Topping up the engine oil

compartment: Engine oil
filler cap
–Unscrew cap from oil filler opening ⇒ Fig. 248.
–Carefully put in the specified grade of oil ⇒ page 236, adding
0.5 litres at a time.
–After two minutes, check the oil level once again ⇒ page 237.
–Where necessary, add more engine oil.
–Replace the oil filler cap carefully and push the dipstick all the
way in.
WARNING
●When refilling with oil, make sure no oil falls onto hot engine parts.
Failure to comply could result in fire.
●Wash your skin thoroughly if it comes into contact with engine oil.
CAUTION
●The oil level must never be above area a. This could damage the cata-
lytic converter or the engine. Contact a specialised workshop to drain the
engine oil if necessary.
●No additives should be used with engine oil. Any damage caused by the
use of such additives would not be covered by the factory warranty.
For the sake of the environment
●Oil must not be disposed of in the drain or on the ground.
●Always observe legal requirements when disposing of empty oil canis-
ters.
Cooling system
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25°C (-13°F) and protects the light alloy parts of the cooling system against
corrosion. It also prevents scaling and considerably raises the boiling point
of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity.
