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 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.

Undervoltage
Switch off
consumers
The battery has insufficient voltage.

Turn off unnecessary electrical con-
sumers.
Visit workshop
The battery is no longer charging.
Possible causes:

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake system re-
quires electrical energy and may be oper-
ating with restricted capability.
Considerably greater brake pedal force is
required and the stopping distance is in-
creased.

Stop immediately and check the
poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise
the engine will overheat due to an in-
operative water pump which may re-
sult in damage to the engine. Notify
an authorized Mercedes-Benz Center.
If it is intact:

Drive immediately to the nearest au-
thorized Mercedes-Benz Center. Ad-
just driving to be consistent with
reduced braking responsiveness.
