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. WARNING
Driving with an unlocked or open boot lid
can cause serious injuries.
x Always driv

e with the boot lid closed.
x Always stow all items in the luggage
compartment securely. Loose objects
can fall out of the luggage compartment
and injure other road users.
x Always drive carefully and ensure that
you think ahead.
x Avoid any abrupt or sudden driving and
braking manoeuvres as this can cause
the open boot lid to move unpredictably.
x Any objects protruding from the luggage
compartment must be marked to ensure
that they are visible to other road users.
Observe the legal requirements.
x Any objects protruding from the luggage
compartment must never be held in po-
sition by the boot lid.
x If it is necessary to drive with the boot
lid open, all luggage racks and cargo
stowed on the rack must be removed
from the boot lid. 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. WARNING
The higher the charge level of the high-
v
oltage battery, the lower the engine brak-
ing effect, to the point where no engine
braking effect may be generated at all. This
puts more strain on the vehicle brake.
x Never fully charge the high-voltage bat-
tery at high elevations, e.g. at the top of
a pass, in order to facilitate a braking ef-
fect by means of recuperation when de-
scending.
x Reduce your speed before driving down
a long, steep gradient.
x When driving down a long, steep gradi-
ent, slow the vehicle using the vehicle
brake. 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

WARNING
Driving without the brake servo or with re-
stricted brake serv o function can consider-
ably increase the braking distance and
cause accidents and serious injuries.
x Never deactivate the electric drive or
switch off the ignition as long as the ve-
hicle is still moving.
x If the brake servo does not function or
the vehicle is being towed, the brake
pedal will have to be depressed more
forcefully as the braking distance will be
increased due to the lack of assistance
for the brake system. Brake blending
The brake blending function regulates be-
tween the braking action of the electric driv

e
motor during energy recovery (brake energy
recuperation) and mechanical braking by the
driver. Switching ESC Sport on and
off
Switching ESC Sport on and off
The ESC Sport function interv

enes later than
the normal ESC to stabilise the vehicle.
With some equipment levels, ESC Sport can
be switched on and off.

Practical equipment
Stowage areas Introduction to the topic
WARNING
Loose objects may be flung through the ve-
hicle interior in the e vent of a sudden driv-
ing or braking manoeuvre. This can cause
serious injury and can also lead to loss of
control of the vehicle.
x Stow objects only in closed stowage
compartments.
x Always keep stowage compartments
closed while the vehicle is in motion.
x The coat hooks in the vehicle should on-
ly be used for lightweight clothing
weighing max. 2.5 kg (approx. 5.5 lbs).
Never leave any heavy, hard or sharp ob-
jects in the pockets. WARNING
If the glove box is left open, this can in-
crease the risk of serious injury in the e
vent
of an accident or during sudden braking or
driving manoeuvres.
x Always keep the glove box closed while
the vehicle is in motion. WARNING
Any lighters in the vehicle could be dam-
aged or accidentally lit. This could lead to
serious burns and other injuries.
x Bef

ore closing stowage areas or com-
partments always make sure that there
is no lighter in the way.
x Never stow lighters in stowage areas or
compartments or on other surfaces in
the vehicle. High surface temperatures,
especially in summer, may cause lighters
to self-ignite. WARNING
Incorrect use of the drink holders can cause
injury.
x Ne

ver place hot drinks in a drink holder.
Hot drinks in a drink holder could be
spilled and cause scalding in any sudden
braking manoeuvre or accident.
x Make sure that only drinks of the appro-
priate size are placed in the drink holder.
Drinks must always be stored securely in
the drink holder. WARNING
Closed drink bottles can explode in the ve-
hicle in e
xtreme heat or burst in extremely
cold temperatures.
x Never leave closed drink bottles in an
extremely hot or extremely cold vehicle
for extended periods. NOTICE
x Do not stow any temperature-sensitiv
e
objects, food or medicines inside the vehi-
cle. Hot and cold temperatures could dam-
age them or render them unusable.
x Objects stored in the vehicle that are
made from transparent materials, such as
transparent suction cups on the windows,
can concentrate the sun

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. Signal strength display of the eSIM
The signal strength display shows in online
mode whether the eSIM of the factory-instal-
led OCU can transmit and receiv

e data at the
current vehicle location and how good the
signal strength is.
The more bars that are highlighted in colour,
the stronger the signal and the larger the
amount of data that can be transferred. Ex-
ample: one or two highlighted bars indicate
a low signal strength. There may be restric-
tions in this case for the high data transfer
rates for streaming services.
The signal strength display functions inde-
pendently of the mobile communication
standard display.
There is no signal strength display in offline
mode and in the event of faults in the eSIM.
The signal strength display of the eSIM
does not show the signal strength of
a mobile device paired with the Infotainment
system.
The signal strength display of the eSIM does
not show whether a Wi-Fi device connected
to the Infotainment system is connected to
the Internet. Effects on online vehicle func-
tions
