Engine Coolant Temperature Gauge; Voltmeter Gauge - GMC Acadia 2011 Owner's Manual

5-14 Instruments and Controls
Here are some situations that may
occur with the fuel gauge. None of
these indicate a problem with the
fuel gauge.
At the gas station, the fuel pump
shuts off before the gauge
reads full.
It takes a little more or less fuel
to fill up than the fuel gauge
indicated. For example, the
gauge may have 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 goes back to empty
when the ignition is turned off.
Engine Coolant
Temperature Gauge
Metric
This gauge shows the engine
coolant temperature. Under normal
driving conditions the gauge will
read approximately 100 °C (210°F)
or less. If the gauge pointer is near
125 °C (260°F), the engine is
too hot.
It means that the engine coolant
has overheated. If the vehicle has
been operating under normal driving
conditions, pull off the road, stop the
vehicle and turn off the engine as
soon as possible.
See Engine Overheating on
page 10 20 for more information.

Voltmeter Gauge

When the engine is not running, but
English
the ignition is turned on, this gauge
shows the battery's state of charge
in DC volts.
When the engine is running, this
gauge shows the condition of the
charging system. The vehicle's
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may fluctuate.
This is normal. Readings between
the low and high warning zones
indicate the normal operating range.
