MAINTENANCE
MAINTAINING YOUR WARRANTY
IMPORTANT MAINTENANCE
INFORMATION
It is especially important to both
routinely check your vehicle’s engine
oil level (once a month) and regularly
replace the engine oil and oil lter
(see the Maintenance Log section of
this booklet to determine how often
you should change your vehicle’s oil
and lter). Failure to do so can cause
oil starvation and/or oil gelling, which
can result in severe damage to your
vehicle and require costly repairs that
are not covered by the New Vehicle
Limited Warranty.
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 not have records
to show that you maintained your vehicle.
However, damage or failure caused by lack
of proper maintenance is 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 failure
caused by improper maintenance or
repairs is 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 to explain any recommended
maintenance not included in the scheduled
maintenance log.
For a complete description of Toyota
warranty coverages, see the Warranty
Information portion of this booklet.
