(I] Tips
The illumination for the instrument cluster lights up whenever you
switch on the ignition with the vehicle headlights off . As the daylight
fades, the instrument cluster illumination likewise dims automati­
cally and will go out completely when the outside light is very low.
This feature is meant to remind you to switch on the headlights when
outside light conditions become poor. •
Appli es to veh icles : wi th xenon headlights
Xenon headlights
After starting the engine , the xenon headlights are automatically
adjusted to the load and angle of the vehicle (for example, during
acceleration and braking). This prevents oncoming traffic from expe­
riencing unnecessary headlight glare from your xenon headlights .
If the system is not operating properly, a warning symbol in the Auto­
Check Control is displayed~

when driving
The benefit of adaptive light is that the curve and the edge of the road
are better illuminated ~ fig. 69. Dynamic adaptive light is controlled
automat ically, depending on vehicle speed and steering wheel angle.
When driving around bends, the headlights are controlled according
to steering wheel angle . So that there is no black hole ahead of the
vehicle , the two main beams pivot at different angles. .,.

Deluxe automatic climate control
Applies to vehicles: with deluxe automat ic climate cont ro l
Description
The climate control system can be used to set a comfort­
able temperature inside the vehicle .
The climate control system is a combination of a heating and ventila­
tion system as well a cooling system respons ible for dehumid ifying
and cooling the air inside the vehicle.
Th e automatic climate control system automatically maintains a
temperature once it has been set. The temperature of the air from
the vents, fan speed (air volume) and air distribution are a lso auto­
matically adjusted . The system also takes into account strong
sunlight so that manual adjustment is not necessary . So in almost all
cases, automatic mode offers the best conditions for the comfort of
the occupants at all times of the year=>
page 90.
Please note the following :
The cooling mode lowers the humidity level inside the vehicle. This
prevents fogging up of the windows.
In the case of high outside humidity and temperatures,
condensation
can drip from the air conditioning system evaporator and form a pool
under the veh icle. This is normal and not an indication of leaks!
At low outs ide temperatures, the fan automatically switches to a
higher speed when the coolant reaches a sufficient temperature
except in the defroster position.
When starting with full throttle, the compressor of the automatic
climate control system is temporarily switched off to achieve full
engine power.
T o ensure engine cooling when the engine is under an extreme load,
the compressor is switched off at h igh coolant temperatures.
Pollutant filter
The pollutant filter (particle filter) ensures that impurities in the
outs ide a ir (e.g. dust, pollen) and odors are significantly reduced or
stopped. The air is also filtered in recirculation mode.
Th e pollutant filter e lement must be changed at the intervals speci­
fied in the service plan so that the performance of the automatic
climate control system is not impaired.
If the effect iveness of the filter decreases premat urely due to opera­
tion of the vehicle in areas with significant pollution, the filter
element must be changed between the specified service dates.
Key recognition
The current climate control settings are automatically stored and
assigned to the key being used. The settings assigned to the key are
restored automatically when the vehicle is started. These settings are
different when the power top is open or closed. Each driver can use
his or her preferred settings witho ut having to man ually adjust them
when using their own key.
If another driver changes the settings while using your key, your
prefer red sett ings will be erased.
Energy management
To prevent the battery from be ing discharged and to restore the
balance of energy, components which require large amounts of
energy are temporarily cut back or switched off=>
page 247. Heating
systems in partic ular require a great dea l of energy. If you notice, for
example, that the rear window heater is not heating , the n it has been
temporarily reduced or switched off by
energy management . These
systems are available again as soon as the energy balance has been
restored. .,,_

Warm and cold
In recirculat ion mode, air is drawn from the vehicle interior, filtered
and recirculated. We recommend selecting recirculation mode under
the following conditions:
When driving through a tunnel or in a traffic jam so that exhaust
fumes and odors cannot enter the vehicle interior .
& WARNING
You should not use the recirculation mode for an extended period
since no fresh air is drawn in. With the air-conditioning switched
off, the windows can fog up, which increases the risk of an
accident! •

Economical use of the climate control
system
Economical use of the climate control system helps save
fuel.
When the climate control system is working in cooling mode,
engine performance is reduced and fuel consumption is
affected. To keep the time the climate control system is on as
short as possible, you should do the following :
- To save fuel, turn off cooling mode by pressing the [AC]
button (indicator light goes out).
- In addition, if you open the window while driving, turn off cooling mode by pressing the
[AC] button (indicator light
goes out).
- If the vehicle is extremely hot due to the heat of the sun,
briefly open doors and windows.
For the sake of the environment
When you save fuel, you reduce emissions from the vehicle. •
App lies to veh ic les: with del uxe automatic climate control
Automatic recirculation
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode.
The basic climate control settings can be adjusted in the
radio or
MMI*.
- Select: Function button [CAR]> Climate control switch.
We recommend that you always keep automatic recirculation ON to
prevent polluted outside ai r from entering the vehicle interior.
If the
air quality sensor located in the climate control system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the factory-installed pollutant filter or whether it is
necessary to switch to recirculation . With heavy concentrations of
pollutants, the climate control system is switched automatically to
recirculation mode and the supply of outside air is blocked . As soon
as the concentration of pollutants in the outside air drops, fresh air is
supplied to the vehicle interior again.
In the event tha t the windows fog up during au tomatic recircula tion,
press the[@] button immediately.
Under certain operating conditions, automatic recirculation is
switched off automatically. When outside temperatures are below
about SO
°F ( + 10 °(), automatic recirculation is limited to
30 seconds. When outside temperatures are below about 30
°F (-
1 °(), automatic recirculation is limited to 15 seconds .•
