Maximum heat output and the fastest possible defrosting of the windows are possible only when
the engine is running. Do not start your journey until you have good visibility.
To help ensure good visibility, make sure that you use the air conditioning system and the rear
window heating correctly.
Auxiliary heater and ventilation
Introduction
This chapter contains information on the followingsubjects:
Switching the auxiliary heater and ventilation on and off
Programming the auxiliary heater and ventilation
Remote control
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 exhaust system
The emissions generated by the auxiliary heater are discharged via an exhaust pipe underneath the
vehicle. The exhaust pipe must not be blocked by snow, mud or other objects.
WARNING
Among other things, the emissions from the auxiliary heater contain 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 when the vehicle is in unventilated or closed rooms nor let the
auxiliary heater run in unventilated or closed rooms.
Never program the auxiliary heater so that it is switched on and runs in unventilated or closed
rooms.
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.

e date and time set in the vehicle are correct Time
Open the Auxiliary heater menu.
Touch the Set function button.
Select one of the memory locations for a Departure time.
Touch the Activate function button.
Manual air conditioning system: the programmed departure time determines the time at which
the auxiliary heater or ventilation should switch off. The point at which the heating or ventilation
process starts is determined depending on the programmed running time.
Climatronic: on the basis of the programmed departure time, the vehicle automatically
calculates the start time for heating or ventilation to the currently set temperature depending on
the outside temperature.
Press the Running time function button under Adjust in order to select the running time when the
auxiliary heater is switched on using the immediate heat button or remote control.
Checking programming
If a departure time has been activated, the LED in the immediate heat button will light up on the
Climatronic control panel for approximately 10 seconds after the ignition is switched off.
WARNING
Never program the auxiliary heating system so that is switched on and run in unventilated or
enclosed spaces. Among other things, the emissions from the auxiliary heater contain carbon
monoxide, which is an odourless and colourless poisonous gas. Carbon monoxide can cause people
to lose consciousness. It can also cause death.

Deactivating Car-Net services
Fig. 145 Retrofitted sticker in the vehicle if Volkswagen Car-Net services have been permanently
deactivated.
First read and observe the introductoryinformation and safety warnings
If you sell the vehicle or lend it for a longer period, inform the user about the deactivated services
and deactivated control unit.
If your vehicle is already equipped with the legally required emergency call function eCall, this
function will not be affected by the deactivation described here.
Temporary deactivation
If your vehicle is in a workshop, you may find that the service technicians have deactivated individual
or all services for the duration of the workshop visit. The services will be available again once the
work is complete. Please contact your workshop if necessary. Volkswagen Car-Net portfolios can be
deactivated manually in the Infotainment system. The services can then be run again when the
deactivation is cancelled in the Infotainment system. Deactivated services are marked with a
corresponding indication on the start page of the Car-Net portal.
Permanent deactivation
In order to permanently deactivate Car-Net functions in vehicles with the Security & Service or e-
Remote packages, the online connectivity unit must be deactivated by a qualified workshop at your
request.
Once the on-board connectivity unit has been deactivated, the workshop will attach a sticker
Fig. 145to your vehicle (e.g. on the roof console). The sticker shows that neither the Volkswagen
emergency call service nor the automatic accident notification will work. All other e-Remote and
Security & Service services will also be deactivated.
