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 possible. Note that your vehicle may not
be equipped with all of the described func-
tions. This also applies to systems and func-
tions relevant to safety.
Read the information on qualified specialist
workshops (Y page 26). Exterior lighting
Important safety notes
G
DANGER
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. G
WARNING
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.
R
Always switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
R Do 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.
R Do not use a bulb that has been dropped or
that has scratches on its glass tube.
The bulb could may explode.
R Only use bulbs in closed lamps which have
been designed for this purpose.
R Only use spare bulbs of the same type and
with the prescribed voltage
R Protect the bulbs from moisture when in
use.
If the new bulb still does not light up, consult
a qualified specialist workshop.
R Have the LEDs and bulbs of the following
lamps changed at a qualified specialist
workshop:
-the additional turn signals in the exterior
mirrors
- the high-mounted brake lamp
- LED daytime running lamps
- the Bi-Xenon bulbs
- front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop. Lamp failure indicator
The bulb failure indicator is only an aid. You
are responsible for the proper functioning of
the vehicle lighting. Insufficient or non-func-
tioning vehicle lighting puts the operating
safety of the vehicle at risk. 92
Exterior lightingLights and windshield wipers
For this reason, check the condition and func-
tion of your vehicle's lighting system and, if
necessary, that of the trailer before each jour-
ney.
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 0049(Ypage 35) indicator lamp
lights up, or you will see a corresponding
message in the display (Y page 210).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exception of the turn signal lamps. Light switch
