Operational problemsRead and observe
and on page 108 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 215 .
› The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot » page 29.
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.

The cooling system operates only if the following conditions are met. The cooling system is switched on » page 110.
The engine is running.
The outside temperature is above approx. +2 °C.
The blower switch is switched on (positions 1-4).
Under certain circumstances, air at a temperature of about 5 °C can flow out of
the vents when the cooling system is switched on.
If the desired interior temperature can also be achieved without activating the
cooling system, fresh air mode should be selected.
The cooling system is switched off at a high coolant temperature in order to
provide cooling at a high load of the engine.
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.Note■ We recommend that you have the air conditioning system cleaned by a spe-
cialist garage once every year.■
During operation of the air conditioning, an increase in engine idle speed may
occur under certain circumstances in order to ensure sufficient heating com-
fort.

The Climatronic in automatic mode ensures the best-possible setting of the
temperature of the outflowing air, 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 110.
The engine is running.
The outside temperature is above approx. +2 °C.
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 sollar cells, the fresh air
blower is automatically switched over to “solar mode” if the sun ray's 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. 122 on page 108 .
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 .

114Operation

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 by mistake do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur! We rec-
ommend that you have the fuel system cleaned by a specialist garage.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with bio fuel 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. 164 on page 188 .WARNING■
The 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 182.■
Do not continue your journey if for some reason it is not possible to fill
with coolant under the current circumstances 
. Switch off the engine and
seek assistance from a specialist garage.
CAUTION
■ 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. 164 on page 188 .
■
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.

the coolant must be topped up.
Checking the level
›
Switch off the engine.
›
Open the bonnet.
›
Check the level of coolant in the coolant expansion bottle. » Fig. 164.
Check the coolant level only when the engine is cold.
If the engine is warm, the test result may be inaccurate. The level can also be
above the mark
A
» Fig. 164 .
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light  lighting up in the instrument cluster
» page 34,
 Coolant
.
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 187 first.
Only top up with new coolant.
›
Switch off the engine.
›
Allow the engine to cool.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the
cap carefully .
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available in an
emergency. In this case, use just water and have the correct mixing ratio of
water and coolant additive restored by a specialist garage as soon as possible.
1)
The coolant capacity is approximately 1 l greater on vehicles that are fitted with an auxiliary heater (aux-
iliary heating and ventilation).
