Replacing bulbs
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 
come on, visit an authorized 
Mercedes-Benz Center.Have the LEDs and bulbs for the following 
lamps replaced by an authorized 
Mercedes-Benz Center:
the additional turn signals in the exteri-
or rear view mirrors
the high mounted brake lamp
the brake lamps
the parking lamps and the side marker 
lamps in the tail lamp assemblies
the rear fog lamps
the low beam (Xenon or Bi-Xenon*) 
lamps
the front fog 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 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.
