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 26). 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
countries. Lamp 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 lightin gputs the operating
safety of the vehicle at risk.
For this reason, check the condition and
function of your vehicle's lighting system and,
if necessary, that of the trailer before each
journey.
The bulb failure indicator monitors all of the
exterio rlighting lamps, except the perimeter
lamp and the trailer lighting. If a bulb fails,
either the 0002(Ypage 34) indicator lamp
lights up, or you will see a corresponding
message in the display (Y page 201).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exceptio nofthe turn signal lamps. Light switch

The headlamp range control is used to adapt
the downward angle of the headlamp beams
in accordance with the loadony our vehicle.
The cone of light from the headlamps changes
if seats are occupied or if the cargo
compartment 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.
X Turn headlamp range control 0005to the
corresponding position. The road ahead
should be lit up for 40 mto 100 mand the
low-bea mheadlamps should not cause
glare to oncoming traffic.
Select position 0011if 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 the
turn signals or turn the steering wheel.
R you are driving at speeds between
25mph (40 km/h) and43 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. Hazard warning lamps
