Working on the batteries or the electrical system in your vehicle can cause serious acid burns, fires, explosions, or electrical shocks. Always read and heed the following WARNINGS and safety precautions before working on the batteries or the electrical system.
x Before working on the electrical system, always switch off the ignition and all electrical consumers and disconnect the negative cable (–) from the standard 12 Volt vehicle battery.
x When you change a light bulb, always switch off the light first.
x Always keep children away from battery acid and vehicle batteries in general.
x Always wear eye protection. Never let battery acid or lead particles come into contact with your eyes, skin, or clothing.
x Sulfuric battery acid is very corrosive. It can burn unprotected skin and cause blindness. Always wear protective gloves and eye protection. To reduce your risk of injury, never tilt the batteries, as this could spill acid through the vents and burn you.
x If you get battery acid in your eyes or on your skin, immediately rinse with cold water for several minutes and then get immediate medical attention. If you swallow any battery acid, get medical attention immediately.
x When disconnecting the batteries from the vehicle electrical system, always disconnect the negative cable (–) first and then the positive cable (+).
x Always switch off all electrical consumers before reconnecting 12 Volt vehicle batteries. Reconnect the plus cable (+) first and then the negative cable (–). Never reverse the polarity of the connections. This could cause a fire.
x A highly explosive mixture of gases is given off when the battery is being charged.
x Do not smoke and avoid fires, sparks, and open flames when working. Never create sparks or electrostatic charges when handling cables and electrical equipment. Never short circuit the battery terminals. High-energy sparks can cause serious personal injury.
x Never use or attempt to charge a damaged or frozen battery, or a battery that was frozen but has thawed. Charging a frozen or thawed battery could cause explosions and chemical burns! Replace damaged or frozen vehicle batteries immediately. A dead battery can freeze at temperatures around +32 °F (0 °C).
x If the battery has a vent line or tube, make sure that this it is properly connected to the battery.
x Always make sure that the vent line is securely attached to a vehicle battery that is located in the luggage compartment.
WARNING
California Proposition 65 Warning
x Battery posts, terminals, and related accessories contain lead and lead components, chemicals known to the State of California to cause cancer and reproductive harm. Wash your hands after handling.
NOTICE
x Do not expose the vehicle battery to direct sunlight for an extended period of time as ultra-violet rays may damage the battery housing.
x If the vehicle is left standing in the cold for a long time, protect the vehicle battery from freezing. A battery will be permanently damaged by freezing.

If the battery was disconnected for a long time, the next scheduled service may not be correctly calcu-lated and displayed. The maximum permissible service and maintenance intervals 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. 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 work-shop for assistance.
Automatic electrical load deactivation
If the vehicle battery drain is high, the intelligent on-board 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.
x When the engine is started, the power supply to the 12 Volt sockets and the cigarette lighter is temporarily interrupted.
The on-board electrical system management cannot always keep the battery from being drained. For example, the battery will drain if the engine is not running, but the ignition is switched on or the parking lights are left on for a long time when parked.
Battery disconnection in an accident with airbag deployment
In vehicles with a battery in the luggage compartment, the electrical connection to the battery is dis-connected automatically in a collision with airbag deployment. This helps to prevent a short-circuit.
What drains the vehicle battery?
x Long periods when the engine is not running, especially when the ignition is on.
x Using electrical systems or devices when the engine 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 (P) when the ignition is
switched off ⇒  Automatic transmission: 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). Always replace a battery that has frozen.
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 (-).

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 battery. The battery can explode. 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 cellular 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 engine compartment.
x Never short out the battery terminals by connecting the positive terminal (+) and negative (–) terminals 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 fuel system or to 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 in which it is described.
Before you begin
d Switch off the ignition in both vehicles.
d Open the hoods of both vehicles.
d Remove the cover from the positive terminal on your vehicle and, if necessary, the battery cover of the other vehicle.

Starting the engine
1. Start the engine of the vehicle with the good battery that is providing help and let it run at idle speed.

2. Turn the ignition of the vehicle with the dead battery. If the engine starts, wait 2 to 3 minutes until it
“runs smoothly” before removing the jumper cables as described below ⇒ . If the engine does not start within about 10 seconds, turn off the ignition and wait at least 1 minute; then try again.
Before removing the jumper cables
1. Switch off the headlights (if they are on).
2. In the vehicle with the dead battery, switch on the heater fan and the rear window defroster. This helps tit minimize voltage spikes when the cables are disconnected.
Removing the jumper cables
1. Before you remove the jumper cables, switch off the headlights (if they are on).
2. 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 jumper cables are disconnected.
3. With the engine running, remove the jumper cables in reverse order to the way they were con-nected. Specifically:
– Disconnect the black (–) cable from the vehicle with the dead battery.
– Disconnect the black (–) cable from the other vehicle (vehicle with the good battery).
– Disconnect the red (+) cable from the other vehicle (vehicle with the good battery).
– Disconnect the red (+) cable from the vehicle with the dead battery.
4. Turn off the heater fan and the rear winder defroster on the vehicle with the dead battery.
