Service Agreements and Pre-Paid Maintenance
Extended Service Coverage
Toyota vehicle service agreements provide protection against unexpected repairs
formechanical breakdown of covered components beyond the factory warranty.*
They also protect you from increases in the cost of covered repairs. In addition,
many plans include benefits such as towing, substitute transportation and travel
protection with lodging and meals.
Because they are factory-backed, Toyota service agreements are accepted at all
Toyota dealerships in the United States and Canada. That means repairs are made
only by factory-trained technicians using Genuine Toyota Parts.
Toyota Financial Services offers several levels of service agreement coverage, each
with a variety of time and mileage options.
**Your Toyota dealer can help you
select the coverage that best meets your needs.
Pre-Paid Maintenance
An excellent way to make sure your Toyota receives the recommended mainte-
nance — and to protect yourself from increases in vehicle service costs — is to
pay for maintenance services in advance.
Toyota Auto Care pre-paid maintenance plans are available for both new and
used vehicles. Benefits include oil-and-filter changes, lubrication of key chassis
parts and a 19-point vehicle inspection at each service interval. In addition, you
receive 24-hour roadside assistance, timed service reminders and a computerized
history of each service visit. The Premium Plan (available for new vehicles) also
includes tire rotations and factory-recommended maintenance at service inter-
vals of 15,000, 30,000 and 45,000 miles.
Toyota Auto Care plans offer two coverage levels as well as several options for
service intervals, time and mileage. Ask your Toyota dealer to help you select
the options that are best for you.
Vehicle service agreements are offered by Toyota Motor Insurance Services, Inc., dba Toyota Motor
Services Company in certain states. In Florida, offered by Toyota Motor Insurance Company.
Toyota Financial Services is a service mark of Toyota Motor Insurance Services, Inc.*

General Maintenance Information16
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.
Following the Maintenance Log 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.

General Maintenance Information17
Determining Your Vehicle’s Maintenance Needs
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.

15,000 Miles or 12 Months
SUVs and Trucks
If you choose 5,000-mile intervals, follow the instructions below the gold bars
in the “SUVs and Trucks” 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 “SUVs and Trucks” charts, such as this one:
7,500 Miles or 6 Months

the colored bars appear together, as in this example:
15,000 Miles or 12 Months
15,000 Miles or 12 Months
