SAVE BATTERY
General information
The current charge state of the
high-voltage battery can be
maintained or increased with
SAVE BATTERY. The electric
range can be conserved in this
way for a later point in the trip, for instance.
This charging process increases the average
fuel consumption.
The acceleration boost by the electric motor
may be restricted.
The function is only available if sufficient fuel is
available and in selector lever position D.
Activating SAVE BATTERY
Press the button down repeatedly, un‐
til SAVE with the battery symbol is dis‐
played in the instrument cluster.
When pressing the button, the current eDRIVE
setting is graphically displayed on the Control
Display.
Auto Start/Stop function, coasting
Concept
The combustion engine is automatically stop‐
ped and disengaged from the drivetrain. This
driving condition of rolling is referred to as
coasting.
Functional requirements
Coasting is possible:
▷ The high-voltage battery is sufficiently
charged.
▷ Transmission position D is engaged.
▷ The drive system is at operating tempera‐
ture.
▷ GREEN Mode: when coasting, without oper‐
ating the brake, at speeds below 100 mph,
approx. 160 km/h.
After coasting, the combustion or electric mo‐
tor restarts depending on the operating state.
Acoustic pedestrian protection
Concept
Depending on the country-specific version, the
system generates a continuous driving noise at
standstill with the drive-ready state activated
and during electric driving up to approx.
20 mph/30 km/h.
A speaker system broadcasts the noise to the
surroundings.
As a result, other traffic participants, for in‐
stance pedestrians or cyclists, can better per‐
ceive the vehicle.
Driving with the combus‐
tion engine: POWER
Concept
The combustion engine provides the main drive
power to move the vehicle. If necessary, the
high-voltage battery is charged at the same
time.
Functional requirements
Automatic starting while driving
The combustion engine is automatically started
under the following conditions while driving:
▷ During intense accelerations or on uphill
grades.
▷ By pressing the accelerator pedal beyond
the resistance point at the full throttle posi‐
tion, kickdown.
▷ The high-voltage battery has an insufficient
charge.
▷ Selector lever position M/S is engaged.
▷ The speed for electric driving is exceeded
while accelerating.
