The electro-hydraulic brake
system is in emergency opera-
tion mode. Considerably great-
er brake pedal force is required
and the pedal travel is longer.
The stopping distance is in-
creased. If necessary, apply full
pressure to the brake pedal.
The maximum speed is limited
to 55 mph (90 km/h).
̈ Stop the vehicle in a safe location or as soon as it is safe
to do so.
̈ Apply the parking brake (୴ page 55).
̈ Do not drive any further.
̈ Prevent the vehicle from rolling away by blocking the
wheels with wheel chocks or other sizeable objects.
̈ Contact an authorized Mercedes-Benz Center.
or
̈ Call for Roadside Assistance.
Warning! G
Driving while this message is displayed can
result in an accident. Have your brake
system checked immediately.
If the electro-hydraulic 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 are only applied to the front
wheels. Stopping distance is increased!
If there is a malfunction in the
electro-hydraulic brake system, we recom-
mend that the vehicle be transported with
all wheels off the ground using flatbed or ap-
propriate 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”
(
୴ page 370).
