Get Auxiliary heater Guide for Volkswagen Caddy SUV Fifth Generation (2020-2025)

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.

Vehicle menu (→ Exit menu).

—OR: Press the button on the remote control (→ Remote control for the auxiliary heater and auxiliary ventilation).

—OR: Program a departure time (→ Auxiliary heater and auxiliary ventilation).

The yellow LED for the auxiliary heater lights up in the instrument cluster when the auxiliary heater is switched on.

The auxiliary heater will not switch on if the 12-volt vehicle battery has a low charge level or the fuel tank is empty.

The auxiliary heater can be switched off as follows:

— Using the immediate heating function in the Auxiliary heater menu in the Infotainment system, or in the Exit

Vehicle menu (→ Exit menu).

— Press the button on the remote control (→ Remote control for the auxiliary heater and auxiliary ventilation).

Auxiliary heater switches off automatically

—When the programmed departure time has been reached or when the set running time has expired (→ Auxiliary

heater and auxiliary ventilation).

—When the yellow indicator lamp(fuel gauge) lights up (→ Fuel gauge).

—If the charge level of the 12-volt vehicle battery is too low.

The auxiliary heater runs on for a short time after it is switched off manually or automatically so that the remaining

fuel in the system can be burnt off.

Operating the auxiliary heater as a supplementary heater

When the engine has been started, the auxiliary heater can continue operation as a supplementary heater. The

following conditions must be met for this:

—The Automatic supplementary heater function is activated in the air conditioning settings in the Infotainment

system.

—The outside temperature is lower than +5°C(+41°F).

The supplementary heating function is switched off automatically after a short time.

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

maximum operating duration.

Operating noises can be heard when the auxiliary heater is switched

on.

The 12-volt vehicle battery will discharge if the auxiliary heater or auxiliary ventilation is run several times

over an extended period. Drive the vehicle for an appropriate distance in order to recharge the 12-volt vehicle

battery.

The fuel gauge may not be accurate(just above the reserve quantity)when the vehicle is parked on a slope;

this may restrict the function of the auxiliary heater.
