electric motor supports the combustion engine.
For this purpose, the electric motor is supplied
by the high-voltage battery.
Electric driving: ePOWER
Under certain conditions, refer to page 102 , the
vehicle is powered only by the electric motor.
Variable drive configuration
The electric motor drives the front axle and the
combustion engine the rear axle. Depending on
the operating condition, the vehicle has the op‐
tions of front-wheel drive, rear-wheel drive or
bundled for four-wheel drive.
Follow instructions for electric driving eDRIVE,
refer to page
102 , driving with the combustion
engine DRIVE, refer to page 104 , and driving
stability, refer to page 153 .
Acoustic pedestrian protection
Depending on the country-specific version, the
system generates a continuous driving noise
during electric driving at low speeds.
Driving with the combustion engine:
POWER
The combustion engine provides the perform‐
ance to move the vehicle. If necessary, the high-
voltage battery is charged at the same time.
The hybrid system always starts the combustion
engine automatically.
Energy recovery: CHARGE
The high-voltage battery is charged while driving
through energy recovery.
The electric motor acts as a generator and con‐
verts the kinetic energy of the vehicle into electri‐
cal energy.
Charging can take place in various situations
while the vehicle is in motion:
▷ When the vehicle is rolling if the accelerator
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.
The mark in the instrument cluster is located
within the CHARGE range.
Sensible driving and early speed reduction are
important to make full use of the energy recovery
feature.
Display
The displays of the hybrid system, refer to
page
118 , provide information about the current
state of the drive and show the system activity in
a chart.
Energy-saving driving
To store energy while driving, read the following
descriptions:
Before driving
eDRIVE allows using the air conditioner even be‐
fore driving off. The stationary climate control, re‐
fer to page
174 , provides more range than using
full air conditioning while driving.
Parked vehicle ventilation during the charging
process can provide maximum range when driv‐
ing off.
During driving
▷ General driving tips, refer to page 193 , for in‐
creasing the range.
▷ Use the eDRIVE system efficiently, refer to
page
186 , for an optimized driving style.
▷ ECO PRO driving mode, refer to page 194 ,
for increasing the range.
▷ Display of hybrid system utilization, refer to
page
119 .
▷ Information on saving fuel, refer to page 193 ,
for reducing fuel consumption.
