Maintaining your vehicle according to the recommen-
dations in this booklet is required to ensure that your
warranty coverage remains intact. You should keep
detailed records of vehicle maintenance, including
date of service, mileage at time of service and a
description of service and/or parts installation per-
formed. The maintenance logs in this booklet are a
good place to record this information. If you sell your
vehicle, be sure to give your maintenance records to
the new owner.
Lexus will not deny a warranty claim solely because
you do not have records to show that you maintained
your vehicle. However, damage or failures caused by
lack of proper maintenance are not covered under
warranty.
Maintenance and repair services may be performed by
you or by any automotive service provider you choose.
Lexus will not deny a warranty claim solely because
you used a service provider other than a Lexus dealer-
ship for maintenance and repairs. However, damageor failures caused by improper maintenance or repairs
are not covered under warranty.
Your dealer may recommend more frequent mainte-
nance intervals or more maintenance services than
those listed in the scheduled maintenance log. These
additional services are not required to maintain your
warranty coverage. Ask your dealer for an explanation
of any recommended maintenance not included in the
scheduled maintenance log.
For a complete description of Lexus warranty
coverages, see pages 16–33 of this booklet.MAINTENANCE

Introduction
To ensure that your vehicle receives first-quality ser-
vice and factory-authorized parts, Lexus recommends
having maintenance performed by an authorized
Lexus dealership. To locate your nearest authorized

Lexus dealership technicians are experts in the mainte-
nance and repair of Lexus vehicles. They stay current

National Institute for Automotive Service Excellence.
Additionally, when you have your vehicle serviced at a
Lexus dealership, your service information is recorded
in the Lexus National Service History database. This
is the first database of its kind in the automotive
industry. It can be accessed by any Lexus dealership inthe U.S. — a great convenience if you relocate or need
to have your vehicle serviced while traveling.

Determining Your Maintenance Interval:
Months vs. Mileage
Lexus recommends obtaining scheduled maintenance
for your vehicle every six months or 5,000 miles,
whichever occurs first.
For example: If at six months you have driven less than 5,000
miles, you should obtain maintenance at six months;
don’t wait until 5,000 miles. If you drive 5,000 miles in less than six months, you
should obtain maintenance at 5,000 miles; don’t wait
until six months.
Be sure to keep an eye on your mileage so that you
obtain maintenance when recommended. If you are a
low-mileage driver, mark your calendar to remind your-
self to obtain maintenance every six months. Complimentary First Scheduled Maintenance
