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 functions.
This also applies to systems and functions
relevant to safety.
Read the information on qualified specialist
workshops (Y page 25). 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 recommendations in some coun-
tries. 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-func-
tioning 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
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 208).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exception of the turn signal lamps. Light switch

Motion detector
G
WARNING
The motion detector sends the invisible infra- red radiation emitted by LEDs (light emitting
diodes).
These LEDs are classified as class 1M lasers
and can damage the retina if you:
R look directly into the unfiltered laser beam
of the motion detector for an extended
period
R look directly into the laser beam of the
motion detector using optical instruments,
e.g. eyeglasses or a magnifying glass.
There is a risk of injury.
Never look directly into the motion detector.
The cargo compartment lighting is also
switched on by the motion detector in the
cargo compartment of Cargo Vans equipped
with this feature.
If the motion detector detects a movement in the cargo compartment when the vehicle is
stationary, the cargo compartment lighting
switches on for approximately two minutes.
The cargo compartment lighting can be
switched on by the motion detector within
four seconds if:
R the rear interior light switch (Y page 98) is
set to automatic control.
R the vehicle is stationary, the parking brake
is applied and the brake pedal is not being
depressed
Or
R the selector lever is in position Pon vehi-
cles with automatic transmission and the
brake pedal is not being depressed and
R the vehicle has not been locked from the
outside using the key
The motion detector switches off automati-
cally if no change is detected in the vehicle for
several hours, e.g. if a door is opened, if the
ignition key is turned, etc. This prevents the
battery from becoming discharged. Changing bulbs
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. Changing bulbs

R
Do not use a bulb that has been dropped or
that has scratches on its glass tube.
The bulb could 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 (Bi-Xenon
headlamps)
- Bi-Xenon lamps (Bi-Xenon headlamps)
- front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop. Front bulbs
