First read and observe the introductoryinformation and safety warnings
The electrolyte level of the 12-volt vehicle battery should be checked regularly in high-mileage
vehicles, in hot countries and in older 12-volt vehicle batteries. The 12-volt vehicle battery is
otherwise maintenance-free.
Vehicles with an auxiliary heater Auxiliary heater and ventilationare fitted with special vehicle
batteries. The electrolyte level of these 12-volt vehicle batteries cannot be checked for technical
reasons. Go to a qualified workshop to have the 12-volt vehicle battery checked.

Charging, replacing, disconnecting and connecting the 12-volt vehicle battery
First read and observe the introductoryinformation and safety warnings
If you suspect that the 12-volt vehicle battery is damaged or faulty, go to a qualified workshop and
have the 12-volt vehicle battery checked.
Charging the 12-volt vehicle battery
The 12-volt vehicle battery should be charged by a qualified workshop, as the technology used in
factory-fitted 12-volt vehicle batteries requires voltage-limited charging
recommends using a Volkswagen dealership for this purpose.
Replacing the 12-volt vehicle battery
The 12-volt vehicle battery has been developed to suit the conditions of its installation location and
has special safety features. If a 12-volt vehicle battery has to be replaced, find out about the
electromagnetic compatibility, size and necessary maintenance, power and safety requirements for
the new 12-volt vehicle battery at a Volkswagen dealership before purchase. The ventilation opening
of the vehicle battery must always be on the negative terminal side: the ventilation opening on the
positive terminal side must always be sealed.
Only maintenance-free vehicle batteries compliant with the standards TL 825 06 and VW 7 50 73
should be used. These standards must be dated October 2014 or later.
Always have the 12-volt vehicle battery replaced by a qualified workshop, as the vehicle electronics
must be adapted as part of the replacement process. Only qualified workshops have the technology
required to carry out this adjustment correctly. Volkswagen recommends that the 12-volt vehicle
battery is replaced by a Volkswagen dealership.
Disconnecting the 12-volt vehicle battery
Please observe the following if the 12-volt vehicle battery has to be disconnected from the electrical
system in the vehicle:

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

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.

Wheels and tyres
Tyre monitoring system
Introduction
This chapter contains information on the followingsubjects:
Tyre Pressure Loss Indicator
Troub
The tyre monitoring system warns the driver when the tyre pressures are too low.
The tyre monitoring system monitors various parameters (for example, rolling circumference) of all
wheels using ABS sensors (indirect measurement).

WARNING
The intelligent tyre monitoring system technology cannot overcome the laws of physics, and
functions only within the limits of the system. Incorrect handling of the wheels and tyres can lead to
a sudden loss of pressure in the tyres, tread separation and even tyre blow-out.

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:

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.
