After the coasting, the combustion or electric
motor restarts depending on the operating
state.
Driving with the combustion
engine: DRIVE
The combustion engine provides the primary
drive power to move the vehicle. If necessary,
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 for electric driving is exceeded
while accelerating.
▷ The high-voltage battery has an insuffi‐
cient charge.
▷ High voltage battery is completely
charged, e.g., when driving downhill.
▷ During intense accelerations or on inclines.
▷ System-related requirement for hybrid
components.
▷ Adapting to the course of the road when
destination guidance is activated.
Automatic parking while driving
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page
70 , 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,
requires 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 con‐
vert kinetic energy into electrical power when
braking 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 re‐
cover 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
cluster, refer to page
86 .
Parking brake
The concept
The parking brake is used to prevent the vehi‐
cle from rolling when it is parked.
