At a glance
Driving off and accelerating require a lot of en‐
ergy. To reduce fuel consumption during high
acceleration and to optimize acceleration, the
electric motor supports the combustion engine.
For this purpose, the electric motor is supplied
by the high-voltage battery.
Energy recovery
The high-voltage battery of the hybrid system is
charged through energy recovery.

Combustion engine
Electric motor
The electric motor acts as a generator and con‐
verts the motion of the vehicle into electric cur‐
rent.

High-voltage battery
Charging can take place in various situations
while the vehicle is being driven:
The concept
When the vehicle is rolling if the accelerator
is not pressed.
The hybrid system makes it possible to optimize
fuel consumption and driving characteristics.
During vehicle braking.
An electric motor supports the combustion en‐
gine in certain driving situations. This lowers fuel
consumption.
When exerting gentle pressure on the brakes,
the vehicle is only braked by the electric motor.
When the brake pedal is depressed further, the
brake system is activated additionally. This is
why only part of the brake energy is used to
charge the high-voltage battery when exerting
firm pressure on the brake.
In addition to this, the electric motor acts like an
alternator: during braking, it converts the vehi‐
cle's kinetic energy into electricity. The current
is stored in the high-voltage battery and is used
to drive the electric motor.
Foresighted driving and the early reduction of
speed are important to make full use of the hy‐
brid characteristics of your vehicle.
The hybrid system combines the following func‐
tions:
Acceleration boost.
Automatic Engine Start/Stop Function
Energy recovery: conversion and storage of
kinetic energy as electric current.
The automatic engine start-stop function, refer
to page 67, switches the combustion engine
off during a stop. Convenience functions such
as the automatic climate control are supplied by
the high-voltage battery and can remain
switched on. The combustion engine starts
again automatically for driving off.
Automatic engine start-stop function: auto‐
matic stopping and starting the combustion
engine when standing, for instance at a traf‐
fic light.
Electric operation of the automatic climate
control.
