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.
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 Toyota 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 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.
