If you must run the engine while
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:
Working under the hood with the
engine running is dangerous. It
becomes even more dangerous when
you wear jewelry, loose clothing or
have long hair or a long beard.
Either can become entangled in
moving parts and result in injury.
Pull over to a safe location, then
switch the ignition off and make sure
the fan is not running before
attempting to work near the cooling
fan:
Working near the cooling fan when it is
running is dangerous. The fan could
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.
Do not leave items in the engine
compartment:
After you have finished checking or
doing servicing in the engine
compartment, do not forget and leave
items such as tools or rags in the
engine compartment.
Tools or other items left in the engine
compartment could cause engine
damage or a fire leading to an
unexpected accident.
