Maintenance requirements
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 Booklet” 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-yourself mechanic, we recommend that repairs and
maintenance be conducted by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional. Any authorized Lexus
dealer or repairer will keep a record of maintenance, which could be use-
ful 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.
To ensure safe and economical driving, day-to-day care and regu-
lar maintenance are essential. Lexus recommends performing the
following maintenance:
