2012 VOLKSWAGEN JETTA heating

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)].

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 system 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 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.
