CHEVROLET 2009 Silverado - Manual (Page 30)

Tachometer
When the gas engine is off and the key is in the
ON/RUN position, the position of the tachometer
indicator shows the state of the vehicle:
• AUTO STOP position indicates that the vehicle is
still able to move and the engine could restart, by
an Auto Start, at any time.
• OFF position indicates that the engine is off.
When the engine is on, the tachometer indicator shows
the engine’s revolutions per minute (rpm).
Charging System Light
This light will come
on briefly when the
ignition is turned to
ACC/ACCESSORY or
ON/RUN, but the engine
is not running, as a check
to show it is working.
It should go out once the engine has been started. If it
stays on, or comes on while driving, there could be a
problem with the charging system. A charging system
Driver Information Center (DIC) message may also
appear. See DIC Warnings and Messages on page 3-12
for more information. This light could indicate that there
are electrical problems. Have it checked right away. If a
short distance must be driven with the light on, be certain
to turn off all the accessories, such as the radio and air
conditioner.
