Front passenger
airbag
activated
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:
Switch off the ignition (
page 36).
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 36).

With the seat unoccupied and the ignition turned on,
the 75 indicator lamp on the center console should illuminate and

pied. 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 front passenger seat again. De-
pending on the front passenger classification sensed by the OCS (
page 81), 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
75
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 front passenger seat until the sys-
tem has been repaired.

Possible solution
Front passenger
airbag
deactivated
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:
Switch off the ignition (
page 36).
Have the front passenger vacate the seat and exit the vehicle.
Adjust the seat in a height position (
page 41).
Make sure that no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc. lodged under-
neath, behind or around the seat). Such forces may cause the sys-
tem 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 36).

Low voltage
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 in a safe location or
as soon as it is safe to do so 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 electrohydraulic brake system re-
quires electrical energy and therefore has
only limited operation. Considerably
greater brake pedal force is required and
the stopping distance is increased.
Stop the vehicle in a safe location as
soon as it is safe to do so. Adjust driv-
ing to be consistent with reduced
braking responsiveness.
Notify an authorized Mercedes-Benz
Center.
Low voltage
Start engine
The battery has insufficient voltage.
Start the engine (

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.

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.

Reduced braking power
Depress brake
pedal fully
The electrohydraulic brake system is in
emergency operation mode. Consider-
ably 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 in a safe location as
soon as it is safe to do so and notify
an authorized Mercedes-Benz Center.
Prevent the vehicle from rolling away
by blocking the wheels with wheel
chocks or other sizable objects.
Call for Roadside Assistance.

Reduced braking power
Start engine
The battery has insufficient voltage and
cannot supply sufficient power to the
electrohydraulic 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

able brake pedal force is required and the
stopping distance is increased.
Continue driving with added caution.
Adjust driving to be consistent with
reduced braking responsiveness.
Visit an authorized Mercedes-Benz

Service brake
Visit workshop
There are malfunctions, but the electro-
hydraulic brake system is operating nor-
mally.
Visit an authorized Mercedes-Benz
Center as soon as possible.
Brake overheated
Drive on, but with
even greater care
The brake system is overheated due to an
excessive load on the brakes.
Relieve the load on the brake system.
Drive more smoothly and think ahead
to avoid unnecessary braking.
When driving down slopes, shift into a
lower gear to use the engine’s braking
power (
page 191).
Cautiously continue driving so that
the air stream will cool down the
brakes.

You are driving with the parking brake
set.

Brake fluid
Visit workshop
There is insufficient brake fluid in the
reservoir.
Risk of accident! Stop the vehicle in a
safe location as soon as it is safe to do
so and notify an authorized
Mercedes-Benz Center. Do not add
brake fluid! This will not solve the
problem.

displayed can result in an
accident. Have your brake system checked
immediately.
If there is a malfunction in the electrohy-
draulic brake system, we recommend that
the vehicle be transported with all wheels
off the ground using flatbed or appropriate
wheel lift/dolly equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
u p t o 3 0 m i l e s ( 5 0 k m ) a n d a t a s p e e d n o t t o
exceed 30 mph (50 km/h). For more infor-
mation, refer to “Towing the vehicle”
(page 458).
If the electrohydraulic brake system enters
its emergency operation mode, the driver
must apply significantly greater brake pedal
pressure and depress the pedal much fur-
ther than normal to obtain braking effect. If
necessary, apply full pressure to the brake
pedal. Brakes may only be applied to the
front wheels. Stopping distance is in-
creased!
Do not add brake fluid before checking the
brake system. Overfilling the brake fluid res-
ervoir can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You can be seriously burned.!If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.
