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
specific oil viscosity rating recommended
for your vehicle/engine type.
Flex Fuel Vehicles (Use of E85)
When using E85 fuel, your engine oil and oil
filter may need to be replaced more often.
If using E85 fuel more than 50% of the time,
change the engine oil and oil filter every
2,500 miles or three months. If using E85 fuel
less than 50% of the time, follow the normal
engine oil and oil filter change schedule
(5,000 miles or six months).
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.

guidelines to maintain the appearance of
your wheels:
