ectric drive system functions. Delivery of power from the electric engine
The maximum tor
que of the el

ectric engine is
available immediately after pressing the ac-
celerator pedal.
Brake energy recuperation (charging)
When braking the vehicle, electric power is
generated through the electric engine and
stored in the high-voltage battery

br ak e ener
gy recuperation. Fig. 135
On the instrument panel display: indi-
cation of r ecuperation l

evels.The brake energy recuperation can generate
a br
aking eff
ect. This br

aking effect depends
on the selected driving programme and the
level of charge of the high-voltage battery. When braking the vehicle and when the vehi-
cle mov

es by inertia or travels downhill in the
deceleration phase, electric power is gener-
ated by the electric engine and stored in the
high-voltage battery. The electric engine
then operates as an alternator and produces
a engine brake effect. This process is called
brake energy recuperation.
The status of the recuperation is indicated in
the power display of the instrument panel

Drive system and driving
Indication that the drive system is connec-
t ed
The el ectric engine does not gener
ate no-
ticeable noises neither when connecting the
drive system nor when it is running. Therefore,
it is not possible to recognise whether the
drive system is running based on the engine
noises. Instead, you can recognised that the
drive system is connected by the following
characteristics:

Drive system and driving
 - Neutr
al
The el ectric driv
e system is in the neutral po-
sition. No movement is transmitted to the
wheels and the braking effect of the electric
engine does not occur.

Driving
Note
If the selector lever is left for a long time in
a position other than P with the ignition off,
the 12-v olt batt
ery may discharge.Driving with an automatic gearbox
Driving down slopes
The steeper the sl
ope

, the higher the selected
brake energy recuperation level will have to
be. A high recuperation level increases the
braking effect of the electric engine. Never let
the vehicle roll downhill with the selector lev-
er in the neutral position N.

Saf et
y warnings for performing
works in the engine compartment The engine compartment of the vehicle is a
dangerous ar
ea. Y

ou should only perform
works in the engine compartment if you have
good knowledge of the necessary operations
and the general safety measures, and if you
have adequate tools, means and operating
fluids. Works performed inadequately, could
lead to serious injuries

Verification and replacement
If for weather reasons further protection is
necessary, the pr oportion of additiv
e may be
incr
eased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
additive G12evo for optimal protection
against corrosion. Mixing G12evo with G13
(TL-VW 774 J), G12 plus-plus (TL-VW 774 G),
G12 plus (TL-VW 774 F), G12 (red) or G11
(green blue) engine coolants decreases pro-
tection again corrosion and should be avoi-
ded. WARNING
If there is not enough anti-freeze in the
coolant syst em, the engine may f

ail lead-
ing to serious damage.

Verification and replacement
from discharging. For example, if the ignition is
k ept on f
or a l
ong time with the engine stop-
ped or if the parking or side light is left on for
a long time.
