140 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 their closed origi-
nal containers and in a location which is
out of reach of children. Antifreeze and
anti-corrosion agents are inflammable.
For this reason, do not spill them on hot
engine parts. They could ignite and
cause serious burns. Comply with the
instructions on the containers.

Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze with corrosion inhib-
itor.
