Suitable earth connection: preferably the jump lead connection point (earth connection), a
solid metal part which is securely bolted onto the cylinder block, or the cylinder block itself.
The discharged 12-volt vehicle battery must be properly connected to the vehicle's electrical system.
The vehicles must not touch. Otherwise electricity could flow as soon as the positive terminals are
connected.
Ensure that the battery clamps have good metal-to-metal contact with the battery terminals.
If the engine does not start immediately, switch off the starter after about 10 seconds and try again
after about a minute.
If the engine still does not start, seek expert assistance.
Attaching the jump leads
The jump leads should be connected only in the order A – B – C – D⇒ Fig. 177 .
The black jump lead should never be connected to the negative terminal (–) on the 12-volt vehicle
battery. Connecting the lead to the negative terminal can cause incorrect condition evaluation of the
12-volt vehicle battery in the vehicle electronics.

NOTICE
When filling or changing service fluids, please ensure that the correct service fluids are filled through
the correct openings. The use of incorrect service fluids could result in serious malfunctions and
engine damage.
Service fluids that leak from the vehicle are harmful to the environment. For this reason, you should
regularly check the ground underneath your vehicle. If there are spots of oil or other fluids on the
ground, the vehicle should be inspected by a qualified workshop. Any spilt service fluids must be
disposed of properly.

12-volt vehicle battery
Introduction
This chapter contains information on the followingsubjects:
⇒ Checking the electrolyte level of the 12-volt vehicle battery
⇒ Charging, replacing, disconnecting and connecting the 12-volt vehicle battery
⇒ Troubleshooting
The 12-volt vehicle battery is a component of the electrical system and serves to supply power in the
vehicle.
Page 385 of 502

Do not work on the electrical system unless you are familiar with the task, aware of the general
safety procedures and have the correct equipment, service fluids and suitable tools. Serious injuries
can be caused by carrying out work incorrectly ⇒ . All work should be carried out by a qualified
workshop. Volkswagen recommends using a Volkswagen dealership for this purpose.
Information for warning and indicator lamps lit up can be found in the troubleshooting at the end of
the chapter ⇒ Troubleshooting .
Location of the 12-volt vehicle battery
The 12-volt vehicle battery is located in the engine compartment.
Explanation of the warnings on the 12-volt vehicle battery
Always wear eye protection!Electrolyte is very corrosive and caustic. Always wear
protective gloves and eye protection!Fire, sparks, naked lights and smoking are prohibited!
A highly explosive mixture of gases is given off when the 12-volt vehicle battery is charging!
Always keep children away from electrolyte and the 12-volt vehicle battery!Always
observe the owner's manual!
WARNING
Any work on the 12-volt vehicle battery and the electrical system can cause serious chemical burns,
fire or electric shocks. Always read and observe the following warnings and safety information
before carrying out any kind of work:
any work on the 12-volt
vehicle battery and also disconnect the negative cable from the 12-volt vehicle battery.

Charging, replacing, disconnecting and connecting the 12-volt vehicle battery
First read and observe the introductoryinformation and safety warnings⇒Introduction
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 ⇒ . Volkswagen
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:
-theft

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.
