Charging, Replacing, Disconnecting or Connecting the 12-volt Vehicle Battery
If you suspect that the 12- volt vehicle battery is damaged or faulty, go to a suitably qualified workshop and have the 12- volt vehicle battery checked. Volkswagen recommends contact with an ID. UNYX Service Center.
Charging the 12-volt vehicle battery
The 12- volt vehicle battery should be charged by a suitably qualified workshop, as the technology used in factory- fitted 12- volt vehicle batteries requires voltage- limited charging. Volkswagen recommends contact with an ID. UNYX Service Center.
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, the replacement part must be installed by a workshop qualified to do this. For component information on size and the required maintenance, capacity and safety features, please contact a suitably qualified workshop, which must have the necessary technical documentation and equipment. Volkswagen recommends contact with an ID. UNYX Service Center. The ventilation opening of the 12- volt 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 12- volt 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.
The 12- volt vehicle battery must always be replaced by a workshop qualified to do this, as the vehicle electronics must be adapted as part of the replacement process. In addition, the battery parameters for functional safety were determined only with the original equipment battery. Only suitably qualified workshops have the technology required to carry out this adjustment and also the correct replacement batteries.
Disconnecting the 12-volt vehicle battery
Please note the following if the 12- volt vehicle battery needs to be disconnected:
- Switch all electrical consumers off.
- First disconnect the negative cable and then the positive cable.
Connecting the 12-volt vehicle battery
Please note the following if the 12- volt vehicle battery needs to be connected:
- Switch all electrical consumers off.
- First reconnect the positive cable and then the negative cable.
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 if you drive a short distance at a speed of around 15\mathrm{km / h} to 20\mathrm{km / h} . If the indicator lamps stay lit, the vehicle should be checked by a suitably qualified workshop. Volkswagen recommends contact with an ID. UNYX Service Center.
Checking the Electrolyte Level of the 12-volt Vehicle Battery
Checking the Electrolyte Level of the 12- volt Vehicle BatteryThe electrolyte level of the 12- volt vehicle battery should be checked regularly in high- mileage vehicles, in hot regions and in older 12- volt vehicle batteries. The 12- volt vehicle battery is otherwise maintenance- free.
Location of 12-volt vehicle battery
The 12- volt vehicle battery is located in the bonnet space.
Checking the electrolyte level
Checking the electrolyte levelThe main fuse box on the 12- volt vehicle battery might needs to be removed to check the electrolyte level of the 12- volt vehicle battery. An additional tool that is not included in the vehicle toolkit is required for this purpose.
Always have the electrolyte level of the 12- volt vehicle battery checked by a suitably qualified workshop. Volkswagen recommends contact with an ID. UNYX Service Center.
