368 Practical hintsWhat to do if …Vehicle status messages in the multifunction display
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 132) 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
steering wheel.
Other high-priority messages and messag-
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 steering
wheel. They are then stored in the vehicle
status message memory (
page 132). Re-
member that clearing a message will only
make the message disappear. Clearing a
message will not correct the condition that
caused the message to appear.
