Daytime running lights: In vehicles for countries where daytime running
lights are obligatory and in all vehicles with AFS headlights, daytime run-
ning lights are turned on or off with the ignition. Daytime running lights
have main beam flashers, as usual, but not the dipped beam headlight
function
The dipped beam headlights will only work with the ignition on. The head-
lights are automatically switched to side lights after the ignition has been
switched off.
If the side lights or the dipped beam headlights are turned on, the  sym-
bol will come on together with the lights switch.
Note
● If the lights are left on after the key has been taken out of the ignition
lock, a buzzer sounds when the driver door is opened.
● Observe all relevant legal requirements when using the signalling and
lighting systems described here.
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted. 

Automatic headlight switch* (sensor-controlled)
If you set the light switch to “AUTO”, the dipped headlights
will switch on and off automatically according to the ambi-
ent light level.

the dash panel: Light
switch
Turning on dipped beam headlights
– Turn the light switch ⇒ Fig. 84 to the AUTO position.
Turning off dipped beam headlights
– Turn the light switch to position O.
The symbol on the switch lights up when the switch is in the AUTO position.
The dipped beams, side lights, tail lights and number plate lights come on
together when the headlights are switched on automatically.
When you are using the automatic headlights switch, you can also operate
the main beam headlights, however, please note the following: If you ena-
ble the main beam headlights while using the automatic headlights func-
tion during the day (e.g. when driving through a tunnel), but do not disable them again, only the dipped beam headlights will come on the next time
the lights are automatically switched on. To be able to use the main beam
headlights again, you must first pull the main beam lever back to the "off"
position and then push it forward again to "on".
The side lights, headlights, fog lights and rear fog light can still be switched
on manually in the normal way by using lights switch
⇒ page 117.
The interior mirror is fitted with sensors that measure the ambient light. The
dipped beam headlights will be switched on automatically if the available
light drops below the factory preset value (for instance when driving
through a tunnel, etc.). The headlights switch off again automatically when
the light level increases ⇒ 
.
WARNING
● The automatic dipped beam headlights are only intended to assist
the driver. Automatic dipped beam headlights do not relieve the driver of
his or her responsibility to control them and turn off or turn on the lights
manually according to weather or lighting conditions. The light sensors
are, for example, unable to detect rain and fog - you should therefore al-
ways switch on the dipped beam headlights  manually in these condi-
tions and when driving after dark.
● Observe all relevant legal requirements when using the signalling
and lighting systems described here.
Note
● If automatic headlight switching is activated, when the ignition is turned
off the dipped beam headlights are turned off, and when the key is removed
from the ignition the side lights are turned off.
● If you have to attach any type of sticker on the windscreen, do not do so
in front of the sensors. Doing so could prevent the automatic dipped beam
headlight or anti-dazzle function from working correctly or even from work-
ing at all. 

The coming home and leaving home functions are controlled by light sen-
sors in the interior mirror housing. The system will function when the follow-
ing requirements are met:
● The knob is set to position 1.
● The headlights and the ignition are switched off.
● Dark conditions; the sensors register little or no light.
Coming home
When the system is enabled and it is dark, the corresponding exterior lights
switch on as soon as the driver door is opened.
The exterior lights will stay on for up to a maximum of 2 minutes as long as
one of the doors or the rear lid is open.
The exterior lights stay on for about 30 seconds to light up the area around
the vehicle after all the doors and the rear lid have been closed. This time interval is factory-set, but you can have it changed by a special-
ised workshop to suit your own requirements (max. setting is 60 seconds).
Leaving home
The exterior lights are switched on when the vehicle is unlocked with the

button on the remote control key.
The exterior lights go out when the driver door is opened or after 60 sec-
onds when the vehicle locks itself again automatically
⇒ page 108.
WARNING
Before leaving the vehicle, remove the key from the ignition, as the lights
will not go out if the coming home function is activated. This will lead to
battery discharge and vehicle breakdown.
Note
● If you always wish to use the coming home and leaving home functions,
you can leave them permanently switched on. As the system is controlled
via a photosensor, it will only work in dark conditions.
● Permanent use of the coming home and leaving home functions, partic-
ularly on short journeys, will increase the load on the battery. To make sure
the battery is always sufficiently charged, occasionally drive longer distan-
ces.
● If the fog lights have been switched on by the coming home and leaving
home functions, they will always be switched off when you switch on the ig-
nition.
● Observe all relevant legal requirements when using the signalling and
lighting systems described here. 

Air conditioning
Note
If the diode on the ECON button continues to light up when the ECON mode
has been switched off (i.e. the air conditioner has been switched on) this is
due to a defect in one of the air conditioner components. If a malfunction
should occur, please contact a specialised workshop. 
Air recirculation: automatic activation* 
If the outside air is polluted by diesel and petrol emissions,
an air quality sensor in the vehicle will automatically switch
on the air recirculation.
Fig. 140 Button for auto-
matic air recirculation
Activating air recirculation mode
– Press the button 

⇒ 
Fig. 140.
Deactivating air recirculation mode
– Press the 
button again or –
Press the AUTO
button or
– Press button 
.
The automatic air recirculation mode should normally be left switched on at
all times.
The system is ready to operate approx. 30 seconds after the engine ignition
key has been turned. During this initial period, fresh air is fed into the vehi-
cle.
If the air purity sensor in the air conditioner detects a certain concentration
of fumes in the outside air, the control unit will either pass the incoming air
through the pollution filter or automatically switch on the air recirculation. If
there is a high concentration of pollution in the outside air, the air condi-
tioner automatically switches to air recirculation and the supply of air from
the outside is cut off. As soon as the level of pollution decreases, air is fed
into the vehicle from the outside again.
The automatic air recirculation operates for a maximum period of 12 mi-
nutes. If the windows mist up when the automatic air recirculation is on,
press the 
button immediately.
The automatic air recirculation switches itself off under certain circumstan-
ces (for instance if 
or  is selected). In “ECON” and at temperatures
lower than approx. 8°C below zero, the automatic air recirculation mode is
limited to 12 seconds. 

170Air conditioning
Air directed to windows 
This setting directs all the air to outlets 1 and 2. Unlike in setting , the
volume of air delivery remains the same.
Air to the driver/front passenger 
All the air comes from outlets 3 and 4 in the dash panel and from the rear of
the centre console.
Air to the footwells 
Most of the air emerges from outlets 5 and the outlets under the front seats.
Some of the air will also be issued from outlets 3 and 4.
Note
In all of the above air distribution settings, a small amount of air will still
come from the other outlets. 
Economical use of the air conditioner
Economical use of the air conditioner will help save fuel.
Engine power is reduced and fuel consumption increases when the
air conditioner is in cooling mode. To ensure that the system is on-
ly switched on when it is really necessary, please note the follow-
ing points:
– Select ECON mode if you wish to save fuel.
– Select ECON mode if you decide to open the windows or sun-
roof* while driving.
– If the vehicle has heated up after standing in the sun, open the
windows and doors for a short time to cool the vehicle.
For the sake of the environment
By saving fuel you also reduce the amount of pollutants emitted from your
vehicle. 
Key settings
When the ignition is switched on, the air conditioner set-
tings assigned to the key are selected automatically.
The air conditioner settings selected are automatically stored and assigned
to the key in use. When the vehicle is started, the air conditioner automati-
cally selects the settings assigned to the key. Hence, every driver automati-
cally obtains his/her preferred settings without having to select them man-
ually.
Note
Should another driver use the key and enter other settings, the previous
settings will be deleted. 
Solar-powered blower/sunroof*
If the vehicle is parked in sufficiently strong sunlight, the
blower will operate in solar-powered mode when the igni-
tion is switched off.
After the ignition is switched off, the blower is supplied with electrical pow-
er from the sunroof. Please ensure that outlets 3 and 4 are open ⇒ Fig. 141
to ensure the best possible ventilation.
The blower only works when the sunroof is closed or tilted open at the rear. 
