Changing engine oil
First read and observe the introductory information and safety warn-
ings on page 108.
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
» page 10, Service Interval Display.CAUTION
Additives must not be added to the engine oil – risk of causing considerable dam-
age to parts of the engine! Damage, which results from such product, are exclu-
ded from the warranty. Note
If your skin has come into contact with oil, it must be washed thoroughly. ÐCoolant
First read and observe the introductory information and safety warn-
ings on page 108.
The cooling system is filled with a coolant in the factory.
The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture provides antifreeze protection down to -25
°C and also protects the
cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
The concentration of coolant must therefore not be reduced by adding water dur-
ing the summer months or in countries with a warm climate. The concentration of
coolant additive in the coolant must be at least 40 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased up to 60 % (antifreeze protection down
to approx. -40 °C). The antifreeze protection tails off above that concentration.
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 %.
When refilling, we only recommend you use the same antifreeze written on the
antifreeze expansion tank » Fig. 101 on page 112.

■ Other coolant additives that do not comply with the correct specifications can
above all significantly reduce the anticorrosion effect.
■ Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage! Ð Checking the coolant level
Fig. 101
Engine compartment: Coolant
expansion reservoir
First read and observe the introductory information and safety warn-
ings on page 108.
The coolant expansion bottle is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 110.
› Check the level of coolant in the coolant expansion bottle
» Fig. 101. The cool-
ant level when the engine is cold must lie between the
“MIN” and “MAX” mark-
ings. The level may also rise slightly above the “MAX” marking when the engine
is warm.
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 16, Coolant tem-
perature/coolant level . We still recommend inspecting the coolant level directly
at the reservoir from time to time. £
