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 Light Truck Center for 
headlamp adjustment.iIf the headlamps or front fog lamps are 
fogged up on the inside as a result of high humid-
ity, driving the vehicle a distance with the lights 
on should clear up the fogging.iSubstitute bulbs will be brought into use 
when the following lamps malfunction:
Turn signal lamps
Brake lamps
Parking lamps
Tail lamps
Read and observe messages in the multifunction 
display (

Notes on bulb replacement
Only use 12-volt bulbs of the same type 
and with the specified watt rating.
Switch the lights off before changing a 
bulb to prevent short circuits.
Always use a clean lint-free cloth when 
handling bulbs.
Your hands should be dry and free of oil 
and grease.
If the newly installed bulb does not 
come on, contact an authorized 
Mercedes-Benz Light Truck Center.Have the LEDs and bulbs for the following 
lamps replaced by an authorized 
Mercedes-Benz Light Truck Center:
the additional turn signal lamps in the 
exterior rear view mirrors
the high mounted brake lamp
the Bi-Xenon* low beam lamps
the Bi-Xenon* high beam flasher spot-
light
the front side marker lamps
Warning!G
Bulbs and bulb sockets can be very hot. 
Allow the lamp to cool down before chang-
ing 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
scratch 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.!Do not replace the bulbs yourself. You could 
otherwise damage the LEDs or parts of the vehi-
cle. Only have the LEDs replaced by a qualified 
specialist workshop having the necessary skills 
and tools for carrying out the work required.
