lated air mode off as soon as the windows begin misting up.
Note
•We recommend that you do not smoke in the vehicle when the recir-
culating air mode is operating since the smoke which is drawn at the evap-
orator from the interior of the vehicle forms deposits in the evaporator of
the air conditioning system. This produces a permanent odour when the
Climatic is operating which can only be eliminated through considerable
effort and expense (replacement of compressor).

Recirculated air mode
In recirculated air mode air is sucked out of the interior of
the vehicle and then fed back into the interior.
Recirculated air mode prevents polluted air outside the vehicle
from getting into the vehicle, for example when driving through a
tunnel or when standing in a traffic jam. Switching recirculated air mode on
– Press switch
⇒page 100, fig. 94 the switch symbol
lights up.
Switching recirculated air mode off
– Press button again, the button symbol
goes out.
Recirculated air mode is switched off automatically if the air distribution
control is in position ⇒ page 100, fig. 94 . You can also switch recir-
culated air mode on again from this setting by repeatedly pressing button .
WARNING
You should not leave recirculated air mode on over a longer period
of time, as “stale” air may result in fatigue in the driver and occu-
pants, divert your attention and al so cause the windows to mist up.
The risk of having an accident increases. Switch recirculated air
mode off as soon as the windows begin misting up.

Open air outlet vents
– Turn the rotary knob into the upper position.
Close air outlet vents
– Turn the rotary knob into the lower position.
Redirecting air flow
– The horizontal as well as the vertical direction of the air flow is
set with the handle in the middle of the air outlet vents.
You can set the air supply to the individual vents with the air distribution
control ⇒page 100, fig. 94 . Air outlet vents 3 and 4 can also be
opened or closed individually:
Unwarmed or cooled air will flow out of the air outlet vents according to the
setting of control dial ⇒page 100, fig. 94 and the atmospheric
conditions.
Using the air conditioni ng system economically
The compressor on the Climatic uses power from the engine when in
cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which
the interior has been strongly heated through the effect of direct sunlight
in order to allow the heated air to escape.
The cooling system should not be switched on while travelling when the
window is open.
The desired interior temperature can also be achieved without switching
in the cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.
Operational problems
If the cooling system does not operate at outside temperatures higher
than +2 °C, there is a problem in the system. The reasons for this may be:
•The fuse of the Climatic is defective. Check the fuse, replace it if
necessary ⇒page 249.
•The cooling system has switched off automatically for a short time
because the coolant temperature of the engine is too hot ⇒page 14.
If you are not able to rectify the operational problem yourself, or if the
cooling capacity decreases, switch the cooling system off. Contact a
specialist garage.

Climatronic (automatic air conditioning)*
Description
The Climatronic system is a combination of an automatic
heating, fresh air and cooling system which provides
optimal comfort for the occupants of the car.
The Climatronic maintains a constant temperature fully automatically,
once it has been set. This is achieved by automatically varying the
temperature of the outflowing air, the blower stages and the air distribu-
tion. The system also takes into account sunlight which eliminates the
need to alter the settings manually. The automatic mode ⇒ page 106
ensures maximum wellbeing of the occupants at all times of the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
•engine running,
•outside temperature above +2 °C,
•the button is not pressed.
If the cooling system is switched on, the temperature and air humidity
drops in the vehicle. The wellbeing of the occupants of the car is enhanced
as a result of this particularly at high outside temperatures and a high air
humidity. The system prevents the windows misting up during the cold
season of the year.
The heating effect is dependent upon the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
It is possible to briefly activate recirculated air mode in order to enhance
the cooling effect ⇒. The air inlet in front of the windscreen must be free of ice, snow or leaves
in order to ensure that the heating and cooling systems operate properly.
The AC compressor is switched off at a high coolant temperature in order
to provide cooling at a high load of the engine.
After switching on the cooling
Condensation from the evaporator of the
air conditioning may drip down and form a puddle below the vehicle. This
is quite normal and not an indication of a leak!
Recommended setting for all periods of the year:
•Set the temperature to 22 °C.
•Press the button ⇒page 105, fig. 96 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly
upwards ⇒page 108, fig. 97 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 105, fig. 96 . The
information in the desired temperature measuring unit appears in the
display.
WARNING
•For your own safety and that of other road users, ensure that all
the windows are free of ice, snow and misting. Please familiarize
yourself about how to correctly operate the heating and ventilation
systems, how to demist and defrost the windows, as well as with
the cooling mode.
•You should not leave recirculated air mode on over a longer
period of time, as “stale” air may result in fatigue in the driver and
occupants, divert your attention and also cause the windows to
mist up. The risk of having an accident increases. Switch recircu-
lated air mode off as soon as the windows begin misting up.

Parking aid*
The parking aid provides a warning of obstacles behind
the vehicle.
The audible parking aid determines the distance between the rear bumper
and an obstacle located behind the vehicle with the aid of ultrasound
sensors. The sensors are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the
obstacle (area ⇒fig. 103 ). The interval between the warning signals
becomes shorter as the clearance is reduced.
A continuous tone sounds from a clearance of just 30 cm (Bereich ) -
danger area. You should not reverse any further after this signal
sounds! Activating
The parking aid is activated automatically when
reverse gear is engaged
and the ignition is turned on. This is confirmed by a brief acknowledge-
ment signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•The parking aid is not a substitute for the driver paying proper
attention and it is always the driver's responsibility to take care
when parking the vehicle or carrying out similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that
there is no small obstacle, such as a rock, thin post, trailer drawbar
etc., behind your vehicle. Such an obstacle might not be within the
range detected by the sensors.
Note
•The parking aid does not operate if you are towing a trailer (applies to
models which feature a factory-fitted towing device*).
•A system fault is indicated if a warning signal sounds for about 5
seconds after switching the ignition on and engaging reverse gear and
there is no obstacle close to your vehicle. Have the fault rectified by a
specialist workshop.
•The sensors must be kept clean and free of ice to enable the parking
aid to operate properly.
•If the parking aid is activated and the selector lever of the automatic
gearbox is in the position , warning signal indicates interruption (vehicle
can no longer move).
