Required
The electro-hydraulic brake system
is in emergency operation mode.
Considerably greater brake pedal
force is required and the brake
pedal travel is longer. The stopping
distance is increased.
Stop the vehicle in a safe location or as soon
as it is safe to do so.
Apply the parking brake ( page 63).
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 (
page 253).
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
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!
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”
(
page 434).
