fuel system VOLKSWAGEN TOUAREG 2017 Owner´s Manual

On hills
Before stopping the engine, turn the steering wheel so that, if the vehicle starts to roll, its front wheels will roll into the curb:
x Facing downhill, turn the front wheels so that they point toward the curb.
x Facing uphill, turn the front wheels so that they point away from the curb.
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 the hot exhaust system could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
NOTICE
x Always be careful when you park in areas with parking barriers or high curbs. These vary in height and could damage your bumper and related parts if the front of your vehicle hits a barri-er or curb that is too high while you are getting into or out of a parking spot. To help prevent damage, stop before the tires of your vehicle touch a parking barrier or curb.
x Always be careful when you enter a driveway or drive up or down steep ramps or over curbs or other obstacles. Parts of the vehicle close to the ground may be damaged (such as bumper covers, spoilers, and parts of the engine, suspension, and exhaust systems).
About the brakes

Defensive driving and “flowing” with traffic
Frequent braking and acceleration increases fuel consumption significantly. Just by driving defensively and keeping a sufficiently large distance away from the vehicle in front of you can make up for the speed fluctuations caused by taking your foot off the accelerator. Active braking and accelerating is then not necessarily required.
Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical than constantly accelerating and braking. Usually you can reach your destination just as quickly by driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the climate control system has to produce starkly con-trasting temperatures, it requires a large amount of energy, which is generated by the engine. The temperature in the vehicle should therefore not be extremely different from that of the outside tempera-ture. It may be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the windshield and rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
x Towing a trailer.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not running. The transmission will not be lubricated and will be damaged.
See additional tips on using your hybrid drive to help reduce fuel consumption.

Adjust the tire pressure
The proper tire pressure helps reduce rolling resistance as well as fuel consumption.
When purchasing new tires, always make sure that the tires are optimized for lower rolling resistance.
Use low viscosity engine oil
Fully “synthetic,” low viscosity engine oils that expressly comply with Volkswagen oil quality standards reduce fuel consumption. Low viscosity engine oils reduce the frictional resistance on the engine and are distributed more evenly and quickly, particularly when cold-starting the engine. The effect is partic-ularly apparent in vehicles that frequently travel short distances.
Always ensure the right engine oil level is maintained and keep to the scheduled service intervals (engine oil changes).
Make sure the engine oil that you purchase expressly complies with Volkswagen oil quality standards and is the oil approved by Volkswagen for your vehicle.
Avoid unnecessary weight
The lighter the vehicle, the more economical and eco-friendly it will be. For example, an extra 220 lbs (100 kg) of weight increases fuel consumption by up to 1 pint per 60 miles (0.3 l/100 km).
Remove all unnecessary items and unnecessary dead weight from the vehicle.
Remove unnecessary aftermarket components
The more aerodynamic the vehicle, the less fuel it will consume. Aftermarket components such as bicycle racks reduce its aerodynamic performance.
Therefore, remove unnecessary structures and unused rack systems, particularly if planning to drive at higher speeds.
See additional tips on using your hybrid drive to help reduce fuel consumption.

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.
Warning and indicator lights

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.

WARNING
x Even if empty, portable fuel containers can leak and cause a fire and serious personal injuries, especially in a crash.
x If, under exceptional circumstances, you must transport a portable fuel container, please observe the following:
For your safety, we strongly recommend that you do not travel with a portable fuel container in your vehicle.
– Never fill a portable fuel container while it is anywhere in or on the vehicle (for exam-ple, in the luggage compartment or on the rear hatch). Static electricity can build up while filling and can ignite fuel vapors, causing a fire.
– Always place a portable fuel container on the ground before filling. Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable.
– Always keep the filler nozzle completely inside the portable container before and dur-ing filling.
– If filling a portable container made of metal, the filler nozzle must always be in contact with the container. This will help prevent static electricity from discharging and causing a fire.
– Always observe local and state or provincial laws about the use, storage, and transpor-tation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as AN-SI/ASTM F852-86.
NOTICE
x Remove fuel spills from the vehicle immediately to help prevent damage to the paint, tires, and wheel housings.
x Refueling with gasoline when your vehicle has a diesel engine or refueling with diesel fuel when your vehicle has a gasoline engine can cause very serious and expensive engine and fuel system damage that is not covered by any Volkswagen Limited Warranty.
x If you put any amount of incorrect fuel in the fuel tank, do not start the engine under any circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance. These fuels contain substances that can severely damage the fuel system and the engine if the engine is started.
x Vehicles with diesel engines must never be refueled or driven with gasoline, kerosene, heating oil, or other non-specified fuels that have not been expressly approved for use with the diesel engine. Other kinds of fuel will cause serious damage to the fuel system and the engine that is not covered by any Volkswagen Limited Warranty.
Fuels can pollute the environment. Spilled fuel must be collected and disposed of properly, following all applicable environmental regulations.
There is no emergency release for the fuel filler flap. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility for assistance if necessary.

x Methanol-blended fuels that do not meet the criteria listed above may cause corrosion and may damage plastic and rubber parts in the fuel system.
x Never use fuels that contain lead or other metals (check listing on the fuel pump). Even lead replacement gasoline (LRP fuels) contain metallic additives in high concentrations. They can damage the engine.
x Do not use fuels that fail to meet the criteria above, or with contents that cannot be identi-fied.
x If you cannot tell whether a particular fuel blend meets the criteria above, ask your service station or its fuel supplier. If you notice a loss of fuel economy or drivability and performance problems using one of these fuel blends, we recommend that you switch to unblended fuel.
x Using fuels that are different from those specified above can damage your vehicle's engine and fuel system and cause performance problems.
x Damage to the engine and fuel system and performance problems caused by using fuels that are different from those specified above or buy using “starting assist fluids” are not the responsibility of Volkswagen and are not covered under the Emission warranties or any other Volkswagen Limited Warranty.
Even a single tank full of leaded fuel can do major damage to the catalytic converter and degrade its effectiveness in reducing polluting emissions.
If you notice a loss of fuel economy or drivability and performance problems using one of these fuel blends, we recommend that you switch to unblended fuel. Never use fuel line antifreeze offered for gasoline engines.
Gasoline additives

Using diesel fuel with concentrations of methyl ester biodiesel higher than 20 % (B20), such as B100 is still contrary to the terms of your Emission warranties or any other Volkswagen Limited Warranty and remains strictly prohibited.
Biodiesel blends (up to B20) may be used in your Illinois registered TDI® Clean Diesel vehicle; howev-er, please be aware that biodiesel has characteristics that are different from other kinds of fuel, espe-cially petroleum-based fuels.
Biodiesel can attract water and also deteriorate with age. Small amounts of biodiesel can get into the engine oil, but unlike petroleum diesel, it does not evaporate over time. This can cause the oil level in the engine to rise and can affect the quality of the oil.
x Routinely check the engine oil level. A good time to do this is when you refuel, especially if you regularly do a lot of short distance or stop-and-go driving. This will help you see if the engine oil level is getting higher. (A rising oil level beyond the maximum indicator means an oil change is needed due
to the dilution of the oil in the system; a potential characteristic of biodiesel use) ⇒ page 590, Checking the engine oil level and adding oil.
x If you ever notice that the engine oil level has risen or is above the maximum indicator, contact your authorized Volkswagen dealer, authorized Volkswagen Service Facility or Volkswagen Customer CARE to schedule an oil change – regardless of the time or mileage that has elapsed since you last had an oil change performed.
x Continue to follow the oil change intervals found in the Warranty and Maintenance booklet that came with your vehicle, and use only engine oil that expressly complies with Volkswagen quality standard VW 507 00.
x Refuel only at trusted, commercial fueling stations that are located near main highways. These stations are more likely to have “fresh” biodiesel fuels that have not aged significantly.
x If your vehicle will be in storage (or not driven) for several weeks or months, please completely fill the fuel tank. If possible, fill the tank with Ultra Low Sulfur Diesel fuel [ASTM D-975 standard Grade No. 2-D (S15)].

WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.
NOTICE
x The vehicle's diesel engine was designed solely for use with ULSD fuel. For this reason, never use gasoline, heating oil, or other fuels that have not been expressly approved for use with the diesel engine. These fuels contain substances that will severely damage the fuel sys-tem and the engine. Such damage will not be covered by any Volkswagen Limited Warranty.
x If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic part. Wash the contaminated vehicle parts right away with soap and warm water to help pre-vent leaks and serious damage.

x Damage to the engine and fuel system and performance problems caused by using fuels that are different from those specified above or by using “starting assist fluids” are not the responsibility of Volkswagen and are not covered under the Emission warranties or any other Volkswagen Limited Warranty.
x The vehicle is warranted to run on diesel fuel containing methyl ester biodiesel in concen-trations of 5 % or less. Never use methyl ester biodiesel in blend levels higher than 5 % (5 % methyl ester blends are sometimes designated or labeled as B5) unless your vehicle is regis-tered in Illinois. The properties of methyl ester biodiesel blends in levels greater than 5% will void coverage for related engine damage under the Emission warranties or any other Volkswagen Limited Warranty, unless your vehicle is registered in Illinois.
x Biodiesel especially in concentrations higher than B5, can attract water and also deteriorate with age. Small amounts of biodiesel can get into the engine oil, but unlike petroleum diesel, it does not evaporate over time. This can cause the oil level in the engine to rise and can affect the quality of the oil and if not detected and remedied promptly, will ultimately result in engine damage.
