NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x If the 12 Volt battery is disconnected or dead or has been replaced, there is a possibility that the combustion engine will not automatically switch off when the vehicle is powered by the electric motor. If this situation persists for several days, take the vehicle to an authorized Volkswagen dealer or an authorized Volkswagen Service Facility that is qualified to do work on hybrid vehicles.
x Never transport water or other liquids or fluids in open containers, such as an aquarium. If liquid is spilled in the luggage compartment, this can cause short circuits or damage the high-voltage battery.
NOTICE
Never block or cover the cooling air vents for the high-voltage hybrid battery under the rear seat. Blocking or covering these vents can damage the high-voltage battery.
NOTICE
If the vehicle is not used for a longer period, the high-voltage battery will run down. To keep the high-voltage battery in good condition, the vehicle needs to be driven at least every 2 months for at least 30 minutes or 15 miles (20 km).
x If the high-voltage battery is dead, the gasoline engine will not start. Contact an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop for assistance.

Zero Emission Displays the emission-free driving time as a bar graph. Each bar represents 1 minute of driving. The height of the bar indicates the proportion of emission-free driving in %.
A full bar, or 100% ⇒ fig. 129 (1), is a 1 minute interval of emission-free hybrid driving or sailing. No bar, or 0% (2), is a 1 minute interval driving only with the combustion engine. The display shows the emissions for a maximum of 30 minutes. Tapping Reset resets all values on this graph to zero.

DANGER
The vehicle's high-voltage electrical system and high-voltage battery are dangerous and can cause burns, other serious personal injuries, electrocution, and death.
x Always assume that high-voltage battery and parts of the high-voltage system are fully charged and energized.
x Never touch or let jewelry or other metal objects contact high-voltage cables or the high-voltage battery and battery poles, especially if the cables, battery, and battery poles have been damaged in any way.
x Never do any work yourself on the high-voltage electrical system, the orange-colored high-voltage wiring, or on the high-voltage battery.
x Never open, service, repair, or disconnect any part of the hybrid electrical system.
x Never damage the orange-colored high-voltage cables. Never remove them and never disconnect them from the high-voltage electrical system.
x Never open or remove the orange-colored cover on the high-voltage battery.
x Always have work on the hybrid electrical system and systems that could be indirectly affected by it done by qualified, trained technicians who have the know-how, experience, documentation, and tools to do the work safely.
x All work on the high-voltage electrical system and the high-voltage battery must be done in compliance with Volkswagen standards and guidelines.
x Vehicle keys must be safely stored a safe distance from vehicle so that the ignition cannot be switched on and energize the electrical system.
x Gases vented or released from the high-voltage battery vapors are potentially poisonous and can burn.
x Physical damage to the vehicle or the high-voltage battery can result in immediate or delayed release of poisonous gases that can also cause a fire.
x Always avoid contact with leaking fluids and gases escaping from the battery, particularly one that has been damaged.
x Always tell emergency responders that the vehicle has a high-voltage battery.
WARNING
Unintended vehicle movement during maintenance work can cause serious personal injuries.
x Never work under the vehicle unless you have safely secured the vehicle from moving. If you must work under the vehicle with the wheels on the ground, always make sure that the vehicle is on level ground, that all 4 wheels are chocked to keep them from moving, and that the key is not in the ignition.
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle is safely supported on safety stands intended for that purpose that are strong enough to support the weight of the vehicle. The jack supplied with the vehicle is not strong enough for this purpose and can collapse causing serious personal injury.

WARNING
The engine compartment of any motor vehicle is a potentially dangerous area and can cause serious personal injury.
x Always use extreme caution when doing any work in the engine compartment. Always follow commonly accepted safety practices and use common sense. Never risk personal injury.
x Never perform any work in the engine compartment unless you know exactly how to carry out the job and have the correct technical information and the correct tools.
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. Serious personal injury may result from improperly performed work.
x Never open or close the engine hood if steam or coolant is escaping. Hot steam or coolant can cause serious burns. Always wait until you no longer see or hear steam or coolant escaping from the engine.
x Always let the engine cool down completely before carefully opening the hood.
x Hot parts of the engine and the exhaust system will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the remote control vehicle key is out of range of the vehicle and that the vehicle cannot be started by depressing the starter button, Starter button.
– Always keep children and others away from the engine compartment and never leave them unsupervised.
x The engine coolant system is under pressure when the engine is hot. Never unscrew the coolant expansion tank cap when the engine is hot. Hot coolant can spray out and cause severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclockwise direction while applying light downward pressure on the top of the cap.
– Always protect your face, hands, and arms from hot escaping coolant or steam by covering the cap with a large, thick rag.
x Never spill fluids on the engine or exhaust system when refilling. Spilling fluids onto hot parts of the engine or exhaust system can cause a fire.
