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-21, "Electrical Components Inspection" .
No >> The float arm may interfere or bind with any of the components in the fuel tank.
