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 drivin g, day-to-day care and regular main-
tenance are essential. It is the owne r’s responsibility to perform regular
checks. Lexus recommends the following maintenance:
■ General maintenance
General maintenance should be performed on a daily basis. This
can be done by yourself or by a Lexus dealer.

according to the maintenance schedule. For details about maintenance items and schedules, refer to the “War-
ranty and Service Guide”, “Owner’s Manual Supplement” or “Scheduled

ranty coverage. The use of Lexus Repair Manuals is recommended.
For details about warranty coverage, refer to the separate “Owner’s
Guide”, “Warranty and Service Guide”, “Owner’s Manual Supplement”
