Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 26).
Exterior lighting
Important safety notes
For reasons of safety, we recommend that you
drive with the lights switched on even during the
daytime. There may be differences in operation
due to legal requirements and voluntary recom-
mendations in some countries.
Bulb failure indicator
The bulb failure indicator is only an aid. You are
responsible for the proper functioning of the
vehicle lighting. Insufficient or non-functioning
vehicle lighting puts the operating safety of the
vehicle at risk.
For this reason, check the condition and func-
tion of your vehicle's lighting system and, if nec-
essary, that of the trailer before each journey.
The bulb failure indicator monitors all of the
exterior lighting lamps, except the perimeter
lamp and the trailer lighting. If a bulb fails, either
the b(
Ypage 33) indicator lamp lights up, or
you will see a corresponding message in the
display (
Ypage 185).
iDepending on the equipment, the bulb fail-
ure indicator can fail for all lamps with the
exception of the turn signal lamps.

Changing bulbs
Important safety notes
GDANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop.
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
!Make sure the bulbs are always securely
installed.
If your vehicle is equipped with Bi-Xenon bulbs,
you can recognize this by the following: the cone
of light from the Xenon bulbs moves from the
top to the bottom and back again when you start
the engine. For this to be observed, the low-
beam headlamps must be switched on before
starting the engine.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make
sure that these function correctly at all times.
Have the headlamp setting checked regularly.
RAlways switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
RDo not touch the glass tube of new bulbs with your bare hands. Always use a clean, lint-free
cloth or only touch the base of the bulb when
installing.
Even minor contamination can burn into the
glass surface and reduce the service life of the
bulbs.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube.
The bulb could explode.
ROnly use bulbs in closed lamps which have
been designed for this purpose.
ROnly use spare bulbs of the same type and
with the prescribed voltage
RProtect the bulbs from moisture when in use.
If the new bulb still does not light up, consult a
qualified specialist workshop.
RHave the LEDs and bulbs of the following
lamps changed at a qualified specialist work-
shop:
-the additional turn signals in the exterior
mirrors
-the high-mounted brake lamp
-LED daytime running lamps (Bi-Xenon
headlamps)
-Bi-Xenon lamps (Bi-Xenon headlamps)
-front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.
