Notes on bulb replacement
Only use 12 volt bulbs of the same type 
and with the specified watt rating. 
Switch 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 light 
up, visit an authorized Mercedes-Benz 
Center.
Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized 
Mercedes-Benz Center:
Additional turn signals in the exteri-
or rear view mirrors
High mounted brake lamp
Bi-Xenon* lamps
Front fog lamps
Rear lamps (except license plate 
lamps)
Warning!
G
Bulbs and bulb sockets can be very hot. Al-
low 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
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Bi-Xenon* lamps, 
it is dangerous to replace the bulb or repair 
the lamp and its components. We recom-
mend that you have such work done by a 
qualified technician.
iHave the headlamp adjustment 
checked regularly.
