Characteristics when
releasing the accelerator
pedal during the journe y:
R The electric mo tor is operated as a alternator
when in overrun mode and during braking.
R The high-voltage bat tery isch arging.
No tes on elect ric mode:
R Vehicles with hybrid systems generate signi/-
cant lyless noise when stationary and when
being driven than vehicles with combustion
engines.
R When driving in elect ric mode, theve hicle may
not be heard by otherroad users due tothe
signi/cantly reduced noise generated.
It is forth is reason that theve hicle is equip-
ped with a sound generator, which ser ves as
an acoustic vehicle warning system (A VAS).
R If not all of theve hicle conditions for electric
mode are met, then the combustion engine is
switched on.

No tes on the acoustic vehicle warning system:
R The sound generator generates speed-depend-

fo rw ard or backing up at a speed of up to
around 30 km/h.
R This helps other road users, particular ly

better.

Depending on the selected recuperation le vel,the
electric mo tor is operated as an alternator when
in ove rrun mode and during braking in order to
ch arge the high-voltage battery while driving. As
soon as youre lease the accelerator pedal when
th eve hicle is in motion, recuperation in overrun
mode is initiated.
The higher there cuperation, the more sharply the
ve hicle is braked when coasting and the more
electrical energy is fed into the high-voltage bat-
te ry.
The rege nerative brake system has thefo llowing
ch aracteristics:
R supports braking with elect ronically cont rolled
brake force boosting
R con verts th e kinetic energy of theve hicle into
elect ric energy %
Ifyo u brake hard, the mechanical brake is
also used. This means that the maximum
re cuperative energy cann otbe reco vered. The
more you drive and brake in an anticipatory
manner, the more e1cient lyenergy can be
re cuperated.

The braking e.ect of the electric mo tor during

tions:
R when the high-voltage battery charge level
increases
R ifth e high-voltage battery is not yet at a nor-

In these cases, the desired deceleration is set by
th e brake control system. Also brake with the
