Get Heating and air conditioning -> Introduction (Auxiliary heater) Guide for Volkswagen Transporter Van Seventh Generation (2021-2025)

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.

Auxiliary heater mode (Climatronic only)

When the auxiliary heater is switched on, the vehicle automatically sets the operating modeHeating or Ventilation

depending on the outside temperature. At high outside temperatures, the auxiliary ventilation system directs fresh

air into the vehicle and prevents the accumulation of heat.

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.

WARNING

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 so that it is switched on and runs 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.
