off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.

engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop your
engine if it overheats, and get out
of the vehicle until the engine
is cool.
Notice:
If the engine catches fire
because of being driven with no
coolant, your vehicle can be
badly damaged. The costly
repairs would not be covered by
