Voltmeter Gage; Service Transmission Warning Light - Chevrolet 2007 Kodiak Owner's Manual

Voltmeter Gage

Readings in either warning zone indicate a
possible problem in the electrical system.
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 may not be
able to provide full power at engine idle. As engine
speeds are increased, this condition should
correct itself because higher engine speeds allow
the charging system to create maximum power.

When your engine is
running, the voltmeter
gage shows the
charging system
voltage.
You can only drive a short time on the battery.
Be sure to shut off the radio, the fan or any
unnecessary accessories and have the system
serviced.

Service Transmission Warning Light

If your vehicle has an Allison
transmission, certain transmission malfunctions
will turn this light on.
If this light comes on while you are driving, do not
use the transmission shift control or you may
lose forward gears. The computer for the
transmission senses a problem and chooses a
gear to stay in so that you can drive the vehicle in
that gear. You may not be able to drive as fast
or back up when this light is on.
