WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious person-al injuries.
x Always make sure all windows are clear of ice, snow and condensation for good visibility to the front, sides, and rear.
x Maximum heating output and defrosting performance are not possible until the engine has reached operating temperature. Wait until you have good visibility before driving off.
x Always make sure you know how to properly use the climate control system as well as the rear window defroster that you will need for good visibility.
x Never use air recirculation for long periods of time. 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.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents, colli-sions and serious personal injury.
x Never switch off the fan for a long period of time and never use air recirculation for a long period of time because no fresh air will enter the passenger compartment.
NOTICE
x If you think the air conditioner is not working properly or may be damaged, switch it off to help prevent more damage. Have the air conditioner checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
x Air conditioner repair requires specialized knowledge and special tools. Volkswagen rec-ommends that you see an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
x Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation sys-tem can leave residue on the evaporator and on the dust and pollen active carbon filter, result-ing in permanent odors whenever the air conditioner is switched on.
If the air conditioner is switched off, the fresh outside air will not be dehumidified. To help keep the windows from fogging over, Volkswagen recommends leaving the air conditioner (compressor) switched on. Press the !

Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle battery has been replaced may change or delete system settings (including time, date, personal con-venience settings, and programming). Check the settings and correct as necessary once the vehicle battery has built up a sufficient charge.

WARNING
Even if empty, portable fuel containers can leak and cause a fire and serious personal inju-ries, especially in a crash.
x For your safety, we strongly recommend that you do not travel with a portable fuel con-tainer 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 exam-ple, in the luggage compartment or on top of the luggage compartment lid). Static electric-ity 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 dur-ing 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 transpor-tation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as AN-SI/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.

slightly with light pressure to open the misfueling guard. If the misfueling guard cannot be opened this way, see the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility and have the fuel system checked.
WARNING
Spilled fuel can cause fires, explosions, burns, and other severe injuries.
x Do not refuel from devices other than correct, undamaged standard diesel fuel pump noz-zles.
x Always stop refueling once the pump nozzle switches off so that the tank does not over-flow.
NOTICE
x It is your responsibility to put the right fuel in your vehicle and any damage that results from using the wrong fuel is not covered under the Emissions warranties or any other Volkswagen Limited Warranty.
x If you put any amount of the wrong 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.
NOTICE
Never force a fuel nozzle in the diesel misfueling guard. Forcing a fuel nozzle in the misfueling guard can damage it so that it can no longer help prevent misfueling.
x If you have problems inserting a diesel fuel nozzle, please check to make sure you are using the right kind of diesel fuel.
x If you must refuel with a non-standard diesel fuel nozzle, an adapter is available from Volkswagen to allow refueling. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance. Only use an adapter approved by Volkswagen for your vehicle.
x Remember that the nozzle on a portable fuel container will generally not open the misfueling guard. If you must refuel with a portable fuel container in an emergency, you can pour diesel fuel very slowly from a portable container into the fuel filler neck of your vehicle. The fuel will flow slowly past the misfueling guard and into the tank.
Fuel capacities

Octane rating
Octane rating indicates a gasoline's ability to resist engine-damaging “knock” caused by pre-ignition. Using the correct grade of gasoline is very important to help prevent engine damage and loss of engine performance.
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.
If unleaded Premium grade gasoline is specified for your vehicle, then Volkswagen recommends using TOP TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95 RON). For more infor-mation on TOP TIER Detergent Gasoline, please go to the official Web site, http://www.toptiergas.com.
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:
x Premium grade: 91 to 96 AKI
x Regular grade: 87 to 90 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):
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 3% methanol.
x Blend must contain more than 2% co-solvents.
Blends of gasoline and ethanol (grain alcohol or ethyl alcohol):
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 15% ethanol.
Blends of gasoline and MTBE:
x Anti-Knock Index (AKI) must be 87 or higher.
x 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.
x Never use starting assist fluids.
NOTICE
x Never use fuel with an octane rating lower than 87 AKI/91 RON. Using lower octane fuel may cause expensive engine damage.
x Never use leaded gasoline! Leaded gasoline will severely damage your vehicle's catalytic converter.

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 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.
