This section is prepared for technicians who have attai ned a high level of skill and experience in repairing col-
lision-damaged vehicles and also use modern servic e tools and equipment. Persons unfamiliar with body
repair techniques should not attempt to repair collision-damaged vehicles by using this section.
Technicians are also encouraged to read Body Repair M anual (Fundamentals) in order to ensure that the orig-
inal functions and quality of the vehicle can be mainta ined. The Body Repair Manual (Fundamentals) contains
additional information, including cautions and warning, that are not including in this manual. Technicians
should refer to both manuals to ensure proper repairs.
Please note that these information are prepared for wo rldwide usage, and as such, certain procedures might
not apply in some regions or countries.
