x
Use fast acceleration only if visibility,
weather, road and traffic conditions per-
mit, and other road users are not put at
risk due to the deceleration beha
viour of
the vehicle and driving style.
x Always adjust your driving style in ac-
cordance with the flow of traffic.
x When the TCS is switched off, the drive
wheels may spin, especially if the road
surface is wet, slippery or dirty. This may
result in you no longer being able to
steer or control the vehicle. NOTICE
x If you stop the v
ehicle on a gradient, do
not attempt to stop it from rolling back by
depressing the accelerator when a gear
has been selected. Depress the brake ped-
al to avoid putting an unnecessary load on
the electric drive.

Adaptive Cruise Control
(ACC)
Introduction to the topic
The Adaptive Cruise Control (ACC) main-
tains a constant speed that you ha
ve set.
If the vehicle approaches a vehicle in
front, the ACC automatically adapts the
speed so that a distance you have selec-
ted is maintained.
Does the vehicle have ACC?
The vehicle is equipped with ACC if you can
adjust settings for ACC in the Assist systems
menu in the Infotainment system.
Speed range
You can set the speed between 20 km/h
(15 mph) and the maximum speed.
Driving with ACC
You can override the active ACC system at
any time. Cruise control will be stopped if you
brake. If you accelerate, cruise control will be
interrupted while you are accelerating and
then resumed.
The intervention by the ACC system is less
dynamic when towing a trailer.
Driver intervention prompt
If automatic deceleration by the ACC
system is not sufficient or the system
limits have been reached, the ACC
system will request you to also brake
by a corresponding message on the
instrument cluster. In addition, the
red warning lamp lights up and an
acoustic warning is given. Take over
control of the vehicle and be prepared
to brake.
Radar sensor
ACC detects driving situations using a radar
sensor at the front of the vehicle. The range of the radar sensor is up to approximately
160 m (

around 520 ft). Special driving situations
Please refer to at the start of the chap-
ter on page 151.
Predictiv

e cruise control system
If the vehicle is equipped with the Dynamic
Road Sign Display function and an Infotain-
ment system with navigation, ACC can pre-
dictively adapt the vehicle speed to detected
speed limits and the course of the road ahead

ACC may not react or may react with a delay
or with an unwanted response in the follow-
ing driving situations:

Limits of Front Assist
Please refer to at the start of the chap-
ter on page 159.
F
ront Assist is not available or its
functions are restricted immediately
after the vehicle is started. The indi-
cator lamp lights up in the instrument
cluster display during this time.
Front Assist has physical and system-related
limitations. You should therefore always be
prepared to take full control of the vehicle if
necessary.
Delayed response
If the camera or radar sensor is exposed to
environmental conditions that impair func-
tioning, the system may detect this only after
a certain delay. For this reason, any restric-
tions to functions may be displayed only after
a delay at the start of the journey and when
driving

wise cause accidents or injuries. The sys-
tem is not a substitute f
or the full concen-
tration of the driver.
x Adapt your speed and distance from the
vehicles ahead to suit visibility, weather,
road and traffic conditions.
x Your hands should always be on the
steering wheel so that you can steer at
any time.
x Observe the displays in the exterior mir-
ror housings and on the instrument clus-
ter display and act in accordance with
the requests.
x Always pay attention to what is happen-
ing around the vehicle.
x Never use the lane change system if the
radar sensors are dirty, covered or dam-
aged. These circumstances can impair
the proper functioning of the system.
x It may be hard to see the display in the
wing mirror in direct sunlight. The radar sensors calibrate themselves
once in the first f
ew kilometres after
vehicle delivery and if the sensors are re-
paired. The sensor range may be limited dur-
ing the calibration phase. Driving with the lane change
system
Please refer to at the start of the chap-
ter on page 172. Fig. 113
In the e
xterior mirror housing: visual
displays of the lane change system.
Switching on and off
You can switch the lane change system on
and off in the Assist systems menu of the In-
fotainment system. When the lane change
system is switched on, the yellow indicator
lamp in the exterior mirror housing lights
up once briefly.
This most recent system setting is retained
e

ven after the ignition has been switched off
and on.
Function
When switched on, the lane change system is
active from a speed of around 15 km/h
(9 mph). The lane change system is deactiva-
ted at a vehicle speed below 10 km/h
(6 mph).
In the following driving situations, the yellow
indicator lamp lights up in the housing of
the respectiv

e exterior mirror:

The yellow indicator lamp flashes if a pos-
sible critical situation is detected when you
indicate in the direction of the detected v
ehi-
cle.
The faster another vehicle approaches, the
earlier there is a corresponding display in the
exterior mirror.
Lane change system “Side Assist Plus”
If the vehicle is equipped with a lane keeping
system (Lane Assist) and the system is
switched on, the driver is warned by a correc-
tive steering intervention when changing
lanes during a possible critical situation (in-
formation level, warning level). The steering
intervention also occurs when the turn signal
is activated for the corresponding direction. If
the steering intervention is overridden by the
driver, the steering wheel vibrates to give an
additional warning. For this, steering wheel
vibration must be activated in the Assist sys-
tems menu in the Infotainment system.
Automatic deactivation
The lane change system will switch off auto-
matically if the radar sensors are permanent-
ly covered. This can be caused by a layer of
ice or snow in front of the radar sensor, for
example.
A text message will be shown on the instru-
ment cluster display.
If you use the factory-fitted trailer towing
coupling and have set up the necessary elec-
trical connection, the lane change system
switches off automatically. After you have
disconnected the electrical connection, the
lane change system is switched back on au-
tomatically.
If the trailer towing coupling is not factory-
fitted, you must manually switch off the lane
change system and then switch it back on
again.
Brightness
The brightness of the visual display will
change automatically depending on the am-
bient light levels. You can adjust the basic brightness of the
display in the Assist systems menu in the In-
f
otainment system. The lane change system
is not active during the setting procedure. Troubleshooting
Please refer to at the start of the chap-
ter on page 172. Lane change system fault.
The indicator lamp lights up yellow. The yel-
low central warning lamp also lights up.

Regularly update the appropriate anti-
virus program with the updates or up-
grades pro
vided by the provider.System update
Introduction to the topic
The factory-fitted central control unit sup-
ports the system update function. This allows
the software of almost all control units to be
updated by V

olkswagen AG without the need
to visit a qualified workshop:
If a system update is available for your vehi-
cle, a corresponding message will be dis-
played on the Infotainment system.
System updates are downloaded via the fac-
tory-fitted control unit with eSIM card (OCU)
and are free of charge. Volkswagen pays the
connection costs.
The system update function is only available
in some countries. A measure such as engine tuning to in-
crease perf

ormance or efficiency that
has not been performed by Volkswagen may
be deleted by a system update. Overview
Please refer to at the start of the chap-
ter on page 196.
A

vailability of a system update
The switched-on Infotainment system indi-
cates that a system update is available. A sys-
tem update takes place in two phases:

always using WPA2 encryption. Observe
country-specific requirements.
The necessary data transf
er may be
subject to charges. Due to the poten-
tially high volume of data in use, Volkswagen
recommends using a mobile phone tariff
which includes a data flat rate. For more in-
formation contact your mobile telephone
provider.
Depending on your mobile telephone
tariff, additional costs (such as roam-
ing charges) may be charged for loading and
using online data packages, especially if you
use these services abroad. Setting up a data connection

Driving when the charge level of the high-
v oltage battery is too low can lead to the
vehicle breaking down when in traffic, and
can lead to accidents and serious injuries. The high-voltage battery can only be
charged at charging stations that meet
