perature of the outflowing air, the blower stage and air distribution.
The system also takes sunlight into account, which eliminates the need to alterthe settings manually.
The cooling system only operates if the following conditions are met. The cooling system is switched on » page 112, Control elements .
The engine is running.
The outside temperature above approx. +2 °C.
The cooling system is switched off at a high coolant temperature in order to pro-
vide cooling at a high load of the engine.

Auxiliary heating (auxiliary heating and ventilation)
 Introduction
This chapter contains information on the following subjects:
Switching on/off
116
Radio remote control
116
Conditions for the functioning of auxiliary heating (Aux. heating and ventilation),
hereinafter referred to only as auxiliary heating (Aux. heating).
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon 
is not lit in the display of the
instrument cluster).
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).
Auxiliary heating (parking heating)
The auxiliary heating (parking heating) 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 auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
The auxiliary heating (parking heating) also warms up the engine.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank. The coolant heats air flowing into the passenger compart- ment (as long as the blower fan speed B
» Fig. 108 on page 108 or
C
» Fig. 110
on page 112 is not set to zero).
WARNING■ The auxiliary heater (independent vehicle heater) must never be operated in
closed rooms (e.g. garages) – risk of poisoning!■
The auxiliary heating (parking heating) must not be running during refuelling
– risk of fire.
■
The exhaust pipe of the auxiliary heating is located underneath the vehicle.
Therefore, if you wish to operate the auxiliary heating (parking heating), do
not park the vehicle in such a way that the exhaust gases can come into con-
tact with highly flammable materials (e.g. dry grass) or easily inflammable sub-
stances (e.g. spilt fuel) – risk of fire.
CAUTION
■ The running auxiliary heating (parking heating) consumes fuel from the vehicle
tank and automatically controls the filling level. If only a low quantity of fuel is
present in the fuel tank, the auxiliary heater switches itself off.■
The exhaust pipe of the auxiliary heating, which is located underneath the vehi-
cle, must not be clogged up and the exhaust flow must not be blocked.
■
If the auxiliary heating 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.
Note
■ The auxiliary heating (aux. heating) switches on the blower B » Fig. 108 on
page 108 or C » Fig. 110 on page 112 only 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.
■
The air inlet in front of the windscreen must be free of e.g. ice, snow or leaves
to ensure that the auxiliary heating and cooling system 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 .

115Heating and air-conditioning

CAUTION■Just filling the tank once with diesel fuel that does not comply with the stand-
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!■
If a different fuel other than diesel fuel, which complies to the above mentioned
standards (e.g. petrol) is used by mistake do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur! We recommend that you
have the fuel system cleaned by a specialist garage.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ Your vehicle cannot be operated with biofuel RME, therefore this fuel must not
be refuelled and driven. The use of biofuel RME can cause considerable damage
to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents) into the diesel. This can result in considerable damage to parts of the en-
gine or the exhaust system.

218WARNINGWhen working in the engine compartment, injuries, scolding, accident or fire
hazards may arise. For this reason, it is essential to comply with the warning
instructions stated below and with the general applicable rules of safety. The
engine compartment of your car is a hazardous area!WARNINGBefore beginning work in the engine compartment, please read the following
advice.■
Turn off the engine and withdraw the ignition key.
■
Firmly apply the handbrake.
■
If the vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if the vehicle is fitted with an automatic gearbox, move the selec-
tor lever into position P.
■
Allow the engine to cool.
■
Never open the bonnet if you can see steam or coolant flowing out of the
engine compartment – risk of scalding! Wait until the steam or coolant has
stopped escaping.
WARNINGWhile working in the engine compartment, please read the following advice.■Keep children clear of the engine compartment.■
Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running!
■
Do not touch any hot engine parts – risk of burns!
■
The coolant additive and thus all of the coolant is harmful to your health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the en-
gine is still warm. The cooling system is pressurized!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot cool-
ant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes with
clear water and contact a doctor as soon as possible.
■
Always safely store the coolant additive in its original container out of the
reach of children – risk of poisoning!
■
If coolant is swallowed, consult a doctor immediately.
■
Do not leave any items (e.g. cloths or tools) in the engine compartment.
■
Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite! 

The coolant consists of water with a concentration of coolant additive. This mix-
ture guarantees antifreeze protection, protects the cooling/heater system
against corrosion and prevents the formation of scale.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries the concentration of coolant additive should be at least 40 %.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries the concentration of coolant additive should be at least 50 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased up to a maximum of 60 % (antifreeze
protection down to approx. -40 °C).
When refilling, only use antifreeze with the name specified on the coolant expan-
sion tank » Fig. 185 on page 222.WARNING■
The engine compartment of your car is a hazardous area. While working in
the engine compartment, be sure to observe the following warn- ings » page 215 .■
Do not continue your journey, if for some reason it is not possible to top
up the coolant under the prevailing conditions! Switch off the engine and seek
assistance from a specialist garage.
CAUTION
■ The amount of coolant additive in the coolant must never be allowed to be less
than 40 %.■
Over 60 % of coolant additive in the coolant reduces the antifreeze protection
and coolant effectiveness.
■
A coolant additive that does not comply with the correct specifications can sig-
nificantly reduce the corrosion protection.
■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 185 on page 222.
■
If a fault causes the engine to overheat, we recommend visiting a specialist ga-
rage, as otherwise serious engine damage may occur.
