Battery/Alternator
Stop vehicle
The battery is malfunctioning.
The electro-hydraulic brake system re-
quires electrical energy and therefore has
only limited operation. Considerably
greater brake pedal force is required and
the stopping distance is increased.
̈ Stop the vehicle as soon as it is safe
to do so. Adjust driving to be consis-
tent with reduced braking responsive-
ness.
̈ Notify an authorized Mercedes-Benz
Center.
Low voltage
Start engine
The battery has insufficient voltage. ̈ Start the engine (୴ page 49).
