MAINTENANCE
You are responsible for performance of the required maintenance indi-
cated in the Owner's Manual and the Scheduled Maintenance Guide.
Toyota will not deny a warranty claim solely because you do not have
records to show that you maintained your vehicle. However, any failure
or noncompliance caused by lack of maintenance is not covered by this
warranty.
When maintenance and repairs are paid for by you, these services
may be performed by you or by any automotive service provider you
choose. Toyota will not deny a warranty claim simply because you
used a service provider other than a Toyota dealership for mainte-
nance and repairs. However, any failure or non-compliance caused by
improper maintenance or repairs is not covered by this warranty.
Federal Emission Control Warranty
REPLACEMENT PARTS
To ensure optimum performance and maintain the quality built into
your vehicle's emission control systems, Toyota recommends the use of
Genuine Toyota Parts when servicing or repairing the systems.
Warranty coverage is not dependent upon the use of any particular
brand of replacement parts and you may elect to use non–Genuine
Toyota Parts for maintenance and repairs. However, use of replace-
ment parts that are not equivalent in quality to Genuine Toyota
Parts may impair the effectiveness of the emission control systems.
If you use replacement parts that have maintenance or replacement
schedules different from those of Genuine Toyota Parts, you must follow
the maintenance and replacement schedules for the parts you are using.
In addition, you should ensure that such parts are warranted by their
manufacturers to be equivalent to Genuine Toyota Parts.
