the ability to steer or brake the vehicle. You
may lose control of the vehicle. Continued
driving with a flat tire will cause excessive

Malfunction
The Airbrake locking mecha-

Contact an authorized Mercedes-Benz Center
immediately.
#
Battery/Alternator
Stop Car
The battery is malfunctioning.
The electro-hydraulic brake
system requires electrical
energy and therefore has only
limited operation. Considerably
greater brake pedal force is
required and the pedal travel is
longer. The stopping distance is
increased. If necessary, apply
full pressure to the brake pedal.
Stop the vehicle as soon as it is safe to do so. Adjust
driving to be consistent with reduced braking
responsiveness.
Do not drive any further.
Call Roadside Assistance.
Contact an authorized Mercedes-Benz Center
immediately.

The battery is no longer
charging. Possible causes:
alternator malfunctioning
broken poly-V-belt
Do not forget that the brake
system requires electrical
energy and may be operating
with restricted capability.
Considerably greater brake
pedal force is required and the
pedal travel is longer. The stop-
ping distance is increased. If
necessary, apply full pressure
to the brake pedal.
Stop the vehicle immediately in a safe location and
check the poly-V-belt.
If it is broken:
Do not continue to drive. Otherwise, the engine will
overheat due to an inoperative water pump which
may result in damage to the engine. Contact an
authorized Mercedes-Benz Center.
If it is in order:
Contact an authorized Mercedes-Benz Center imme-
diately. Adjust driving to be consistent with reduced
braking responsiveness.
Read and observe additional messages in the
multifunction display.
The starter battery has been
charged with a battery charger
or jump started.
Contact an authorized Mercedes-Benz Center.
