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 au-
thorized Mercedes-Benz Center. Ad-
just 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.
Undervoltage
Charge battery
The battery has insufficient voltage.

Start the engine (

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 Service Booklet.

Have the brake pads replaced as soon
as possible.

Brake malfunction
Stop vehicle
The SBC brake system is in the emergen-
cy operation mode. Considerably greater
brake pedal force is required and the
stopping distance is increased.
Do not exceed a speed of 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.

Service brake
!
Visit workshop!
There are malfunctions, but the SBC
brake system is operating normally.

Visit an authorized Mercedes-Benz
Center as soon as possible.
Brake overheated!
Drive carefully!
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 159).

Cautiously continue driving so that
the air stream will cool down the
brakes.
Release

You are driving with the parking brake
set.

Release the parking brake

Brake fluid
Visit workshop!
There is insufficient brake fluid in the
reservoir.

Risk of accident! Stop the vehicle and
notify an authorized Mercedes-Benz
Center. Do not add brake fluid! This
will not solve the problem.
Warning!
G
Driving while these messages are displayed
can result in an accident. Have your brake
system checked immediately.
If there is a malfunction in the SBC 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
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km / h). For more infor-
mation, refer to “Towing the vehicle”
(page 381).
If the SBC brake system enters its emergen-
cy operation mode, the driver must apply
significantly greater brake pedal pressure
and depress the pedal much further than
normal to obtain braking effect. If neces-
sary, apply full pressure to the brake pedal.
Brakes may only be applied to the front
wheels. Stopping distance is increased!
Low brake fluid in the reservoir may cause
the braking system to fail!
Don’t 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.iIf 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.!Brake pad thickness must be visually
inspected by a qualified technician at
the intervals specified in the Service
Booklet.
