Coolant

Do not add coolant to the cooling
system when the engine is hot. If

you attempt to do so, escaping coolant
can cause burns.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in original containers
and in a location which is out of reach
of children. Antifreeze and anti-corro-
sion agents are inflammable. For this
reason, do not spill them on hot engine
parts. They could ignite and cause seri-
ous burns. Comply with the instructions
on the containers.

Checking the coolant level and
adding coolant

Check the coolant level when the
engine is cold, approx. 68

7/+206.

1. Open the cap for the expansion tank

by turning it slightly counterclock-
wise to allow accumulated pressure
to escape, then open

2. The coolant level is correct when the

upper end of the red float is at least
even with the upper edge of the filler
neck; see arrow. The end of the float
may stick out by a maximum of
3/4 in / 2 cm – that is, up to the sec-
ond mark on the float

3. If necessary, add coolant. If the cool-

ant is low, slowly add coolant until
the correct level is reached – do not
overfill.

Comply with the applicable envi-
ronmental laws regulating the dis-

posal of antifreeze agents with corro-
sion inhibitor.
