MAINTENANCE
You are responsible for performance  
of the required maintenance indicated  
in the Owner’s Manual and this booklet. 
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 solely 
because you used a service provider  
other than a Toyota dealership for 
maintenance and repairs. However,  
any failure or noncompliance caused by 
improper maintenance or repairs is not 
covered by this warranty.
FEDERAL EMISSION CONTROL WARRANTY
*  Warranted until first required maintenance under terms of the California Emission Control Warranty.  8/80 = Covered for eight years or 80,000 miles, whichever occurs first.

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 replacement 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.
 
IF YOUR VEHICLE FAILS  
AN EMISSIONS TEST
If your vehicle fails an EPA-approved 
emissions test, you may make a claim  
under the Emission Performance Warranty. 
To do so, take your vehicle to an authorized 
Toyota dealership and present a copy  
of the emissions test report. Also, take  
your maintenance records in case they  
are needed.
If your claim qualifies for coverage, the 
dealership will repair your vehicle within  
30 days (unless a shorter period is  
required by law). If your claim is denied, 
Toyota will notify you in writing of the  
reason within the same period. If we fail  
to do so, we will repair your vehicle free 
of charge. The only exceptions allowed are 
when you request or agree to a delay, or  
when a delay is caused by factors beyond  
the control of Toyota or the dealership.

under the Emission Defect Warranty, see

vehicle to a Toyota dealership as soon as  
a problem exists. The warranty repairs  
should be completed in a reasonable  
amount of time, not to exceed 30 days.

MAINTENANCE
You are responsible for performance of the 
required maintenance indicated in the  
Owner’s Manual and this booklet. 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 solely 
because you used a service provider  
other than a Toyota dealership for 
maintenance and repairs. However,  
any failure or noncompliance caused by 
improper maintenance or repairs is not 
covered by this warranty.
