Electric driving: ePOWER
Note Awareness of vehicle reduced when
driven in electric mode
When driving in electric mode, note that, due
to the lack of engine noise, pedestrians and
other traffic might pay less attention to the ve‐
hicle due to missing engine noises. Please
take special care when parking or leaving a
parking space.◀
General information
In ePOWER, the vehicle is driven exclusively
electrically. ePOWER works automatically.
Depending on the charging state of the high-
voltage battery, maximum speed and range
achieved can vary.
For electrical driving, certain Conditions, refer
to page 61, must be satisfied.
Requirements▷State of charge and temperature of the
high-voltage battery is sufficient.▷Selector lever position D or R engaged.▷The accelerator pedal is only slightly de‐
pressed.▷The possible maximum speed for electric
driving is not exceeded.▷The driver's door is closed.
Auto eDRIVE
General information
With each starting operation, Auto eDRIVE is
activated using the Start/Stop button.
In Auto eDRIVE, the vehicle is driven in hybrid
mode corresponding to the various driving sit‐
uations, i.e. the drive alternates between the
combustion engine and electric motor.
SAVE Battery, maintaining charging
state
Should it be necessary, e.g., to conserve the
electrical range for a later point in time on the
trip, the current charging state of the high-volt‐
age battery can be maintained with this func‐
tion.
The function is possible under the following
conditions:▷The fuel fill level is sufficient.▷Engaged selector lever position D▷Drive mode Auto eDrive
Switching on/off

Artificial engine noise
During electric driving up to approx.
20 mph/30 km/h, the engine can produce an
artificial engine noise.
Speakers transmit the noise to the surround‐
ing environment.
As a result, other traffic participants, e.g., pe‐
destrians, can better perceive the vehicle.
Switching on/off

Driving with the combustion
engine: POWER
Depending on the operating state, the com‐
bustion engine is automatically switched on:
▷Selector lever position Sport is set.▷Speed for electric driving is exceeded.▷The high-voltage battery has an insuffi‐
cient charge.▷High-voltage battery is completely
charged, e.g., when driving downhill.▷For improved traction, e.g., on slippery
roads.▷During intense accelerations or on inclines.▷System-related requirement for hybrid
components.▷Adapting to the course of the road when
destination guidance is activated.
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 61, are met.
Assistance for the
combustion engine
Depending on the operating state, the electric
motor provides assistance with additional pro‐
pulsive power.
ASSIST
During normal vehicle operation, the electric
motor assists the combustion engine, depend‐
ing on the situation.
eBOOST Accelerating quickly, such as when passing,
requires the maximum available power from
the electric motor. To do this, apply extra force
to the accelerator pedal.
Energy recovery: CHARGE
The high-voltage battery is recharged in part
through energy recovery. The electric motor
acts as a generator when decelerating and
converts the kinetic energy into electrical en‐
ergy.
Energy can be recovered if the following condi‐
tions are met:
▷The vehicle is moving.Seite 62ControlsDriving62
Online Edition for Part no. 01 40 2 957 072 - X/14

▷Speed higher than approx.
12 mph/20 km/h.▷Selector lever in selector lever position D,
R or S.▷The high-voltage battery is not fully
charged.▷Accelerator pedal is not operated.
Energy cannot be recovered in the following
situations:
▷Selector lever position N is set.▷While drive stability control systems con‐
trol the vehicle, even though it is not indi‐
cated by an indicator light.▷The high-voltage battery is fully charged.▷When temperature of the high-voltage bat‐
tery is very low or very high.
With cold external temperatures, it is pos‐
sible that the energy recovery is tempora‐
rily unavailable after startup.
