Heating and air conditioning system78
Air at a temperature of about 5°C may flow out of the vents under certain circum- stances when the cooling system is operating. 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.
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.
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!
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
•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 Climatic is operating which can only be eliminated through considerable effort and expense (replacement of compressor).
Using the system
Setting temperature
– Turn the control dial ⇒fig. 84 to the right in order to increase the
temperature.
– Turn the control dial to the left in order to increase the tempera-
ture.

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.

The physical principle of a frontal collision
The physical principle of a frontal accident can be explained quite simply:
Motion energy, so-called kinetic energy, is produced as soon as the vehicle is moving, both for the vehicle and its occupants. The magnitude of this kinetic energy depends essentially on the speed at which the vehicle is travelling and on the weight of the vehicle and the occupants. The greater the speed and weight increase,
the greater the amount of energy which has to be absorbed in the event of an acci- dent.
The speed of the vehicle is, nevertheless, the most important factor. Doubling the speed of the vehicle from 25 km/h up to 50 km/hour increases the kinetic energy four times.
The common opinion that it is possible to support your body in a minor accident with your hands, is incorrect. Even in a collision at only a low speed, the forces acting on the body are such that it is no longer possible to support your body.
Even if you only drive at a speed within the range from 30 km/hour to 50 km/hour, the forces which are produced on your body in the event of an accident can easily exceed 10.000 N (Newton). This equals a weight of one tonne (1 000 kg).
In the event of a frontal collision, occupants of the car not wearing a seat belt, are thrown forward and strike in an uncontrolle d way parts of the interior of the car, such as steering wheel, dash panel, windscreen, ⇒fig. 108. The occupants of a vehicle who have not fastened their seat belts may even be thrown out of the vehicle. This can resu lt in fatal injuries.
It is also important that rear seat occupants fasten their seat belts as they will other- wise be thrown through the vehicle in an uncontrolled manner in the event of an accident A rear seat passenger who has not fastened the seat belt is a danger not only to himself but also fo r those seated at the front ⇒fig. 109.
Important safety information regarding the use of
seat belts
The correct use of the seat belts considerably reduces the risk of
injury!
WARNING
•The belt webbing must not be jammed in-between at any point or twisted, or chafe against any sharp edges.
•It is important that the belt webbing is properly routed if the seat belts are to offer their maximum protection ⇒page 120, “How are seat belts correctly fa stened?”.

Taking care of your vehicle and cleaning the vehicle162
Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be washed normally in automatic vehicle wash plants without any problem. The actual stress to which the paintwork is subjected, howeve r, depends primarily on the design of the vehicle wash system, the filtering of th e water and the type of washing and care products used. If the paintwork of your vehicle appears mat after being washed or even has scratches, point this out to the operator of the vehicle wash plant. Use a different vehicle wash plant, if necessary.
There are no particular points to note be fore washing your vehicle in such a plant other than the usual precautionary meas ures (closing windows, moving any factory-fitted aerials down flat against the bodywork, etc.).
If you have any particular atta ch e d p a r t s f i t te d t o y o u r c a r - s u ch a s s p o i l e r, ro o f ra ck system, two-way radio aerial - it is best to first of all consult the operator of the car wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after passing through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aeri al tight before washing the vehicle in an automatic vehicle wash sy stem - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as thor- oughly as possible before wa shing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge, washing glove or a washing brush and only slight pressure. Work from the top to the bottom - beginning with the roof. Only place slight pressure on the vehicle paintwork during cleaning Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas.
Rinse off the vehicle well after giving it a wash and dry it off using a chamois leather.
WARNING
•The ignition should always be switched off when you wash your vehicle - risk of accident!
•Protect your hands and arms from sharp-edged metal parts when you are cleaning the underfloor, the inside of the wheel housings or the wheel trims - risk of cuts.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the door and panel joints if you spray your vehicle in winter down with a hose - risk of freezing.
•Do not use any insect sponges, rough kitchen sponges or similar cleaning prod- ucts - risk of damage to the surface of paintwork.
For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this purpose. This ensures that no water which may be cont aminated by oil flows into the sewage system. It is not even permitted to wash your vehicle in certain areas except at such specific washing bays.
Washing with a high-pressure cleaner
When you wash your vehicle with a high-pre ssure cleaner, it is essential to comply with the instructions for use of the cleaning equipment. This applies in particular to the pressure used and to the spraying distance. Maintain a sufficiently large distance to soft materials such as rubber hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters!
