Periodic MaintenanceELS000AM
The following tables show the normal maintenance schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
ENGINE AND EMISSION CONTROL MAINTENANCE (QR20DE AND QR25DE PETROL ENGINE)
(Annual Mileage <30,000 Km/year)
Abbreviations: I = Inspect and correct or replace as necessary,R = Replace,.
NOTE:
● Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.
●(1)Periodic maintenance is not required. However, if valve noise increases, check valve clearance.
●(2) Replace the drive belts if found damaged or if the auto belt tensioner reading reaches the maximum limit.
●(3) First replace at 90,000 Km (54,000 miles)/60 months, then every 60,000 km (36,000 miles)/48 months. Perform "I"
(Checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.
●(4) Fuel filter is maintenance-free. For service procedures, refer to FL section.
●(5) Perform only according to "Maintenance Under Severe Driving conditions" for models without Euro-OBD system. For
models with Euro-OBD system, periodic maintenance is not required.
