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 cur- rently provide.
Noiseless start operation is dependent on the
outside temperature and the operating temper-
ature of the internal combustion engine. If not all
conditions for noiseless start operation are ful-
filled, the vehicle starts with the internal com-
bustion engine. 266

Driving tips General driving tips
Drive carefully and maintain a suitable distance from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt braking.
During partial electric drive, pulling away and
acceleration, the electric motor supports the
internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor operates as an alter-
nator.
Further information on the ECO start/stop func-
tion (Y page 269).
Additional driving tips (Y page 194).
Stationary vehicle
If the vehicle is stopped, the combustion engine is, for the most part, switched off. Automatic
climate control continues to function. The elec-
tro-mechanically assisted steering gear allows
use of the power steering without loss of com-
fort. Acceleration
Depending on the operating mode, pulling away and driving under low load conditions are per-
formed:
R entirely by electric propulsion
R in combination with the internal combustion
engine
When accelerating rapidly under increased or
full load, increased boost mode is utilised. The
electric motor supports the combustion engine
by providing additional drive torque.
Overrun mode or braking There are three possible operating modes when
the hybrid vehicle is decelerating:
R When coasting and decelerating, energy recu-
peration is already taking place (Y page 259).
The electric motor functions as an alternator
and stores the recuperated energy in the
high-voltage battery.
R When braking gently, the electric motor
increases the deceleration of the vehicle.
Energy recuperation is increased
(Y page 259). The electric motor functions as
an alternator and stores the recuperated
energy in the high-voltage battery.
R During heavy braking, the service brake is
also used to slow down the vehicle. Both sys-
tems work together.
Driving in the city In urban traffic, energy is recuperated during
frequent deceleration phases.
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (Y page 269).
Driving on inter-urban roads The following phases are possible when driving
on inter-urban roads:
R rapid acceleration (boost mode)
R energy recuperation
R electric operation mode
The vehicle can be driven by the electric motor
alone up to a speed of approximately 120 km/h.
Depending on the characteristics of the route,
there may be a lot of recuperated energy avail-
able. This reduces consumption and emissions. 268

Driving on the motorway
When driving on a motorway, switching off the
combustion engine has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his/her foot from the
accelerator pedal in the Comfortdrive program
and a speed of 130 km/h is not exceeded, the
combustion engine is automatically switched
off.
Further information on the automatic engine
switch-off (Y page 269).
ECO start/stop function General notes
The ECO start/stop function switches the com-
bustion engine off automatically when the vehi-
cle stops moving and at speeds below
130 km/h (Y page 269).
All vehicle systems remain active, e.g. the auto-
matic climate control.
The ECO start/stop function is neither available
in the Sport drive program nor during manual
shifting.
Automatic engine switch-off
The internal combustion engine is switched off
automatically if:
R the driver removes his/her foot from the
accelerator in the Comfortdrive program and
a speed of 130 km/h is not exceeded
(Y page 269)
R the internal combustion engine has reached
its operating temperature
R the driver only slightly depresses the accel-
erator pedal in order to, for example, maintain the current speed for a limited distance
R the bonnet is closed and engaged properly
R the high-voltage battery is charged suffi-
ciently
R no malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if:
R the self-diagnosis function of the engine man-
agement is active
R there is a malfunction in the hybrid drive sys-
tem R
the climate control of the vehicle requires it
R the high-voltage battery is charging
(Y page 264).
Automatic engine start
The internal combustion engine, which has been automatically switched-off, starts automatically
in certain situations, when:
R the power demand from the driver via the
accelerator pedal is greater than the electric
motor alone can provide
R the driver switches to the Sportdrive pro-
gram or to manual gearshifting
R the charge level of the high-voltage battery
has reached the lower limit
R the driver has selected the CHARGE operating
mode
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 an alternator and produces the
necessary energy for the auxiliary consumers
and charges the high-voltage battery
Overrun mode is available in the Comfortdrive
program at speeds below 130 km/h.
Route-based operating strategy For the route-based operating strategy, the sys-
tem factors in information about the expected
route when route guidance is active.
The information on the route is provided by the
multimedia system and includes the following:
R road categories
R speed limitations
The use of electric energy is automatically opti- mally distributed from the beginning to the end
of the journey, using information about the
route. The distribution is pre-emptive and takes
into consideration:
R the sections of the journey ahead
R the energy consumption on the whole route Plug-in hybrid operation
