Maintenance

Maintenance, replacement or repair of emission
control devices and systems may be performed by
any repair establishment or individual; however,
warranty repairs must be performed by a dealer or
s e r v i c e c e n t e r a u t h o r i z e d b y M a r u y a m a
Manufacturing Company, Inc. The use of parts that
are not equivalent in performance and durability to
authorized parts may impair the effectiveness of the
emission control system and may have a bearing on
the outcome of a warranty claim.
Maintenance on today's low-emission engines is
even more critical for longest life and best
performance. particularly critical are air and fuel
filters, spark plug heat range, cooling air intake
area and proper gaps of coil and plug.
