Starting the engine
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.

General notes
The ECO start/stop function switches the com-
bustion engine off automatically when the veh i-
cle stops moving and at speeds below 80 mph
(13 0km/ h)(
Ypage 24). 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

Automatic engine switch-off
The engine is switched off automatically, includ-
ing when:
Rthe driver removes his/her foot from the
accelerator in the Comfortdrive program and
a speed of 80 mph (130 km/h) is not excee-
ded (
Ypage 24)
Rthe engine has reached its operating temper- ature
Rthe driver’s seat belt is fastened and the
driver’s door is closed
Rthe driver only slightly depresses the accel-
erator pedal in order to, for example, maintain
the current speed for a limited distance
Rthe hood is closed and engaged properly
Rthe high-voltage battery is charged suffi-
ciently
Rno malfunctions are present in the hybrid
drive system
The internal combustion engine will not be
switched off automatically, if:
Rthe self-diagnosis function of the engine man-
agement is active
Rthere is a malfunction in the hybrid drive sys-
tem
Rthe climate control of the vehicle requires it
Rthe high-voltage battery is charging

tion engine starts automatically in certain situa-
tions, if:
Rthe power demand from the driver via the
accelerator pedal is greater than the electric
motor alone can provide
Rthe driver switches to the Sportdrive pro-
gram or to manual gearshifting
Rthe condition of charge of the high-voltage
battery has reached the lower limit
Rthe driver has selected the CHARGE operating

Overrun mode
In overrun mode, the combustion engine is
switched off and is disconnected from the drive
train. The electric motor:
Rgenerates low thrust, which corresponds to
the overrun mode of an active combustion
engine
Rfunctions as a generator and produces the
necessary energy for the auxiliary consumersand charges the high-voltage battery
Overrun mode is available in the Comfortdrive
program at speeds below 80 mph (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:
Rroad categories
Rspeed 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:
Rthe sections of the journey ahead
Rthe energy consumption on the whole route The condition of charge of the high-voltage bat-
tery is thus systematically controlled. In addi-
tion, the control function takes into account
that:
Rthe fuel saving through the use of electrical
energy can vary, dependent on the route (e.g.
urban, interurban or highway)
Rthe use of electrical energy is held available
for electric driving, particularly for urban
routes
The vehicle thus automatically selects the opti-
mum driving mode for the respective section of
the route.
The route-based operating strategy is available
under the following conditions:
Rthe Individual drive program is selected
Rin theIndividual drive program, the ECO set-
ting is selected under Drive
RHYBRID driving mode is selected
Ractive route guidance is activated
Rsuitable map data is available
When the route-based operating strategy is
being used, the area in front of the vehicle is
shown as green in the multifunction display.

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 braking.
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 gen- erator.
Further information on the ECO start/stop func-
tion (
Ypage 23).
You can find further driving tips in the vehicle
Operator's Manual.
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-
tromechanically assisted steering 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 per-
formed:
Rentirely by electric propulsion
Rin combination with the internal combustion
engine
When accelerating rapidly under increased or
full load, increased boost mode is utilized. 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:
Renergy recovery takes place even when the
vehicle is decelerating purely in overrun mode
(
Ypage 20). The electric motor operates as a
generator and stores the recovered energy in
the high-voltage battery
Rwhen the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor. This increases the energy recovery
taking place (
Ypage 20). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery
Rduring heavy braking, the service brake is also
used to slow down the vehicle. The two sys-
tems work together
26Driving tips
Driving and parking

Urban driving
In city traffic, energy is recuperated during fre-
quent deceleration phases.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 80 mph
(130 km/h).
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 (
Ypage 23).
Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
Rrapid acceleration (boost mode)
Renergy recuperation
Relectric operation mode
The vehicle can be driven by the electric motor
alone up to a speed of approximately 74 mph
(120 km/ h).
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
When driving on a highway, 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 80 mph (130 km/h) is not excee-
ded, the combustion engine is automatically
switched off.
Further information on the automatic engine
switch-off (
Ypage 23).
