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 78, fig. 84 the switch symbol lights up.
Switching recirculated air mode off
– Press button again, the button symbol goes out.
The recirculated air mode is switched off au tomatically if the air distribution control is in position ⇒page 78, fig. 84. You can also switch recirculated 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 occupants, divert your attention and also cause the windows to mist up. The risk of having an acci-dent increases. Switch recirculated air mode off as soon as the windows begin misting up.

You can set the air supply to the individual vents with the air distribution control ⇒ page 78, fig. 84. Air outlet vents 3 and 4 can also be opened or closed individu- ally:
Unwarmed or cooled air will flow out of th e air outlet vents according to the setting of control dial ⇒page 78, fig. 84 and the atmospheric conditions.
Using the air conditioning 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 th e doors of a vehicle for which the inte- rior has been strongly heated through the ef fect 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 205.
•The cooling system has switched off automatically for a short time because the coolant temperature of the engine is too hot ⇒page 10.
If you are not able to rectify the operat ional problem yourself, or if the cooling capacity decreases, switch the cooling sy stem off. Contact a specialist garage.
If there is a fault at the Climatronic, all symbols on the display flash after switching on the ignition for 15 seconds. Contact a specialist garage.
Climatronic (automatic air conditioning)*
Description
The Climatronic system is a comb ination of an automatic heating,
fresh air and cooling system which provides optimal comfort for the
occupants of the car.
The Climatronic maintains a constant temper ature fully automatically, once it has been set. This is achieved by automa tically varying the temperature of the outflowing air, the blower stages and the ai r distribution. The system also takes into account sunlight which eliminates the n eed to alter the settings manually. The automatic mode ⇒page 83 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, th e 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 temperatur es 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 recirc ulated 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 condi- tioning 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 ⇒fig. 86.
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards ⇒ page 85, fig. 87.
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒fig. 86. 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 mistin g. Please familiarize yourself about how to correctly operate th e 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 recirculated air mode off as soon as the windows begin misting up.
Note
•If the cooling system has not been switched on for a lengthy period, odours may be produced at the evaporator because of deposits. Switch the cooling system on at least once a month for approximately 5 mi nutes at the highest blower stage - also during the cold season of the year - in order to remove such odours. Also open a window for a short time.
•We recommend that you do not smoke in the vehicle when the recirculating air mode is operating since the smoke which is drawn at the evaporator from the inte- rior of the vehicle forms deposits in the evaporator of the air conditioning system. This produces a permanent odour when th e air conditioning system is operating which can only be eliminated through co nsiderable effort and expense (replace- ment of compressor).
•The used air streams out through the air removal openings in the luggage compartment.

If you select a tempera-ture of less than +18 °C, “LO” is shown on the display. If you select a temperature above +29 °C, “HI” is shown on the display. In both limit positions the Climatronic operates at maximum cooling or heating capacity, respectively. The temperature is not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg area) and large differences in temperature, for example when getting out of the vehicle, can result in chills in sensitive persons.
Controlling blower
There are a total of seven blower stages available.
The Climatronic system controls the bl ower stages automatically in line
with the interior temperature. You can also, however, adapt the blower
stages manually to suit your particular needs.

place.
WARNING
•You must not adjust the steering wh eel when the vehicle is moving!
•The driver must maintain a distance of at least 25 cm to the steering wheel ⇒fig. 89. Not maintaining this minimum distance will mean that the airbag system will not be able to properly protect you - hazard!
•For s afe ty re a so ns t he le ve r m ust al wa y s b e fi rm ly pus he d up to a voi d the steering wheel alteri ng its position unintentionally when driving - risk of accident!
•If you adjust the steering wheel furthe r towards the head, you will reduce the protection offered by the driver airb ag in the event of an accident. Check that the steering wheel is aligned to the chest.
•When driving, hold the steering wheel with both hands firmly on the outer edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel firmly in the 12 o'clock position or in another way (e.g. in the middle of the steering wheel or at the inner steering wheel edge). In such cases, injuries to the arms, the hands and the head can occur when the driver airbag is deployed.

Ignition lock
Petrol engines
- ignition switched off, engine off, the steering can be locked.
- ignition switched on
- start engine
Diesel engines
- interruption of fuel supply, ignition sw itched off, engine off, the steering can be locked.
- heating glow plugs on, ignition switched on
•You should not switch on any major elec trical components during the heating period otherwise the vehicle batter y will be drained unnecessarily.
- start engine
Applies to all models:
Position
To lock the steering, with the ignition key withdrawn, turn the steering wheel until the steering locking pin is heard to engage. You should always lock the steering as a general rule if you leave your vehicle. This acts as a deterrent against possible theft of your vehicle ⇒.
Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot easily be turned into this position, in order to release the steering lock.
Position
The engine is started in this position. At the same time switched on low beam or main beam or other electrical compon ents with major power consumption are briefly switched off. The ignition key moves back into position when one releases the key.
The ignition key must be turned back into position each time before starting the engine again. The starter repeat lock in th e ignition lock prevents the starter being engaged when the engine is ru nning and thus getting damaged.
WARNING
•When driving, the ignition key must always be in the position (igni- tion switched on) without the engine running. This position is indicated by the warning lights coming on. If this is not the case, it could result in unex- pected locking of the steering wheel - risk of accident!
•Do not withdraw the ignition key from the lock until the car has come to a stop. The steering lock can engage immediately - risk of accident!
•Always withdraw the ignition key if you are going to leave the vehicle, even for a short time. This is particularly important if children are left in the vehicle. The children migh t otherwise start the engine or operate electrical equipment (e.g. power windows) - risk of injury!
Starting the engine
General
You can only start the engine only using an original ignition key.
•Place the gearshift lever into neutral and put on the handbrake firmly before starting the engine.
•The clutch pedal should be fully depressed when starting the engine which means that the starter only has to crank the engine.
