Battery/Alternator
Stop car
The battery is malfunctioning.
The electro-hydraulic brake system
requires electrical energy and
therefore has only limited opera-
tion. Considerably greater brake
pedal force is required and the stop-
ping distance is increased.
̈ Stop the vehicle in a safe location. Adjust driv-
ing to be consistent with reduced braking re-
sponsiveness.
̈ Contact an authorized Mercedes-Benz Cen-

Warning! G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated.
