Explanation of Maintenance Items
37
Differential Oil
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.
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.
Selected models also require periodic inspection of the drive shaft bolt for proper
torque. 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 Coolant
Drain and flush the cooling system and refill with an ethyleneglycol type
coolant. Inspect the radiator, condenser and/or intercooler for leaves, dirt and
insects and clean if necessary. Inspect hoses and connections for corrosion and
leaks. Tighten connections and replace parts as 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:YourToyota is equipped with Genuine Toyota Super LongLife Coolant. The
replacementintervals 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, replacementintervals 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.

Explanation of Maintenance Items

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.
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 and Body
Retighten the seatmounting bolts and front/rear suspension member retaining
bolts to specified torque.
Propeller Shaft
Lubricate the propeller shaft spiders and slide yokes with lithiumbase chassis grease
and the double cardan joint with molybdenumdisulfide lithiumbase chassis grease,
and retorque the bolt. Only a qualified technician should retorque the bolt.
Radiator Core and Condenser
Inspect for debris and signs of damage. Have any problem repaired immediately
by a qualified technician.
Spark Plugs
Replace at specified intervals. Install new plugs of the same type as originally
equipped. A qualified technician should perform this operation.
Steering Gear Box
Inspect for signs of leakage. If you discover any leakage, have it repaired imme
