Warning and malfunction messages ap-
pear 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 126) 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 buttonJ (
page 24) or
buttonj, k, ·, orè on the
stering wheel.

es of less immediate priority (regular dis-
play colors) can be cleared from the
multifunction display using the reset
buttonJ (
page 24) or buttonj,
k, ·, orè on the stering wheel.
They are then stored in the vehicle status

the message disappear. Clearing a mes-
sage will not correct the condition that
caused the message to appear.
