Checking and topping up fluids
Depending on how you drive and the conditions
in which the car is used, oil consumption can be
up to 0.5 ltr./1000 km. Oil consumption is likely
to be higher for the first 5000 km. For this rea­
son the engine oil level must be checked at regu­
lar intervals, preferably when filling the tank and
before a journey.
Topping up the engine oil c:e:;,:
Fig. 217 Engine compartment: Engine oil filler cap
... Switch off the engine.
... Unscrew cap "t=1'l from oil filler opening
qfig. 217, qpage 238, Fig. 215.
... Carefully add 0.5 litres of suitable oil
qpage 239.
... After two minutes check the oil level once again
q page 239, Checking the engine oil level.
... If the oil level is too low, add more engine oil.
... Replace the oil filler cap carefully and push the
dipstick all the way in.

WARNING
- Ensure that no oil comes into contact with
hot engine components when topping up:
this could cause a fire.
- Wash your skin thoroughly if it comes into
contact with engine oil.

CAUTION
- The oil level must never be above area@, as
this may result in damage to the catalytic
converter or to the engine. Contact a quali­
fied workshop to extract the engine oil if
necessary.
- No additives should be used with engine oil.
Any damage caused by the use of such addi-

CD
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant level is monitored via a warning lamp
on the infotainment display qpage 12. However,
we recommend that it should be checked occa­
sionally.
If you do need to top up the coolant, use a mix­
ture of water and coolant additive. We recom­
mend mixing coolant additive with distilled wa­
ter .
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the fol­
lowing coolant additives. It is possible to mix
these additives.
Coolant additive
G12++
G13
Only if the above
grades are not availa-
ble:
G12+
The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too low, the coolant
can freeze and cause engine damage.
