This will also occur to a certain extent when
the vehicle is rolling to stop when in overrun
mode or travelling downhill.
The higher the charge level of the high-volt-
age battery, the lower the recuperation and
thus also the engine braking effect. No brake
energy recuperation occurs and therefore no
engine braking effect is available once the
high-voltage battery is fully charged →
Brake energy recuperation can be displayed
in the ID. Cockpit or on the Infotainment sys-
tem screen.
Crawling function
The crawling function allows you to drive for-
wards or backwards slowly at a speed of
around 5 km/h (3 mph) without pressing the
accelerator.
The crawling function is automatically activa-
ted when:
— The vehicle's drive system is activated and
the D/B position or reverse gear R is selec-
ted.
The crawling function is deactivated:
— The position switch is in N position and
the electronic parking brake is switched
on.
WARNING
An electric vehicle generates only very low
levels of noise when stationary, driving or
during operation. Other road users, such as
pedestrians and children, may therefore
have difficulty hearing or detecting the ve-
hicle while it is driving. This can result in
accidents and injuries, for example when
driving in traffic-calmed areas, when ma-
noeuvring the vehicle or when reversing.
WARNING
Unintentional vehicle movements can
cause serious injury.
·
If the vehicle's drive system is activated
and the D/B position or reverse gear is
selected, the vehicle must be held with
the foot brake.
WARNING
The higher the charge level of the high-
voltage battery, the lower the engine brak-
ing effect from recuperation, to the point
where no engine braking effect may be
generated at all.
·
Reduce your speed before driving down
a long, steep gradient.
.
·
When driving down a long, steep gradi-
ent, slow the vehicle using the vehicle
brake.
Brake energy recuperation
When the vehicle is braked, and when the ve-
hicle is in overrun mode or driving downhill,
electrical energy is generated via the electric
drive and stored in the high-voltage battery.
The electric drive then acts as a generator
and creates an engine braking effect. This
procedure is known as brake energy recuper-
ation.
The extent of the engine braking effect varies
depending on the position → page 140. If
there is a high level of brake energy recuper-
ation, the brake lights on the vehicle can also
light up. The higher the charge level of the
high-voltage battery, the lower the recupera-
tion and thus the engine braking effect effec-
ted. No brake energy recuperation occurs and
therefore no engine braking effect occurs
when the high-voltage battery is completely
charged. If the vehicle detects that the road
conditions do not allow the wheels to reliably
contact the road surface, recuperation and
thus the engine braking effect will be reduce
automatically. The power meter provides in-
formation about the availability of brake en-
ergy recuperation and the engine braking ef-
fect → page 20.
The vehicle performs brake energy recupera-
tion in different ways depending on the se-
lected position and on the settings in the In-
fotainment system:
