The yellow engine mal-
function indicator lamp
comes on while driving.
There may be a malfunction in the

fuel management system


ignition system (gasoline engine)


emission control system


systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode.

Have the vehicle checked as soon as possi-
ble by an authorized Mercedes-Benz Center.
An on-board diagnostic connector is used
by the service station to link the vehicle to
the shop diagnostics system. It allows the
accurate identification of system malfunc-
tions through the readout of diagnostic trou-
ble codes. It is located in the front left area
of the footwell next to the parking brake.

Some states may by law require you to visit
a workshop immediately as soon as the engine
malfunction indicator lamp comes on. Check lo-
cal requirements.

What to do if …
On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may ap-
pear in the multifunction display.
For your convenience the messages are di-
vided into two sections:

Text messages (
page 398)


Symbol messages (
page 411)
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, warning/
indicator lamps, malfunction/warning mes-
sages or the failure of any systems. Driving
characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Visit an authorized
Mercedes-Benz Center as soon as possible.i
Switching on the ignition causes all instru-
ment cluster lamps (except low beam headlamp
indicator lamp, high beam headlamp indicator
lamp, and turn signal indicator lamps unless ac-
tivated) as well as the multifunction display to
come on. Make sure the lamps and multifunction
display are in working order before starting your
journey.

Possible cause/consequence
Possible solution
(USA only)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 passen-
ger seat, or the front passenger
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 passenger seat for the following:
Apply the parking brake.

Switch off the ignition (
page 38).

Open the front passenger door.

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 pocket on the back of the front pas-
senger seat is empty.

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 turn
on the ignition (
page 38).

quence
Possible solutionMonitor the 75 indicator lamp on the center console (
page 29) and
the multifunction display in the instrument cluster (
page 26) for the following:
With the seat unoccupied and the ignition turned on,


the 75 indicator lamp on the center console should illuminate and
remain illuminated, indicating that the OCS (
page 80) has deactivated the
front passenger front air bag.


the message
Front passenger airbag enabled See Operator’s Manual
or the
message
Front passenger airbag disabled See Operator’s 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 display.
If above conditions are met, you can occupy the front passenger seat again. De-
pending on the front passenger classification sensed by the OCS (
page 80), the
75 indicator lamp will remain illuminated or go out.
If above conditions are not met, the system is not working properly. Have the sys-
tem checked as soon as possible by an authorized Mercedes-Benz Center.
Warning!
G
If the 75indicator lamp
remains out even after performing the above
corrective steps, do not have any children
12 years old and under and
other small individuals use the front passen-
ger seat until the system has been repaired.

(USA only)Front passenger
airbag disabled
See Operator’s 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:
Apply the parking brake.

Switch off the ignition (
page 38).

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

Adjust the seat in a height position (
page 43).

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

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