Driving while one of the previous messages 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 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 recommendedVehicle status messages in the multifunction display237Practical hints230_AKB; 6; 22, en-USd2ureepe,Version: 2.11.8.12009-07-28T18:49:58+02:00 - Seite 237Z

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 to30 miles (50 km) and at a speed not to exceed
30 mph (50 km/h). For more information, see
“Towing the vehicle”.Display messagesPossible causes/consequences and M Solutions$

sufficient power to the electro-hydraulic brake system.XStart the engine.
The message disappears when sufficient voltage is
available.GWarning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and lead to death. Do not
run the engine in confined areas (such as a
garage) which are not properly ventilated.Display messagesPossible causes/consequences and M Solutions#Brake WearThe brake pads have reached their wear limit.XHave the brake pads replaced as soon as possible.
!
Brake pad thickness must be visually inspected by a qualified technician at the intervals
specified in the Maintenance Booklet.
GWarning!
Have brake pad replacement and other work
on the electro-hydraulic brake system carried
out by qualified technicians only. Contact an
authorized Mercedes-Benz Center for further
information.
The electro-hydraulic brake system must be
deactivated prior to working on the system.
High pressure is intermittently built up in the
system as part of its automatic self-test.
In addition, the system is automatically
activated when the vehicle is unlocked by
remote control, when the driver or passenger
door is opened, when the SmartKey in the
starter switch is turned to position 1 or the
KEYLESS-GO start/stop button is pressed
once, when the brake pedal is depressed or
when the parking brake is released. Failure to
deactivate the system prior to maintenance
will cause brake pistons to extend and brake
fluid to leak, which may result in injuries
(contusions and acid burns). Extended brake
pistons may also cause injury.238Vehicle status messages in the multifunction displayPractical hints

Do not add brake fluid before checking the

hot engine parts and the brake fluid catching
fire. You can be seriously burned.

During severe operation conditions and stop-and-go city
traffic, the coolant temperature may rise close to 248‡
(120†).
GWarning!
Driving when your engine is overheated can cause some fluids which may have leaked into the
engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until the engine has cooled down.
! The engine should not be operated with the coolant temperature above 248‡ (120†).
Doing so may cause serious damage which is not covered by the Mercedes-Benz Limited
Warranty.
