CONTROLS
Reduced deceleration
Warning
Without energy recovery, the braking effect of
the electric motor is unavailable. The vehicle
could roll further than anticipated. There is a
risk of accident. Adjust driving style to traffic
conditions. Watch surrounding traffic closely
and actively intervene where appropriate.
In the event of danger such as with locked
wheels, energy recovery and thus deceleration
is reduced in order to prevent unstable driving
situations.
Energy recovery
Energy recovery is also called recuperation.
With energy recovery, the electric motors act
as alternators when decelerating and convert
the kinetic energy of the vehicle to electrical
energy.
The high-voltage battery is recharged in part
through energy recovery.
Energy can be recovered if the following condi-
tions are met:
▷
The vehicle is moving.
▷
Selector lever position B, D or R is set.
▷
The accelerator pedal is not depressed or
only slightly depressed.
The energy recovery is displayed in the instru-
ment cluster.
Additional information:
Power gauge, refer to page 144.
Energy cannot be recovered in the following
situations, for instance:
▷
Selector lever position N is engaged.
▷
While drive stability control systems are ac-
tive or adjusting the vehicle, even though
this is not indicated by an indicator light.

▷
The high-voltage battery is fully charged.
▷
When temperature of the high-voltage bat-
tery is very low or very high.
In winter the energy recovery may be tem-
porarily unavailable after startup.
Driving situations for energy recovery
If deceleration is foreseeable while driving, this
can be used for energy recovery.
The following driving situations may be suita-
ble for this:
▷
Decelerating downhill.
▷
Deceleration before a red traffic light.
Avoid late or strong braking. Instead, deceler-
ate the vehicle using energy recovery.
Strength of recuperative braking
In selector lever position B, the energy recov-
ery is high and the deceleration is pronounced.
For driving in selector lever position D, the
strength of recuperative braking can be ad-
justed via iDrive.
▷
Depending on the equipment, adaptive en-
ergy recovery: energy recovery and decel-
eration are automatically adapted to the re-
spective driving situation.
Adaptive recuperation, recuperative brak-
ing, refer to page 279.
▷
High energy recovery: The vehicle deceler-
ates fast, and more energy is returned to
the high-voltage battery.
▷
Average energy recovery.
▷
Low energy recovery: The vehicle deceler-
ates more slowly, and less energy is re-
turned to the high-voltage battery.
