Voltmeter Gauge; Seat Belt Reminders - GMC Chevrolet Express 2022 Owner's Manual

This gauge shows the engine coolant
temperature.
The warning area at the far end of the
gauge may appear shaded or may be
colored red.
If the pointer approaches the warning area,
or the shaded thermostat symbol the engine
may be too hot.
Under some driving conditions, including
those listed below, it is normal for the
temperature to rise above the usual
operating range and approach the far end of
the gauge:
Stop and go driving in heavy traffic.
High speed operation in warm weather.
Uphill driving.
Trailer towing or hauling a heavy load.
It is normal for the reading to fluctuate.
If the gauge pointer reaches the warning
area or the shaded thermostat symbol at
the far end of the gauge and remains there
for more than 30 seconds, the engine
coolant has overheated.
If the engine coolant has overheated, pull
over and stop the vehicle as soon as it is
safe to do so. Then, turn the engine off
immediately.
See Engine Overheating 0 176.

Voltmeter Gauge

When the engine is not running, but the
ignition is on, this gauge shows the
battery's state of charge in DC volts.
When the engine is running, the gauge
shows the condition of the charging system.
Readings between the low and high warning
zones indicate the normal operating range.
Readings in the low warning zone may occur
when a large number of electrical
accessories are operating in the vehicle and
the engine is left at an idle for an extended
period. This condition is normal since the
charging system is not able to provide full
Instruments and Controls
power at engine idle. As engine speeds are
increased, this condition should correct itself
as higher engine speeds allow the charging
system to create maximum power.
The vehicle can be only driven for a short
time with the reading in either warning
zone. If it must be driven, turn off all
unnecessary accessories.
Readings in either warning zone indicate a
possible problem in the electrical system.
Have the vehicle serviced as soon as
possible.

Seat Belt Reminders

Driver Seat Belt Reminder Light
There is a seat belt reminder light on the
instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to remind
the driver to fasten their seat belt. Then the
light stays on solid until the belt is buckled.
