Tips on handling fuel  
The fuel filler flap is located on the rear passenger side of the vehicle.  
WARNING  
Improper refueling or handling of fuel is dangerous and can cause fire, explosion, and severe burns.  
Fuel is highly flammable and explosive; it can cause severe burns and other severe injuries.  
During refueling, the engine and the ignition must be switched off for safety reasons.  
Never use a mobile telephone, CB radio, or other radio equipment while refueling. The electromagnetic radiation can cause sparks that can ignite fuel  
vapors and cause a fire.  
Never get back into your vehicle while refueling. If in exceptional circumstances you must get back in your vehicle while refueling, make certain that you  
close the door and touch metal to discharge static electricity before touching the filler nozzle again. This helps avoid the buildup of static electricity, which  
can cause sparks that can ignite fuel vapors released during refueling.  
Always make sure that the fuel filler cap is screwed on all the way. This helps keep fuel from spilling out or evaporating.  
Failure to shut the engine off while refueling and/or to insert the pump nozzle all the way into the fuel filler neck can cause fuel to overflow and to spray out.  
Fuel spray and overflowing fuel are dangerous because they can cause fire and serious personal injury.  
Never smoke or have an open flame (or sparks, cigarettes, or other smoldering objects) anywhere in or near your vehicle when refueling or filling a  
portable fuel container.  
Follow all safety instructions and procedures that apply at the service station where you refuel.  
Never spill fuel in the vehicle or the luggage compartment.  
WARNING  
Even if empty, portable fuel containers can leak and cause a fire and serious personal injuries, especially in a crash.  
For your safety, we strongly recommend that you do not travel with a portable fuel container in your vehicle.  
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 trunk 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.  
NOTE  
Remove fuel spills from the vehicle immediately to help prevent damage to the paint, tires, and wheel housings.  
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.  
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.  
Fuels can pollute the environment. Spilled fuel must be collected and disposed of properly, following all applicable environmental regulations.

⇒ Gasolineꢀ  
⇒ Gasoline additivesꢀ  
The correct fuel grade for your engine is shown on a sticker located on the inside of the fuel filler flap ⇒ Fig. 191ꢀ.  
Bad or poor quality fuel reduces operating performance, efficiency and service life of the engine. If you notice any symptoms like rough engine idle or performance  
or bucking, immediately reduce the vehicle speed, accelerate slowly, and keep the engine speed in the middle of the rpm range. Avoid high rpm and rapid  
acceleration. If these symptoms should appear right after refueling, switch off the engine. In both cases contact an authorized Volkswagen dealer or an authorized  
Volkswagen Service Facility to have the engine checked.  
WARNING  
Improper refueling or handling of fuel can cause fire, explosion, and severe burns.  
Fuel is highly explosive and flammable and can cause severe burns and other injuries.  
Heed applicable safety warnings and obey local fuel handling regulations.  
Always make sure the fuel cap is screwed on all the way. This keeps fuel from spilling out and from evaporating.  
Failure to shut the engine off while refueling and/or to insert the pump nozzle fully into the vehicle's filler neck could cause fuel overflow and fuel spray.  
Fuel spray and overflowing fuel are dangerous because they can cause fire or serious injury.  
For safety reasons, the engine must be turned off when refueling.  
Never get back into your vehicle while refueling. If in exceptional circumstances you must get back in your vehicle while refueling, make certain that you  
close the door and touch metal to discharge static electricity before touching the filler nozzle again. Static electricity can cause sparks that can ignite fuel  
vapors released during refueling.  
Gasoline  
Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ  
Octane rating  
Octane rating indicates a gasoline's ability to resist engine-damaging “knock” caused by pre-ignition. Using gasoline that does not meet minimum octane  
requirements can affect engine performance, while the use of poor quality gasoline or gasoline with octane levels below 87 can also cause engine damage. If  
Regular gasoline is recommended for your engine, you may be able to enhance engine performance by using Premium gasoline.  
The recommended gasoline octane rating for your engine is listed on a label inside of the fuel filler flap. This rating may be specified according to AKI (CLC) or RON  
(ROZ) standards.  
Regardless of whether unleaded Regular or Premium grade gasoline is specified for your vehicle, Volkswagen recommends using TOP TIER Detergent Gasoline  
with a minimum octane rating of 87 AKI (91 RON) for Regular gasoline, and 91 AKI (95 RON) for Premium gasoline. For more information on TOP TIER Detergent  
Gasoline, please go to the official website, .  
The gasoline grades most commonly sold in the United States and Canada have the following octane ratings, which can usually be found on the filler pump:  
Regular grade: 87 to 90 AKI  
Premium grade: 91 to 96 AKI  
Unleaded gasoline  
Unleaded gasoline is available throughout the USA and Canada. Volkswagen recommends that you do not take your vehicle to places where unleaded gasoline  
may not be available.  
Gasoline containing alcohol or MTBE  
You may use unleaded gasoline blended with alcohol or MTBE (methyl tertiary butyl ether), commonly referred to as oxygenated fuels, if the blended mixture meets  
the following criteria:  
Blends of gasoline and methanol (wood alcohol or methyl alcohol):  
256  
Anti-Knock Index (AKI) must be 87 or higher.  
Blend must contain no more than 3% methanol.  
Blend must contain more than 2% co-solvents.  
Blends of gasoline and ethanol (grain alcohol or ethyl alcohol):  
Anti-Knock Index (AKI) must be 87 or higher.  
Blend must contain no more than 15% ethanol.  
Blends of gasoline and MTBE:  
Anti-Knock Index (AKI) must be 87 or higher.  
Blend must contain no more than 15% MTBE.  
Seasonally adjusted gasoline  
Many fuels are blended especially for winter or summer conditions. When seasons change, Volkswagen suggests that you buy fuel at busy stations where the  
seasonal adjustment is more likely to be made earlier.  
WARNING  
Starting fluids can explode and cause a run-away vehicle condition.  
Never use starting assist fluids.  
NOTE  
Never use fuel with an octane rating lower than 87 AKI/91 RON. Using lower octane fuel may cause expensive engine damage.  
Never use leaded gasoline! Leaded gasoline will severely damage your vehicle's catalytic converter.  
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.  
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.  
Do not use fuels that fail to meet the criteria above, or with contents that cannot be identified.  
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.  
Using fuels that are different from those specified above can damage your vehicle's engine and fuel system and cause performance problems.  
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.  
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  
Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ  
Additives are used to improve the quality of the gasoline.  
Fuel quality impacts the operating performance, efficiency and service life of the engine. Therefore, use high quality gasoline that is already blended by the fuel  
supplier with suitable gasoline additives that do not contain metal. The additives provide corrosion protection, clean the fuel system, and help prevent deposits on  
the engine.  
Volkswagen recommends TOP TIER Detergent Gasoline. For more information on TOP TIER Detergent Gasoline, please go to the official Web site  
.  
If quality gasoline with additives that do not contain metal is not available or engine malfunctions occur, you should add the required additives while refueling  
⇒
Not all gasoline additives are effective. Using the wrong additives can cause significant and expensive damage to the engine and the catalytic converter. Never use  
additives that contain metal. Please note that metal can be included in some aftermarket gasoline additives that are available to be added to gasoline during or afte  
refueling to help improve knock resistance or increase the octane rating.  
Volkswagen recommends using only additives approved by Volkswagen. Appropriate additives as well as instructions on how to use them are available from your  
authorized Volkswagen dealer or authorized Volkswagen Service Facility. Do not add any other gasoline additives.
