Electric operation mode and charging the
high-voltage battery The electric motor is operating as a genera-
tor, e.g. in overrun mode and when braking.
The kinetic energy of the vehicle is converted into electrical energy. The high-voltage bat-
tery is being charged.
The arrows for the energy flow are shown in
green.

Additional point of resistance in the hap-
tic accelerator pedal
The maximum available electric performance is indicated by a tangible point of resistance
in the haptic accelerator pedal.
The additional point of resistance is available
in E-MODE operating mode (Y page 280)
If you depress the haptic accelerator pedal
beyond the pressure point, the combustion
engine is switched on.
Double pulses in the haptic accelerator
pedal
A tangible double pulse in the haptic acceler- ator pedal gives you a recommendation to
release the accelerator pedal. By this means, in HYBRID, E-MODEorE-SAVE operating
mode the combustion engine can be switched
off and disconnected from the power train
(overrun mode).
The double pulse is available in drive program
E+ (Ypage 285).
After the accelerator pedal has been
released, the coasting characteristics of the
vehicle are adapted to the traffic conditions.
To avoid getting too close to the vehicle in
front, you must apply the brakes manually
when necessary.
Driving tips General driving tips
Drive carefully and maintain a safe distance
from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt brak-
ing.
During partial electric driving, pulling away
and acceleration, the electric motor supports
the internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor will operate as a
generator.
Further information on the ECO start/stop
function (Y page 288).
Additional driving tips (Y page 224).Stationary vehicle
If the vehicle is stopped, the combustion
engine is, for the most part, switched off.
Automatic climate control continues to func-
tion. The electromechanically assisted steer-
ing gear allows you to use the power steering
without reduced comfort.
Acceleration
Depending on the operating mode, pulling
away and driving under low load conditions
are performed:
R entirely by electric propulsion
R in combination with the internal combus-
tion engine
When accelerating at an increased or full
load, boost mode is utilized. The electric
motor supports the internal combustion
engine by providing additional torque when
the accelerator is depressed rapidly.
Overrun mode or braking
There are three possible operating modes
when the hybrid vehicle is decelerating:
R energy recovery takes place even when the
vehicle is decelerating purely in overrun
mode (Y page 276). The electric motor
operates as a generator and stores the
recovered energy in the high-voltage bat-
tery.
R when the brakes are applied lightly, the
vehicle is slowed down further by the elec-
tric motor. This increases the energy recov- ery taking place (Y page 276). The electric
motor operates as a generator and stores
the recovered energy in the high-voltage
battery.
R when the brakes are applied with greater
force, the service brakes are also used to
slow the vehicle down. The two systems
work together.
Urban driving
Energy is recuperated during frequent decel-
eration and stopping in city traffic. PLUG-IN HYBRID operation
287Driving and parking Z
The vehicle can be driven by the electric
motor alone up to a speed of approximately
130 km/h.
The vehicle is driven by the electric motor
alone only when all conditions for the auto-
matic engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (Y page 288).
Driving on inter-urban roads
The following phases are possible when driv-
ing on inter-urban roads: R rapid acceleration (boost mode)
R constant energy consumption
R energy recuperation
R electric operation mode
A great deal of recovered energy may be
available, depending on the route profile. This reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption andemissions are favorably influenced in partic-
ular by reduced power losses.
The internal combustion engine will be
switched off automatically, if:
R the driver removes his foot from the accel-
erator pedal in drive program Eand a speed
of 130 km/h is not exceeded
R the driver removes his foot from the accel-
erator pedal in drive program E+and a
speed of 180 km/h is not exceeded.
Further information on the automatic engine
switch-off (Y page 288).
ECO start/stop function General notes
The ECO start/stop function switches the
internal combustion engine off automatically
when the vehicle stops moving and at high
speeds (Y
page 289).
All vehicle systems remain active, e.g. the
automatic climate control. The ECO start/stop function is only available
in drive programs Eand E+. Electric-only
operation is only possible in drive programs E
and E+. Additional information for drive pro-
grams Eand E+(Ypage 285).
Automatic engine switch-off
The engine is switched off automatically,
including when:
R the driver removes his foot from the accel-
erator in drive program Eand a speed of
130 km/h is not exceeded (Y page 289)
R the driver removes his foot from the accel-
erator in drive program E+and a speed of
180 km/h is not exceeded (Y page 289)
R the engine has reached its operating tem-
perature
R the driver’s seat belt is fastened and the
driver’s door is closed
R the driver only slightly depresses the accel-
erator pedal in order to, for example, main- tain the current speed for a limited distance
R the hood is closed and engaged properly
R the high-voltage battery is charged suffi-
ciently
R there are no malfunctions in the hybrid sys-
tem
The internal combustion engine will not be
switched off automatically, if:
R the self-diagnosis function of the engine
control unit is still active
R there is a malfunction in the hybrid system
R the climate control of the vehicle requires it
R the high-voltage battery is being charged
(Y page 282)
R automatic emissions tests are running 288
PLUG-IN HYBRID operationDriving and parking
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
