fuel tank capacity BUICK LUCERNE 2010 Owner's Manual

Fuel Gauge
United StatesCanada
The fuel gauge shows about how much fuel is in
the tank.
An arrow on the fuel gauge indicates the side of the
vehicle the fuel door is on. The gauge works only when the ignition is on. When the
indicator moves to the edge of the low fuel warning
band, the low fuel warning light comes on and a chime
sounds. The vehicle still has a little fuel left, but the
vehicles fuel tank should be filled soon.
Here are some things that some owners ask about.
None of these show a problem with the fuel gauge:
.At the service station, the gas pump shuts off
before the gauge reads full.
.It takes more (or less) fuel to fill up than the gauge
indicated. For example, the gauge may have
indicated half full, but it took more (or less) than
half the tank's capacity to fill it.
.The gauge moves up a little while turning a corner,
speeding up or making a hard stop.
.The gauge does not go back to empty when the
ignition is turned off.
