The vehicle starts in electric mode without the
internal combustion engine (noiseless start).
The internal combustion engine starts only
after the power demanded by the driver
exceeds the available power that the electric motor can currently provide.
Noiseless start operation is dependent on the
outside temperature and the operating tem-
perature of the internal combustion engine. If
not all conditions for noiseless start operation are fulfilled, the vehicle starts with the inter-
nal combustion engine. X

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

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
