If the combination switch is set toU,
the headlamps may switch off unexpect-

and / or ambient lighting conditions require
you to do so.
In low ambient lighting conditions, only
switch from positionU toõ with the
vehicle at a standstill. Switching fromU
toõ 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

the operation of the vehicle's lights at all
times.iIf the automatic headlamp mode is ac-
tivated, the fog lamps can also be
switched on (

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

low the lamp to cool down before changing
a bulb.
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.
