ENGINE AIR FILTER
Replace at specified intervals. When performing inspections, check for damage, excessive wear
and oiliness, and replace if necessary.
ENGINE COOLANT
Drain the cooling system and refill with an ethylene-glycol type coolant. Inspect hoses and
connections for corrosion and leaks. Tighten connections and replace parts when necessary. A
qualified technician should perform these operations. (For further details, refer to
Radiator,
Condenser and Hoses
in the
Vehicle Maintenance and Care
section of the
Owner’s Manual).
NOTE:
Your Toyota is equipped with Genuine Toyota Super Long-Life Coolant. The replacement
intervals for engine coolant recommended in this booklet are based on replacement
with Genuine Toyota Super Long-Life Coolant or similar high-quality non-silicate,
non-amine, non-borate ethylene-glycol coolant with long-life hybrid organic acid
technology (i.e., a combination of low phosphates and organic acids). If another type of
ethylene-glycol coolant is used, replacement intervals may be different.
ENGINE OIL AND 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.
ENGINE VALVE CLEARANCE
Inspect for tappet noise and engine vibration and adjust if necessary. A qualified technician
should perform this operation.
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.
FRONT OR REAR DIFFERENTIAL OIL
Inspect or replace at specified intervals. When performing inspections, check each component
for signs of leakage. If you discover any leakage, have it repaired by a qualified technician
immediately.
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.
