Automatic engine start
The automatically switched-off internal com-
bustion engine starts automatically in certain situations, if:
R the power demand from the driver via the
accelerator pedal is greater than the elec-
tric motor alone can provide
R the driver switches to drive program Sor M
R the condition of charge of the high-voltage
battery has reached the lower limit
R the settings of the automatic climate con-
trol require it, e.g. at external temperatures
above 30 †
Overrun mode
In overrun mode, the combustion engine is
switched off and is disconnected from the
drive train. The electric motor:
R generates low thrust, which corresponds to
the overrun mode of an active combustion
engine
R functions as a generator and produces the
necessary energy for the auxiliary consum-
ers and charges the high-voltage battery
Overrun mode is possible in the following
speed range:
R in drive program Ebelow 130 km/h
R in drive program E+below 180 km/h
In drive program E+, after the accelerator
pedal has been released the coasting char-
acteristics of the vehicle are adapted to the
traffic conditions. Further information about
the haptic accelerator pedal (Y page 286).
Map-based energy management For map-based energy management, the sys-
tem factors in information about the expec-
ted route when route guidance is active.
The information on the route is provided by
COMAND and includes the following:
R road categories
R speed limitations
R data on downhill gradients The use of electric energy is automatically
optimally distributed from the beginning to
the end of the journey, using information
about the route. The distribution is pre-emp-
tive and takes into consideration:
R the sections of the journey ahead
R the energy consumption on the whole route
The condition of charge of the high-voltage
battery is thus systematically controlled. In
addition, the control function takes into
account that:
R the fuel saving through the use of electrical
energy can vary, dependent on the route
(e.g. urban, interurban or highway)
R the use of electrical energy is held available
for electric driving, particularly for urban
routes
The vehicle thus automatically selects the
optimum driving mode for the respective sec- tion of the route.
Map-based energy management is available
under the following conditions:
R drive program E+is selected
R HYBRID driving mode is selected
R active route guidance is activated
R suitable map data is available
When map-based energy management is
engaged, the area in front of the vehicle in the
multifunction display will be green. Parking
X Apply the electric parking brake.
The red !indicator lamp in the instru-
ment cluster lights up.
X Use the DIRECT SELECT lever to shift the
automatic transmission to P.
X Switch the ignition off.
The READY indicator in the instrument clus-
ter goes out.
