WARNING - Loose
Clothing/Jewelry
Working under the hood with
the engine running is
dangerous. It is even more
dangerous when you wear
jewelry, long hair or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while
working under the hood, make
certain that you pull hair back,
remove all jewelry (especially
rings, bracelets, watches, and
necklaces) and all neckties,
scarves, and similar loose
clothing before getting near the
engine or cooling fans.
WARNING - Engine
Cooling Fans
Because your engine cooling
fans are electrically controlled,
they will run if the ignition
switch is on, even if the engine
is not running. This could cause
serious injury. To prevent this,
be sure the ignition is off, unless
you must run the engine while
performing maintenance or an
inspection.
