Explanation of Maintenance Items
Scheduled Maintenance Logs21
Drive Belts
Inspect for cracks, excessive wear and oiliness. Check the belt tension and
adjust if necessary. Replace the belts if they are damaged.
Drive Shaft Boots
Check the drive shaft boots and clamps for cracks, deterioration and damage.
Replace any deteriorated or damaged parts and, if necessary, repack the grease.
A qualified technician should perform these operations.
Engine Air Filter
Replace at specified intervals. When performing inspections, check for damage,
excessive wear and oiliness, and replace if necessary.
Engine and Inverter Coolant
Drain and flush the cooling system and refill with an ethyleneglycol type
coolant. Inspect hoses and connections for corrosion and leaks. Tighten connec
tions and replace parts as necessary. A qualified technician should perform these
operations.
Note:Your Toyota is equipped with Genuine Toyota Super LongLife Coolant. The
replacement intervals for engine coolant recommended in this booklet are based
on replacement with Genuine Toyota Super LongLife Coolant or similar high
quality nonsilicate, nonamine, nonborate ethyleneglycol coolant with
longlife hybrid organic acid technology (i.e., a combination of low phosphates
and organic acids). If another type of ethyleneglycol coolant is used, replace
ment intervals may be different.
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.
Engine Valve Clearance
Inspect for excessive lifter 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.
