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 106.
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.

160Air 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. 129 Button for auto-
matic air recirculation
Activating air recirculation mode
– Press the button
⇒
Fig. 129.
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.

Air 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. 130
to ensure the best possible ventilation.
The blower only works when the sunroof is closed or tilted open at the rear.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
166Driving
The Electronic Stability Control (ESC) contains the electronic differential lock
(EDL) and the traction control system (ASR). The ESC works together with
the ABS. If a fault in the ABS occurs, both warning lamps light up, but if the
ESC fails, only the ESC warning lamp lights up.
The ESC system is started automatically when the engine is started.
The ESC system is always active and cannot be switched off. The ESC switch
only switches the ASR off.
The ASR can be deactivated when wheel spin is desirable.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose surfaces.
● When the vehicle is stuck, to rock it backwards and forwards.
Press the button to switch the ASR back on when you no longer need wheel
spin.
Situations in which the warning lamp lights
●
On switching the ignition on, it lights up for about two seconds to carry
out a function control.
● The warning lamp will start flashing when the vehicle is moving if the
ESC or the ASR is activated.
● It will light up continuously if there is a fault in the ESC.
WARNING
● Do not forget that the electronic stability control ESC cannot defy the
laws of physics. This should be kept in mind, particularly on slippery and
wet roads and when towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ESC should not
encourage you to run any risks.
● Please refer to the corresponding warning notes on ESC in
⇒ page 188, Intelligent technology.
