Bi-Xenon* headlamps
In vehicles with Bi-Xenon* headlamps, the
bulbs of the parking and standing lamps
are LEDs.
!
Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the vehi-
cle. Only have the LEDs replaced by an autho-
rized Mercedes-Benz Center.
Additional turn signal lamp bulbs
The additional turn signal lamps in the
exterior rear view mirrors have LEDs.
If a malfunction occurs or LEDs fail to func-
tion, the entire turn signal unit must be re-
placed. Have the turn signal unit replaced
by an authorized Mercedes-Benz Center.
Front side marker lamp bulbs
Since replacing the side marker lamp bulbs
is a technically highly demanding process,
we recommend you have the side marker
lamp bulbs replaced by an authorized
Mercedes-Benz Center.
