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.
XTurn the ignition key to position 2in the igni-
tion lock or start the engine.
XTurn the light switch to LorT.
iIf your vehicle is only equipped with one rear
fog lamp, you must turn the light switch to
L.
