The Climatronic in automatic mode ensures the best possible setting for the
temperature of the air flowing out, the blower stage and air distribution.
The system also takes sunlight into account, which eliminates the need to al-
ter the settings manually.
The cooling system operates only if the following conditions are met. The cooling system is switched on » page 112.
The engine is running.
The outside temperature is above approximately +2 °C.
The blower is switched on.
The cooling system is switched off at a high coolant temperature in order to
provide cooling at a high load of the engine.
Aeration of the vehicle when ignition is switched off
On models fitted with power sliding/tilting roof with solar cells, the fresh air
blower is automatically switched over to “solar mode” if the sun rays are suffi- cient after switching off the ignition. The solar cells on the sliding/tilting roof
deliver power for the fresh air blower. This supplies the interior of the car with
fresh air.
For an optimum ventilation, the air outlet vents 2 and 3 must be
opened » Fig. 123 on page 110 .
The ventilation functions only when the sliding/tilting roof is fully closed.
Note■ We recommend that you have Climatronic cleaned by a specialist garage
once every year.■
During operation of the Climatronic, an increase in engine idle speed can oc-
cur under certain circumstances in order to ensure adequate heating comfort.
■
On vehicles equipped with a factory fitted radio or radio navigation system,
the Climatronic information is also shown on their displays. This function can
be switched off, see » operating instructions for the radio or navigation sys-
tem .

116Operation
At both end positions, Climatronic functions at maximum cooling/heating out-
put and the temperature is not regulated.
CAUTION
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when get-
ting out of the vehicle, can cause susceptible individuals to catch a cold.
Recirculation mode - Version 1
Recirculated air mode prevents polluted air outside the vehicle from getting in-
to the vehicle, for example when driving through a tunnel or when standing in
a traffic jam.
If a considerable increase in concentration of pollutants is recognised by the air quality sensor , recirculated air mode will temporarily be switched off.
If the concentration of pollutants decreases to the normal level, the air distri-
bution control is automatically switched off so that fresh air can be guided into
the vehicle interior.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior.
When the automatic air distribution control is switched on, an air quality sen-
sor measures the concentration of pollutants in the drawn in air.

CAUTION■Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system!■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Engine parts could be significantly damaged!
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with biofuel RME, therefore this fuel must
not be filled in the tank and used for driving the vehicle. 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
engine or the exhaust system!

The coolant consists of water with coolant additive. This mixture guarantees
antifreeze protection, protects the cooling/heater system against corrosion
and prevents lime formation.
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 countries, 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 countries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-
centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the same antifreeze identified on the coolant expan-
sion vessel » Fig. 167 on page 192 .
WARNINGThe engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en- gine compartment » page 186.
CAUTION
■
Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
ventilate - there is a risk of engine damage,
do not continue driving! Switch
off the engine and seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specifications can
significantly reduce the corrosion protection.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 167 on page 192 .
■
If a fault causes the engine to overheat, we recommend visiting a specialist
garage, as otherwise serious engine damage may occur.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.

Open the bonnet.
›
Check the level of coolant in the coolant expansion bottle. » Fig. 167.
Check the coolant level only when the engine is cold.
ABIf the engine is warm, the test result may be inaccurate. The level can also be
above the mark A » Fig. 167 .
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light
illuminating in the instrument cluster » page 36,
Cool-
ant . We still recommend inspecting the coolant level directly at the reservoir
from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a specialist
garage.
Replenishing
Read and observe
and on page 191 first.
The coolant expansion tank must always contain a small amount of cool-
ant » page 191, in section Introduction .
