The air flow depends on the driving speed and the fan.
Group of heating regulators
The blower nozzles must always be open. They can be closed for a short time, for example, when smoke enters from outside: for this, both regulators must be placed on all blower nozzles and must be closed. The leaf guard in the engine compartment, the bars on the left and right in front of the windshield must be free of leaves and snow.
With the help of a fan, the intensity of the air flow increases. To improve the microclimate in the cabin, turn on the fan when driving at low speeds.
Nozzles in the middle of the cabin
Comfortable blowing of the upper part of the cabin with cold or slightly warm air is provided in the appropriate position of the temperature controller. Both nozzles are opened with a knurled wheel. In position O, the nozzles are closed.
The air flow increases when the blower is turned on.
The increase in airflow is controlled by switching the fan. The direction of the air flow is controlled by dampers.
Side nozzles
Through them cold or heated air is supplied - depending on the position of the temperature controller. Opens with thumbwheel. In position O, the nozzles are closed. The direction of the air flow is controlled by dampers.
Ventilation
Move the temperature control to the left. Turn on the fan.
For maximum airflow in the upper part of the passenger compartment: set both heating controls to the @@ position, open all nozzles. To blow the lower part of the passenger compartment: set the left control to the @@ position. Air flow to the rear seat. Turn the middle nozzles towards each other and slightly up.
Heating
The heating capacity depends on the coolant temperature and is therefore only set when the engine is hot.
For quick heating of the interior, set the fan to the 3rd stage. A good indoor climate in your car is highly dependent on the correct adjustment of the ventilation and heating systems.
By switching to heating the lower part of the passenger compartment and opening, if necessary, the middle nozzles, it is possible to achieve a temperature difference in the passenger compartment according to the principle "cold head and warm feet".
Heating of the lower part of the cabin
Heating channels are also connected to the rear lower part of the cabin.
Move the temperature control to the right.
Turn on the fan.
Move both air regulators to the left. Close the middle nozzles.
Drying and removing frost from windows
Move all heating system switches to the right.
Turn on the air conditioner.
Close the middle air nozzles.
Turn on the heated rear window.
Side nozzles: If necessary, aim at the side windows to speed up the defrosting.
Heated rear window, heated exterior mirror
Heating functions only when the engine is running.
The switch is located next to the fan switch. Button on the driver's door handle.
