Vehicle 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 the set/reset button
to acknowledge that you received
the message and clear it from the
DIC display. Pressing any of the
DIC buttons also acknowledges and
clears any messages. 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.
