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 driveshaft 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 ethylene-glycol 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 of necessary. A qualified technician should perform these operations. 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 acid). 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 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 seat-mounting bolts and front/rear suspension member retaining bolts to specified torque.

Radiator Core and Condenser

Steering Gear Box

Inspect for signs of leakage. If you discover any leakage, have it repaired immediately by a qualified technician.

Steering Linkage and Boots

Tire Rotation

Tires should be rotated at specified intervals according to the instructions in the Owner's Manual. When rotating tires, check for damage and uneven wear. Replace if necessary.
