Transmission position P with the ignition
off
When the ignition is switched off, position P is
engaged automatically. When in an automatic
car wash, for example, ensure that the ignition is
not switched off accidentally.◀
The ignition is switched off automatically in the
following situations while the vehicle is station‐
ary and the engine is off:▷When locking the vehicle, and when the low
beams are activated.▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available when
the low beams are switched off.▷When opening and closing the driver door, if
the driver's seat belt is unbuckled and the
low beams are switched off.▷While the driver's seat belt is unbuckled, if
the driver's door is open and the low beams
are switched off.
When the ignition is switched off, by opening or
closing the driver's door or unbuckling the driv‐
er's seat belt, the radio ready state remains ac‐
tive.

Electric driving: eDRIVE
Requirements
Electric driving is possible under the following
conditions:
▷The speed does not exceed 35 mph, approx.
60 km/h.▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is engaged.▷The drive system is at operating tempera‐
ture.▷The accelerator pedal is only slightly de‐
pressed.▷The driver's door is closed.
In addition, the combustion engine is switched
off during braking even below 50 mph, approx.
80 km/h or when coasting below 35 mph, ap‐
prox. 60 km/h.
In ECO PRO mode, already when coasting be‐
low 100 mph, approx. 160 km/h.
Possible cruising range
Depending on the charge of the high-voltage
battery, the vehicle can generally be driven us‐
ing electric power up to 2 miles, approx. 3.5 km.
Driving with the combustion
engine: DRIVE
The combustion engine provides the drive
power to propel the vehicle. The high-voltage
battery is charged at the same time.
Automatic start while driving
The combustion engine is automatically started
under the following conditions while driving:
▷Transmission position M/S is engaged.▷The speed does not exceed 35 mph, approx.
60 km/h.▷The high-voltage battery charge is insuffi‐
cient or it is fully charged, such as when driv‐
ing downhill.▷The required power output is increased,

Automatic stopping while driving
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 67, are met.
Assistance for the
combustion engine
The combustion engine provides the primary
drive power to move the vehicle.
The electric motor provides assistance as
needed with additional propulsive 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, re‐
quires the maximum available power from the
electric motor. To do this, apply extra force to
the accelerator pedal.
Energy recovery: CHARGE
The hybrid system makes it possible to convert
kinetic energy into electrical power, such as
when braking. This recovered energy charges
the high voltage battery. If necessary, this stored
power is output to the electric motor.
The following conditions must be met to recover
kinetic energy:▷The vehicle is moving.▷Selector lever position D, M/S is engaged.▷The high-voltage battery is not fully
charged.
Energy recovery displays in the instrument clus‐
ter, refer to page 81.
