Maintenance Records
Maintaining your vehicle according to the recommendations 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 performed.
The scheduled maintenance log in this booklet can help you document this
information. If you sell your vehicle, be sure to give your maintenance records to
the new owner.
Toyota will not deny a warranty claim solely because you do nothave records
to show that you maintained your vehicle. However, damage or failures caused
by lack of proper maintenance are not covered under warranty.
Maintenance Providers
Maintenance and repair services may be performed by you or by any automotive
service provider you choose. Toyota will not deny a warranty claim solely because
you used a service provider other than a Toyota dealership for maintenance and
repairs. However, damage or failures caused by improper maintenance or repairs
are not covered under warranty.
Dealer-Recommended Maintenance
Your dealer may recommend more frequent maintenance 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 Toyota warranty coverages, see the booklet
entitled

Determining Your Vehicle’s Maintenance Needs
Determining the Proper Maintenance Interval
Depending on your circumstances, you should obtain maintenance for your
Toyota every 5,000 miles or every 7,500 miles. Follow these guidelines to
determine which interval to use.
5,000-Mile Intervals
Use 5,000-mile intervals if you primarily operate your vehicle under any of
the following conditions:
•Driving on unpaved or dusty roads.
•Towing a trailer or using a car-top carrier.
•Repeated trips of less than five miles in temperatures below freezing.
7,500-Mile Intervals
Use 7,500-mile intervals if you primarily operate your vehicle under conditions
other than those listed above.
Note: If you drive your vehicle under any of the special operating conditions
noted below, you may need to perform specific services at 5,000-mile intervals.
See the 5,000-mile maintenance charts for details.
Special Operating Conditions
In addition to standard maintenance items, the scheduled maintenance log
indicates services that should be performed on vehicles that are driven under
especially demanding conditions. Specific conditions require specific services,
as indicated on the following page. The scheduled maintenance log indicates
at which mileage/time intervals each service should be performed.
You should perform these additional maintenance services if you drive primarily
under any of the conditions noted. If you drive only occasionally under these
conditions, it is not necessary to perform the additional services.

Following the Charts
The scheduled maintenance log identifies the maintenance required at each
mileage interval and corresponding time interval based on mileage of 1,250
miles per month. If you drive more than 1,250 miles per month, you should
obtain maintenance at the indicated mileage interval rather than the indicated
time interval.
The maintenance log charts are colored differently for Cars/Sienna and SUVs/Trucks.
Be sure to follow the appropriate charts for your vehicle.
See page 16 to determine the propermaintenance interval for your vehicle.
Cars and Sienna
If you choose 5,000-mile intervals, follow the instructions below the light blue
bars in the “Cars and Sienna” charts, such as this one:
5,000 Miles or 4 Months
If you choose 7,500-mile intervals, follow the instructions below the dark blue
bars in the “Cars and Sienna” charts, such as this one:
7,500 Miles or 6 Months
At15,000-mile increments, the 5,000-mile and 7,500-mile intervals coincide.
Therefore, the colored bars appear together, as in this example:
