75The indicator lamp does not illuminate
and/or does not remain illuminated with
the weight of a typical 12-month-old child in
a standard child restraint or less on the
front passenger seat.
The system is malfunctioning.
Make sure that there is nothing between seat cush-
ion and child seat and check installation of the child
seat.
Make sure that no objects applying supplemental
weight onto the seat are present.
Make sure that no objects which apply forces to the
seat are present (e.g. objects such as books, brief-
cases etc. lodged behind or around the seat, head
restraints pushing against roof etc.). The system
may recognize such forces as supplemental weight.
If the light remains out, have the system checked as
soon as possible by an authorized Mercedes-Benz
Center. Do not transport a child on the front passen-
ger seat until the system has been repaired.
Also note any messages in the multifunction display
and follow corrective steps (
page 374).
Warning!
G
If the
75
indicator lamp does not
illuminate or remains out with the
weight of a typical 12-month-old child in a
standard child restraint or less on the front
passenger seat, do not transport a child on
the front passenger seat until the system
has been repaired.

Possible cause
Possible solution
Front passenger
airbag activated
See Operator’s Manual
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 passenger 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 following:
Make sure that there is nothing between seat cush-
ion and child seat and check installation of the child
seat.
Make sure that no objects applying supplemental
weight onto the seat are present.
Make sure that no objects which apply forces to the
seat are present (e.g. objects such as books, brief-
cases 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 heavier weight than actually present.

Possible cause
Possible solution
Front passenger
airbag deactivated
See Operator’s Manual
Air bag is deactivated while
driving even though an
adult or someone larger
than a small individual is
occupying the front pas-
senger 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 following:
Do not lean on armrests or lift yourself up using han-
dle over the door.
Adjust the seat in a height position (
page 38).
Make sure that no objects which apply forces to the
seat are present (e.g. objects such as books, brief-
cases etc. lodged underneath, behind 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.
Re-position yourself.
Sit properly belted in a nearly upright position with
your back against the seat backrest.
If performing any of the above corrective steps is
successful, the message
Front passenger airbag
activated
will appear in the multifunction display,
confirming the situation has been remedied.

Flat tire
Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.
Remove the jack.
1-5 Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).
Before storing the jack in the trunk, it
should be fully collapsed.Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).
iWrap the damaged wheel in the protec-
tive film that comes with the spare
wheel and put the wheel in the trunk.
You can also place the damaged wheel
down into the spare wheel well. In this
case, you must stow the holder from
the spare wheel well in the trunk.
Do not activate the tire pressure moni-
toring system until the depressurized
tire is no longer in the vehicle.
