OFF before the pointer reaches
"Fit
on the gauge
dial. Failure to do so may damage the fuel gauge.
NOTE: The fuel gauge is a bobbin (cross-coil) type,
hence the fuel level is continuously indicated even
when the ignition switch is OFF, and the pointer
moves more slowly than that of
a
bimetal type.
• If the pointer of the fuel gauge does not move at
all, replace the gauge.
• If the gauge is OK, inspect the fuel gauge send-
ing unit.
