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 air conditioner has to produce starkly contrasting 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 temperature. 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 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.

Switching off Turn the fan switch to position 0.
WARNING
Stale air causes driver fatigue and reduces alertness, which can cause accidents, collisions, and serious personal injury.
x Never switch off the fan for a long time because no fresh air will enter the passenger compartment.
Heating and ventilation system controls

Fig. 131 In the center console: Heating system controls.

The air conditioner works only when the ignition is switched on. The cooling system for the passenger compartment works only when the engine is running and the fan is on.
The air conditioner is most efficient when the windows and the power sunroof are closed. If the vehicle is stationary and the passenger compartment becomes very hot due to sunlight, briefly opening the windows and the power sunroof may speed up the cooling process.
Keep the air intake slots in front of the windshield free of ice, snow, and leaves so that the heating and ventilation systems can work properly.
Settings for optimum visibility
When you switch on the cooling system, both the temperature and humidity in the vehicle are reduced. This will help make passengers feel more comfortable and help keep the windows from fogging up.
x Switch off the air recirculation, Air recirculation.
x Set the fan to the desired speed.
x Turn the temperature knob to the center position.
x Open and adjust all air vents in the instrument panel, Air vents.
x Turn the air distribution knob to the desired setting.
x Push the !

Switching off: Press the button 3 until the indicator light in the button goes out.
Switching air recirculation on and off: Heating and ventilation system
Switching on: Press the button  until the indicator light in the button comes on.
Switching off: Press the buttonuntil the indicator light in the button goes out.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents, collisions and serious personal injury.
x Never use air recirculation mode over an extended period of time, since no fresh air will enter the passenger compartment.
x When the air conditioner is off and recirculation mode is on, condensation can quickly form on the windows and greatly reduce visibility.
x Always switch off recirculation mode when it is not needed.
NOTICE
Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation system can leave residue on the evaporator and on the dust and pollen active carbon filter, resulting in permanent odors whenever the air conditioner is switched on.

WARNING
Even if empty, portable fuel containers can leak and cause a fire and serious personal injuries, especially in a crash.
x For your safety, we strongly recommend that you do not travel with a portable fuel container in your vehicle.
x If, under exceptional circumstances, you must transport a portable fuel container, please observe the following:
– Never fill a portable fuel container while it is anywhere in or on the vehicle (for example, in the luggage compartment or on top of the luggage compartment lid). 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 during 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 transportation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as ANSI/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.

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; however, please be aware that biodiesel has characteristics that are different from other kinds of fuel, especially 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) .255, Engine 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)].

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 prevent 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

Removing snow
Remove snow from all windows and outside mirrors with an appropriate brush.
Removing ice
The best way to remove ice is with a deicer spray. When using an ice scraper always scrape in one direction, never back and forth. Dirt can scratch the glass when moving the scraper backward.
WARNING
Dirty or fogged up windows reduce visibility and increase the risk of accidents and severe injuries.
x Don't drive until you have clear visibility through all windows.
x Remove ice, snow and condensation from all inside and outside window surfaces.
NOTICE
x Never mix recommended cleaning agents with other cleaning agents in the windshield washer reservoir. If you do, this could cause sediments or other by-products that can clog the windshield wiper nozzles.
x Never use warm or hot water to remove snow and ice from windows and mirrors. This could cause the glass to crack!
x The heating elements for the rear defroster are on the inside of the rear window. Do not put stickers over the heating elements on the inside of the rear window and never clean the inside of the windows with corrosive or acidic cleaning agents or other chemicals that could damage the heating elements.
x Antennas installed on the insides of windows can be damaged by abrasive objects or by corrosive or acidic cleaning agents or other chemicals. Do not place any stickers on the windshield-integrated antenna and never clean the antenna with corrosive or acidic cleaning agents or other chemicals.

Ease off the accelerator. Carefully drive to the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility. Have engine checked.

The catalytic converter provides exhaust gas after-treatment to help reduce pollutants in the exhaust gas. To help ensure long service life of the exhaust system and gasoline engine catalytic converter:
x Only use unleaded fuel.
x Never completely empty the fuel tank.
x Do not exceed the correct oil level, Engine oil.
x Do not tow the vehicle to start it, but use a jump-start instead, Jump-starting.
If you experience misfires, loss of power or the engine is not running smoothly while driving, reduce speed immediately and have the vehicle checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Otherwise, gasoline could reach the exhaust system and get into the atmosphere. The catalytic converter could also be damaged by overheating!
Under certain engine conditions, you may smell a sulfur odor. This is not an indication of a malfunctioning emission control system. This depends upon the sulfur content of the diesel fuel.
