Buick 2005 Century - Manual (Page 143)

Here are four things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage:
• At the gas station, the pump shuts off before the
gage reads full.
• It takes more, or less, fuel to fill up than the gage
reads. For example, the gage reads half full, but
it took more, or less, than half of the tank’s capacity
to fill it.
• The gage pointer may move while cornering,
braking or accelerating.
• The gage may not indicate empty when the ignition
is turned off.
Low Fuel Warning Light
If the vehicle’s fuel is low, a light on the instrument
panel cluster will come on and a chime will sound
periodically until fuel is added to the fuel tank.
It will also come on for a few seconds when the ignition
is turned on as a check to indicate it is working. If it
does not come on then, have it fixed.
