Scheduled maintenance should be perfor med at specified intervals according to

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 repair s and maintenance be conducted by any
authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer. Any
authorized Lexus retailer or re pairer will keep a record of maintenance, which could be useful should you ever require Warrant y Service. Should you choose to select a
qualified and equipped professional other th an an authorized Lexus repairer to ser-
vice or maintain your vehicle, we recommen d that you request that a record of main-
tenance be kept.
