the headlamps will not be automatically 
switched on under foggy conditions. 
To minimize risk to you and to others, acti-
vate headlamps by turning exterior lamp 
switch to B when driving or when traffic 
and / or ambient lighting conditions require 
you to do so.
In low ambient lighting conditions, only 
switch from position U to B with the

to B will briefly switch off the head-
lamps. Doing so while driving in low ambient 
lighting conditions may result in an acci-
dent.
The automatic headlamp feature is only an 
aid to the driver. The driver is responsible for 
the operation of the vehicle's lights at all 
times.

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.

low the lamp to cool down before changing 
a bulb.

bulb can explode if you
touch or move it when hot
drop the bulb

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.
