2012 VOLKSWAGEN TOUAREG ECU

WARNING
Improper use of a collapsible spare tire can cause loss of vehicle control, a crash or other accident, and serious personal injury.
x Never use a collapsible spare tire if it is damaged or worn down to the wear indicators.
x The collapsible spare tire is identified by a sticker and the words “50 mph” or “80 km/h”. This is the maximum permissible speed when driving with this tire.
x Never drive faster than 50 mph (80 km/h) with a collapsible spare tire. Avoid full-throttle acceleration, heavy braking, and fast cornering!
x Never drive more than 125 miles (200 km) if a compact spare wheel is installed on the front axle (drive axle).
x Replace the collapsible spare tire with a normal wheel as soon as possible. Collapsible spare tires are designed for brief use only.
x Regularly check U.S. DOT tire identification number (TIN) to determine the age of the col-
lapsible spare tire ⇒  Tire labeling. Tires age even if they are not being used and can fail sud-denly, especially at higher speeds.
x Tires that are more than 6 years old can only be used in an emergency and then with spe-cial care and at lower speeds.
x The collapsible spare tire must always be secured with the wheel bolts provided by the factory.
x Never drive using more than one collapsible spare tire.
x After installing the collapsible spare tire, the tire pressure must be checked as soon as
possible ⇒  Tire inflation pressure.
x Snow chains cannot be used on the collapsible spare tire. If you need the snow chains, but one of the front tires is flat, you have to mount the collapsible spare tire on the rear axle. The tire taken off the rear axle can then be used to replace the flat front tire. Be sure to main-tain the tire's direction of rotation. Install the snow chains on the full-sized road wheel.
If possible, fasten the collapsible spare tire or the wheel you took off the vehicle securely in the luggage compartment. On vehicles equipped with a tire mobility set, the tire you took off the vehicle cannot be secured.

Safety information on Infotainment System
WARNING
Driving on today's roads demands the full attention of the driver at all times. Driver distrac-tion causes accidents, collisions and serious personal injury!
x Never let yourself be distracted when setting, adjusting, or using the Infotainment System, when using your mobile phone, or when operating the mobile phone controls.
x Always drive attentively and responsibly. Use the Infotainment system, your mobile phone, and the mobile phone controls only if road, traffic, and weather conditions permit and you will not be distracted from your driving.
x If you cannot use the Infotainment System, your mobile phone, or the mobile phone con-trols safely while driving, wait until later or find a safe spot where you can pull off the road and park the vehicle.
x Always set sound volume levels so that you can clearly hear horns, sirens, and other warning sounds outside the vehicle.
x Setting the sound volume too high may damage your hearing. This applies even if you are exposed to high volumes for short periods only.
WARNING
The volume level may suddenly get louder change when you switch media source or connect a new audio source.
x Always lower the base volume before switching media source or connecting a new audio source.
WARNING
Driving recommendations and traffic symbols displayed by the navigation system may differ from the current traffic situation.
x Traffic signs and traffic regulations have priority over the recommendations and displays provided by the navigation system.
x Always adjust your speed and driving style to road, traffic, weather, and visibility condi-tions.
WARNING
External devices that are loose in the vehicle or not properly secured could be thrown around the interior and cause injuries during a sudden driving or braking maneuver, or in a crash.
x Never put or attach an external device on a door, on the windshield or above or near to the areas marked “AIRBAG” on the steering wheel, the instrument panel and the seat backrests, or between these areas and the vehicle occupants.

WARNING
When powered by the electric motor, the vehicle makes much less noise, both when idling and driving, than when it is running on the internal combustion engine. It is much harder or even impossible for the drivers of other vehicles and above all for cyclists, pedestrians, and children to hear the vehicle when it is running on electrical power.
x Pedestrians and others can be struck and seriously injured because they cannot hear the vehicle and tell that it is getting close to them, for instance when you are parking, backing up, or driving in a low-speed zone where there is likely to be pedestrian traffic.
x Always watch out for pedestrians, especially small children, cyclists, and others who may not hear the vehicle or realize that it is about to move or will cross their path of travel.
x Always be especially careful in residential areas, school zones, and other places where the speed of motor vehicles is restricted and pedestrians may be at greater risk.
x Make sure the ignition and the hybrid drive system have both been turned off before leav-ing the vehicle.
WARNING
Never leave the vehicle when hybrid drive system indicator lights are still lit. The vehicle can move if the accelerator is depressed even though the combustion engine has been stopped. This can cause accidents and severe or fatal injuries.
x Make sure the transmission is in Park (P) before you get out of the vehicle.
WARNING
Never support the vehicle with cinder blocks, bricks, or other objects to inspect it. The vehi-cle could slip or move suddenly and cause an accident with serious personal injury.
WARNING
Never let the hybrid battery get wet. Liquids and other fluids can cause short circuits, electri-cal shock, burns, and explosions.
x Never carry large amounts of liquids or other fluids in the luggage compartment.
x Always make sure that any containers with liquids and other fluids are properly secured and tightly closed to prevent leakage during normal driving as well as hard cornering, brak-ing, and other vehicle maneuvers. Leaking liquids can get into the cover of the high-voltage battery and the high-voltage cable connections. This can damage the electrical system and the high-voltage battery.
Never drive until the fuel tank is completely empty. There may not always be enough charge in the high-voltage battery to get to the next gas station.
When outside temperatures are low, a cold high-voltage battery can affect how the combustion engine starts up and can also reduce the vehicle's range in electric drive.

This depends on vehicle conditions of the hybrid drive system is normal and is designed to save fuel. The power steering and the braking assistance systems remain active. In certain situations it may be necessary for the system to start the combustion engine even when the vehicle is not moving. With prolonged driving in traffic jams, the combustion engine will be switched on and off to charge the high-voltage battery for the following start-stop phase.
Sailing
If the accelerator is not depressed and the lever is in Drive (D), the internal combustion engine is switched off even at higher speeds. The vehicle then decelerates slower than conventional vehicles.
This feature can be used to help reduce fuel consumption when you keep traffic conditions in mind and can anticipate the vehicles power requirements. Even in this case, the rev counter in the instru-ment cluster displays zero engine speed (0 engine revolutions). The instrument cluster powermeter shows zero.
Brake energy regeneration (Recuperation/charge)
When the vehicle brakes, the electrical energy is generated by the electric motor, which works as an alternator and charges the high-voltage battery. The same thing occurs while the vehicle is coasting to a stop or driving downhill.
Energy regeneration is shown in the instrument cluster display or on the Infotainment System screen. The combustion engine may be switched off automatically in this situation. The instrument cluster powermeter registers below zero.
When the high voltage battery is fully charged, there is no brake energy recuperation, and therefore no engine braking. Recuperation and engine braking are also automatically reduced if the vehicle detects that the road conditions do not permit sufficient contact between the wheels and the road surface.
Automatic starting - combustion engine
The combustion engine is started automatically in a number of situations.
x Engine temperature is too low.
x Catalytic converter temperature is too low.
x High-voltage battery being charged at high rate when decelerating. The high-voltage battery can-not absorb any more energy and for this reason the electric motor cannot brake the vehicle. The combustion engine comes on to help slow the vehicle down (engine brake).
x Engine hood is open.
x Leaving the vehicle when the electric motor is still “live”. The status of the electric motor is not always obvious, particularly when the combustion engine is not running. The combustion engine will therefore start if the driver's safety belt is unlatched or the driver's door is opened when the transmis-
sion is in Park (P) or Neutral (N) ⇒  Warning when leaving the vehicle.

gage compartment floor panel, put this back in ⇒  Luggage compartment.
Things to do before driving again
x After refilling, switch on only the ignition.
x Leave the ignition switched on for at least 30 seconds so that system can detect the refill.
x Do not start the engine for 30 seconds!
WARNING
Store AdBlue only in its closed original container and in a safe place.
x To reduce the risk of poisoning, never keep AdBlue in empty food or beverage containers that might mislead someone into drinking from them.
x Always store AdBlue outside the reach of children.
