See
Oper. Manual
Distronic* is deactivated because the
functionality is impaired by external in-

Distronic* is deactivated because the
Distronic* sensor has not sensed any
other vehicles or objects, e.g. road

Front passenger
airbag
enabled
See Oper. Manual
The 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 passenger seat for the following:
Switch off the ignition (
page 39).
Remove child and child restraint from passenger seat and
properly secure the child in rear seat employing the child
restraint if necessary.
Make sure that no objects which applying supplemental
weight onto the seat are present. The system may recog-
nize such supplemental weight and sense that an occu-
pant on the passenger seat is of a greater weight than
actually present.
Keep the seat unoccupied, close the passenger door and
switch on the ignition (
page 39).
Monitor the 5/indicator lamp between the center air
vents and the multifunction display in the instrument cluster

With the seat unoccupied and the ignition switched on,
the 5/indicator lamp between the center air

that the OCS (
page 72) 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 last
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 passenger
seat again. Depending on the passenger classification
sensed by the OCS (
page 72), the 5/indicator
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 5/ indicator lamp remains
out even after performing the above correc-
tive steps, do not have any children 12 years
old and under and other small individuals
use the passenger seat until the system has
been repaired.
