Cornering lamps
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 speed 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 minutes.
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 selec- ted 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.
You can find information on refilling washer
fluid in the "Maintenance and care" section
(Y page 255). Exterior lighting

Highbeam Assist
General notes You can use this function to set the head-
lamps to change between low beam and high 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 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 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

imately 22 mph (35 km/h) and no other
road users have been detected:
The high-beam headlamps are switched on
automatically. The 0057indicator 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 ade-
quately lit:
The high-beam headlamps are switched off automatically. The 0057indicator lamp in
the instrument cluster goes out. The 00CE
or indicator lamp in the multifunc-
tion display remains lit.
X To deactivate: move the combination
switch back to its normal position or move the light switch to another position.
The 00CE or indicator lamp in the
multifunction display goes out. 96

Headlamps fogged up on the inside
The headlamps may fog up on the inside if
there is high atmospheric humidity.
X Switch on the low-beam headlamps and
drive off.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weather conditions (humidity and temper-
ature).
If the level of moisture does not diminish:

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
