Maintenance requirements
■Repair and replacement
It is recommended that genuine Lexus parts be used for repair to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair
shop other than a Lexus dealer performs repairs, confirm the warranty coverage.
To ensure safe and economical driving, day-to-day care and regular main-
tenance is essential. It is the owner’s responsibility to perform regular
checks. Lexus recommends the following maintenance.
■General maintenance
Should be performed on a daily ba sis. This can be done by yourself
or by a Lexus dealer.
■ Scheduled maintenance
Should be performed at specified intervals according to the mainte-
nance schedule.
For details about maintenance items and schedules, refer to the “War-
ranty and Services Guide/Owner’s Manual Supplement/Scheduled
Maintenance”.
■Do-it-yourself maintenance
You can perform some maintenance procedures yourself.
Please be aware that do-it-yourself maintenance may affect war-
ranty coverage.
The use of Lexus Repair Manuals is recommended.
For details about warranty coverage, see the separate “Owner’s Guide”,
“Warranty and Services Guide”, “Owner’s Manual Supplement” or
“Warranty Booklet”.
