Unwarmed or cooled air will flow out of the air outlet vents according to the setting of control dial ⇒page 86, fig. 107 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 the doors of a vehicle for which the inte-rior 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 213.
•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 operational problem yourself, or if the cooling capacity decreases, switch the cooling system 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 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 distribution. The system also takes into account sunlight which eliminates the need to alter the settings manually. The automatic mode ⇒page 91 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 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. 109.
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards ⇒page 93, fig. 110.
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒fig. 109. 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 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 minutes 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 the air conditioning system is operating which can only be eliminated through considerable effort and expense (replace-ment of compressor).
•The used air streams out through the air removal openings in the luggage compartment.

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 switched off, engine off, the steering can be locked.
- heating glow plugs on, ignition switched on
•You should not switch on any major electrical components during the heating period otherwise the vehicle battery 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 components 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 the ignition lock prevents the starter being engaged when the engine is running 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 might 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.

Starting-off and Driving96
•Let go of the key as soon as the engine starts otherwise there may be damage to the starter.
The engine running noises may louder at first be louder for a short time after starting the cold engine until oil pressure can be built up in the hydraulic valve clearance compensation. This is quite normal and is not an operating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid ⇒page 208.
It is only possible to tow-start vehicles fitted with a manual gearbox. The tow-starting distance must not be more than 50 metres ⇒page 211.
WARNING
•Never run the engine in non ventilated or enclosed areas. The exhaust gases of the engine contain besides the odorless and colourless carbon monoxide a poisonous gas - hazard! Carbon monoxide can cause uncon-sciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the engine is not running. If the starter is immediately operated after switching off the engine, the starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as long as the engine has not yet reached its normal operating temperature - risk of damaging the engine!
•Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away. When driving the engine reaches its operating temperature more rapidly and the pollutant emissions are lower.
Petrol engines
These engines are fitted with a starter system which selects the correct fuel/air mixture for every external air temperature.
•Do not operate accelerator before and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not start right awayand wait for about 30 seconds before repeating the attempt.
•It is possible that the fuse on the electrical fuel pump is defect if the engine still does not start. Check the fuse and replace it if necessary ⇒page 213.
•If the engine does not start, contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period being controlled automatically in line with the coolant temperature and outside temper-ature.
The preglow indicator light comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating period otherwise the vehicle battery will be drained unnecessarily.
•You should start the engine immediately after the glow plug warning light has gone out.
•The glow plug warning light will come on for about one second if the engine is at a normal operating temperature or if the outside temperature is above +5°C. This means that you can start the engine right away.
•Interrupt the attempt at starting after 10 seconds if the engine does not start right awayand wait for about 30 seconds before repeating the attempt.
•It is possible that the fuse on the diesel preglow system is defect if the engine still does not start. Check the fuse and replace it if necessary ⇒page 213.
