working under the hood, make
certain that you remove all jewelry
(especially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose clothing
before getting near the engine or
cooling fan which may turn on
unexpectedly:

switch the ignition off and make sure
the fan is not running before
attempting to work near the cooling
fan:

continue running indefinitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.

compartment:

doing servicing in the engine
compartment, do not forget and leave

compartment could cause engine
damage or a fire leading to an
unexpected accident.
