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 27).
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 34) indicator lamp lights up, or
you will see a corresponding message in the
display (
Ypage 182).
iDepending on the equipment, the bulb fail-
ure indicator can fail for all lamps with the
exception of the turn signal lamps.

Automatic headlamp mode
GWARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
L.
Automatic headlamp mode is only a driving aid.
You are responsible for the vehicle lighting at all
times.
Depending on ambient light, the rain and light
sensor automatically switches on the parking
lamps, low-beam headlamps and the license
plate lamp. This excludes weather-related
impairments to visibility, such as snow, fog or
spray.
If there is fog, snow or spray, turn the light
switch quickly from ÃtoL. You could
otherwise briefly interrupt operation of the
headlamps.
XTo switch on automatic headlamp mode:
turn the light switch to Ã.
Key in position 1in the ignition lock: the park-
ing lamps switch on or off automatically
depending on the ambient light.
When the engine is running: if you activate the
"daytime running lamps" function using the
on-board computer, the daytime running
lamps are switched on. The parking lamps and
low-beam headlamps also switch on or off
automatically, depending on the ambient
light.
When the low-beam headlamps are switched
on, the Lindicator lamp in the instrument
cluster lights up.
Fog lamps/rear fog lamp
GWARNING
If you suspect that driving conditions will be
foggy, turn the light switch to Lbefore you
start your journey. Your vehicle may other-
wise not be visible and you could endanger
yourself and others.
GWARNING
In low ambient lighting or foggy conditions,
only switch from position ÃtoL with
the vehicle at a standstill in a safe location.
Switching from ÃtoL will briefly
switch off the headlamps. Doing so while driv-
ing in low ambient lighting conditions may
result in an accident.

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 168).
XTurn the light switch to the Ãposition.
XPress the combination switch beyond the
pressure point in the direction of arrow :
(
Ypage 82).
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
are recognized or the roads are adequately 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 85) 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.
