Periodic MaintenanceBLS0008Z
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
(Annual Mileage <30,000 Km [18,000 miles]/year)
QR and VQ ENGINE
Abbreviations: I = Inspect and correct or replace as necessary, R = Replace
[ ] = At the specified distance only
NOTE:

(1) Periodic maintenance is not required. However, if valve noise increases, check valve clearance.

(2) Replace the drive belt if found damaged or if the auto tensioner reading (for QR20DE engine) reaches the maximum
limit.

(3) First replace at 100,000 km (60,000 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.

Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”. MAINTENANCE OPERATIONMAINTENANCE INTERVAL Reference page

PERIODIC MAINTENANCE

MAINTENANCE UNDER SEVERE DRIVING CONDITIONS
(Annual Mileage <30,000 Km [18,000 miles]/year)
The maintenance intervals shown on the preceding pages are for normal operating conditions. If the vehicle is
mainly operated under severe driving conditions as shown below, more frequent maintenance must be per-
formed on the following items as shown in the table.
Severe driving conditions
A — Driving in dusty conditions
B — Repeatedly driving short distances
C — Towing a trailer or caravan
D — Extensive idling
E — Driving in extremely adverse weather conditions or in areas where ambient temperatures are either
extremely low or extremely high
F — Driving in high humidity or mountainous areas
G — Driving in areas using salt or other corrosive materials
H — Driving on rough and/or muddy roads or in the desert
I — Driving with frequent use of braking or in mountainous areas
J — For models without EURO-OBD system
