Air recirculation

Manual air conditioning (A/C) and Climatronic

Your vehicle is equipped either with a Manual A/C climate control system or with a Climatronic

climate control system.

Climatronic information appears in the Climatronic display and/or on the screen of the factory-installed

Radio system or Radio & Navigation system.

The temperature units (Fahrenheit or Celsius) in the factory installed radio or navigation system

screen can be changed in the Settings menu in the Premium instrument cluster display in

appropriately equipped vehicles.

The dust and pollen filter

The dust and pollen filter with an activated carbon insert reduces the entry of pollutants into the

passenger compartment.

The dust and pollen filter must be replaced at the intervals recommended in ⇒ꢀbooklet Warranty and

Maintenance so that the air conditioner can work properly.

If the effectiveness of the filter decreases prematurely due to operating the vehicle where the outside

air is heavily polluted, the dust and pollen filter should be replaced more frequently than indicated.

WARNING

Poor visibility increases the risk of collisions and other accidents that cause serious

personal injuries.

ꢀ

Always make sure all windows are clear of ice, snow and condensation for good visibility

to the front, sides, and rear.

Maximum heating output and defrosting performance are not possible until the engine has

reached operating temperature. Wait until you have good visibility before driving off.

Always make sure you know how to properly use the heating and ventilation systems as

well as the rear window defroster that you will need for good visibility.

Never use air recirculation for long periods of time. When the air conditioner is off and

ꢀ

recirculation mode is on, condensation can quickly form on the windows and greatly reduce

visibility.

ꢀ

Always switch off recirculation mode when it is not needed.

WARNING

Stale air causes driver fatigue and reduces driver alertness, which can cause accidents,

collisions and serious personal injury.

ꢀ Never switch off the fan for a long period of time and never use air recirculation a long

period of time because no fresh air will enter the passenger compartment.

NOTICE

ꢀ

If you think the air conditioner is not working properly or may be damaged, switch it off to

help prevent more damage. Have the air conditioner checked by an authorized Volkswagen

dealer or authorized Volkswagen Service Facility.

ꢀ

Air conditioner repair requires specialized knowledge and special tools. Volkswagen

recommends that you see an authorized Volkswagen dealer or an authorized Volkswagen

Service Facility.

ꢀ Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation

system can leave residue on the evaporator and on the dust and pollen active carbon filter,

resulting in permanent odors whenever the air conditioner is switched on.

If the air conditioner is switched off, the fresh outside air will not be dehumidified. To help keep

the windows from fogging over, Volkswagen recommends leaving the air conditioner (compressor)

switched on. Press the A/C button. The indicator light in the button must come on.

When it is very hot and humid outside, water condensation can drip from the air conditioner

evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.

Keep the air intake slots in front of the windshield free of ice, snow and leaves in order to

maintain proper functioning of the heating and ventilation systems.

Maximum heating output and defrosting performance are not possible until the engine has

reached operating temperature.

Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle

battery has been replaced may change or delete settings (including time, date, personal convenience

settings and programming). Check the settings and correct as necessary once the vehicle battery has

built up a sufficient charge.

Operation

ꢀPlease first read and note the introductory information and heed the WARNINGS

The air conditioner works only when the ignition is switched on. The cooling system for the passenger

compartment works only when the engine is running and the fan is on.

The air conditioner is most efficient when the windows and the power sunroof are closed. If the vehicle

is stationary and the passenger compartment becomes very hot due to sunlight, briefly opening the

windows and the power sunroof may speed up the cooling process.

Keep the air intake slots in front of the windshield free of ice, snow and leaves so that the heating and

ventilation systems can work properly.

Settings for optimum visibility

When you switch on the cooling system, both the temperature and humidity in the vehicle are reduced.

This will help make passengers feel more comfortable and help keep the windows from fogging up.

System, Main menus: Premium version.

Press and hold the ꢅꢐꢆ and _AUTObuttons to switch the temperature display from Celsius to Fahrenheit

and vice versa.

Heating

Maximum heating output and defrosting performance are not possible until the engine has reached

operating temperature.

Air conditioner does not work

The air conditioner may not switch on for one of the following reasons:

ꢀ

The engine is not running.

The fan is switched off.

The air conditioner fuse has blown.

The outside air temperature is colder than about +38 °F (+3 °C).

The air conditioner compressor has been temporarily switched off due to excessive engine coolant

temperature.

ꢀ There is another malfunction in the vehicle. Have the air conditioner checked by an authorized

Volkswagen dealer or authorized Volkswagen Service Facility.

Special considerations

When it is very hot and humid outside, water condensation can drip from the air conditioner

evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.

The climate control system adjusts the passenger compartment temperature as fast as possible

considering the outside temperature.

Due to residual moisture in the air conditioner, the windshield may fog up after the engine is

started. Switch on the windshield defroster to help evaporate the condensation as quickly as possible.

The air coming out of the vents flows through the passenger compartment and through the vents

under the rear window. Do not cover these slots with clothing or other things.

Air vents

Fig. 171 In the instrument panel: Air vents.

ꢀPlease first read and note the introductory information and heed the WARNINGS

Air vents

To help ensure sufficient heating, cooling and ventilation in the passenger compartment, never close

the air vents completely ⇒ꢀfig. 171 (1).

ꢀ

To open and close the air vents, turn the thumbwheel in the desired direction. When the

thumbwheel is in the ꢑ position, the air vent is closed.

Use the lever on the vent grille to adjust the airflow direction.

ꢀ

Additional air vents are located in the instrument panel (2), in the footwells as well as in the rear area

of the passenger compartment.

NOTICE

Do not place food, medications, or other heat-sensitive things in front of the air vents. Food,

medications, and other things that are sensitive to heat or cold can be damaged or made

unusable by the air flow from the vents.

The air coming out of the vents flows through the passenger compartment and out through vents

below the rear window. Do not cover these slots with clothing or other things.

Air recirculation

ꢀPlease first read and note the introductory information and heed the WARNINGS

General information

There are different types of air recirculation:

Manual air recirculation (manual A/C).

ꢀ

The left indicator light under the button comes on: manual air recirculation

(Climatronic).

ꢀꢅ

The right indicator light under the button comes on: automatic air recirculation

(Climatronic).

The air recirculation mode ꢂ helps prevent outside air from entering the vehicle interior.

In very hot or cold outside temperatures, temporarily switch to manual air recirculation in order to cool

or heat the vehicle interior faster.

For safety reasons, air recirculation is switched off if you push the ꢂ ꢇꢅꢈ button ⇒ꢀ

.

Switching air recirculation on and off manually: manual A/Cꢀ

Switching on: Press the ꢀ button. The indicator light under the button comes on.

Switching off: Press the ꢀ button. The indicator light under the button goes out.

Switching air recirculation on and off manually: Climatronic ^ꢂ

Switching on: Press the ꢂ button repeatedly until the left indicator light under the button comes on.

Switching off: Press the ꢂ button repeatedly until the indicator light under the button goes out.

Automatic air recirculation ^ꢂ

In the _<setting, fresh air enters the passenger compartment. If the system detects an increased

concentration of pollutants in the outside air, it automatically switches to air recirculation. As soon as

the pollutant level is back in the normal range, air recirculation is switched off.

Unpleasant odors cannot be detected by the system.

Air recirculation is not automatically activated under the following outside temperatures and

conditions:

ꢀ

The outside air temperature is colder than about +38 °F (+3 °C).

The cooling system and the windshield wiper are switched off and the outside air temperature is

cooler than about +50 °F (+10 °C).

(+15 °C), and the windshield wiper is switched on.

Switching automatic air recirculation on and off

Switching on: Press the ꢂ button repeatedly until the right indicator light under the button comes on.

Switching off: Press the ꢂ button repeatedly until no indicator light under the button is on.

It is not possible to activate automatic air recirculation when the outside air temperature is colder than

about +38 °F (+3 °C).

Temporarily deactivating automatic air recirculation

ꢀ Press the ꢂ button once to switch to air recirculation temporarily in the event of unpleasant odors.

The left indicator light comes on.

ꢀ Press the ꢂ button again after more than 2 seconds to resume automatic air recirculation. The

right indicator light comes on.

WARNING

Stale air causes driver fatigue and reduces driver alertness, which can cause accidents,

collisions and serious personal injury.

ꢀ

Never use air recirculation mode over an extended period of time, since no fresh air will

enter the passenger compartment.

When the air conditioner is off and recirculation mode is on, condensation can quickly

form on the windows and greatly reduce visibility.

ꢀ

Always switch off recirculation mode when it is not needed.

NOTICE

Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation system

can leave residue on the evaporator and on the dust and pollen active carbon filter, resulting in

permanent odors whenever the air conditioner is switched on.

Climatronic: When backing up and while the automatic wiper/washer is working, air recirculation

is briefly activated to help keep exhaust fumes from getting into the passenger compartment.
