Maintenance requirements
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For full details of your maintenance schedule, refer to the “To yota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself maintenance?
Many maintenance items are easy to do yourself if you have a li ttle
mechanical ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tool s 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 Toyota retailer or T oyota
authorized repairer, or any reliable repairer. Any authorized T oyota retailers
or repairer will keep a record of maintenance, which could be u seful should
you ever require Warranty Service. Should you choose to select a qualified
and equipped professional other than an authorized Toyota repai rer to ser-
vice or maintain your vehicle, we recommend that you request th at a
record of maintenance be kept.
To ensure safe and economical driving, day-to-day care and reg-
ular maintenance are essential. Toyota recommends the follow-
ing maintenance:
