cation.
i The hazard warning lamps still operate if

The headlamps are cleaned automatically if
the "Wipe with washe rfluid" function is oper-
ated five times (Y page 137) while the lights
are on and the engine is running. When you
switch off the ignition, the automatic head-
lamp cleaning system is reset and counting is
resumed from 0. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit
the prevailing driving and weathe
rconditions.
It offers advanced functions for improved illu-
mination of the road surface, e.g. depending
on the vehicle speed or weather conditions.
The system includes the active light function,
cornering light function, motorway mode and
extended range foglamps. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" using the on-board computer
(Y page 259). 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
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Active: when the lights are switched on.
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:
if you are driving at speeds below
40 km/ha nd switch on the tur nsignal or turn
the steering wheel.
Not active: if you are driving at speeds above
40 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi-
tion. 130

Replacing bulbs
Important safety notes
Xenon bulbs G
DANGER
Xeno nbulbs are unde rhigh voltage. If you
touch the electrical contacts of a xenon bulb,
you could suffe ranelectric shoc kand be seri-
ously or eve nfatally injured. For this reason,
do not remove the cover of xenon bulbs.
Do no tchange the xenon bulbs yourself, but
have them replaced at a qualified workshop.
If your vehicle is equipped with xenon bulbs,
you can recognise 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 lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs G
WARNING
Bulbs and lamps can be very hot. You should
therefore allow them to cool down before you
change them. Otherwise, you could be burned
if you touch them.
Keep bulbs out of the reach of children. Oth-
erwise, they could damage the bulbs, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may break or even explode and
injure you.
Halogen bulbs are pressurised and can
explode when you change them, particularly
if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the bulbs listed (Y
page 135). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly. Overview of bulb replacement

You can replace the following bulbs. The
details for the bulb type can be found in the

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 25). Overview of climate control systems
Important safety notes

WARNING
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 150).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 96). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observe the interval for replacing the filter, which is
specified in the Service Booklet
.As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30minutes to dry
the air-conditioning system. 142

O To reduce the temperature (Y page 147)Information about using
THERMOTRONIC automatic climate
control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automati ccli-
mate control.
R Activate climate control using the Ãand
¿ buttons .The indicator lamps above
the à and¿ buttons light up.
R In automatic mode, you can also use the
ñ button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM level is recommended.
R Set the temperature to 22 †.
R Only use the demisting function briefly until
the windscreen is clear again.
R Only use the air-recirculation mode briefly,
e.g. if there are unpleasant outside odours
or when in a tunnel. The windows could
otherwise mist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the á button goes out.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The resid-
ual heat function can only be activated or
deactivated with the ignition switched off. Operating the climate control system

Points to observe before use G
WARNING
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
The cooling with air dehumidification function
is only available when the engine is running.
