Checking coolant level
1.
Do not open the engine hood before the
engine has cooled down.
2.
Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3.
The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4.
If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.
Turn the cap until there is an audible click.
6.
If the loss of coolant is substantial, have the
cause eliminated as soon as possible.
