Heating and air conditioning system82
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.

– Press the button ⇒page 82, fig. 86.
Defrosting windscreen - switching off
– Once again press the butt on or the button .
The temperature control is controlled automatically. More air flows out of the air outlet vents 1 and2.
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 button , the symbol appears on the display.
Switching recirculated air mode off
– Once again press the button or the button , the symbol or
the logo is no longer shown on the display.
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
accident increases. Switch recirculated air mode off as soon as the windows begin misting up.
•After 15 minutes of constant recirculated air mode, the symbol flashes on the display of the Climatronic for 5 minutes. Immediately switch off the recirculated air mode.
Note
If the windscreen mists up, press the button . After the windscreen has been demisted, press the button .
Setting temperature
– You can set the desired interior temperature after switching on the
ignition with the control dial .
You can set the interior temperature between +18°C and +29°C. The interior temperature is regulated automatically within this range. 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.

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.

Starting-off and Driving88
•Let go of the key as soon as the engine starts otherwise there may be damage to the starter.
The engine running noises ma y 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 no rmal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid ⇒page 200.
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 203.
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 i mmediately operated after switching off the engine, the starter or the engine can be damaged.
•Avoid high engine revolutions, full throttl e and high engine loads as long as the engine has not yet reached its normal oper ating temperature - risk of damaging the engine!
•Vehicles which are fitted wi th 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 befo re 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 205.
•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 igniti on 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 th e 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 dies el preglow system is defect if the engine still does not start. Check the fuse and replace it if necessary ⇒page 205.

•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 ⇒page 87, fig. 90 into position .
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 fo r 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 173, “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.

Applying the handbrake
– Pull the handbrake lever up fully.
Releasing the handbrake
– Pull the handbrake lever up slightly and at the same time press in the
locking button ⇒fig. 92.
– Hold the button pressed and push the handbrake lever down fully
⇒ .
The handbrake warning light lights up when the handbrake is applied, provided the ignition is on.
A warning signal sounds and the following text appears in the display* if you have inadvertently driven off with the handbrake applied:
HANDBRAKE ON
The handbrake warning is activated if you drive at a speed of more than 6 km/h for more than 3 seconds.
WARNING
•Please note that the handbrake must be fully released. A handbrake which is only partially released can re sult in the rear brakes overheating which will have a negative effect on the operation of the brake system - risk of accident! In addition this can result in premature wear of the rear brake pads.
•Never leave children unattended in the vehicle. The children might, for example, release the handbrake or take the vehicle out of gear. The vehicle might then move off - risk of accident!
Caution
After the car has come to a stop, always firs t of all apply the handbrake firmly before then additionally engaging a gear (manual gearbox) or moving the selector lever into position P (automatic gearbox).
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 th e aid of ultrasound sensors. The sensors are integrated in the rear bumper.
