Chevrolet 2007 Express Automobile User Manual


 
Voltmeter Gage
When your engine is not
running, but the ignition
is on (in the RUN
position), this gage
shows your battery’s
state of charge in
DC volts.
When the engine is running, the gage 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.
You can only drive for a short time with the
reading in either warning zone. If you must drive,
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
With the ignition on, the brake system warning light
will come on when you set your parking brake.
The light will stay on if your parking brake doesn’t
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
Your vehicle’s hydraulic brake system is divided
into two parts. If one part isn’t working, the other
part can still work and stop you. For good braking,
though, you need both parts working well.
If the warning light comes on, there could be a
brake problem. Have your brake system inspected
right away.
