Vehicle status messages in the multifunction display
Warning and malfunction messages
appear in the multifunction display located
in the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 130) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.
Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 117).Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (
page 117). They
are then stored in the vehicle status mes-
sage memory (
page 130). Remember
that clearing a message will only make the
message disappear. Clearing a message
will not correct the condition that caused
the message to appear.
On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may
appear in the multifunction display. High
priority messages appear in red color.
