Automatic start while driving
The combustion engine is automatically started
under the following conditions while driving:
▷ Transmission position M/S is engaged.
▷ The speed for electric driving is exceeded
while accelerating.
▷ 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,
such as due to the accelerator pedal position
or driving uphill.
▷ System-related requirement for hybrid
components.
▷ Preparation for an upcoming route section
with activated destination guidance.
Automatic stopping while driving
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 66, 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 when brak‐
ing and coasting. This recovered energy
charges the high voltage battery. If necessary,
this stored electrical energy is output to the
electric motor.
The following conditions must be met to recover
kinetic energy:
▷ The vehicle is moving.
▷ Transmission 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 80.
