2015 VOLKSWAGEN E GOLF battery

should always be replaced by a qualified technician, since the vehicle's onboard electrical system management has to be reset after replacing the battery. Only a qualified service facility is able to perform this necessary adjustment. Therefore, Volkswagen recommends to always have the 12 volt vehicle battery replaced by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Only use maintenance-free vehicle batteries meeting standards TL 825 06 and VW 7 50 73. These standards must date from July 2012 or later.
Disconnecting the 12 Volt vehicle battery
If the battery must be disconnected from the vehicle's electrical system, note the following:
x Switch off all electrical systems and devices and the ignition.
x Unlock the vehicle before disconnecting the battery; otherwise the alarm system will go off.
x First disconnect the negative cable (-) and then the positive cable (+) ⇒ .
Connecting the 12 volt vehicle battery
x Prior to reconnecting the battery, switch off all electrical systems and devices and the ignition.
x Connect the positive cable (+) first and then the negative cable (-) ⇒ .
After the battery is connected and the ignition is switched on, different indicator lights may light up. They should go out after you drive a short distance at 10–12 mph (15–20 km/h). If the indicator lights do not go out, contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility and have the vehicle checked.
If the battery was disconnected for a long time, the next scheduled service may not be correctly calcu-
lated and displayed ⇒  Instrument cluster. The maximum permissible service and maintenance inter-
vals are shown in the ⇒ Booklet Warranty and Maintenance.
Vehicles with Keyless Access
If the ignition will not start after reconnecting the vehicle battery, lock the vehicle from the outside and
unlock it again ⇒  Unlocking or locking the vehicle with Keyless Access. Then try to start the ignition again. If the ignition cannot be switched on, contact an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop for assistance.
Automatic electrical load deactivation
If the vehicle battery drain is high, the intelligent onboard electrical system management automatically takes steps to help prevent battery drain.
x The idle speed is increased so that the alternator provides more power.
x The power to devices that consume a lot of electricity is cut back or switched off completely.
The onboard electrical system management cannot always keep the battery from being drained. For example, the battery will drain if the electric motor is not activated, but the ignition is switched on or the parking lights are left on for a long time when parked.
What drains the vehicle battery?
x Long periods when the electric motor is not activated, especially when the ignition is on.
x Using electrical systems or devices when the electric motor is switched off.
x Leaving the vehicle unlocked for several days when not in use.
x The selector lever is left for a long period of time in any position other than Park (P) when the
ignition is switched off ⇒  Selector lever.

WARNING
Failure to use the proper battery with proper mounting and connections may cause short circuits, fires, and serious personal injuries.
x Always use only maintenance-free or cycle-free, leak-proof batteries with the same speci-fications and dimensions as the original equipment battery. Specifications are listed on the battery housing.
WARNING
When the vehicle battery is charged, it produces highly explosive hydrogen gas.
x Charge vehicle batteries only in well-ventilated areas.
x Never charge a frozen or thawed battery. A dead battery can freeze at temperatures around +32 °F (0 °C).
x You must replace the vehicle battery if it was frozen.
x Incorrectly connected cables can cause a short-circuit. First connect the positive cable (+) and then the negative cable (-).
NOTICE
x Never disconnect the vehicle battery or connect 2 vehicle batteries to each other when the ignition is switched on or the electric motor is activated. Doing this may damage the electrical system or electronic components.
x Never use a vehicle battery that does not meet the specifications for the vehicle battery for your vehicle. Using the wrong battery can damage the electrical system or electronic compo-nents and cause electrical malfunctions.
x Never connect power generating equipment, such as a solar panel or battery charger, to the 12 Volt socket in order to charge the vehicle battery. This can damage the vehicle's electrical system.
Dispose of the vehicle battery according to regulations. Vehicle batteries contain poisonous substances such as sulfuric acid and lead.
Battery acid can pollute the environment. Catch leaking operating fluids and dispose of them properly.

x When being towed.
Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to alert other motorists and cyclists to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common sense.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot. They can cause fires and serious personal injury.
x Never park where parts of the hot exhaust system or catalytic converter could ignite flammable materials, such as dry grass, brush, leaves, spilled fuel, etc.
NOTICE
To help prevent damage to the vehicle if you should have to push it a short distance by hand, never push against spoilers, lights, body panels, windows, or similar parts. Concentrating force on these parts of the vehicle can cause expensive damage that may not always be obvi-ous right away.
The vehicle battery will be drained if the emergency flashers are on for a long time – even if the ignition is switched off.

WARNING
Improper use of jumper cables when jump-starting a vehicle with a dead battery can cause the battery to explode, leading to serious personal injury. To help reduce the risk of battery explosion:
x All work on the batteries or the electrical system in your vehicle can cause serious acid burns, fires, or electrical shocks. Always read and heed the following WARNINGS and safety
precautions before working on the batteries or the electrical system ⇒  12 Volt vehicle bat-tery.
x Always make sure that the battery providing starting assistance (the booster battery) has the same voltage as the dead battery (12 V) and about the same amperage capacity (see bat-tery label).
x Never jump-start a vehicle with a thawed or frozen vehicle battery. The battery can ex-plode. A dead battery can freeze at temperatures around +32 °F (0 °C).
x A battery that is frozen or was frozen, but has since thawed, must be replaced.
x When the vehicle battery is jump-started, it gives off hydrogen gas, which is highly explo-sive! Always keep fire, sparks, open flame, and smoking materials far away from vehicle bat-teries. Never use a mobile telephone while connecting or disconnecting jumper cables.
x Jump-start batteries only in well-ventilated areas. Batteries give off highly explosive hy-drogen gas during jump-starting.
x Always route the jumper cables so that they cannot get caught in any moving parts in the electric motor compartment.
x Never short out the battery terminals by connecting the positive (+) and negative (-) termi-nals with each other.
x Never connect the negative cable from the other vehicle directly to the negative terminal of the dead battery, as this may cause the hydrogen gas given off by the dead battery to ex-plode.
x Never attach the negative cable from the vehicle providing starting assistance to any part of the brake hoses or brake lines.
x Never allow the non-insulated parts of the battery clamps to touch.
x Never allow the jumper cable attached to the positive battery terminal to contact metal parts of the vehicle.
x Always follow the instructions of the jumper cable manufacturer.
NOTICE
To help prevent extensive damage to the vehicle electrical system, read and heed the follow-ing:
x Connecting jumper cables improperly can cause a short circuit and do expensive damage to the vehicle's electrical system.
x Do not let the vehicles touch each other while the jumper cables are connected. If they do, electrical current may flow between the vehicles when the positive (+) terminals are connected, causing electrical system damage.

The procedure for attaching and for removing the jumper cables is described below. Perform each of the following steps only in the order described, which follow the letters shown in the illustration
⇒ fig. 183 A – B – C – D.
Attaching jumper cables
1. Switch off the ignition in both vehicles ⇒ page 205, Starting and stopping the electric drive.
2. Open the battery cover in the electric motor compartment if the battery has a cover ⇒  12 Volt vehicle battery.
3. Attach one end of the red jumper cable to the positive terminal (+) of the dead battery: (1) ⇒ .
4. Attach the other end of the red jumper cable to the positive terminal (+) of the good battery (booster battery): (2).
5. Attach one end of the black jumper cable to the negative jump-start terminal ⇒  Jump-start termi-nal, or if that is not available, to the negative terminal (-) of the battery in the vehicle providing
assistance (2) ⇒ fig. 183.
6. Attach the other end of the black jumper cable (3) to the negative jump-start terminal ⇒  Jump-start terminal, or if that is not available, a bare metal part of the vehicle with the dead battery. This part should be connected directly to the electric motor block. You may also attach the cable to the
electric motor block itself or to the towing eye installed on the front of the vehicle ⇒ page 408, Tow-
ing. Attach the clamp to a point that is as far away as possible from the dead battery (1) ⇒ .
7. Route the jumper cables so that they cannot get caught in any moving parts in the electric motor compartment of either vehicle.
Starting the electric motor
x Start the engine of the vehicle with the good battery that is providing help and let it run at idle speed.
x Turn on the ignition of your vehicle with the dead battery. If the electric motor can be activated, wait
2 to 3 minutes before removing the jumper cables as described below ⇒ . If the electric motor cannot be activated within about 10 seconds, turn off the ignition and wait at least 1 minute; then try again.
Before removing the jumper cables
x Switch off the headlights (if they are on).
x In the vehicle with the dead battery, switch on the heater fan and the rear window defroster. This helps to minimize voltage spikes when the cables are disconnected.
Removing jumper cables
With the electric motor activated, remove the jumper cables in reverse order to the way they were connected.
1. Disconnect the black (-) cable from the vehicle with the dead battery.
2. Disconnect the black (-) cable from the other vehicle (vehicle with the good battery).
3. Disconnect the red (+) cable from the other vehicle (vehicle with the good battery).
4. Disconnect the red (+) cable from the vehicle with the dead battery.
5. Close the battery cover.
6. If necessary, unscrew the towing eye on the front of the vehicle ⇒  Installing the front towing eye.
