GMC 2008 Canyon - Manual (Page 162)

Charging System Light
This light will come on
briefly when you turn on the
ignition, but the engine is
not running, as a check to
show you it is working.
It should go out once the engine is running. If it stays on,
or comes on while you are driving, you may have a
problem with the charging system. A charging system
Driver Information Center (DIC) message may also
appear. See DIC Warnings and Messages on page 3-42
for more information. This light could indicate that you
have problems with a generator drive belt, or another
electrical problem. Have it checked right away. If you
must drive a short distance with the light on, be certain
to turn off all your accessories, such as the radio and air
conditioner.
Up-Shift Light
Your vehicle may have an
up-shift light.
When this light comes on, you should shift to the next
higher gear if weather, road, and traffic conditions allow
you to.
