Energy recuperation: CHARGE
With the CHARGE energy recovery, the electric
motors acts as alternators when decelerating and
convert the kinetic energy of the vehicle to elec‐
trical energy.
Energy recuperation partially re-charges the
high-voltage battery.
Anticipatory driving and reducing your speed in
due time are important to be able to use the en‐
ergy recuperation optimally.
Energy can be recuperated if the following con‐
ditions are met:
▷ The vehicle is moving.
▷ Selector lever position B, D or R is engaged.
▷ The accelerator pedal not depressed or only
slightly depressed.
Energy recuperation is shown in the instrument
cluster.
For further information:
Power display, see page 163.
Energy cannot be recovered, for example in the
following situations:
▷ Selector lever position N is engaged.
▷ While driving stability control systems are ac‐
tive or controlling the vehicle, even though
this is not indicated by an indicator light.
▷ The high-voltage battery is completely
charged.
▷ When the temperature of the high-voltage
battery is very low or very high.
In winter, it is possible that energy recupera‐
tion is temporarily not available after starting.
Examples of driving situations
If a deceleration process is anticipated while driv‐
ing, this can be used for energy recuperation.
The following examples of driving situations may
be suitable for this:
▷ Deceleration on a downhill gradient.
▷ Deceleration before a red light.
Avoid late or heavy braking. Instead, decelerate
the vehicle by energy recuperation.
Level of energy recuperation
High energy recuperation and powerful decelera‐
tion are achieved in selector lever position B.
For driving in selector lever position D, the
strength of energy recovery can be adjusted via
iDrive.
▷ Depending on the equipment, adaptive en‐
ergy recovery: energy recovery and decelera‐
tion are automatically adapted to the respec‐
tive driving situation.
Adaptive recuperation, recuperation, see
page 318.
▷ High energy recuperation: the vehicle decel‐
erates powerfully, more energy is fed back
into the high-voltage battery.
▷ Medium energy recuperation.
▷ Low energy recuperation: the vehicle decel‐
erates less powerfully, less energy is fed back
into the high-voltage battery.
Setting the strength of energy recovery
1.
Press the button.

4. Select the desired setting.
Heavily discharged high-voltage
battery
If the high-voltage battery is heavily discharged
during driving, the drive power and some comfort
functions are reduced gradually in order to ex‐
tend the range.
Overheated high-voltage battery
When the vehicle is stationary
In exceptional cases it is possible that the high-
voltage battery overheats significantly when the
