Identifier of producing plant and
specifications of the tyre manufacturer
for size and characteristics.
2213 Manufacturing date: 22nd week in

Information for the end user concerning comparative values for specified basic tyres
(standardised test procedure) ⇒ Customer information :
④ TREADWEAR 280 Relative life expectancy for the tyre, with
reference to a US-specific standard test. Tyres
with the specification 280 wear 2.8 times more
slowly than standard tyres which have a
treadwear value of 100. The performance of tyres
is determined by how they are used and can
deviate significantly from standard values due to
driving style, maintenance, road surface and
climatic conditions.
⑤ TRACTION AA Wet braking response of the tyre (AA, A, B or C).
The wet braking response is tested under
controlled conditions on certified test tracks.
Tyres marked C have a low traction performance.
The traction value assigned to the tyres is based
on linear traction tests and does not include
acceleration, lateral stability, aquaplaning or
traction under maximum load.
⑥ TEMPERATURE A Temperature stability of the tyre at higher test
bench speeds (A, B or C). A and B tyres exceed
legal requirements. The temperature evaluation is
based on tyres with correct pressure and does not
allow for excess pressure. Excessive speed,
incorrect pressure or excess pressure can cause
heat build-up or tyre damage. This applies to one
or a combination of these factors.

Service work and digital service schedule
The vehicle data attached to the inside cover of this owner's manual help ensure that you can have
the correct Volkswagen Genuine Parts® installed in your vehicle whenever required. It also
determines which type of service applies to your vehicle.
The vehicle data sticker confirms when the vehicle was first registered or delivered, when the pre-
delivery inspection was carried out, and thus the date from which your vehicle is covered by our
warranty.
Storing the service operations performed (digital service schedule)
Each service record is stored by your Volkswagen dealership and qualified workshop in a central
system. This transparent documentation of the service history allows the service operations
performed to be reproduced at any time. Each time you have your vehicle serviced, Volkswagen
recommends asking for a printed service record, which contains all service work stored in the
system.
With every service, the printout of the previous service record is replaced by a current printout.
The digital service schedule is not available in some markets. In this case, your Volkswagen
dealership will inform you about the documentation process for service work.
Service work
The following information is documented in the digital service schedule by your Volkswagen
dealership or qualified workshop:

Scope of service
The scope of service includes all maintenance work that is necessary in order to keep your vehicle
roadworthy (depending on the operating conditions and vehicle equipment, e.g. engine, gearbox or
service fluids). The maintenance work is divided into inspection work and servicing work. You can
find out what work is required in detail for your vehicle:



Inspection work
Electrics
-volt vehicle battery: check and replace if necessary.




Engine/gearbox


tem: check.
-belt: check.

Please note that the validity of the Volkswagen LongLife mobility guarantee may differ depending on
the country in which the vehicle was sold. Please ask your Volkswagen dealership for further
information.
The selling Volkswagen dealership will issue a comprehensive LongLife mobility guarantee for every
new vehicle which applies from the time of delivery until the first due inspection. If you purchase
your new vehicle directly from Volkswagen AG, Volkswagen AG will issue the LongLife mobility
guarantee from the time of delivery until the first due inspection.
Your Volkswagen dealership will extend the LongLife mobility guarantee until the following
inspection when the due inspection is carried out by the dealership. The service costs include the
entire guarantee package.
The comprehensive LongLife mobility guarantee includes the following services:
If your vehicle can no longer be driven due to a technical defect1), corresponding assistance will be
provided in the case of breakdown or accident. The LongLife mobility guarantee provides with you
protection and mobility.
The inspection is not only about car maintenance - it also ensures that your car remains roadworthy
and in perfect working order. For this reason, servicing should be carried out regularly in accordance
with the manufacturer's specifications.
Your entitlement to the LongLife mobility guarantee is documented in the digital service schedule
each time your car is serviced. A full service history shows that your car has been professionally
maintained and cared for.
1) A vehicle which can no longer be driven is a vehicle which cannot reach a workshop under its own
power.
Data storage and services
Your vehicle is fitted with electronic control units. Some of these are required to make sure your
vehicle remains safe while others provide support while driving (driver assist systems). Furthermore,
your vehicle is equipped with convenience and Infotainment functions, which are also made possible
using electronic control units.
Electronic control units contain data memories which can store information regarding the vehicle
status, component load levels, servicing requirements, technical events and faults on a temporary or
permanent basis. This information generally documents the status of a component, a module, a
system or the environment, e.g.:
. filling levels, tyre pressure, battery status.
deceleration, lateral acceleration, display of fastened seat belts.
tem components, e.g. lights, brakes.

stability control systems.

e.g. temperature, rain.
As well as performing the actual control functions, these data are also used to detect and rectify
faults and help Volkswagen to improve vehicle functions. The majority of these data are temporary
and are only processed within the vehicle itself. Only a very small amount of data is stored in the
event memories or possibly on the vehicle key.
Reading out the vehicle's event memory
There is a diagnostic interface in the vehicle interior for reading out the event memories (on-board
diagnosis) ⇒ .
If you have service work performed on your vehicle, the technical data can be read out of the vehicle
together with the vehicle identification number by service employees, e.g. workshops, or third
parties such as breakdown services. Service work includes, for example, repairs, maintenance,
warranty work or quality assurance measures. The service workshop or third party collects,
processes and uses the data. The data document the vehicle's technical status, help in
troubleshooting and in improving quality and may be sent to Volkswagen in some cases.
Furthermore, the manufacturer is subject to legal product safety requirements. To make sure it
complies with these requirements, the manufacturer requires technical data from the vehicles.
Event memories in the vehicle can be reset by a service workshop as part of repair or service work.
The event memory should be read out and reset only by a qualified workshop. Additional
information on the stored data is available from the qualified workshop.
After a fault has been rectified, the information in the memory relating to the fault is deleted. Other
memory content is overwritten on an ongoing basis.
Event data recorder
This vehicle is equipped with an event data recorder. The main task of an event data recorder is to
record data in particular accident scenarios or accident-like situations, e.g. in the event of airbags
being triggered or a collision with an obstacle on the road. These data help in analysis of how a
vehicle system behaved in these situations. The event data recorder records data relating to driving
dynamics and the restraint system for a short period of 10 seconds or less. This information includes,
for example:

of the driver and front passenger were fastened.


These data help to obtain a better understanding of the circumstances in the situations where
accidents and injuries have occurred.
Data from driver assist systems are also recorded. In addition to information about whether the
systems were switched on or off, available only to a restricted extent or inactive, it is also possible to
determine whether these functions steered, accelerated or braked the vehicle in the above-
described situations. Depending on the vehicle equipment, these systems include the following:
