Get Heating and air conditioning Guide for Volkswagen Jetta 4 Door Sixth Generation (2011-2018)

Heating and air conditioning

ꢀ Introduction

In this section you’ll find information about:

Manual controls

Heating and ventilation system controls

Operation

Air vents

Air recirculation

Climate control systems

Your vehicle is equipped with either a manual A/C climate control system or a heating and

ventilation system.

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 climate control system 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 for 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 an 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 ꢀꢁꢂ 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 system 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.

Heating and ventilation system controls

Fig. 131 In the center console: Heating system controls.

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

Temperature

The desired interior temperature cannot be lower than the outside air, because the heating and

ventilation system cannot cool or dehumidify the air.

Heating

Maximum heating output and fast defrosting will only be possible after the engine has reached

operating temperature.

Settings for optimum visibility

ꢀ

Switch off the air recirculation, Air recirculation.

ꢀ

Set the fan to the desired speed ⇒ꢀfig. 131 (2).

Turn the temperature knob to the center position (1).

Open all air vents in the instrument panel, Air vents.

Turn the air distribution knob (3) to the desired setting.

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.

ꢀ

Switch off the air recirculation, Air recirculation.

Set the fan to the desired speed.

Turn the temperature knob to the center position.

Open and adjust all air vents in the instrument panel, Air vents.

Turn the air distribution knob to the desired setting.

Push the ꢀꢁꢂbutton to turn on the air conditioner. The indicator light in the button lights up.

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.

Air vents

Fig. 132 In the instrument panel: Air vents.

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

ꢀ

Additional, non-adjustable 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.

Air recirculation

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

There are different types of air recirculation:

Manual A/C: Air recirculation button.

ꢀ

Heating and ventilation system: Air recirculation button.

ꢂ

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

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.
