Oil check VOLKSWAGEN JETTA 2012 Owners Manual

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)].

Treating stains
When treating stains, it may be necessary to clean the entire surface and not just the stain itself. This is especially true if the entire surface has become dirty from normal use. Otherwise, the area that is treated may become lighter than the untreated area. If you have questions or concerns, consult a professional cleaner.

Type of stain Recommended cleaning for fabric and upholstery
Water-based stains, such as coffee or fruit juice. – Moisten a sponge with water and rub the stain gently with a circular motion. – Wipe dry with an absorbent cloth.
Persistent stains, such as chocolate or make-up. – Use only Volkswagen-approved cleaning products. – If necessary, have the fabric or upholstery professionally cleaned.
Grease-based stains, such as oil, lipstick, etc. – Use only Volkswagen-approved cleaning products. – If necessary, have the fabric or upholstery professionally cleaned.
WARNING
If there is a malfunction in the airbag system, the airbag may not deploy correctly or at all, or it may deploy unexpectedly. This could cause fatal injuries.

NOTICE
If the upholstery on power seats, heated seats, or seats with airbag components is wet, electrical components and the vehicle electrical system could be damaged.
x If the seating surface becomes soaked, have it dried and the system components checked immediately by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
x Do not use steam cleaners because the steam could cause the dirt to penetrate deeper into the fabric and make it impossible to remove.
x Power washers and cooling sprays can damage the upholstery.
NOTICE
x Clean only the carpet and floor mats with brushes. Other textile surfaces can be damaged by brushes.
x If detergent pastes or mild detergent solutions are applied with a damp cloth or sponge, the surfactants in the detergent may cause visible lines to form at the edges of the area where the detergent was applied. These lines are generally difficult or impossible to remove.

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.

Wheel bolt tightening torque
Correctly tightened bolts for steel and alloy wheel rims should have a torque of 88 ft-lbs (120 Nm). After changing a wheel, have the wheel bolt tightening torque checked right away with an accurate torque wrench.
Before you check the tightening torque, replace corroded and difficult-to-turn wheel bolts and clean the threads in the wheel hub.
Never grease or oil the wheel bolts and the threads in the wheel hubs. The bolts can come loose while driving if greased or oiled, even if tightened to the required torque.
WARNING
Improperly tightened wheel bolts can come loose while driving and cause you to lose control over the vehicle, resulting in accidents and serious injuries.
x Only use wheel bolts that belong your vehicle and to the wheel being installed.
x Never use different wheel bolts.
x Wheel bolts and wheel hub threads must always be clean, easy-to-turn and free of oil and grease.
x Only use the lug wrench that is supplied with the vehicle to loosen the wheel bolts.
x Loosen the wheel bolts only about 1 turn before lifting the vehicle with the jack.
x Never grease or oil the wheel bolts and the threads in the wheel hubs. The bolts can come loose while driving if greased or oiled, even if tightened to the required torque.
x Never loosen bolted connections on wheel rims with bolted rim rings.
x If the wheel bolts are not tightened to the proper torque, the wheel can come off the vehicle when it is moving. Extremely high torque can damage the wheel bolts and/or their threads.
Lifting the vehicle with the vehicle jack
