416 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 173) 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 158) or
buttonj,k,ÿ, orè on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using the reset button (page 158) or
buttonj,k,ÿ, orè on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 173). Remember that

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

cause/consequence
Possible solution
Front passenger airbag
enabled
see Operator’s Manual
Front passenger front
air bag is activated
while driving even
though a child, small
individual, or object
below the system’s
weight threshold is on
the front passenger
seat, or the front pas-
senger seat is empty.
Objects on the seat or
forces acting on the
seat may make the
system sense supple-
mental weight.
Stop the vehicle in a safe location as soon as possible and check the front passen-
ger seat for the following:
Turn off the ignition (
page 38).

Remove child and child restraint from front passenger seat and properly secure
the child in rear seat employing the child restraint if necessary.

Remove any other items from on and around the front passenger seat and
make sure the storage bag on the back of the front passenger seat is empty.

Make sure that no objects which apply forces to the seat are present (e.g. ob-
jects such as books, briefcases etc. lodged behind or around the seat, head re-
straints pushing against roof etc.). The system may recognize such forces as
supplemental weight and sense that an occupant on the front passenger seat
is of a heavier weight than actually present.

Keep the seat unoccupied, close the front passenger door and turn on the igni-
tion (
page 38).
