Compensate for the reduced engine braking
effect by pressing the brake pedal
accordingly, as required.
Using the steering wheel paddle shifters,
you can increase or decrease the
recuperation in overrun phases.
Recuperation means that energy is
recovered while driving - the electric
motor functions as a generator. The kinetic
energy of the vehicle is converted into
electric power and stored in the high-
voltage battery. The more the recuperation
increases, the more the vehicle will be
decelerated.
In overrun phases, there are three levels of
recuperation:
R
no recuperation (level 0, coasting)
R
mid-level recuperation (level 1)
R
high-level recuperation (level 2)
The amount of recuperation in overrun
mode is displayed in the power gauge
(Y page 79).
When you switch on the ignition, level 1 is
automatically preset.
X
Decrease recuperation: Pull left
steering wheel paddle shifter :.
X
Increase recuperation: Pull right
steering wheel paddle shifter ;.
Use the different levels 0 to 2 for
conditions as described below:
Level 0 Driving without frequent
breaking. No sharp bends on
the road ahead.
Maximum kinetic energy
remains for the vehicle.
Level 1 Normal driving, standard
setting.
Level 2 Sporty driving.
The break pedal has to be
depressed less often, as the
deceleration due to
recuperation is higher than
in level 1.
The energy efficiency is
substantially higher than if
the vehicle is decelerated by
depressing the brake pedal.
At levels 1and 2the vehicle can be
steplessly decelerated by depressing the
brake pedal.
i
Under certain circumstances, in
overrun phases recuperation does not
work as described above. This may be e.g
the case if the high-voltage battery is
already fully charged or has not reached
operating temperature.

Driving on uphill grades

WARNING
The hill-start assist system is not
designed to function as a parking brake and
does not prevent the vehicle from moving
when parked on an incline.
Always engage the parking brake in
addition to shifting to park position P.
