Get Heating and A/C system Guide for Volkswagen Passat SUV Eight Generation (2014-2023)

Heating and A/C system

Heating, ventilation, and air conditioning

Introduction

The following systems may be installed in your vehicle:

The manual climate control system warms, cools, and removes humidity from the air.

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.

The air conditioner is most effective when the vehicle interior is kept closed. If there is a build-up of heat inside the vehicle, ventilation can help to speed up the

cooling process.

Display of activated functions

Illuminated LEDss on the buttons indicate that the function is activated.

WARNING

Poor visibility through the windows increases the risk of collisions and accidents that can cause serious injury.

Keep all windows free of ice, snow, and fog to have good visibility.

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

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 when it is not necessary.

NOTICE

Food, medication, and objects that are sensitive to heat or cold can become damaged or unusable from the air coming out of the vents.

Do not place any food, medication, or other objects that are sensitive to temperature in front of the vents.

NOTICE

Air recirculation

Please read the introductory information and heed the Warnings and Notice ⇒

and Introduction.

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

Switching air recirculation on and off

1. Press the

button in the climate control bar.

Air recirculation switches off automatically

If one of the following conditions is met, air recirculation switches off automatically ⇒

The defrost function is switched on.

A sensor detects that the vehicle windows could fog up.

WARNING

Lack of air circulation can lead to sudden driver fatigue and lack of concentration, which can cause collisions, accidents, and serious injuries.

Never use recirculation mode for long periods of time, because this prevents fresh air from entering the passenger compartment.

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 when it is not necessary.

NOTICE

Do not smoke in the vehicle when air recirculation is switched on. The smoke can settle on the refrigerant system evaporator and the active combination ﬁlter

and cause permanent odors.

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.

Do not turn on the seat heating function 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

→

The seat is covered with a seat cover

A child restraint is installed on the seat

The seat surface is damp or wet

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

WARNING

Magnetic ﬁelds are generated when the seat heating is operated. In individual cases, these magnetic ﬁelds can have effects on active medical implants (e.g.

pacemakers).

Wearers of an active medical implant should consult their doctor or the manufacturer of their implant before operating the seat heating.

If necessary, make your vehicle occupants aware of this as well.

WARNING

People who cannot feel pain or perceive temperature or can do so only to a limited extent, due to medication, paralysis or chronic illnesses such as diabetes,

could develop burns or hypothermia on the back, buttocks and legs when using seat heating. Such injuries may take a very long time to heal or may never heal

completely. Contact a medical doctor for questions about personal health conditions.

People with a limited perception of pain and/or temperature must never use the seat heating function.

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.

Never sit on the seat while wearing damp or wet clothing.

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

Do not pour any ﬂuids on the seat.

NOTICE

To prevent damage to the seat heating elements, never kneel on the seats or exert pressure on the seating surface and backrest with sharp or pointed

objects.

Fluids, sharp objects, and insulating materials, for example a protective cover or child restraint, can damage the seat heating function.

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

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

Volkswagen Service Facility.

The windows are fogged up

The windows fog up when they are colder than the ambient temperature and the air is very humid. Cold air does not absorb as much moisture as warm air which is

why windows fog up more frequently during cold seasons.

1. Keep the air intake in front of the windshield free of ice, snow, and leaves to improve the heat and cooling output ⇒ 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.
