Refer to MA-7, "
Periodic Maintenance" .
Caution label is fixed inside the glove box.
REPLACEMENT AND PROCEDURES
1. Remove the glove box.
2. Remove the ventilation air filter cover.
3. Take out the ventilation air filter from blower unit.
4. Replace with new one and reinstall on blower unit.
5. Reinstall the glove box.
CLEANING
1. Soak the filter in a solution of a mild strength detergent cleaner
& water.
2. Move the filter lightly through the solution to clean.
3. Rinse with tap water.
4. Drain the filter water into a can etc., and dry.

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.
