Introduction

You can use the auxiliary heating and ventilation system to heat the vehicle interior in the winter and to ventilate it

in the summer. The windshield can be cleared of ice, fog, and a thin layer of snow. The auxiliary heating system is

powered by fuel from the vehicle fuel tank and can be operated when the vehicle is stationary and the ignition is

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

Auxiliary heating exhaust system

The exhaust produced by the auxiliary heating system escapes through an exhaust pipe on the vehicle underbody. The

exhaust pipe must never be blocked by snow, mud, or debris.

DANGER

Among other substances, the auxiliary heating system exhaust contains carbon monoxide, an odorless and colorless

poisonous gas. Carbon monoxide can cause loss of consciousness and death.

● Never turn on the auxiliary heating or leave it running when the vehicle is in an unventilated or closed space.

● Never program the auxiliary heater so that it could switch on or run in unventilated or closed spaces.

WARNING

Components of the auxiliary heating exhaust system become very hot. This can cause fires.

● Never park the vehicle in such a way that parts of the exhaust system come into contact with flammable materials

under the vehicle, such as dry grass.

● Before refueling, switch off the auxiliary heater.

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.

Troubleshooting

The cooling mode

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.

If the engine is very hot or if the outside temperature is extremely high, the function of the cooling mode , the

heating and the defrost may be restricted.

—Switch on the fan.

—Check the safeguard on the air conditioning system .

—Change active combination filters .

—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).

215

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.

When outside humidity is high and ambient temperatures are low, condensation can evaporate when the auxiliary

heating is running. If this is the case, water vapor may escape under the vehicle. This does not indicate vehicle

damage.

The auxiliary heater cannot be switched on

When the vehicle is stationary, the auxiliary heater can be switched on a maximum of three consecutive times with

the maximum operating time limit.

If you park on a hill with very little fuel in the fuel tank(slightly over the reserve quantity), the fuel gauge may be

inaccurate and may cause the auxiliary heater function to be limited.

If the auxiliary heater or ventilation runs for a long time, the 12 V vehicle battery will drain.

1. Drive the vehicle long enough to recharge the 12 V vehicle battery.

Noises when the auxiliary heater and ventilation are switched on

The operating noises when the auxiliary heater and ventilation are switched on are normal and not an indication of a

fault.

Steering information

To make it more difficult to steal the vehicle, the steering must always be locked before leaving the vehicle.

Steering

Power steering on an electromechanical steering system adjusts automatically based on the driving speed, the

steering torque, and the steering angle of the wheels. Electromechanical power steering works only when the engine

is running. The steering also works if the start-stop system engages and the engine switches off.

If the power steering system is impaired or malfunctioning, a significantly greater amount of force than normal must

be used to steer.

On vehicles with Driving Mode Selection, power steering handling can be influenced by the selected driving mode.

Electronic steering lock on vehicles with a starter button

On vehicles with a starter button, the steering column is electronically locked:

1. Stop the vehicle.

2. Depending on the vehicle equipment: move the selector lever into the position.

3. Switch the ignition off and then open the driver's door. The steering column will be locked.

If the steering column does not lock, first open the driver's door and then switch the ignition off. As long as the
