First read and observe the introductory information and safety warnings

Charging the battery

The vehicle battery should be charged by a qualified workshop, as the technology used in factory-fitted batteries requires voltage-limited charging  . Volkswagen recommends using a Volkswagen dealership for this purpose.

Replacing a vehicle battery

The battery has been developed to suit the conditions of its location and has special safety features. If a vehicle battery has to be replaced, discuss the electromagnetic compatibility, size and necessary servicing, output and safety requirements for the new vehicle battery with a Volkswagen dealership before purchase. Volkswagen recommends that the vehicle battery is changed by a Volkswagen dealership.

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 April 2008 or later.

Vehicles with a start/stop system (  ) are fitted with special vehicle batteries. These vehicle batteries may only be replaced by a vehicle battery with the same specifications.

Disconnecting the vehicle battery

Please note the following if the vehicle battery has to be disconnected from the electrical system in the vehicle:

Connecting the vehicle battery

Various indicator lamps may light up after the vehicle battery has been connected and the ignition is switched on. They will go out if you drive a short distance at a speed of 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 vehicle battery was disconnected for long periods, the system may not able to calculate or correctly display the time when the next service is due   .

Vehicles with Keyless Access (  ): if the ignition cannot be switched on after connecting the vehicle battery, lock and unlock the vehicle from the outside. Then try to start the ignition again. Please contact an expert if the ignition cannot be switched on.

Automatic switch-off for electrical consumers

An intelligent vehicle electrical system can prevent the vehicle battery from draining. When high demands are placed on the vehicle battery various measure are automatically implemented:

The vehicle electrical system cannot always prevent the vehicle battery from discharging. For example when the ignition is switched on for an extended period with the engine off, or when the side or parking lights are on when the vehicle is parked for an extended period.

What can cause the vehicle battery to discharge?

WARNING

Incorrectly attaching the battery and using incorrect vehicle batteries can cause short circuits, fire and serious injuries.

WARNING

A highly explosive mixture of gases is given off when the vehicle battery is being charged.

NOTICE

Dispose of the vehicle battery as required by legislation. Batteries may contain toxic substances such as sulphuric acid and lead.

Electrolyte can pollute the environment. Clean up any service fluid leakages and dispose of them properly.
