WARRANTY


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.


REPLACEMENT PARTS
To ensure optimum performance and
maintain the quality built into your
vehicle’s emission control systems,
Toyota recommends the use of Toyota
Genuine 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 parts that are not Toyota Genuine
Parts for maintenance and repairs.
However, use of replacement parts
that are not equivalent in quality to
Toyota Genuine 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 Toyota Genuine
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
Toyota Genuine Parts.

IF YOUR VEHICLE FAILS
A SMOG-CHECK TEST
If your vehicle fails a smog-check 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 smog-check 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.
For information on how to obtain service
under the Emission Defect Warranty, see
page 32, “Obtaining Warranty Service.”


REPAIR DELAYS
If a Toyota dealership is unable to
complete repairs on your vehicle within
30 days, you may have the repairs made
under Toyota’s provisions for emergency
warranty repairs. See page 32 for details.

GENERAL INFORMATION
You are responsible for ensuring that
your Toyota is operated and maintained
according to the instructions in the
Owner’s Manual and this booklet.
You should keep detailed records of
vehicle maintenance, since under some
circumstances they may be required for
warranty coverage. These records should
include date of service, mileage at time
of service and a description of service
performed and/or parts installed. For
your convenience, a maintenance log is
included in this booklet. If you sell your
vehicle, you should 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.

WHERE TO GO
FOR MAINTENANCE
You may have maintenance performed
on your vehicle by any qualified person
or facility. However, Toyota recommends
having maintenance performed by an
authorized Toyota dealership.
Toyota dealership technicians are specially
trained to maintain and repair Toyota
vehicles. They stay current on the latest
service information through Toyota
technical bulletins, service publications
and training courses. Many are also
certified through the Toyota Certification
Program, which involves a series of
rigorous written examinations. Feel free
to ask any Toyota dealership to show you
their technicians’ credentials.
You can be confident you’re getting the
best possible service for your vehicle
when you take it to a Toyota dealership.

WARRANTY


REPLACEMENT PARTS
Warranty coverage is not dependent
upon the use of any particular brand
of replacement parts. However, Toyota
recommends using only Toyota Genuine
Parts when you need to replace a part
on your vehicle. Like all Toyota products,
Toyota Genuine Parts are built to the
highest standards of quality, durability
and performance. They are also designed
to fit your vehicle’s exact specifications.
Your Toyota dealership maintains an
extensive inventory of Toyota Genuine
Parts to meet your vehicle service needs.
And because it is linked electronically to
Toyota’s Parts Distribution Centers, the
dealership has quick access to any parts
it may not have in stock.


Toyota Genuine Parts are covered by their
own warranty (see your dealer for details)
or the remainder of any applicable New
Vehicle Limited Warranty, whichever is
longer. Parts that are not Toyota Genuine
Parts, or any damage or failures resulting
from their use, are not covered by any
Toyota warranty.

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 filter
(see the Maintenance Log section of
this booklet to determine how often
you should change your vehicle’s oil
and filter). 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.

egular maintenance is essential
to obtaining the highest level of
performance, safety and reliability
from your Toyota. It can also increase
your vehicle’s resale value. This
booklet presents Toyota’s maintenance
recommendations in convenient checklists,
so you can easily see what type of
maintenance your vehicle needs and
document that the work was performed.
To ensure that your vehicle receives
first-quality service and parts, Toyota
recommends having maintenance
performed by an authorized Toyota
dealership. Toyota dealership technicians
are experts on Toyota vehicles, and they
use Toyota Genuine Parts designed to
your vehicle’s exact specifications. When
you go to a Toyota dealership, you can be
confident that they will use Toyota Genuine
Parts and have Toyota-trained technicians.
Miles or Months?
Toyota recommends obtaining scheduled
maintenance for your vehicle every
5,000 miles or six months, whichever
comes first.
For example:
• If you drive 5,000 miles in less than six
months, you should obtain maintenance
at 5,000 miles — don’t wait until six months.
• If at six months you have driven less
than 5,000 miles, you should obtain
maintenance at six months — don’t
wait until 5,000 miles.
Be sure to keep an eye on your mileage
so that you obtain maintenance when
recommended. If you are a low-mileage
driver, mark your calendar to remind
yourself to obtain maintenance every
six months.
Documenting Your Investment
To help you verify that you’ve invested in
proper maintenance, each maintenance
checklist includes space for your Toyota
dealership to certify that you obtained
Genuine Toyota Service for your vehicle.
The dealership may mark the dealer
service verification area with the following
stamp (which may be customized with the
dealership’s name):

Special Operating Conditions
In addition to standard maintenance items,
the maintenance log indicates services that
should be performed on vehicles that are
driven under especially demanding
conditions. These “special operating
conditions” and their required maintenance
items are clearly indicated in each chart.
NOTE:
You should perform these additional
maintenance services only if the
majority of your driving is done under
the special operating conditions
indicated. If you only occasionally
drive under these circumstances, it
is not necessary to perform the
additional services.
Engine Oil Selection
Please refer to your Owner’s Manual for the
specific oil viscosity rating recommended
for your vehicle/engine type.
Additional Maintenance
In addition to scheduled maintenance,
your Toyota requires ongoing general
maintenance, such as fluid checks and
visual inspections. These procedures are
explained in the “Maintenance and Care”
section of the Owner’s Manual. Be sure
to perform these procedures regularly to
ensure the most trouble-free operation
of your vehicle.
SuperChrome and
Alloy Wheel Care
If you purchased Genuine Toyota Accessory
SuperChrome or Aluminum Alloy Wheels,
follow these cleaning guidelines to maintain
the appearance of your wheels:
• If wheels are hot, wait for them to cool
before washing.
• Use a soft sponge or cotton cloth to
apply the same mild car-wash soap as
used for the vehicle body. Quickly rinse
off with water. Use a soft cloth to apply
the same car wax as used for the
vehicle body.
• DO NOT USE: Any kind of chemical-
based cleaners, alcohol, solvents,
gasoline, steam cleaners, scouring
pads, wire brushes or coarse abrasives
to clean your wheels.
