If you hear a warning tone when you leave the
vehicle, the lights may still be switched on.
X Turn the light switch to the Ãposition.
The exterior lighting (except the side lamps/
parking lamps) switches off automatically if
you:
R remove the key from the ignition lock
R open the driver's door with the key in posi-
tion 0in the ignition lock.
Automatic headlamp mode
à is the preferred light switch setting. The
light setting is automatically selected accord- ing to the brightness of the ambient light
(exception: poor visibility due to weather con-
ditions such as fog, snow or spray):
R key in position 1in the ignition lock: the
side lamps are switched on or off automat- ically depending on the brightness of the
ambient light
R With the engine running: depending on the
ambient light conditions, the daytime driv-
ing lights or the parking and dipped-beam
headlamps are switched on or off automat- ically
X To switch on the automatic headlamps:
turn the light switch to the Ãposition. G
WARNING
When the light switch is set to Ã, the
dipped-beam headlamps may not be switched on automatically if there is fog, snow or othercauses 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. The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle
lighting at all times.
The daytime driving lights improve the detect-
ability of your vehicle during the day.
When the side lamps and dipped-beam head-lamps are switched on, the green T(side
lamps) and L(dipped-beam headlamps)
indicator lamps in the instrument cluster light
up.
Dipped-beam headlamps
When the ignition is switched on and the light
switch is in the Lposition, the side lamps
and dipped-beam headlamps are switched on even if the light sensor does not sense dark
ambient light conditions. This is advanta-
geous when there is fog or rain.
X To switch on the dipped-beam head-
lamps: turn the key in the ignition lock to
position 2or start the engine.
X Turn the light switch to the Lposition.
The green Lindicator lamp in the instru-
ment cluster lights up.
Rear foglamp
The rear foglamp improves the visibility of
your vehicle in heavy fog for the following
traffic. Please observe the country-specific
laws on the use of rear foglamps.
X To switch on the rear foglamp: turn the
key in the ignition lock to position 2or start
the engine.
X Turn the light switch to the LorÃ
position.
X Press the Rbutton.
The yellow Rindicator lamp in the
instrument cluster lights up.
X To switch off the rear foglamp: press the
R button.
The yellow Rindicator lamp in the
instrument cluster goes out. Exterior lighting

Side lamps
! If the battery has been excessively dis-
charged, the side lamps or parking lamps
are automatically switched off to enable
the next engine start. Always park your
vehicle safely and sufficiently lit according
to legal standards. Avoid the continuous
use of the Tside lamps for several
hours. If possible, switch on the Xright
or the Wleft parking lamp.
X To switch on: turn the light switch to the
T position.
The green Tindicator lamp in the instru-
ment cluster lights up.
Parking lamps
Switching on the parking lamps ensures that
the corresponding side of the vehicle is illu-
minated.
X To switch on the parking lamps: the key
should not be in the ignition lock or it
should be in position 0.
X Turn the light switch to the W(left-hand
side of the vehicle) or X(right-hand side
of the vehicle) position.

Exterior lightingLights and windscreen wipers
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 remain illuminated while
you are driving. This allows you to recognise
pedestrians, cyclists and animals.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane
in which you are driving and adjusts the light in advance.
Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the direction you are turning, enabling better vis-
ibility in tight bends, for example. It can only
be activated when the dipped-beam head-
lamps are switched on. Active:
R
if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the
steering wheel.
R if you are driving at speeds between
40 km/h and 70 km/h and turn the steer-
ing wheel.
The cornering light function may remain lit for
a short time, but is automatically switched off after no more than three minutes.
Cornering light function with roundaboutfunction:
The cornering light function is activated on
both sides before entering a roundabout
through an evaluation of the current GPS
position of the vehicle. It remains active until
after the vehicle has left the roundabout. In
this way, pedestrians crossing the road, for
example, are illuminated by your vehicle in
good time.
Motorway mode Active:
if you are driving at a speed above
110 km/h and do not make any large steering movements for at least 1,000 mor if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation. 142
Exterior lightingLights and windscreen wipers
Extended range foglamps
The extended range foglamps reduce the
glare experienced by the driver and improve
the illumination of the edge of the carriage-
way.
Active:
if you are driving at speeds below
70 km/h and you switch on the rear foglamp.
Not active: if, following activation, you are
driving at speeds above 100 km/h or if you
switch off the rear foglamp.
Off-road lights The off-road lights facilitate the early recog-
nition of objects/obstacles when driving off-
road thanks to a symmetrical, wider and
brighter distribution of light from the dipped- beam headlamps.
Active: at speeds below 50 km/h.
The off-road lights are only active with the
following off-road programs:
R Slippery
R Off-road
R Travelling uphill
R Rocking free
Not active: at speeds above 50 km/h.
When the off-road lights are switched on, the cornering light function is permanently acti-
vated, the active light function is deactivated
and the headlamp range control is set to
static mode. Adaptive Highbeam Assist Plus
General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam head-
lamps.
Partial main-beam illumination is a form of
illumination whereby the main beam is direc-
ted past other road users. Other road users
are kept out of the main-beam. This prevents glare. If there is a vehicle in front, for example,
the main-beam headlamps illuminate the
areas to its right and left, and the vehicle in
front is illuminated by the dipped-beam head-
lamps.
The system automatically adapts the dipped- beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it
switches on the main-beam headlamps again.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from
traffic signs, the lights are automatically dim-
med and glare for the driver caused by the
reflections is thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. Exterior lighting
