perature is below 100 degrees C.

(even stopped and the ignition switched off), the cooling fan could operate at any time. Topping up the
cooling system
The coolant level
should be between
the
MAX and
MIN marks on the
header tank.
Top up the level. If you have to
add more than 1 litre, you should
have the cooling system checked

correctly
Note: The necessity to top up
frequently would indicate a mal-
function that should be checked at
the earliest opportunity.

particle filter, the cooling fan may
operate for some ten minutes after
the engine has stopped.
