Washing the vehicle

If you plan to take your vehicle outside the continental limits of the United States or Canada, there is the possibility that:
x Unleaded fuels for vehicles with catalytic converters may not be available.
x Ultra Low Sulfur Diesel (ULSD) fuel No. 2 that your diesel engine requires may not be available.
x Fuel may have a considerably lower octane rating and may cause engine damage.
x Service may be inadequate due to lack of proper service facilities, tools or testing equipment.
x Replacement parts may not be readily available.
x DVD navigation systems for vehicles built for the United States and Canada will not necessarily work in Europe, and may not work in other countries outside of North America.
NOTICE
Volkswagen is not responsible for mechanical damage that may result from substandard fuel or service or the unavailability of Genuine Volkswagen parts.

WARNING
Obey all applicable legal requirements when cleaning the diesel particulate filter.
x Clean the diesel particulate filter as recommended only when visibility, weather, road, and traffic conditions permit.
x Do not put others at risk.
Under certain engine conditions, you may smell a sulfur odor. This is not an indication of a mal-functioning emission control system. This depends upon the sulfur content of the diesel fuel.

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.

The release lever glows in the dark to help it be seen in low-light conditions.

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 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 engine 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 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.

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 wear proper eye protection. Never lean over the vehicle battery.
x Attach the jumper cables in the correct order: first the positive cable, then the negative cable.
x Never connect the negative cable from the vehicle providing starting assistance to parts 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 Check the battery acid level indicator window on the vehicle battery. Use a flashlight, never a match, cigarette lighter, or other open flame. If you cannot see the color of the win-dow clearly, or if it is light yellow or colorless, do not jump-start the vehicle. Get expert assis-tance.
x Avoid electrostatic discharge in the vicinity of the vehicle battery. Sparks may cause the hydrogen gas escaping from the vehicle battery to ignite.
x Never jump-start a vehicle with a battery that is damaged or frozen or that was frozen and has thawed. The battery can explode. Replace the battery instead.
x Always follow the instructions of the jumper cable manufacturer.
x Always make sure that the battery providing starting assistance has the same voltage as the dead battery (12 V) and about the same capacity (see battery label).
x Batteries give off explosive hydrogen gas. Always keep fire, sparks, open flame and smok-ing materials away from batteries.
x Never connect the negative cable from the other vehicle directly to the negative terminal of the dead battery. The hydrogen gas from the battery is explosive.
x Never short out the battery terminals by connecting the positive (+) and negative (-) termi-nals with each other.

WARNING
Towing a vehicle changes the way it handles and brakes. To help reduce the risk of an acci-dent 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.
