Driving with combustion engine:
DRIVE
The combustion engine, refer to page 72,
provides the primary performance to move the
vehicle. If necessary, the high-voltage battery
is charged at the same time.
The hybrid system always starts the combus‐
tion engine automatically.
Energy recovery: CHARGE
The high-voltage battery of the hybrid system
is charged through energy recovery while driv‐
ing.
The electric motor acts as a generator and
converts the kinetic energy of the vehicle into
electric current.
Charging can take place in various situations:
▷ When the vehicle is coasting if the acceler‐
ator pedal is not pressed.
▷ During vehicle braking.
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.
Foresighted driving and the early reduction of
speed are important to make full use of the hy‐
brid characteristics of the vehicle.
Coasting
The engine is automatically switched off. This
driving condition of rolling is referred to as
coasting, refer to page 71.
Auxiliary functions of the automatic
climate control
The hybrid system makes it possible to oper‐
ate the automatic climate control prior to driv‐
ing off and with the combustion engine
switched off.
Using the auxiliary air conditioning and residual
cooling functions, the vehicle interior can be
cooled immediately prior to departure and if
the trip is interrupted.
▷ Residual cooling, refer to page 155.
▷ Auxiliary air conditioning, refer to
page 155
Adapting to the course of the road
When the navigation system destination guid‐
ance is active, the hybrid system uses the ex‐
isting navigation data. Hybrid operation adapts
to the specific route sections. These may be:
▷ Steep gradients.
▷ Arrival in the destination zone.
Pay attention to the notes in Adapting to the
course of the road, refer to page 84.
Display
The displays of the hybrid system, refer to
page 82, provide information about the cur‐
rent state of hybrid operation and show the
system activity in a chart.
Energy-saving driving
To save energy while driving, read the follow‐
ing information:
▷ Saving fuel, refer to page 180.
▷ Using the hybrid system efficiently, refer to
page 172
▷ ECO PRO mode, refer to page 181.
▷ Adapting to the course of the road, refer to
page 84.
Safety information
Read the information on safe handling of the
high-voltage system, refer to page 34.
Long-term
Follow the instructions for vehicle storage and
for longer idle periods, refer to page 231
