The Climatronic in automatic mode ensures the best-possible setting of the tem-
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 82, Control elements .
The engine is running.
The outside temperature is above approx. +2 °C.
The cooling system is switched off at excessive coolant temperatures in order to guarantee a cooling effect when the engine is under a high load.
Note
We recommend that you have Climatronic cleaned by a specialist garage once ev-
ery year.Control elementsFig. 80

163Inspecting and replenishing

Oil level within range CThe engine must be topped up with oil so that the oil level at least reaches the
range B
.
The engine consumes a little oil. The oil consumption may be as much as 0.5 l/
1 000 km depending on your style of driving and the conditions under which you
operate your vehicle. Consumption may be slightly higher than this during the
first 5 000 kilometres.
The oil level must be checked at regular intervals. We recommend after each time
you refuel or prior to making a long journey.
We recommend maintaining the oil level within the range
A
, but not above , if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun- tain pass.
If the oil level is too low, this will be indicated by an indicator light in the instru- ment cluster » page 16,
Engine Oil . Check the oil level using the dipstick as
soon as possible. Add oil accordingly.
CAUTION
The oil level must not exceed level A » Fig. 136 - risk of damaging the exhaust
system!
Replenishing
First read and observe the introductory information and safety warn-
ings
on page 166.
›
Check the oil level » page 167.

The coolant consists of water with coolant additive. This mixture guarantees anti- freeze protection, protects the cooling/heater system against corrosion and pre-
vents 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 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 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 antifreeze with the name specified on the coolant expan- sion tank » Fig. 137 on page 169.
168General Maintenance

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 162.■
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 protection
and cooling effect.■
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. 137 on page 169.
■
If a fault causes the engine to overheat, we recommend visiting a specialist ga-
rage, as otherwise serious engine damage may occur.

169Inspecting and replenishing

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
First read and observe the introductory information and safety warn-
ings
on page 168.
Only top up with new coolant.
