Service fluids and consumables
All service fluids and consumables, e.g. tyres, coolant and vehicle batteries, are being constantly
developed. The same applies to toothed belts, engine oils and spark plugs for combustion engines,
for example. For this reason, service fluids and consumables should be replaced at a qualified
workshop. Volkswagen dealerships always have the latest information about any changes.

WARNING
Unsuitable service fluids and consumables, and the incorrect use of these fluids and consumables,
can cause accidents, serious injuries, burns or poisoning.

Various indicator lamps may light up after the 12-volt vehicle battery has been connected and the
ignition is switched on. They will go out when you drive a short distance at a speed of approximately
15 – 20 km/h (10 – 12 mph). If the indicator lamps remain lit up, the vehicle should be checked by a
qualified workshop.
If the 12-volt vehicle battery was disconnected for an extended period, the system may not able to
calculate or correctly display the time when the next service is due ⇒ Instrument cluster . Observe
the maximum permissible service intervals ⇒ Service .
Automatic switch-off for electrical consumers
The intelligent vehicle electrical system management function automatically implements a range of
measures to prevent the 12-volt vehicle battery from discharging under high loads:


power supply to the 12-volt socket and the cigarette lighter may be interrupted temporarily
while the engine is being started.
The vehicle electrics management system cannot always prevent the 12-volt vehicle battery from
being discharged, for example if the ignition is left on over a long period with the engine off or the
side lights or parking lights are left on over a long period of time.

The data of the event data recorder are recorded only if a particular accident-like situation occurs.
No recordings occur under normal driving conditions. Audio or video data from the vehicle interior
or vehicle surroundings are not stored. Personal data such as name, gender, age or accident location
are also not recorded at any time. However, third parties such as law enforcement agencies can use
corresponding means to link the content of the event data recorder with other sources of data and
thus establish a reference to persons as part of an accident investigation.
Special equipment, access to the legally prescribed diagnostic interface (on-board diagnosis) and
switched-on ignition are required in order to read data out of the event data recorder.
Volkswagen will not access, read out or process data from the event data recorder unless the vehicle
owner (or lessee in the case of leasing) grants their permission. Exceptions to this are contractual or
legal provisions.
Due to its legal product monitoring obligations, Volkswagen is entitled to use the data for field
monitoring and also for research purposes and quality improvements. For research purposes,
Volkswagen makes the data available to third parties in anonymous form, in other words without
any reference to the individual vehicle, vehicle owner or lessee.
Reprogramming control units
All data for the control of components are stored in the control units. Some convenience functions,
such as convenience turn signal, single door unlocking and displays, can be reprogrammed using
special workshop equipment. If the convenience functions are reprogrammed, the specifications and
descriptions in this owner's manual will no longer match the original functions. Volkswagen
recommends having any reprogramming entered into the digital service schedule by a Volkswagen
dealership or qualified workshop.
Information about possible reprogramming can be obtained from the Volkswagen dealership.
Convenience and Infotainment functions
Depending on the equipment selected, you can store your own data in the vehicle's Infotainment
functions. This includes, for example:

data for use with a hands-free system or navigation system.


These data can be stored locally in the vehicle or located on a device that you have connected to the
vehicle, e.g. mobile device, USB stick or MP3 player. If these data are stored in the vehicle, you can
