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
