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

x If you must fuel your vehicle with gasoline whose octane rating is too low, only drive with the engine speed in the middle of the rpm range and with low engine load. Avoid high rpm and heavy engine load. Otherwise, the engine could be damaged. Refuel your vehicle with gasoline with the required octane rating as soon as possible.
x Do not use fuel that is labeled at the pump as containing metal. Lead replacement fuel contains high concentrations of metallic additives. Engine damage could result.
x Fueling your vehicle just one time with leaded fuel or fuel that contains other metallic addi-tives can affect the performance of the catalytic converter and cause extensive damage to it.
Diesel fuel

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.

x Press the refill container down into the tank filler neck and hold it there.
x Add at least 1.5 gallons (5.7 liters) of AdBlue which is 3 refill bottles. Adding a smaller amount is not sufficient.
x Wait until the contents of the refill container has flowed into the AdBlue tank. Do not squeeze or damage the refill container!
x Unscrew the refill container counterclockwise and lift it out carefully ⇒ .
x AdBlue stops flowing from the refill bottle when the AdBlue tank is completely full.
Closing the fuel filler neck
x Screw in the fuel filler neck cap (5) clockwise until the cap locks into place.
x Put the plug ⇒ fig. 308 (4) back in the spare wheel recess and make certain it is properly placed and secure.
x Put the collapsible spare tire (2) back in the spare wheel recess and secure it with the fastening screw (3) and washer.
x Unhook the luggage compartment floor panel (1) and fold down or, if you have a reversible lug-
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.

NOTICE
x Use only AdBlue® or any Diesel Exhaust Fluid that expressly conforms to International Organization for Standardization specification ISO 22241-1. Using a DEF that does not meet the requirements of ISO 22241-1 can seriously damage your vehicle’s engine.
x Never mix water or any other substances or additives with AdBlue. Damage caused by such additives will not be covered by any Volkswagen Limited Warranty.
x Never put AdBlue into the diesel fuel tank! Otherwise the engine may be damaged!
x Do not carry a refill container in the vehicle all the time or routinely. Due to temperature fluctuations and damage, the container could start leaking and the AdBlue could damage the vehicle interior.
Dispose of the refill container in an environmentally-responsible manner.
Appropriate AdBlue refill containers can be obtained from an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

WARNING
Inadequate experience and knowledge of the demands of off-road driving can lead to critical situations and cause serious personal injury.
x Never take routes or risks that could put you or your passengers in danger. If you cannot go on, or have doubts about the safety of your route, turn back and take a new route.
x The intelligent technology of the vehicle cannot change the laws of physics. Despite the ABS, adverse terrain can cause instability through blocked wheels – for example, if you brake hard when driving on a loose gravel road. Difficult terrain may also prevent the ESC from doing its job.
x Never operate the vehicle at the limit of its performance ability. Always leave a good safety margin.
x To reduce the risk of loss of control and serious personal injury, never use the cruise control when driving off-road.
x Even terrain that looks easy can be difficult and dangerous, putting you and your passen-gers in a critical situation. It is often best to check an area out on foot first.
x Drive with special care and think ahead in off-road terrain. If you drive too fast, or fail to maneuver the vehicle properly, you could cause personal injury and damage the vehicle.
x Never drive faster than is appropriate for the prevailing terrain and the road, traffic, and weather conditions.
x Never drive too fast across embankments, ramps, or slopes. The vehicle could become airborne. If that happens, you will not be able to steer and can lose control.
x If your vehicle becomes airborne, always keep the front wheels pointing straight ahead. If the wheels are not pointing straight ahead when the vehicle lands, it could roll over.
x Never allow people to stand in front of or behind the vehicle if you have put items such as stones or pieces of wood under the wheels to improve traction on slippery ground. Spinning wheels can turn these items into dangerous flying objects causing serious personal injury.
x Even areas that look harmless can be dangerous. Potholes, ditches, trenches, drop-offs, different kinds of obstacles, and soft or swampy ground often cannot be seen and can be partially or fully covered by water, grass, branches, or other things. Driving over such terrain can cause accidents and severe injuries. Before crossing an unknown area, carefully explore the route you plan to take on foot.
WARNING
Never drive off-road if you are low on fuel. Too little fuel in the tank can cause an accident and serious injuries. You can also run out of fuel in a remote area where getting help is diffi-cult or impossible.
x When the fuel tank is almost empty, fuel supply to the engine can be interrupted, especial-ly when driving over bumps, across slopes, and up and down hills. The interruption in fuel flow could stall the engine during a maneuver in difficult terrain and make you lose control of the vehicle.
x Steering and braking assistance as well as ESC and related systems will not work if the engine “sputters” or stalls due to lack of fuel. This can cause loss of vehicle control, espe-cially in difficult terrain.
x Always refuel when the tank is 1/4 full to reduce the risk of running out of fuel.
NOTICE
If the power sunroof or the windows are open when it rains or snows, the interior of the vehicle will get wet and the vehicle may be damaged. Always keep the windows and the power sunroof closed when driving off-road.

x Always dry the brakes by braking a couple of times.
x After driving through water, have the vehicle drive train and electrical system thoroughly inspected for damage by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
WARNING
Flowing water is very powerful and can sweep your vehicle away. This can lead create an extremely dangerous situation and cause an accident with serious personal injuries.
x Never take routes or risks that could put you or your passengers in danger. If you cannot go on or have doubts about the safety of your route, turn back and take a new route.
x Never stop in the water.
x If water gets into the engine, your vehicle can break down. You will lose control of a bro-ken down vehicle, and it can be swept away.
x Soft surfaces, mud, underwater obstacles, and holes can cause accidents and can cause the vehicle to break down in the water. This can lead pose extreme danger.
x Rapidly flowing water can develop strong forces that can pull the vehicle downstream. This can cause accidents and fatal injuries.
x Drive through water only where the banks and bottom are firm enough and the water is
shallower at all points than the maximum permissible fording depth for your vehicle ⇒ table on page 556.
NOTICE
x Vehicle components such as the engine, drive train, suspension or electrical system may be severely damaged by driving through water.
x Avoid stopping in deep water. This can let water get inside the vehicle.
x On soft ground, the tires dig into the surface. This reduces fording depth. Make sure that the ground is sufficiently firm.
x Avoid creating a bow wave in front of the vehicle while driving through water. A bow wave could force its way into the engine air intake duct and seriously damage the engine.
x If you even briefly exceed the maximum fording depth when driving through water, severe engine damage will result. This engine damage will lead to a vehicle breakdown. This can disable the vehicle in the water.
x Never drive over salt flats or through salt or salty water. Salt causes vehicle corrosion. Rinse all parts of the vehicle that were exposed to salt or salt water right away with fresh water.
Driving over snow-covered terrain

WARNING
Never try to drive up or down slopes that are too steep for your vehicle. The vehicle could slide away, tip over, or roll over.
x Never take routes or risks that could put you or your passengers in danger. If you cannot go on or have doubts about the safety of your route, turn back and take a new route.
x The lateral angle must never be more than the maximum angle approved for the vehicle.
x Always drive along the fall line when driving up or down a slope.
x Never try to turn the vehicle around on a slope. The vehicle could tip over or roll down the slope.
x If the engine stalls or you can no longer drive up the slope for any reason, stop and apply the foot brake. If stalled, apply the foot brake and restart the engine. Then shift into Reverse (R) and carefully back your vehicle straight down the slope along the fall line. Keep the vehi-cle speed slow and even.
x If the engine will not restart, apply constant pressure to the foot brake and carefully back straight down the slope the same way you drove up. Keep the vehicle speed slow and even.
x If the engine is running, select Reverse and carefully back straight down the slope the same way you drove up. Use engine braking power and the foot brake to keep the vehicle speed slow and even.
x Never just roll down a slope with the transmission in Neutral (N). You could lose control of the vehicle.
