Maintenance and care
IS250_EE(OM53C51E)7-2. Maintenance
Scheduled maintenance should be performed at specified intervals according to
the maintenance schedule.
For details about maintenance items and schedules, refer to the “Lexus Service Book-
let” or “Lexus Warranty Booklet”.
What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little mechanical
ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tools and skills. These
are best performed by qualified technicians. Even if you’re an experienced do-it-your-
self mechanic, we recommend that repairs and maintenance be conducted by any
authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional. Any authorized Lexus dealer or repairer will keep a record of maintenance,
which could be useful should you ever require Warranty Service. Should you choose
to select a qualified and equipped professional other than an authorized Lexus
repairer to service or maintain your vehicle, we recommend that you request that a
record of maintenance be kept.
