Heating and air conditioning system

Climatronic

Overview of the Climatronic

Climatronic is an automatic air conditioning system which warms, cools and dehumidiﬁes the air. In automatic mode,

Climatronic can automatically control the air temperature, air distribution and the volume of air.

Certain functions of the air conditioner depend on the vehicle equipment.

Fig. 88 In the upper section of the center console: air conditioning block for the Climatronic system (version 2).

Making Eﬃcient Use of the Air Conditioner

The air conditioner is most effective when the vehicle interior is kept closed. In the event of heat build-up in the vehicle interior

brief ventilation can accelerate the cooling process.

Display of activated functions

Illuminated LEDs in the climate control bar indicate that the function is activated.

In the Air conditioner menu in the Infotainment system, function keys highlighted in color indicate that a function is switched on

⇒ Air conditioner menu in the Infotainment system.

Air conditioner with voice command operation

Some of the air conditioner functions can be operated with voice control, depending on the vehicle equipment ⇒ Voice

control.

WARNING

Icy, snow-covered or foggy door windows restrict visibility very severely. This increases the risk of collisions and

154

accidents, which may result in serious or fatal injuries.

Keep all windows free of ice, snow and fog.

Adjust the heating, air conditioner, and rear window defroster to a setting where the windows do not fog up

⇒ Troubleshooting.

Only start driving when all windows are clear.

Only use recirculation mode for a short time. Otherwise, the windows could fog up very quickly and greatly reduce

visibility.

Always switch off recirculation mode as soon as it is not necessary.

The air is dehumidiﬁed and the blower is set to a higher speed.

The air conditioning system's defrost function clears the windshield of fog and ice.

The air must be dehumidiﬁed when the defrost function is switched on. Therefore when the defrost function is switched on,

you cannot switch air recirculation on or cooling mode off.

Air recirculation

No fresh air will enter the vehicle interior when recirculation mode is switched on ⇒

.

Switch air recirculation on and off in the Air conditioner menu or climate control bar.

When does recirculation mode switch off?

Recirculation mode will switch off in the following situations:

If the defrost function is switched on.

If a sensor detects that the door windows could fog up.

WARNING

A lack of fresh air supply may result in reduced visibility due to fogged up windows and rapid driver fatigue due to stale air.

This can result in collisions, accidents and serious or fatal injuries.

Only use recirculation mode for a short time.

Always switch off recirculation mode as soon as it is not necessary.

NOTICE

Tobacco smoke can settle on the refrigerant system evaporator and the active combination ﬁlter and cause permanent

odors.

To prevent permanent odors, do not smoke in the vehicle when air recirculation is switched on.

Climatronic: When reverse gear is engaged or while the automatic wash and wipe system is on, recirculation mode

switches on automatically so that no odors will enter the vehicle interior.

Manual air conditioning system: At very high outside temperatures, air recirculation helps to briefly cool down the vehicle

interior faster.

Seat heating and seat ventilation

Overview of Seat Heating and Seat Ventilation

The seat heating and seat ventilation function when the engine is running. The front seats and outer rear seats may be heated

in three stages ⇒

. The front seats may also be ventilated from inside in three stages.

The seat ventilation function ventilates the seat using vehicle interior air. This removes moisture from the body. The seat itself

is not cooled directly.

Heating and ventilation levels

The seat heating and seat ventilation are represented by colors. At the highest heating or ventilation level, all three LEDs light

up.

When should the seat heating and seat ventilation be switched off?

Switch off the seat heating and seat ventilation under any of the following conditions:

The seat is occupied by a person with a limited perception of pain or temperature

The seat is not occupied

⇒

.

A child restraint is installed on the seat

Objects are covering the seat cushion, e.g. protective covers, jackets, blankets or bags.

The seat surface is damp or wet

Seat heating only: The interior or exterior temperature is higher than +25 °C (+77 °F).

WARNING

Magnetic ﬁelds are generated when the seat heating is operated. In individual cases, these magnetic ﬁelds can affect

active medical implants (e.g. pacemakers).

If you have a medical implant, you should consult your doctor or the manufacturer of the implant before operating

the seat heating.

Also make your vehicle occupants aware.

WARNING

People who cannot perceive pain or temperature or who have a limited perception of these due to medication, paralysis,

or chronic illnesses such as diabetes could develop burns or undercooling on the back, buttocks, and legs when using

seat heating or seat ventilation. Such injuries could take a very long time to heal or may never heal completely.

If you have a limited perception of pain and/or temperature, never use the seat heating and seat ventilation.

Contact a medical doctor for questions about personal health conditions.

WARNING

If the seat cover is soaked through, this can cause the seat heating to malfunction and increase the risk of burns.

Make sure the seat surface is dry before using the seat heating function.

Do not sit on the seat with wet clothing.

Do not place any wet objects or clothing on the seat.

Do not pour any ﬂuids on the seat.

NOTICE

The heating elements of the seat heating may be damaged by loads concentrated in a single place and insulating

159

materials.

Do not kneel on the seats and do not exert pressure on the seat cushion and backrest with sharp or pointed

objects.

Do not exert pressure on the seat cushion and backrest with pointed objects.

Switch the seat heating off if insulating materials are installed on the seat, e.g. a protective cover or a child

restraint.

Only use the seat heating if the seat is equipped with the original seat covers.

If any odor starts to develop, turn off the seat heating immediately and have it checked by suitably qualiﬁed

professionals. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen

Service Facility.

or heating cannot be switched on or the function is limited

The cooling mode only works when the engine is running and at ambient temperatures above +3 °C (+38 °F).

The heating and defrost function operates better when the engine is warm.

Switch on the fan.

Check the safeguard on the air conditioning system ⇒ Replacing fuses.

Change active combination ﬁlters ⇒ Service.

If the malfunction persists, contact a suitably qualiﬁed professional. Volkswagen recommends contacting an authorized

Volkswagen dealer or authorized Volkswagen Service Facility.

NOTICE

If the air conditioner is not working and is operated further, that can cause subsequent damage.

If the air conditioner is not cooling or warming the air, switch it off immediately.

Have the air conditioner checked by suitably qualiﬁed professionals. Volkswagen recommends contacting an

authorized Volkswagen dealer or authorized Volkswagen Service Facility.

The windows are fogged up

The door windows fog up if they are colder than the ambient temperature and the air is damp. Cold air does not absorb as

much moisture as warm air which is why windows fog up more frequently during cold seasons.

1. To improve the heating and cooling output, keep the air intake in front of the windshield free of ice, snow, and leaves

⇒ Vehicle care.

2. Leave the air duct in the rear section of the luggage compartment uncovered so that air can ﬂow through the vehicle from

front to back.

3. Switch on the defrost function ⇒ Defrost function.

The temperature unit has changed

You can change the unit for all temperature displays in the vehicle using the Infotainment system.

1. Open the Settings menu.

2. Select the Units menu item.

Water or water vapor under the vehicle

In the case of high outside humidity and temperatures, condensation can drip from the air conditioning system evaporator and

pool under the vehicle. This is normal and does not mean there is a leak in the system.
