Heating and air conditioning system
Heating
Using the system
The heating system delivers air into the interior of the vehicle and
warms it as required.
Setting temperature
– Turn the control dial ⇒fig. 105 to the right in order to increase the
temperature.
– Turn the control dial to the left in order to increase the tempera-
ture.
Controlling blower
– Turn the blower switch into one of the positions, 1 to 4, in order to
switch the blower on.
– Turn the blower switch into position 0 in order to switch the blower
off.
– Pressing button causes the recirculating air system ⇒ to be
switched on.
Control for air distribution
– You can adjust the direction of the air flow using air distribution regu-
lator ⇒page 85.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to ensure that the heating and ventilation systems operate properly.
All controls apart from the control dial can be set to any desired intermediate position.
The heating effect is dependent upon the coolant temperature, thus full heat output only occurs when the engine has reached its operating temperature.
The blower should aways be on to prevent the windows from misting up.
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.
Note
•If the air distribution is positioned towards the windows, the total amount of air is used to defrost the windows and thus no air will be fed to the footwell. This can lead to restriction of the heating comfort.
•The used air streams out through the air removal openings in the luggage compartment.
•Have the air conditioning system cleaned by a specialist workshop.

Climatic (semi-automatic air conditioning system)*
Description
Climatic is a combined cooling and heating system with electronic
control of the convenience temperature in the vehicle interior. It
makes it possible to optimally control the air temperature at any
season of the year.
Description of the Climatic
It is important for your safety and for your driving comfort that the Climatic is oper-ating properly.
The air conditioning system operates when switch ⇒page 86, fig. 107 is pressed and the following conditions are met:
•engine running,
•outside temperature above +2°C and
•blower switch switched on (positions 1 to 4).
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 controls and can be set to any desired intermediate position.
The blower should aways be on to prevent the windows from misting up.
Note
•The whole heat output will be needed to unfrost the windscreen and side windows. No warm air will be fed to the footwell. This can lead to restriction of the heating comfort.
•The used air streams out through the air removal openings in the luggage compartment.
•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 air conditioning 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.
•Please refer to the information regarding recirculated air mode ⇒page 88.
•Have the air conditioning system cleaned by a specialist workshop.

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.

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.

•Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank has run completely dry - up to one minute. This is because the fuel system must first of all be filled while the attempting to start the engine.
Switching off the engine
– The engine can be switched off by turning the ignition key from posi-
tion into ⇒page 95, fig. 113.
WARNING
•Never switch off the engine before the vehicle is stationary - risk of acci-dent!
•The brake booster only operates when the engine is running. Greater physical effort for braking is required when engine is switched off. Because if you do not stop as normal, this can cause an accident and severe injuries.
Caution
you should not switch the engine off right away at the end of your journey after the engine has been operated for a lengthy period at high loads but should be allowed it to run at idling speed for about 2 minutes. This prevents any accumulation of heat when the engine is switched off.
Note
•The radiator fan may continue running for a further 10 minutes or so after the engine and the ignition have been switched off. The coolant fan may, however, also switch on again after some time if the coolant temperature rises because of an accumulation of heat in the engine or if the engine is warm and the engine compartment is additionally heated by strong sunlight.
•This is why particular care is required when carrying out any work in the engine compartment ⇒page 181, “Working in the engine compartment”.
Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal and hold it fully depressed. Wait a moment before engaging reverse gear in order to avoid any shift noises.
The reversing light will come on once reverse gear is engaged, provided the ignition is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•One should not lay the hand on the shift lever while driving the vehicle. The pressure of the hand will be transferred to the gearshift forks in the gearbox. This can, over a period of time, lead to early wear of the gearshift forks.
•Depress the clutch pedal fully when changing gears, in order to avoid unneces-sary wear and damage.

Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area ⇒page 98, fig. 116). 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 acknowledgement 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
•When operating with a trailer, the parking aid is without function.
•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. It is possible that the audible warning does not function correctly (an obstacle behind the vehicle may not be detected - take extra care). 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).
Cruise control system (CCS)*
Introduction
The cruise control system (CCS) maintains a constant speed, more than 30 km/h, once it has been set, without you having to depress the accelerator pedal. This is only possible within the range which is permitted by the power output and braking power of the engine. The cruise control system makes it possible - particularly on long journeys - for you to rest your “accelerator foot”.
WARNING
•The cruise control system must not, for safety reasons, be used in dense traffic or on unfavourable road surfaces (such as icy roads, slippery roads or loose chippings) - risk of accident!
•In order to prevent unintentional use of the cruise control system, always switch off the system after use.
Note
•Models fitted with a manual gearbox: Always depress the clutch pedal if you switch on the cruise control system when the gearbox is in Neutral. Otherwise the engine can rev up unintentionally.
•The cruise control system is not able to maintain a constant speed when driving on steep downhill sections. The weight of the vehicle increases the speed at which it travels. One should shift down in good time to a lower gear or slow the vehicle down by applying the foot brake.
•It is not possible on vehicles fitted with an automatic gearbox to switch on the cruise control system if the selector lever is in the position P, N or R.
