Fuel Gauge - Buick 2014 LaCrosse Owner's Manual

5-12 Instruments and Controls
When the engine is on, the
tachometer will indicate the engine s
revolutions per minute (rpm). The
tachometer may vary by several
hundred rpm s, during auto stop
mode, when the engine is shutting
off and restarting.
A slight bump may be felt when the
transmission is determining the
most fuel efficient operating range.

Fuel Gauge

Metric
English
When the ignition is on, the fuel
gauge indicates about how much
fuel is left in the tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There is still
a little fuel left, but the fuel tank
should be filled soon.
Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
At the service station, the fuel
pump shuts off before the gauge
reads full.
It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge indicated the tank was
half full, but it actually took a
little more or less than half the
tank's capacity to fill the tank.
The gauge moves a little while
turning a corner or speeding up.
The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.
