Auxiliary heating (parking heating)
The auxiliary heating (auxiliary heating) functions in connection with the air-con-
ditioning system or Climatronic.
It can be used when stationary, when the engine is switched off to preheat the
vehicle and while driving (e.g. during the heating phase of the engine).
The engine is also preheated, if the auxiliary heating is switched on when the ve-
hicle is stationary and the engine is switched off. This is not valid for vehicles with
the 3.6 l/191 kW
FSI engine.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank. The coolant warms up the air, which (if the blower speed is
not set to zero) flows into the passenger compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun). WARNING
■ The auxiliary heating must never be operated in closed rooms - risk of poi-
soning! ■ The auxiliary heating must not be running during refuelling - risk of fire.
■ The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore, if you wish to operate the auxiliary heating, do not park the
vehicle in such a way that the exhaust gases from the auxiliary heating can
come into contact with highly flammable materials (e.g. dry grass) or easily in-
flammable substances (e.g. spilt fuel). Note
■ If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
The auxiliary heating automatically controls the filling level in the fuel tank. If only
a low quantity of fuel is present in the fuel tank, the function of the auxiliary
heating is blocked. ■ The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
■ If the auxiliary heating and ventilation is running, the vehicle battery discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometres in order to recharge
the vehicle battery.
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.
■ At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
■ After switching off the auxiliary heating, the coolant pump runs for a short peri-
od.
■ The auxiliary heating and ventilation does not switch on or comes on, if the ve-
hicle battery indicates a low loading state » page 186, Automatic load deactiva-
tion .
■ The auxiliary heating (parking heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please re-
fuel! ■ The air inlet in front of the windscreen must be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
■ So that warm air can flow into the vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by
you, leave the fan switched on and leave the air outlet vents in an open position.
It is recommended to put the air flow in the position  or . Ð
100 Using the system

Direct switching on/off
Fig. 110
Button for direct switching on/
off of the auxiliary heating (aux-
iliary heating and ventilation) on
the operating part of the air con-
ditioning system
First read and observe the introductory information and safety warn-
ings on page 100.
The auxiliary heating (auxiliary heating and ventilation) can be
directly switched
on or off at any time using the button  » Fig. 110 on the operating part of the
air-conditioning system, on the operating part of the Climatronic system or via the
radio remote control » page 101.
If the auxiliary heating and ventilation is not switched off earlier, it switches off
automatically after the set operating period, in the menu Running time has ex-
pired. ÐSystem settings
First read and observe the introductory information and safety warn-
ings on page 100.
The following menu items can be selected in the menu
Aux. heating in the infor-
mation display (depending on the equipment fitted in the vehicle):
■ Weekday - Set the current weekday.
■ Time - Set the desired running time in 5
minute increments. The running time
can be 10 to 60 minutes.
■ Mode - Set the desired heating/ventilation mode.
■ Start time 1-3 - In each pre-set time, the day and the time (hour and minute) can
be set for switching on the auxiliary heating and/or ventilation. An empty posi-
tion can be found between Sunday and Monday when selecting the day. If this
empty position is selected, the activation is performed without taking into ac-
count the day.
■ Activate - Enable pre-set mode.
ä
ä ■
Dectivate - Disable pre-set mode.
■ Factory setting - Restore factory setting.
■ Back - Return to main menu.
Only one programmed pre-set time can be active.
The last programmed pre-set time remains active.
After the auxiliary heating activates at the set time, it is necessary to pre-set a
time again.
If the pre-set menu is closed by selecting the menu item Back or if no changes
are made on the display for more than 10

seconds, the set values are stored, but
the pre-set time is not activated.
An indicator light on the button  » Fig. 110 on page 101 is illuminated when the
system is running.
The running system deactivates after expiration of the operating period or can be
deactivated earlier by pressing the button to directly switch on/off the auxiliary
heating  or by using the radio remote control.
Ð Radio remote control

For switching on, press the button
ON » Fig. 111.
› For switching off, press the button
OFF .
The transmitter and the battery are housed in the housing of the remote control.
The receiver is located in the interior of the vehicle. £

The air conditioning system

If the battery is properly charged, the effective range is up to 600
m. To switch
on/off the auxiliary heating, hold the radio remote control vertically with the an-
tenna A

» Fig. 111 facing upwards. The antenna must not be covered with the fin-
gers or the palm of the hand during this process. Obstacles between the radio re-
mote control and the vehicle, bad weather conditions and a weaker battery can
clearly reduce the range.
The auxiliary heating can only be switched on/off safely using the radio remote
control, if the distance between the radio remote control and the vehicle is at
least 2 m.
Warning light in the radio remote control
The indicator light in the radio remote control C
» Fig. 111 indicates after a key-
stroke if the remote control signal was received by the auxiliary heating and if the
battery is adequately charged.
Display indicator light Importance
Lights up green for 2 seconds. The auxiliary heating was switched on.
Lights up red for 2 seconds. The auxiliary heating was switched off.
Slowly flashes green for 2 seconds. The ignition signal was not received.
Quickly flashes green for 2 seconds. The auxiliary heating is blocked, e. g
because the tank is nearly empty or
there is a fault in the auxiliary heating.
Flashes red for 2 seconds. The switch off signal was not received.
Lights up orange for 2 seconds, then
green or red. The battery is weak, however the
switching on or off signal was received.
Lights up orange for 2 seconds, then
flashes green or red. The battery is weak, however the
switching on or off signal was not re-
ceived.
Flashes orange for 5 seconds. The battery is discharged, however the
switching on or off signal was not re-
ceived.CAUTION
The radio remote control comprises electronic components and must therefore be
protected against water, severe impacts and direct sunlight. Ð Changing the battery of the radio remote control
First read and observe the introductory information and safety warn-
ings on page 100.
If the indicator light on the radio remote control indicates a weak or discharged
battery,
C
» Fig. 111 on page 101, it must be replaced. The battery is located under
a cover B
» Fig. 111 on page 101 on the back of the radio remote control.
› Insert a flat, blunt object, such as a coin, into the gap on the battery cover, turn
the cover in the opposite direction of the arrow up to the mark and unlock it.
› Change the battery, replace the battery cover and lock it by moving it in the di-
rection of the arrow. For the sake of the environment
Dispose of the old battery in accordance with environmental regulations. Note
■ Pay attention to the correct polarity when changing the battery.
■ The replacement battery must have the same specification as the original bat-
tery. Ð ä
