Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
You may lose control of the vehicle. Contin-

Reduced
braking power!
Depress brake
pedal fully!
The electro-hydraulic brake system
is in emergency operation mode.
Considerably 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 in a safe location or as soon
as it is safe to do so and notify an authorized
Mercedes-Benz Center.
Prevent the vehicle from rolling away by
blocking the wheels with wheel chocks or oth-
er sizable objects.

Start engine
The battery has insufficient voltage
and cannot supply sufficient power
to the electro-hydraulic brake sys-
tem.
Start the engine.
The message disappears when sufficient
voltage is available.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated.

The electro-hydraulic brake system
is in emergency operation mode.
Considerable brake pedal force is
required and the stopping distance

Driving while this message is displayed can
result in an accident. Have your brake sys-
tem checked immediately.
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 421).
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!
