Heating, ventilating, cooling

This chapter contains information on the following subjects:

• Controls for the air conditioning system
• Controls for the heating and fresh air system
• Information on the air conditioning system
• Vents
• Air recirculation mode

The dust and pollen filter with activated charcoal reduces the level of impurities in the outside air entering the vehicle.

The dust and pollen filter must be changed regularly to avoid impairing the performance of the air conditioning system.

The dust and pollen filter must be changed more frequently than stated in the service schedule if the efficiency of the filter declines prematurely due to the vehicle being used in areas with high levels of air pollution.

• Exterior views
• Windscreen wiper/washer
• Cleaning and caring for the vehicle exterior

If the cooling system is switched off, the outside air that is drawn into the vehicle is not dehumidified. To prevent the windows misting over, Volkswagen recommends that you leave the air conditioning (compressor) switched on. Press the AC button. The indicator lamp in the button must light up.

Maximum heat output, which is needed to defrost the windows as quickly as possible, is only available when the engine has reached its operating temperature.

Keep the air intake slots in front of the windscreen free of snow, ice and leaves to ensure heating and cooling is not impaired, and to prevent the windows from misting over.

After starting the engine with a discharged vehicle battery or after an emergency start, system settings (time, date, personal convenience settings and programming) may have been changed or deleted. Check and correct the settings as necessary once the vehicle battery has been sufficiently charged.

First read and observe the introductory information and safety warnings .

Press the corresponding button to switch a function on or off. When a function is switched on, an indicator lamp lights up in the button (heating and fresh air system, air conditioning system (manual)), or the activated function is shown in the display field ⇒ fig. 128 4 (Climatronic). Press the button again to switch the function off.

The button for rear window heating is in the upper section of the centre console. The rear window heating only functions when the engine is running and will switch off automatically after approximately 10 minutes.

First read and observe the introductory information and safety warnings .

• Switch off the air recirculation mode.
• Set blower 2 to level 1 or 2.
• Set the temperature selector 1 to the required position.
• Open and position all vents on the dash panel ⇒ Vents.
• Turn the air distribution controller 3 to the desired position.

First read and observe the introductory information and safety warnings .

The cooling system for the vehicle interior only works when the engine is running and the blower is switched on.

The air conditioning system operates most effectively with the windows and the electric panorama sliding and tilting glass roof closed. However, if the vehicle has heated up after standing in the sun for some time, the air inside can be cooled more quickly by opening the windows and the electric panorama sliding and tilting glass roof for a short time.

Switching the cooling system on not only reduces the temperature of the vehicle interior, but also the humidity. This improves comfort for the vehicle occupants and prevents the windows from misting when the outside humidity is high.

Air conditioning system (manual)

• Switch off the air recirculation mode.
• Set the blowers to the required level.
• Open and position all vents on the dash panel ⇒ Vents.
• Turn the air distribution controller to the desired position.
• Press the AC button to switch the cooling system on. The indicator lamp in the button lights up.

Climatronic

• Press the AUTO button.
• Set the temperature to +22°C (+72°F).
• Set the temperature control to the middle position.
• Open and position all vents on the dash panel ⇒ Vents.

Press and hold the AC (or A/C) and AUTO buttons to switch the temperature display from Celsius to Fahrenheit and vice versa.

The following criteria may prevent the cooling system from being switched on:

• The engine is not running.
• The blower is switched off.
• The air conditioning system fuse has blown.
• The ambient temperature is lower than approximately +3℃ (+38°F).
• The compressor has been temporarily switched off because the coolant temperature is too high.
• There is a different fault in the vehicle. The air conditioning system should be checked by a qualified workshop.

If the humidity and temperature outside the vehicle are high, condensation can drip off the evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does not indicate a leak.

The windscreen may mist up after starting the engine due to residual humidity in the air conditioning system. Switch the defrost function on in order to clear the windscreen of condensation or mist as quickly as possible.

First read and observe the introductory information and safety warnings .

The vents ⇒ fig. 130 should be left open to ensure that the vehicle interior is sufficiently heated, ventilated and cooled.

• Turn the relevant thumb wheel (magnified view) in the required direction to open and close the vents. When the mark on the thumb wheel is in position 0, the vent is closed.
• Adjust the direction of the airflow by moving the grille.

Additional vents can be found in the instrument panel 2, in the footwells and in the rear area of the vehicle interior.

Do not cover the ventilation openings underneath the loading edge and in the area above the first-aid kit as this prevents stale air from escaping the vehicle.

First read and observe the introductory information and safety warnings .

The air recirculation mode prevents outside air from entering the vehicle.

If the outside temperature is very high, the air recirculation mode should be selected for a short time in order to cool the vehicle interior more quickly.

For safety reasons, the air recirculation mode will switch off if the MAX button is pressed or if the air distribution regulator is switched to ⇒ .

Switching on: press the button repeatedly until the indicator lamp in the button lights up.

Switching off: press the button repeatedly until the indicator lamp in the button is no longer lit up.

Switching on: press the button repeatedly until the symbol in the display field lights up.

Switching off: press the button repeatedly until the symbol in the display field is no longer lit up.

Climatronic: when reverse gear is selected, air recirculation mode is switched on briefly to prevent exhaust fumes from entering the vehicle interior.
