IMPORTANT MAINTENANCE
INFORMATION
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.

R
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):

USING THE MAINTENANCE LOG CHARTS
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.
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.
D

O NOT USE: Any kind of chemical-
based cleaners, alcohol, solvents,
gasoline, steam cleaners, scouring
pads, wire brushes or coarse abrasives
to clean your wheels.
