Reduced
braking power!
Depress brake
pedal fully!
The SBC brake system is in emer-
gency 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 and notify an authorized
Mercedes-Benz Center.

Prevent the vehicle from rolling away by
blocking the wheels with wheel chocks or oth-

The SBC brake system is in emer-

able brake pedal force is required
and the stopping distance is in-
creased.

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!
