Auxiliary heating (auxiliary heating and ventilation)
Description and important information The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicle with fresh air independent of the
engine.
Auxiliary heating (auxiliary heating)
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
It can be used when stationary, when engine is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).
The engine is also preheated when the vehicle is stationary and the engine is
switched off, if the auxiliary heating is switched on.
The auxiliary heating (auxiliary heating) warms up the coolant during the combus-
tion of fuel from the vehicle tank. The coolant warms up the air, which (if the
blower speed is not set to zero) flows into the occupant 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 do not place the vehicle, if you wish to operate the aux-
iliary heating, in such a way that the exhaust gases of the auxiliary heating
can come easily into contact with inflammable materials (e.g. dry grass) or
easily inflammable substances (e.g. fuel run out). 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 heat-
ing 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 discharg-
es. 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 pe-
riod.
● The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicates a low loading state.
● The auxiliary heating (auxiliary heating) does not switch on, if the following
was shown in the information display or before switching off the ignition: Please
refuel! £ 95

If the system is running, a warning light in the button for direct switching on/off
of the auxiliary heating
 lights up.
The running system deactivates after expiration of the operating period or is de-
activated earlier by pressing the button for direct switching on/off of the auxiliary
heating  ⇒ 
page 96.
A random pre-set time can be deactivated by selecting the menu point Deactivate
in the menu Activate.
After selecting the menu Factory setting in the menu Aux. heating, it is possible
to return to the factory setting. 
Radio remote control The auxiliary heating (auxiliary heating and ventilation) can be
switched on or off with the remote control. Fig. 94 Auxiliary heating: Radio remote control/bottom of the radio remote control with the
battery cover
–
For switching on, press the button ON .
– 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 car.
If the battery is properly charged, the effective range is up to 600

m. For switching
on or off the auxiliary heating, hold the remote control vertically with the antenna A
⇒  fig. 94 towards the top. You must not cover over the antenna with the fin-
gers or the palm of the hand. Obstacles between the radio remote control and the
vehicle, bad weather conditions and a weaker battery can clearly reduce the
range. The auxiliary heating can only be switched on or off with 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 warning light in the radio remote control ⇒ fig. 94 indicates after a keystroke
if the remote control signal was received by the auxiliary heating and if the bat-
tery is adequately charged. Display warning 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
There are electronic components in the radio remote control, protect the remote
control against water, severe shocks and direct sun rays. 
Changing the battery of the radio remote control If the warning light of the radio remote control indicates a weak or discharged
battery,
⇒ fig. 94 , it must be replaced. The battery is located under a cover on the
back of the radio remote control.
– Insert a flat, blunt object, such as a coin, into the gap of the battery cover, turn
it against the direction of the arrow up to the mark, and unlock the cover
⇒ fig. 94 - right.
– Change the battery, replace the battery cover and lock it by moving it in the
direction of the arrow. £ 97

On some vehicles, the battery cover must be removed before removing the fuse
cover ⇒ page 197.
Removing fuse cover
–
Move the circlips A ⇒ 
fig. 178 as far as the stop, the symbol  appears behind
the circlip and remove the cover.
Installing fuse cover
– Position the fuse cover on the fuse box and push the circlips A as far as the
stop - the symbol  is visible behind the circlip.CAUTION
● When unlocking and locking the fuse cover, it must be pressed on the sides to
the box, otherwise damage can occur to the locking mechanism.
● Carefully position the fuse cover in the engine compartment. If the cover was
not correctly positioned, water can get into the fuses and this results in a damage
to the vehicle! 
