The Fuel Gauge Does Not Move to Full-position.EKS0030V
1.QUESTION 1
Does it take a long time for the pointer to move to Full-position?
Ye s o r N o
Ye s > > G O T O 2 .
No >> GO TO 3.
2.QUESTION 2
Was the vehicle fueled with the ignition switch ON?
Ye s o r N o
Yes >> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise it will take a long time to move
to Full-position because of the characteristic of the fuel gauge.
No >> GO TO 3.
3.QUESTION 3
Is the floor or the vehicle inclined?
Ye s o r N o
Yes >> It may not be filled fully.
No >> GO TO 4.
4.QUESTION 4
During driving, does the fuel gauge pointer move gradually toward E-position?
Ye s o r N o
Yes >> Check the components. Refer to DI-41, "Electrical Components Inspection" .
No >> The float arm may interfere or bind with any of the components in the fuel tank.
The Fuel Gauge Does Not Work.EKS0030W
1.HARNESS CONNECTOR INSPECTION
1. Turn the ignition switch OFF.
2. Check combination meter, fuel level sensor unit, sub fuel level sensor unit and terminals (meter-side,
module-side, and harness-side) for poor connection and bend.
OK or NG
OK >> GO TO 2.
NG >> Repair connector.
2.CHECK INSTALLATION CONDITION
Check fuel level sensor unit or sub fuel level sensor unit installation (refer toFL-4, "
FUEL LEVEL SENSOR
UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY" for QR engine models or FL-17, "FUEL LEVEL SEN-
SOR UNIT" for YD engine models, and check whether the float arm interferes or binds with any components
inside the arm.
OK or NG
OK >> Fuel level sensor unit is OK.
NG >> Check fuel level sensor unit or sub fuel level sensor unit. Refer to DI-41, "
Electrical Components
Inspection" .

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.

●(1) If valve noise increases, check valve clearance.
●(2) Never use CG-4 oil.
●(3) Oil filter element assembly and O-ring seal are replacement parts.
●(4) First replace at 100,000 Km (60,000 miles)/60 months, then every 60,000Km (36,000 miles)/36 months. After first
replacement, perform "I" (checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of
