Vehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.

The concept
The hybrid system makes it possible to opti‐
mize fuel consumption and driving characteris‐
tics.
An electric motor assists the combustion en‐
gine. In certain driving situations, the vehicle
can also be driven using only electric power,
thereby reducing fuel consumption.
In addition to this, the electric motor acts like
an alternator: during braking and coasting, it
converts the vehicle's kinetic energy into elec‐
tricity. The current is stored in the high-voltage
battery and is used to drive the electric motor.
The hybrid system combines the following
functions:
▷ Acceleration boost: ASSIST and eBOOST.
▷ Electric driving: eDRIVE.
▷ Automatic stopping of the combustion en‐
gine during coasting: coasting.
▷ Driving with the combustion engine: DRIVE
▷ Energy recovery: CHARGE.
▷ Automatic engine start-stop function.
▷ Auxiliary functions of the automatic climate
control.
▷ Adapting to the course of the road.
Functions
Electric driving: eDRIVE
Under certain conditions, refer to page 70 ,
the vehicle is powered only by the electric mo‐
tor.
Acceleration boost: ASSIST and
eBOOST
Driving off and accelerating require a lot of en‐
ergy.
To optimize acceleration and to reduce fuel
consumption, the electric motor boosts the
combustion engine. To do this, the electric
motor uses the energy saved in the high volt‐
age battery.
The ASSIST acceleration boost is automati‐
cally controlled and is not indicated in the in‐
strument cluster.
