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 Comfort drive 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 (

page 253).
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 80 mph
(130 km/h) (
Y
page 253).
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 engine is switched off automatically, includ-
ing when:
R
the driver removes his/her foot from the
accelerator in the Comfort drive program and
a speed of 80 mph (130 km/h) is not excee-
ded (
Y
page 253)
R
the engine has reached its operating temper-
ature
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, maintain
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
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 being charged
(

Automatic engine start
The automatically switched-off internal combus-
tion engine starts automatically in certain situa-
tions, if:
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 Sport drive pro-
gram or to manual gearshifting
R
the condition of charge 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 a generator and produces the
necessary energy for the auxiliary consumers
and charges the high-voltage battery
Overrun mode is available in the Comfort drive
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:
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
