358 Practical hintsWhat to do if …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 138) 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 127) or
buttonj, k, ÿ, orè on the
steering wheel.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (page 127) or
buttonj, k, ÿ, orè on the
steering wheel. They are then stored in the
vehicle status message memory
(

message will only make the message
disappear. Clearing a message will not
correct the condition that caused the
message to appear.
