MAINTENANCE
139 You can be confident that your Lexus dealer’s service
department performs the best job to meet the maintenance
requirements of your vehicle.
Your copy of the repair order is proof that all required
maintenance has been performed for warranty coverage. And
if any problems should arise with your vehicle while under
warranty, your Lexus dealer will promptly take care of it. Again,
be sure to keep a copy of the repair order for any service
performed on your Lexus.
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. Simple instructions for how to perform them are
presented in Section 6.
If you are a skilled do-it-yourself mechanic, the Lexus service
manuals are recommended. Please be aware that
do-it-yourself maintenance can affect your warranty coverage.
See your Owner’s Guide or Warranty Booklet for the details.
