The headlamp range control is used to adapt
the downward angle of the headlamp beams
in accordance with the load on your vehicle.
The cone of light from the headlamps changes
if seats are occupied or if the cargo compart-
ment is being loaded or unloaded. This can
impair visibility and cause glare to oncoming
traffic.
You can only adjust the headlamp range while
the engine is running. Exterior lighting

glare to oncoming traffic.
Select position 005Aif the vehicle is unladen. Cornering light function (vehicles
with Bi-Xenon headlamps)
The cornering lamps improve the illumination
of the road over a wide angle in the direction
you are turning, enabling better visibility in
tight bends, for example.
The cornering light function switches on
automatically, if:
R you are traveling at a speed of less than
25 mph (40 km/h) and you switch on a turn
signal or turn the steering wheel.
R you are traveling at a speeds of between
25 mph (40 km/h) and 43 mph (70 km/h)
and turn the steering wheel.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than 3 minute s.
i If reverse gear is engaged the lamp on the
opposite side of the vehicle switches on
instead. Hazard warning lamps
G
WARNING
The rear exterior light will be covered if you:
R open the rear doors by 90°
R open the rear dropside.
The vehicle will then be difficult for other road
users to see or will not be seen by them at all,
particularly if it is dark or visibility is poor.
There is a risk of an accident.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant national regulations, by using the warning tri-
angle, for instance. Hazard warning lamp switch
X
To switch on/off: press the002Fhazard
warning lamp switch.
If you have indicated a turn while the hazard
warning lamps are switched on, only the turn
signal lamps on the side of the vehicle
selected will light up.
The hazard warning lamps switch on auto-
matically if:
R an air bag is deployed.
R you brake sharply and bring the vehicle to
a halt from a speed of more than 45 mph
(70 km/h).
If the hazard warning lamps have been
switched on automatically, press the 002F
hazard warning lamp switch to switch them
off.
i The hazard warning lamps work even
when the ignition is switched off. Headlamp cleaning system
The headlamps are cleaned automatically
with a high-pressure water jet if the "Wipe
with washer fluid" function is activated
(Y page 107) while the low-beam headlamps
are on and the engine is running.
Information on checking the washer fluid
level can be found in the "Maintenance and
care" (Y page 257) section. 96

Active light function
The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas will be illuminated to a
greater extent while driving. This allows you
to recognize pedestrians, cyclists and ani-
mals.
Active: when the lights are switched on. Highbeam Assist
General notes You can use this function to set the head-
lamps to change between high beam and low
beam automatically. The system recognizes
vehicles with their lights on, either approach-
ing from the opposite direction or traveling in
front of your vehicle, and consequently
switches the headlamps 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 G
WARNING
Highbeam Assist does not recognize road
users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose 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 sim-
ilar 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 prevail-
ing light, visibility and traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or anything else cover-
ing the sensors

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 99) 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. 100
Changing bulbsLights and windshield wipers
Page 103 of 338

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
- the Bi-Xenon bulbs
- front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop. Front bulbs
