Highbeam Assist
General notes
You can use this function to set the headlamps
to change between low beam and high beam
automatically. The system recognizes vehicles
with their lights on, either approaching from the
opposite direction or traveling in front of your
vehicle, and consequently switches the head-
lamps from high beam to low beam.
Once the system no longer detects any other
vehicles, it reactivates the high-beam head-
lamps.
The system's optical sensor is located behind
the windshield near the overhead control panel.
Important safety notes
GWARNING
Highbeam Assist does not recognize road
users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
In very rare cases, Highbeam Assist may fail to
recognize other road users who have lights, or
may recognize them too late. In this or similar situations, the automatic high-beam head-
lamps will not be deactivated or will be acti-
vated regardless. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Highbeam Assist cannot take into account road,
weather or traffic conditions. Highbeam Assist
is only an aid. You are responsible for adjusting
the vehicle's lighting to the prevailing light, vis-
ibility and traffic conditions.
In particular, the detection of obstacles can be
restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or anything else covering
the sensors
Activating/deactivating Highbeam
Assist
XTo activate: switch on the Highbeam Assist
function using the on-board computer
(
Ypage 170).
XTurn the light switch to the Ãposition.
XPress the combination switch beyond the
pressure point in the direction of arrow :
(
Ypage 84).
Highbeam Assist is active.
The _ or
indicator lamp in the
multifunction display lights up when it is dark
and the light sensor activates the low-beam
headlamps.
If you are driving at speeds above approx-
imately 22 mph (35 km/h) and no other road
users have been detected:
The high-beam headlamps are switched on
automatically. The Kindicator lamp in the
instrument cluster also lights up.
If you are driving at speeds below approx-
imately 19 mph (30 km/h), other road users
have been detected or the roads are ade-
quately lit:
The high-beam headlamps are switched off
automatically. The Kindicator lamp in the
instrument cluster goes out. The _or
indicator lamp in the multifunction
display remains lit.
XTo deactivate: move the combination switch
back to its normal position or move the light
switch to another position.
The _ or
indicator lamp in the
multifunction display goes out.
Headlamps fogged up on the inside
The headlamps may fog up on the inside if there is high atmospheric humidity.
XSwitch on the low-beam headlamps and drive
off.
The level of moisture diminishes, depending
on the length of the journey and the weather
conditions (humidity and temperature).
If the level of moisture does not diminish:
XHave the headlamps checked at a qualified
specialist workshop.

For Cargo Vans and Passenger Vans without
convenience control, the switch for the interior
lighting is on the rear interior light in the cargo
compartment/vehicle interior.
If you move the switch to automatic control, the
rear/cargo compartment lamps go on when you
open a door or unlock the vehicle. They switch
off automatically after 20 minutes, or when you
close the doors.
Motion detector
GWARNING
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:
Rlook directly into the unfiltered laser beam
of the motion detector for an extended
period
Rlook 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 load compartment lighting is also switched
on by the motion detector in the load compart-
ment on panel vans equipped with this feature.
If the motion detector detects a movement in
the cargo compartment when the vehicle is sta-
tionary, 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:
Rthe rear interior light switch (Ypage 87) is set
to automatic control.
Rthe vehicle is stationary, the parking brake is
applied and the brake pedal is not being
depressed
or
Rthe selector lever is in position Pon vehicles
with automatic transmission and the brake
pedal is not being depressed and
Rthe vehicle has not been locked from the out-
side using the key
The motion detector switches off automatically
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
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.
