-
The yellow ABS indicator
lamp comes on while driving.
The ABS has detected a malfunction and
has switched off. The BAS and the ESP are
also switched off (see messages in dis-
play).
The SBC brake system is still functioning
normally but without ABS available.
If the ABS control unit is malfunctioning
the automatic transmission may also be
malfunctioning.
Continue driving with added caution. Wheels
may lock during hard braking, reducing
steering capability.
Read and observe messages in the display
(page 304).
Have the system checked at an authorized
Mercedes-Benz Center immediately.
Failure to follow these instructions increases
the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS was switched off.
When the voltage is above this value again, the
ABS is operational again.
If necessary, have the generator and battery
checked.

Tire pressure
Caution
tire defect!
The tire inflation pressure in
one or more tires is dropping.
Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. Observe the traffic
situation around you.
Temporarily repair tire using TIREFIT (

contact Roadside Assistance. If tire cannot be tempo-
rarily repaired using TIREFIT, contact Roadside Assis-
tance.

excessive heat build-up and possibly a fire.
Warning!
G
Have worn or damaged tires replaced in
pairs (front pair or rear pair). Otherwise the
