Graphics for oil level in the centre display.
The oil level is checked using the electronic oil
level gauge in the centre display when the engine
is switched off.
NOTE
The system cannot directly detect changes
when the oil is filled or drained. The car must
have been driven approx. 30 km and have
been stationary for 5 minutes with the engine
switched off and on level ground before the
oil level indication is correct.
NOTE
If the right conditions for measuring the oil
level (time after engine shutdown, the car's
inclination, outside temperature, etc.) are not
met, then the message
No value available
will be shown in the centre display. This does
not mean that there is something wrong in
the car's systems.

Topping up coolant
The coolant cools the internal combustion
engine to the correct operating temperature. The
heat that is transferred from the engine to the
coolant can be used to heat the passenger com-
partment.
When topping up the coolant, follow the instruc-
tions on the packaging. Never top up with water
only. The risk of freezing increases with both too
little and too much coolant concentrate.
WARNING
Coolant can be very hot. If the coolant
requires topping up when the engine is at
operating temperature, unscrew the expan-
sion tank cap slowly to gently release the
overpressure.
