Regenerative braking

In deceleration mode and when braking, the high-
voltage battery is charged through regenerative
braking and the electric motor then operates as a
generator.
Regenerative braking in deceleration mode:
During regenerative braking in deceleration
mode, the vehicle is braked in a similar way to a
vehicle with combustion engine.
The level of regenerative braking in deceleration
mode can be adjusted using the steering wheel
shift paddles as a special equipment option:
Stage 0: No regenerative braking, the vehicle
retains the maximum possible amount of
kinetic energy.
Stage 1: Normal driving, default setting (stan-
dard)
Stage 2: For sporty driving. The brake pedal has
to be used less because the level of decel-
eration is higher than in stage 1.
The level of regenerative braking is indicated on
the right additional instrument
