The following descriptions are provided to give you a
better understanding of the maintenance services that
should be performed on your vehicle. The scheduled
maintenance log indicates at which time/mileage
intervals each service should be performed. Please note
that many maintenance services should be performed
only by a qualified technician.
Air Conditioner FilterRefer to your Owner’s Manualfor service details.Axle Shaft BootsAt driven wheels, check the axle shaft boots and
clamps for cracks, deterioration and damage. Replace
any damaged parts and, if necessary, repack the grease.
Re-torque the axle shaft flange bolts at the indicated
intervals. A qualified technician should perform these
operations.Ball Joints and Dust CoversCheck the suspension and steering linkage ball joints
for looseness and damage. Check all dust covers for
deterioration and damage. A qualified technician
should perform these inspections.Body InspectionVisually check for corrosion, scratches and other
damage. Check outer body panels, inner panels of the
hood and doors, and underneath the vehicle. Apply
touch-up paint to any chips and scratches or have
them repaired by a qualified technician. For further information on maintenance
services that you can perform yourself, see the
“Service Procedures and Specifications” section

Brake FluidReplace using fluid type specified in your Owner’s
Manual. A qualified technician should perform this
operation.Brake Lines and HosesVisually inspect for proper installation. Check for
chafing, cracks, deterioration and signs of leakage.
Replace any deteriorated or damaged parts. A quali-
fied technician should perform these operations.Brake Linings/Drums and Brake Pads/RotorsCheck the parking brake linings (shoes) and drums
for scoring, burning, fluid leakage, broken parts and
excessive wear. Check brake pads and rotors for exces-
sive wear; check brake rotors for runout. Check brake
calipers for fluid leakage. A qualified technician
should perform these inspections.Charcoal CanisterCheck for internal damage and clogging. If necessary,
clean with compressed air or replace. A qualified tech-
nician should perform these operations.
Dif ferential OilCheck for correct oil level and inspect each differential
component for signs of leakage. If you discover any
leakage, have it repaired by a qualified technician
immediately. Refer to your Owner’s Manualfor fluid
specifications.Drive BeltsInspect for cracks, excessive wear and oiliness. Check
the belt tension and adjust if necessary. Replace the
belts if they are damaged.Engine Air FilterCheck for damage, excessive wear and oiliness.
Replace if necessary.Engine CoolantDrain and flush the cooling system and refill 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 MAINTENANCE

miles. Replace every 60 months/50,000 miles there-
after.Engine Oil and Oil FilterReplace the oil filter and drain and refill the engine oil
at specified intervals. For recommended oil grade and
viscosity, refer to your Owner’s Manual. Some models
are equipped with a replaceable oil filter element and

Refer to your Owner’s Manual.Engine Valve Clearance (except GS 300 and IS)Inspect for excessive lifter noise and engine vibration
and adjust if necessary. A qualified technician should
perform this operation. (The GS 300 and IS are
equipped with hydraulic valve lash adjusters, which
require no periodic clearance inspection or adjustment.)
Exhaust Pipes and MountingsVisually inspect the exhaust pipes, muffler and hang-
ers 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 HosesVisually inspect for corrosion, damage, cracks and
loose or leaking connections. Tighten connections or
replace parts as necessary.Fuel Tank Cap GasketVisually inspect for cracks, deterioration and damage
and replace if necessary.Nuts and Bolts on ChassisRe-tighten the seat mounting bolts and front/rear
