EXPLANATION OF MAINTENANCE ITEMS
Engine Oil and Oil Filter
Replace the oil filter and drain and refill
the engine oil at specified intervals. For
recommended oil grade and viscosity,
refer to the Owner’s Manual.
NOTE: Your vehicle is certified with
Genuine Toyota 0W-20 motor oil. For
VEHICLES CERTIFIED FOR 0W-20 motor
oil, the oil change interval is 10,000 miles
or 12 months IF 0W-20 MOTOR OIL IS
BEING USED. If 0W-20 is not available,
5W-20 mineral oil may be used. However,
it must be replaced at a 5,000-mile or
six-month INTERVAL with 0W-20 motor oil.
For customers who primarily drive their
vehicle under any of the listed Special
Operating Conditions, the motor oil and
filter should be replaced at 5,000 miles or
six months, REGARDLESS OF THE OIL USED
(OR CERTIFICATION OF THE VEHICLE).
Engine Oil Cooler and Hoses
Visually inspect for corrosion, damage,
cracks and loose or leaking connections.
Tighten connections or replace parts
as necessary.
Exhaust Pipes and Mountings
Visually inspect the exhaust pipes, muffler
and hangers for cracks, deterioration and
damage. Start the engine and listen
carefully for any exhaust gas leakage.
Tighten connections or replace parts
as necessary.
Fuel Lines and Connections,
Fuel Tank Band and Fuel Tank
Vapor Vent System Hoses
Visually inspect for corrosion, damage,
cracks, and loose or leaking connections.
Tighten connections or replace parts
as necessary.
Fuel Tank Cap Gasket
Visually inspect for cracks, deterioration
and damage and replace if necessary.
Nuts and Bolts on Chassis
