Battery/Alternator
Stop vehicle
The battery is malfunctioning.
The SBC brake system requires
electrical energy and therefore has
only limited operation. Consider-
ably greater brake pedal force is re-
quired and the stopping distance is
increased.

Stop the vehicle as soon as it is safe to do so.
Adjust driving to be consistent with reduced
braking responsiveness.

Notify an authorized Mercedes-Benz Center.
Visit
workshop!
The battery is no longer charging.
Possible causes:

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake system
requires electrical energy and may
be operating with restricted capa-
bility. Considerably greater brake
pedal force is required and the stop-
ping distance is increased.

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 inoperative
water pump which may result in damage
to the engine. Notify an authorized
Mercedes-Benz Center.
If it is in order:

Drive immediately to the nearest autho-
rized Mercedes-Benz Center. Adjust driv-
ing to be consistent with reduced braking
responsiveness.

Reduced
brake effect
Visit
workshop
The SBC brake system is in emer-
gency operation mode. Consider-
able brake pedal force is required
and the stopping distance is in-
creased.

Continue driving with added caution.

Adjust driving to be consistent with reduced
braking responsiveness.

Visit an authorized Mercedes-Benz Center im-
mediately. Adjust driving to be consistent
with reduced braking responsiveness.
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, see “Towing the vehicle”
(page 408).
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 necessary, apply full pressure to the brake
pedal. Brakes are only applied to the front
wheels. Stopping distance is increased!

Brake fluid
below min. level
Visit
workshop
There is insufficient brake fluid in
the reservoir.

Risk of accident! Stop the vehicle 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.
!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.
Warning
G
Driving with this message displayed can re-
sult in an accident. Have your brake system
checked immediately. Do not add brake flu-
id before checking the brake system. Over-
filling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and
the brake fluid catching fire. You can be se-
riously burned.

Brakes 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 steep grades, shift into a
lower gear to use the engine’s braking power
(page 166).

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