electrical system and to the high-voltage
battery.
Driving with an open boot lid
Driving with an open boot lid is particularly
dangerous. All objects and the open boot lid
must be secured properly and suitable meas-
ures taken.
Driving with an open boot lid increases the
air resistance of the v
ehicle and thus also the
energy consumption of the electric drive.
This considerably reduces the possible range
of the vehicle. Volkswagen does not recom-
mend driving with the boot lid open due to
the resulting reduction in range. NOTICE
The vehicle height, and possibly the length,
are diff
erent when the boot lid is open. Driving through water on
roads
Please f

ollow these rules to help prevent
damage to your vehicle when driving through
water, for example if the road is flooded:

This will also occur to a certain extent when
the v
ehicle 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

Position engaged and ECO assistance deac-
tiv
ated: no brake energy recuperation.
Position engaged and ECO assistance acti-
v

ated: automatic brake energy recuperation.
The energy recovery level is selected auto-
matically depending on the navigation data
and traffic situation.
Position engaged: high brake energy recu-
peration
The v

ehicle also performs recuperation when
the brake pedal is pressed.
Eco assistance
The ECO assistance function helps the driver
to use the engine braking effect of the vehi-
cle efficiently. It selects the energy recovery
level depending on the navigation data and
traffic situation.
The ECO assistance function can be switched
on and off in the vehicle settings in the Info-
tainment system.
Driving down hills
When driving down hills, you should drive in
position B if possible.
Never allow the vehicle to roll down moun-
tains or hills in the neutral position N. Troubleshooting
Deactivation of the drive is imminent
The charge level of the high-voltage battery
is too low.
The indicator lamp lights up during v

ehicle
operation.
The indicator lamp lights up red.
A text message is shown on the ID. Cockpit

Data transfer
CybersecurityWhat is cybersecurity?
Cybersecurity comprises measures to reduce
the risk of unauthorised access by malware or
an Internet attack on v
ehicle functions, data
and control units.
What are connectivity components?
Control units for data transmission, interfa-
ces, and media and diagnostic connections
are connectivity components, via which in-
formation and data can be exchanged be-
tween the vehicle and external devices or the
Internet. The connectivity components that
are not included in all vehicles are, in particu-
lar:

Grey globe: it is not currently possi-
ble to establish a connection to the
Internet or a connection is currently
being set up. Signal strength display of the
eSIM with a
vailable mobile com-
munication standard.
Legally required services can influence the
status display for data transmission inde-
pendently of activated offline mode.
Even if offline mode is activated, on-
line mode can be activated briefly by
safety-relevant and legally required services.
No We Connect Start services are activated
and no data of these services is transmitted
during this time. Offline mode will be reacti-
vated and the eSIM deactivated again after
successful transfer of the safety-relevant or
legally required data. Effects on online vehicle func-
tions
If data transf

er is restricted, the following
online function cannot be executed, for ex-
ample.

x
Always check after installation to make
sure that the retaining hooks of the par-
tition are correctly engaged.
x Additionally secure all objects in the lug-
gage compartment e
ven when the parti-
tion is installed.
x While the vehicle is moving, no passen-
gers may travel behind the fitted parti-
tion. NOTICE
If the partition is not secured at the mount-
ing points pro
vided for this purpose, this may
result in damage.
x Always secure the partition only to the
designated mounting points. Fitting and removing the par-
tition behind the front seats
Fig. 130
P
artition installed behind the front
seats.
The fitted partition can help to prevent ob-
jects from being flung from the luggage
compartment into the passenger compart-
ment, e.g. when braking.
The partition can be optionally installed be-
hind the rear bench seat

WARNING
Elastic tensioning straps must be stretched
to attach to the fastening rings. The hooks
attached to them can cause serious injuries.
x Always protect eyes and face from injury
when attaching elastic tensioning straps.
x Always hold elastic tensioning straps se-
curely when fastening so that they can-
not slip off and rebound.
x Always fasten the elastic tensioning
straps first to the fastening rings in the
front area of the luggage compartment,
then pull them towards the loading sill
and fasten them to the fastening rings
there. If the tension straps slip off
, they
will snap away from the body. Suitable lashing, retaining or securing
straps and luggage securing systems
are a

vailable from qualified workshops.
Volkswagen recommends using a Volkswagen
dealership for this purpose. Luggage net
Fig. 132
In the luggage compartment: luggage
net fitted flat.
The luggage net can help to pre

vent light
items of cargo from sliding around in the lug-
gage compartment. The luggage net also has
a built-in pocket with a zip that can hold
smaller items. .
The luggage net zip must face upwards.

x
A void abrupt and sudden driving and
braking manoeuvres.
x Always adapt your speed and driving
style to suit visibility, weather, road and
traffic conditions. NOTICE
Securing a roof carrier of any kind to a vehicle
that is not appro
ved for use with a roof carri-
er may lead to severe damage to the vehicle. Driving with a fitted roof carrier in-
creases the air resistance of the v

ehi-
cle and thus also the energy consumption of
the electric drive. This reduces the possible
range of the vehicle considerably. This ap-
plies to all roof carriers and the objects trans-
ported on them, e.g. bicycles and skis. Securing roof carriers
Please refer to and at the start of
the chapter on page 262.
Special roof carriers must be used to trans-
port luggage, bicycles, skis, surfboards or
boats saf
