4-2. Maintenance Maintenance requirements To ensure safe and economical driving, day-to-day care and regular maintenance is essential. It is the owner's responsibility to perform regular checks. Lexus recommends the following maintenance. n General maintenance Should be performed on a daily basis. This can be done by yourself or by a Lexus dealer. n Scheduled maintenance Should be performed at specified intervals according to the maintenance schedule. For details about maintenance items and schedules, refer to the "Warranty and Services Guide/Owner's Manual Supplement/ Scheduled Maintenance". n Do-it-yourself maintenance You can perform some maintenance procedures yourself. Please be aware that do-it-yourself maintenance may affect warranty 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". n Repair and replacement It is recommended that genuine Lexus parts be used for repair to ensure performance 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. 374
