Bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies 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 Center for headlamp ad-
justment.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of
high humidity, driving the vehicle a dis-
tance with the lights on should clear up
the fogging.
iSubstitute bulbs will be brought into
use when the following lamps malfunc-
tion:
Turn signal lamps
Brake lamps
Parking lamps
Tail lamps
Observe the messages in the multi-
function display (
page 345).

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, 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 unit
the rear fog lamps
the low beam (Xenon or Bi-Xenon*)
lamps
the front fog lamps
the front side marker 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.
iHave the headlamp adjustment
checked regularly.
