not disappear:
Have the generator (alternator) and the battery
checked.

Distronic
currently unavailable
See Operator’s Manual
Distronic* is deactivated because the
functionality is impaired by external in-
terferences, e.g. high-frequency sources
such as too stations, speed measuring
systems etc.
Leave the area of the external interference.
Activate Distronic* again (
page 223) when
the message

again ap-
pears.
Distronic* is deactivated because the
Distronic* sensor has not sensed any
other vehicles or objects, e.g. road sign
or such, for a long time.
Activate Distronic* again (

This message will appear whenever the
trunk is open.
Close the trunk.
#
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 stopping distance is
increased.
Stop immediately in a safe location or
as soon as it is safe to do so 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 re-
sult in damage to the engine. Notify
an authorized Mercedes-Benz Center.
If it is intact:
Drive immediately to the nearest
authorized Mercedes-Benz Center.
Adjust driving to be consistent with
reduced braking responsiveness.

Check
brake fluid level
There is insufficient brake fluid in the
reservoir.
Risk of accident! Stop the vehicle in a
safe location and notify an authorized
Mercedes-Benz Center. Do not add
brake fluid! This will not solve the
problem.
Warning!

Driving with the messages
Check brake
fluid level
displayed can result in an ac-
cident. Have your brake system checked im-
mediately.
Do not add brake fluid before checking the
brake system. Overfilling the brake fluid res-
ervoir can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You can be seriously burned.
!
If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks.
