WARNING
Improper replacement of burned out headlights and other light bulbs can cause serious personal injury.
x Stop! Always read and heed the WARNINGS before doing any work in the engine compartment, Working in the engine compartment. The engine compartment of any motor vehicle is a potentially dangerous area, and work in this area can lead to serious personal injury.
x HID – High Intensity Discharge (Xenon) headlights get power from a high voltage source that can cause severe personal injury and even death if handled improperly.
x H7 bulbs and HID – High Intensity Discharge (Xenon) headlights are under high pressure and can explode if handled improperly.
x Always let a burned out light bulb cool down before replacing it.
x Never replace a light bulb unless you are familiar with all of the necessary procedures. In particular, never remove a headlight unless you know exactly how to carry out the job and have the correct tools and light bulbs.
x If you are uncertain about what to do, have the work performed by an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon) headlights and H7 bulbs replaced by a qualified technician.
x Do not touch the glass of light bulbs with your bare hands. Fingerprints left on the bulb evaporate due to the heat when the bulb is switched on and cause the reflector to “cloud.”
x There are sharp edges on and around the headlight housing in the engine compartment and the rear light housing. Wear hand protection if you replace bulbs.
NOTICE
After replacing a headlight bulb or other light bulb, always make sure that the rubber covers or plastic caps have been properly and securely reinstalled to help prevent water from getting into the electrical connections and headlight housing and damaging the electrical system.

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, Vehicle battery.
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 battery label).
x Never jump-start a vehicle with a thawed or frozen vehicle 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 explosive! Always keep fire, sparks, open flame, and smoking materials far away from vehicle batteries. 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 hydrogen 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 (+) 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 explode.
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 following:
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.

Attaching jumper cables
1. Switch off the ignition in both vehicles, Starting and stopping the engine.
2. Open the battery cover in the engine compartment if the battery has a cover, 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 terminal (-) of the booster battery: (2) .
6. Attach the other end of the black jumper cable (3) to a bare metal part of the vehicle with the dead battery. This part should be connected directly to the engine block. You may also attach the cable to the engine block itself or to the towing eye installed on the front of the vehicle, Towing.
Attach the clamp to a point that is as far away as possible from the dead battery (1) ⇒ . On
vehicles with vehicles with a 1.8 liter engine, see ⇒ fig. 179.
7. Route the jumper cables so that they cannot get caught in any moving parts in the engine compartment of either vehicle.
Starting the engine
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 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
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 engine running, 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.

WARNING
Towing a vehicle changes the way it handles and brakes. To help reduce the risk of an accident and serious personal injury, note the following:
x The driver of the vehicle that is being towed:
– Since the brake booster also does not work when the engine is stopped, you will need to press harder on the brake pedal to slow down or stop. Always be alert so as not to rear-end the towing vehicle.
– Will have to use considerably more force to turn the steering wheel because the power steering is not working.
x The driver of the vehicle that is doing the towing:
– Must accelerate gradually and gently and avoid jerking movements.
– Must not brake hard or steer sharply.
– Must brake earlier and more gently than in normal driving.
NOTICE
x Be careful not to damage the paint when installing and removing the towing eye and the cover for the threaded hole behind the bumper.
x Unburned fuel can get into the catalytic converter during towing and damage it.

When not to tow your vehicle
In the following situations, the vehicle cannot be towed and must be transported on a flatbed truck or trailer:
x If transmission fluid has leaked out of the transmission.
x If there is little or no oil in the transmission because of damage to your vehicle, it must be moved with the drive wheels off the ground.
x If the front and rear wheels cannot turn.
x When the vehicle battery is dead, because the steering may remain disabled and it may not be possible to release the electronic steering column lock.
x If you have to tow an automatic transmission vehicle more than 30 miles (50 km).
Towing other vehicles
x Obey all legal requirements
x Read and heed all towing information in the owner's manual for the other vehicle.
A vehicle can be towed only if the electronic steering column lock is released. In case of a power loss or malfunctions of the electrical system, the engine may have to be jump-started in order to release the electronic steering column lock.
