DIC Warnings and Messages
Warning messages are displayed on the Driver

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 any of the four DIC buttons located on
the steering wheel or the trip odometer reset stem
located on the instrument panel cluster to acknowledge
that you received the messages and clear them from
the display. Some messages cannot be cleared from the
display because they are more urgent. These messagesrequire action before they can be removed from the DIC
display. 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.

message will appear on the DIC. Driving with this
problem could drain your battery. Have the electrical
system checked as soon as possible. Pressing any of
the four DIC buttons or the trip odometer reset stem will
clear the message from the DIC display.

be changed. See “Engine Oil Life System” underDIC
Operation and Displays on page 3-44andEngine
Oil Life System on page 5-16for information on how to
