follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 151) 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 140) or but-
ton k,j, è, orÿ 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 140) or but-
ton k,j, è, orÿ on the
steering wheel. They are then stored in the
vehicle status message memory
(

message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.

taken note of and, where a malfunction is
indicated, addressed as soon as possible at
