642 Practical hintsWhat to do if …?Vehicle status messages in the multi-function 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.
High-priority messages are shown in red
on the multifunction display. Messages of
lower priority are also shown in yellow or
white.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.Certain messages of high priority cannot
be cleared from the multifunction display
using# or L on the multifunction
steering wheel (
page 288).
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using# or L. They are then stored
in the vehicle status message memory
(
page 304). Remember that clearing a
message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.
Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.

Front Passenger
Airbag Disabled
See Oper. Manual
Front passenger front air bag is
deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Engage the electronic parking brake (
page 422).

Switch off the ignition (
page 370).

Have the front passenger vacate the seat and exit the vehicle.

Adjust the seat in a height position (
page 373).

Make sure that no objects which apply forces to the seat are present (e.g.
objects such as books, briefcases etc. lodged underneath, behind or
around the seat). Such forces may cause the system to sense that an oc-
cupant of a lesser weight than actually present is on the front passenger
seat.

Keep the seat unoccupied, close the front passenger door and switch on
the ignition (
page 370).
Monitor the 59indicator lamp right of the instrument cluster
(
page 51) and the multifunction display in the instrument cluster
(page 287) for the following:

Front Passenger
Airbag Disabled
See Oper. Manual
With the seat unoccupied and the ignition switched on (
page 370),


the 59indicator lamp right of the instrument cluster should
illuminate and remain illuminated, indicating that the OCS (
page 47)
has deactivated the air bag.


the message “Front Passenger Airbag Enabled See Oper. Manual” or the
message “Front Passenger Airbag Disabled See Oper. Manual” should not
appear in the multifunction display at any time the seat is unoccupied.
Wait at least 60 seconds for the system to complete the necessary check
cycles and to make sure neither message appears in the multifunction dis-
play.
If above conditions are met, you can occupy the front passenger seat again.
Depending on the front passenger classification sensed by the OCS
(
page 47), the59indicator lamp will remain illuminated or go
out.
If above conditions are not met, the system is not working properly. Have the
system checked as soon as possible by an authorized Mercedes-Benz Center.
Warning!
G
If the 59indicator lamp re-
mains illuminated with an adult occupant on
the front passenger seat even after
performing the above corrective steps, do
not have any passenger use the front pas-
senger seat until the system has been re-
paired.

Possible solution
Front Passenger
Airbag Enabled
See Oper. 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 supplemental weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Engage the electronic parking brake (
page 422).

Switch off the ignition (
page 370).

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 emp-
ty.

Make sure that no objects which apply forces to the seat are present (e.g.
objects such as books, briefcases etc. lodged behind or around the seat,
head restraints 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 greater weight than actually present.

Keep the seat unoccupied, close the front passenger door and switch on
the ignition (
page 370).
Monitor the 59indicator lamp right of the instrument cluster
(
page 51) and the multifunction display in the instrument cluster
