DIC Warnings and Messages
Warning messages are displayed on the DIC to notify
the driver that the status of the vehicle has changed and
that some action may be needed by the driver to correct
the condition. If there is more than one message that
needs to be displayed they will appear one after another.
Some messages may not require immediate action but
you should press the select button to acknowledge that
you received the message and clear it from the display.
Some messages cannot be cleared from the display
because they are more urgent. These message required
action before they can be removed from the DIC display.
The following are the possible messages that can be
displayed and some information about them.
CHANGE ENGINE OIL
This message is displayed when the engine oil needs to
be changed. See “GM Oil Life System” previously in
this section for information on how to reset the message.
OIL LIFE RESET
This message will appear on the display for about
10 seconds after resetting the change engine oil message.
LOW COOLANT LEVEL
If the engine coolant level is low, this message will appear
on the DIC. Adding coolant will clear the message.
ENGINE COOLANT HOT
If the cooling system temperature gets hot, this message
will appear in the DIC. Stop the vehicle and let the
engine idle in PARK (P) to allow the coolant to reach
a safe temperature. This message will clear when the
coolant temperature drops to a safe operating
temperature.
ENGINE OVERHEATED
If the engine cooling system reaches unsafe
temperatures for operation, this message will appear in
the DIC and you will hear a chime. Stop and turn off
the vehicle as soon as it is safe to do so to avoid severe
damage. This message will clear when the engine has
cooled to a safe operating temperature.
OIL PRESSURE LOW
If low oil pressure levels occur, this message will be
displayed on the DIC and a chime will sound. Stop the
vehicle as soon as safely possible and do not operate it
until the cause of the low oil pressure has been
corrected. Check your oil as soon as possible and
have your vehicle serviced.
