Mercedes-Benz M-Class Hybrid 2010 Owners Manual - Manual (Page 13)

Introduction
The HYBRID technology combines an
economical combustion engine with a
powerful hybrid transmission. The HYBRID
system selects the most efficient operating
mode for each driving situation automatically.
You can drive the vehicle in the usual manner.
The HYBRID system turns the combustion
engine off as often as possible in order to save
fuel.
Depending on various conditions such as the
charging level of the high-voltage battery or
the operating temperature, the vehicle can
run on electrical energy alone. These
conditions as well as the degree to which the
driver accelerates determine the vehicle
speed and range that can be achieved for all-
electrical driving.
G
Warning!
When the READY indicator in the instrument
cluster is on while the combustion engine is
off, the combustion engine has been turned
off automatically. All vehicle systems
continue to be active as long as the ignition is
switched on. When you open the driver’s door
and unbuckle the seat belt with the READY
indicator on, while the automatic
transmission is in position
N or P, the
combustion engine starts automatically.
Therefore, always do the following before
leaving the vehicle:
R Engage the parking brake.
R Shift the automatic transmission into park
position
P.
R Switch off the ignition. The READY indicator
goes out.
Driving off and accelerating consumes the
most energy. Thus, the hybrid transmission
supports the combustion engine with the
energy stored in the high-voltage battery. The
energy is also used for electrical driving, for
operation of the electric compressor of the
cooling system and to support the 12-volt on-
board power supply. The hybrid drive thereby
contributes significantly to the fuel economy
of your vehicle.
For information on driving with HYBRID, see
(
Y page 16).
The current operating mode of the HYBRID
system can be displayed in the instrument
cluster (
Y page 13) and in the COMAND
display ( Y page 13).
The COMAND can also display a chart of the
fuel consumption and the electric power that
has been generated (
Y page 15).
RBS (Recuperative Brake System)
With the RBS activated ( Y page 9), the hybrid
transmission functions as a generator when
coasting and braking. HYBRID converts the
energy of movement into electric power and
stores it in the high-voltage battery. The high-
voltage battery does not require additional
charging by other means.
