Front passenger
airbag activated
see Oper.’s Man.
Front passenger front air
bag is activated while driv-
ing 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.

Front passenger
airbag activated

If performing any of the above corrective steps is suc-
cessful, the message
Front passenger airbag deacti-
vated
will appear in the multifunction display,
confirming the situation has been remedied. Note that
after performing the corrective steps, it may take up to
60 seconds for the message
Front passenger airbag
deactivated
to appear.
If the message
Front passenger airbag activated

remains on in the multifunction display and/or the
75indicator lamp remains out even after
performing the above corrective steps, have the system
checked as soon as possible by an authorized
Mercedes-Benz Center.
Do not have any children12 years old and under and
other small individuals use the front passenger seat un-
til the system has been repaired.
Warning!

Possible solution
Front passenger
airbag deactivated
see Oper.’s Man.
Front passenger front 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 39).

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 was charged with a battery
charger or jump started.

Have the battery checked at a service
station.
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
authorized Mercedes-Benz Center.
Adjust driving to be consistent with
reduced braking responsiveness.

Battery/Alternator
Stop vehicle
The battery is malfunctioning.
The SBC brake system requires electrical
energy and therefore has only limited op-
eration. Considerably greater brake pedal
force is required and the stopping dis-
tance is increased.

Stop the vehicle as soon as it is safe
to do so. Adjust driving to be consis-
tent with reduced braking responsive-
ness.

Notify an authorized Mercedes-Benz
Center.
Low voltage
Start engine
The battery has insufficient voltage.

Start the engine (
page 47).
Malfunction
Electrical consumers
switched off
The consumer battery has insufficient
voltage and can no longer supply the con-
venience functions such as seat ventila-
tion*.
The electrical consumers will come back
online as soon as on-board voltage is suf-
ficient.

Brake wear
Visit workshop
The brake pads have reached their wear
limit.

Brake pad thickness must be visually
inspected at the intervals specified in
the Maintenance Booklet.

Have the brake pads replaced as soon
as possible.
T
Reduced braking power
Depress brake
pedal fully
The SBC brake system is in emergency
operation mode. Considerably greater
brake pedal force is required and the
stopping distance is increased.
The maximum speed is limited to 55 mph
(90 km / h).

Do not drive any further.

Stop the vehicle and notify an autho-
rized Mercedes-Benz Center.

Significantly greater force must be ap-
plied to the brake pedal.

Reduced braking power

Start engine
The battery has insufficient voltage and
cannot supply sufficient power to the
SBC brake system.

Start the engine.
The message disappears when suffi-
cient voltage is available.
!Brake pad thickness must be visually
inspected by a qualified technician at
the intervals specified in the
Maintenance Booklet.
