vehicle lights in each country must be ob-
served.
The driver is personally responsible for the
correct use and adjustment of the lights in all
situations. WARNING
Never drive with just the side lights on, there
is a ri sk
of accident. The side lights are not
bright enough to illuminate the road ahead
and to ensure that other road users are able
to see you. Always use your dipped beam
headlights if it is dark or if visibility is poor. Note
● The dipped beam he a
dlights will only work
with the ignition on. The side lights come on
automatically when the ignition is turned off.
● If the lights are left on after the key has
been taken out of
the ignition lock, an audi-
ble warning sounds while the driver door re-
mains open. This is a reminder to switch the
lights off.
● The rear fog light is so bright that it can
dazzle driv
ers behind you. You should use
the rear fog light only when visibility is very
poor. ●

led with a photosensor.
If the Coming Home or Leaving Home func-
tion is connected, the front side and dipped
lights, the tail lights and the number plate
light will light up to provide assistance.
Coming home function
The Coming Home function is activated by
switching off the ignition and briefly flashing
the lights. When the driver door is opened,
the Coming Home lighting comes on. If the
driver door is already open when the lights
are flashed briefly, the Coming Home lighting
comes on immediately.
When the last door of the vehicle or the rear
lid is closed, the Coming Home function
starts and the switching off the headlights is
delayed.
The Coming Home lighting switches off in the
following cases:
● On completion of the time period establish-
ed for the dela y

driver door opens, no audible warning is
heard, since with the Coming Home function

Cornering lighting using adaptive
he a
dlights. When driving around bends, the headlights
w
i
ll
light the most important areas of the
road.
This cornering light gives better illumination
of the side of the road and the corner area.
The dynamic lighting is controlled automati-
cally according to speed and the steering
wheel angle. The two main headlights move at different
angles
to avoid that the front of the vehicle is
left completely in the dark. Note
The system operates from a speed of about
10 km/h (6 mph). Fog lights with cornering function*
This is an additional light source to dipped
beam hea
dlights
to light up the road as a
bend is taken.
The cornering light operates with the lights
switched on and when driving at less than
40 Km/h (25 mph). Ignition occurs by turning
the steering or connecting the turn signal.

● If the steering wheel is turned to the right,
or the right-hand t urn s

● If the steering wheel is turned to the left, or

Lights and visibility
The instrument lighting (needles) is switched
on when the ignition i s
on and the light i
s
off. The instrument lighting is dimmed auto-
matically as the daylight starts to fade. It
goes out completely when ambient light is
very low. This function is intended to remind
the driver to switch on the dipped beam
headlights in good time when light condi-
tions become poor.
Headlight range control
By using the electrical headlight range con-
trol you can adjust the headlight range to the
load level that is being carried in the vehicle
››› Fig. 135. This way, it is possible to avoid
dazzling oncoming traffic more than necessa-
ry. At the same time, by using the correct
headlight settings, the driver has the best
possible lighting for the road ahead.
The headlights can only be adjusted when
the dipped beam is switched on. Turn the
wheel downwards to lower the headlight
beam from the basic setting 0.
Dynamic headlight range control
Vehicles with gas discharge bulbs (xenon
bulbs) are equipped with dynamic headlight
range control. When you switch on the lights,
their range regulates itself according to the
vehicle load.
Vehicles with gas discharge bulbs do not
have headlight range control. Hazard warning lights
Read the additional information carefully
›››
p
age 22
The hazard warning lights are used to draw
the attention of other road users to your vehi-
cle in emergencies.
If your vehicle breaks down:
1. Park your vehicle at a safe distance from moving tr
affic.
2. Press the button to switch on the hazard warning lights ›
›› .
3. Switch the ignition off.
4. Apply the handbrake.
5. For a manual gearbox, engage 1st gear; for an aut
omatic
gearbox, move the gear
lever to P.
6. Use the warning triangle to draw the atten- tion of other roa
d users to your vehicle.
7. Always take the vehicle key with you when you leav
e the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps
and the turn signal lamp in the switch will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-
nition is switched off. WARNING
● The risk of an ac
cident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic conv
erter can reach, never park in an
area where the catalytic converter could come
into contact with highly inflammable materi-
als, for example dry grass or spilt petrol. This
could start a fire. Note
● The batter y
will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
scribed here i

could otherwise freeze on the windscreen and
obscure your view of the road.

The rain sensor* may not detect enough rain
to swit c

● If necessary, switch on the wipers manually
when water on the wind
screen obstructs visi-
bility. CAUTION
In icy conditions, always check that the wiper
bla de
s are not frozen to the glass before us-
ing the wipers for the first time. If you switch
on the windscreen wipers when the wiper
blades are frozen to the windscreen, you
could damage both the wiper blades and the
wiper motor. Note
● The winds c
reen wipers will only work when
the ignition is switched on.
● The heat output of the heated jets* is con-
troll
ed automatically when the ignition is
switched on, depending upon the outside
temperature.
● In certain versions of vehicles with alarms,
the windsc
reen wiper will only work in inter-
val/rain sensor mode when the ignition is on
and the bonnet closed.
● When the interval wipe function is on, the
interva
ls are directly proportional to the
speed. This way, the higher the vehicle speed
the shorter the intervals. ●
If y ou s
top the vehicle with the windscreen
wiper in position 1 or 2, it will automatically
change to a lower position speed. The set
speed will be resumed when the vehicle pulls
away.
● The windscreen will be wiped again after
approx
imately five seconds once the “auto-
matic wash/wipe system” has been activa-
ted, provided the vehicle is moving (drip func-
tion). If you activate the wipers less than 3
seconds after the drip function, a new wash
sequence will begin without performing the
last wipe. For the “drip” function to work
again, you have to turn the ignition off and
then on again.
● Do not put stickers on the windscreen in
front of the
rain sensor*. This may cause sen-
sor disruption or faults. Rear window wiper
