Read and observe on page 30 first.
The display » Fig. 24 provides information on the engine coolant temperature.
The fuel gauge only works if the ignition is switched on.
Cold range
If the pointer is still in the left area of the scale, this indicates that the engine
has not yet reached its operating temperature. Avoid high speeds, full throttle
and high engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the middle of the scale A
» Fig. 24 . At very high ambient tempera-
tures or heavy engine loads, the pointer may move even further to the right.
High temperature range
If the pointer reaches the red area of the scale, the coolant temperature is too
high.

The heating and air conditioning ventilate and heat the vehicle interior. The air
conditioning system also cools and dehumidifies the vehicle interior.
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
The cooling system operates only if the following conditions are met. The cooling system is switched on.
The engine is running.
The outside temperature is above approx. +2 °C.
The blower is switched on.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The cooling system prevents the windows from misting up during
the cold season of the year.
It is possible to briefly activate recirculated air mode to enhance the cooling
effect » page 117 .
WARNING■
For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting.■
The blower should always be on to prevent the windows from misting up.
WARNING (Continued)■ Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.■
To reduce health risks (e.g. common colds), the following instructions for
the use of the cooling system are to be observed. ■The difference between the indoor temperature and the outdoor air
temperature should not be greater than about 5 ° C.
■ The cooling system is to be turned off about 10 minutes before the end
of the journey.
■ Once a year, a disinfection of the air conditioner or the Climatronic is to
be carried out by a specialist company.
CAUTION
■ The air inlet in front of the windscreen must be free of e.g. ice, snow or
leaves to ensure that the heating and cooling system operates properly.■
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!
■
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.
Note
The used air streams out through the vents in the luggage compartment.
Air outlet vents

116Using the system

■As soon as the windscreen mists up, press the symbol button . Press the
button once the windscreen has demisted.■
During operation of the Climatronic, an increase in engine idle speed can oc-
cur under certain circumstances in order to ensure adequate heating comfort.
Efficient handling of the cooling system
Read and observe
and on page 116 first.
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be on if the windows are open.
For the sake of the environment
Pollutant emissions are also lower when fuel is being saved » page 136.
malfunctions
Read and observe
and on page 116 first.
If the cooling system does not operate at outside temperatures higher than
+5 °C, there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 229 .
› The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot » page 32.
If you are not able to resolve the operational problem yourself, or if the cooler
output has reduced, switch off the cooling system and seek assistance from a
specialist garage.
Auxiliary heating (auxiliary heating and ventilation)
Introduction
This chapter contains information on the following subjects:
Switching on/off
122
Radio remote control
123Conditions for the functioning of auxiliary heating (auxiliary heating and venti-
lation), hereinafter referred to only as auxiliary 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 can be used when both when stationary, when the en-
gine is switched off, to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heater functions in connection with the air-conditioning system
or Climatronic.
The auxiliary heating also warms up the engine.
The auxiliary heating warms up the coolant by combusting fuel from the vehi-
cle tank. This heats the air flowing into the passenger compartment (if the
blower is turned on).
The heater is switched on or off automatically depending on the ambient con-
ditions to give the best possible conditions for the engine running and the in-
terior heating.
The automatic switching on and off of the heater can be turned off by a spe-
cialist garage.WARNING■ The auxiliary heating must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the heater, do not park the car in places
where the exhaust fumes can come into contact with flammable materials
such as dry grass, undergrowth, leaves, spilled fuel etc. - risk of fire.
