Maintenance requirements
â– 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 owne r’s responsibility to perform regular
checks. Lexus recommends the following maintenance.
â–  General maintenance
Should be performed on a daily basis. This can be done by yourself
or by a Lexus dealer.
â–  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”.
â–  Do-it-yourself maintenance
You can perform some maintenance procedures yourself. 
Please be aware that do-it-your self maintenance may affect war-
ranty coverage.
The use of Lexus service and 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”.
