DIC Warnings and Messages
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. Multiple messages may
appear one after another.
Some messages may not require immediate
action, but you can press any of the DIC buttons
on the instrument panel or the trip odometer
reset stem on the instrument panel cluster
to acknowledge that you received the messages
and to clear them from the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These
messages require action before they can be
cleared. You should take any messages that
appear on the display seriously and remember that
clearing the messages will only make the
messages disappear, not correct the problem.The following are the possible messages that can
be displayed and some information about them.

every oil change. It will not reset itself. To reset
the Engine Oil Life System, do the following:
