Chevrolet 2010 Express Automobile User Manual


 
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 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.
Brake System Warning Light
The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can still
work and stop the vehicle. For good braking, both need
to work.
If the warning light comes on, there could be a brake
problem. Have the brake system inspected right away.
United States Canada
This light should come on briefly when ignition key is
turned to ON/RUN. If it does not come on, have it fixed
so it will be ready to warn if there is a problem.
