WARNING
Servicing a vehicle can be dangerous. If you have not received
service-related training, the risks of injury, property damage, and
failure of servicing increase. The recommended servicing procedures
for the vehicle in this workshop manual were developed with
Mazda-trained technicians in mind. This manual may be useful to
non-Mazda trained technicians, but a technician with our
service-related training and experience will be at less risk when
performing service operations. However, all users of this manual are
expected to at least know general safety procedures.
This manual contains "Warnings" and "Cautions" applicable to risks
not normally encountered in a general technician's experience.
They should be followed to reduce the risk of injury and the risk that
improper service or repair may damage the vehicle or render it unsafe.
It is also important to understand that the "Warnings" and "Cautions"
are not exhaustive. It is impossible to warn of all the hazardous
consequences that might result from failure to follow the procedures.
The procedures recommended and described in this manual are
effective methods of performing service and repair. Some require tools
specifically designed for a specific purpose. Persons using procedures
and tools which are not recommended by Mazda Motor Corporation
must satisfy themselves thoroughly that neither personal safety nor
safety of the vehicle will be jeopardized.
The contents of this manual, including drawings and specifications, are
the latest available at the time of printing, and
Mazda Motor Corporation
reserves the right to change the vehicle designs and alter the contents
of this manual without notice and without incurring obligation.
Parts should be replaced with genuine Mazda replacement parts or
with parts which match the quality of genuine Mazda replacement
parts. Persons using replacement parts of lesser quality than that of
genuine Mazda replacement parts must satisfy themselves thoroughly
that neither personal safety nor safety of the vehicle will be
jeopardized.
Mazda Motor Corporation is not responsible for any problems which
may arise from the use of this manual. The cause of such problems
includes but is not limited to insufficient service-related training, use of
improper tools, use of replacement parts of lesser quality than that of
genuine Mazda replacement parts, or not being aware of any revision
of this manual.
