that you have such work done by a qualified 
technician.
