CHANGE ENGINE OIL
This message is displayed when the engine oil needs to
be changed. When you change the engine oil, be
sure to reset the CHANGE ENGINE OIL message. See
Engine Oil Life System on page 5-17 for information
on how to reset the message. This message will clear
itself after 10 seconds until the next ignition cycle or until
the message is reset. See Engine Oil on page 5-14
and Scheduled Maintenance on page 6-4 for more
information.
CHARGING SYSTEM FAILURE
On some vehicles, if there is a problem with the
generator and battery charging system, this message
will appear on the DIC, a chime will sound, and the
charging system light on the instrument panel cluster will
come on. Driving with this problem could drain your
battery. Turn off all unnecessary accessories. Stop and
turn off the vehicle as soon as it is safe to do so.
Have the electrical system checked by your GM dealer
immediately. See Charging System Light on page 3-34
and Voltmeter Gage on page 3-34 for more information.
CHECK OIL LEVEL
If the oil level in the vehicle is low, this message will
appear on the DIC. Check the oil level and correct it as
necessary. You may need to let the vehicle cool or
warm up and cycle the ignition to be sure this message
will clear. Once the problem is corrected, pressing
any of the four DIC buttons or the trip odometer reset
stem will acknowledge the message and clear it from the
DIC display. This message will clear itself after
10 seconds, until the next ignition cycle. See Engine Oil
on page 5-14 for additional information.
CHECK TIRE PRESSURE
If your vehicle has the tire pressure monitor system and
a low tire pressure is detected in any of the vehicle's
tires, this message will appear on the DIC. Pressing any
of the four DIC buttons or the trip odometer reset
stem will acknowledge the message and clear it from
the DIC display. It will appear at each ignition cycle until
the tires are inflated to the correct inflation pressure.
