Get Heating and air conditioning Guide for Volkswagen Multivan SUV Sixth Generation (2015-2024)

Overview of the Climatronic

Automatic air conditioning system

The Climatronic is an automatic air conditioning system that heats, cools and dehumidifies the air. Automatic mode

enables the Climatronic to control the air temperature, air distribution and air volume automatically.

The air conditioning system will function most effectively if the windows are kept closed. Opening the windows and

glass roof to allow air to enter the vehicle may accelerate cooling if high temperatures have developed in the vehicle

interior.

Some air conditioning system functions depend on the vehicle equipment.

WARNING

Poor visibility through the door windows, windscreen and rear window increases the risk of collisions and accidents

which can cause serious injuries.

● Keep all windows free from ice, snow and condensation.

● Adjust the heating, air conditioning system and rear window heating to prevent the windows from misting up

(→ Heating and air conditioning system).

● Only set off once all windows are clear.

● Use air recirculation mode for a short period only. Condensation could otherwise form on the windows very

quickly so that visibility is greatly reduced.

● Switch off the air recirculation mode when it is no longer required.

Some settings can be stored in the user accounts of the personalisation function and therefore change when

the user account changes .

Introduction

The auxiliary heater and ventilation system can be used to heat the vehicle interior in the winter and ventilate it in

the summer. It is able to clear ice, condensation and a thin layer of snow from the windscreen. The auxiliary heater

is supplied with fuel from the vehicle fuel tank and can be operated when the vehicle is stationary with the ignition

switched off. The auxiliary ventilation system is powered by the 12-volt vehicle battery.

Possible auxiliary heaters

Depending on the equipment in the vehicle, it may have an auxiliary coolant heater, auxiliary air heater or a

combination of both.

—The auxiliary coolant heater primarily heats the front end of the vehicle.

—The auxiliary air heater primarily heats the vehicle interior.

If your vehicle has a auxiliary coolant heater with remote control, the auxiliary heater can also be programmed via an

app on your mobile telephone . Information about the app, the requirements for use and availability, and about

compatible end devices is available on the internet .

Operating mode of the auxiliary heater

You will be able to select different modes depending on the type of auxiliary heater installed in the vehicle. If you are

unable to select a particular mode, the vehicle is not equipped with the relevant auxiliary heater.

—Vehicle interior and windscreen (auxiliary coolant heater).

—Vehicle interior (interior using auxiliary air heater).

—Ventilate (ventilate the vehicle interior). The vehicle interior is not cooled in ventilation mode.

Depending on the equipment in the vehicle, you can select the temperature and the areas to be heated in some

modes.

Auxiliary heater exhaust system

The emissions generated by the auxiliary heater are removed via an exhaust pipe fitted underneath the vehicle. The

exhaust pipe must not be blocked by snow, mud or any objects.

DANGER

Among the emissions from the auxiliary heater is carbon monoxide, which is an odourless and colourless poisonous

gas. Carbon monoxide can cause people to lose consciousness. It can also cause death.

● Never switch on the auxiliary heater or leave the auxiliary heater running if the vehicle is located in enclosed or

unventilated spaces.

● Never program the auxiliary heater to switch on and run in unventilated or enclosed spaces.

WARNING

Parts of the auxiliary heater exhaust system become very hot. This can cause fires.

● Park the vehicle so that no part of the exhaust system can come into contact with any inflammable material

underneath the vehicle, e.g. dry grass.

NOTICE

Heat-sensitive food, medicine and other items could be either damaged or rendered useless.

● Never leave food, medicines or other temperature-sensitive objects in front of the vents.

is switched off when the engine is very hot.

The heating and defrost function are more effective when the engine is warm.

—Switch on the blower.

—Check the fuse of the air conditioning system .

—Replace the enhanced air filter with activated carbon .

—If the fault persists, consult a suitably qualified workshop.

NOTICE

If the air conditioning system is not working, switch it off immediately to prevent consequential damage. Have the

air conditioning system checked by a correspondingly qualified workshop.

Condensation on the windows

Condensation forms on the windows if they are colder than the ambient temperature and the air is very humid. Cold

air can absorb less moisture than warm air, which is why condensation frequently forms on windows in cold weather.

1. Keep the air intake in front of the windscreen free from ice, snow and leaves to improve the heating or cooling

output (→ Vehicle care).

2. To allow air to flow from the front to the rear of the vehicle, leave air vents in the rear of the luggage

compartment clear.

3. Switch on the defrost function (→ Defrost function).

The wrong unit of temperature has been set

1. Change the unit of temperature for all temperature displays in the vehicle using the Infotainment system.

Water or water vapour under the vehicle

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.

If the outside humidity is high and the outside temperature low, condensation may evaporate when the auxiliary

heater is running. If this is the case, steam may appear underneath the vehicle. The vehicle is not damaged.

Auxiliary heater cannot be switched on

When the vehicle is at a standstill, the auxiliary heater can be switched on up to three times in succession for the

maximum operating duration.

If you park on a downhill slope with very little fuel in the tank(just above the reserve level), the fuel gauge may be

inaccurate and lead to functional restrictions of the auxiliary heater.

The 12-volt vehicle battery will be discharged if the auxiliary heater runs several times for an extended period.

1. Drive the vehicle for an appropriate distance in order to recharge the 12-volt vehicle battery.
