MAINTAINING YOUR WARRANTY

IMP OR TA N T 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.
Toyo t a 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. Toyo t a will
not deny a warranty claim solely because
you used a service provider other than a
Toyo t a 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 Toyo t a
warranty coverages, see the Warranty
Information portion of this booklet.

MAINTENANCE
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
specic oil viscosity rating recommended
for your vehicle/engine type.
Additional Maintenance
In addition to scheduled maintenance,
your Toyo t a requires ongoing general
maintenance, such as uid 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 Toyo t a 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 c a r-wa sh soap as
used for the vehicle body. Quickly rinse
off with wa t er. 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.
