WA R N I N G
Do not perform maintenance work if you lack sufficient knowledge and experience or the
proper tools and equipment to do the work. Have maintenance work done by a qualified
technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can be
seriously injured while performing some maintenance procedures.
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 ru nning is dangerous. It becomes even more
dangerous when you wear jewelry, loose clot hing 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 runn ing 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 co mpartment could cause engine damage or a
fire
leading to an unexpected accident.
