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.
x Have the airbag system inspected immediately by your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
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.
NOTICE
x Do not soak Alcantara®.
x Do not treat Alcantara® with leather care products, solvents, floor wax, shoe polish, stain remover or similar products.
x Do not use brushes for damp cleaning, because they can damage upholstery surfaces.
x Do not use a steam cleaner, because dirt will penetrate deeper into the fabric.

WARNING
Damage to safety belts reduces their overall effectiveness and increases the risk of serious personal injury and death whenever the vehicle is being used.
x Check the condition of all safety belts regularly. If you notice that the safety belt webbing, hardware, retractor, buckle, or any other part of the safety belts is damaged, immediately have an authorized Volkswagen dealer or authorized Volkswagen Service Facility replace the safety belt with the correct replacement belt for your vehicle model and model year.
x Never use chemical cleaning agents, solvents, or any substance that may damage or weaken the safety belt webbing or any other parts of the safety belt. Never let the belts come into contact with corrosive fluids or sharp objects. Otherwise, the safety belt webbing will be significantly weakened.
x After cleaning, always give the safety belts time to dry completely before letting them retract. The moisture can damage the retractor and keep it from working properly.
x Never let foreign objects or liquids get into the safety belt latch. This could prevent the belt buckles and safety belts from working properly.
x Damaged safety belts must be replaced; they cannot be repaired.
x Never try to repair a damaged safety belt yourself. Never remove or modify the safety belts in any way.
x Safety belts that were subject to stress in an accident and stretched must be replaced with a correct, new safety belt, preferably by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
x Replacement after a crash may be necessary even if a safety belt shows no visible damage. Anchorages that have been loaded must also be inspected.

WARNING
Inappropriate spare parts and accessories as well as improperly performed work, modifications and repairs can cause vehicle damage, accidents and serious personal injuries.
x Volkswagen strongly recommends to only use accessories approved by Volkswagen and Genuine Volkswagen Parts®. These parts and accessories have been evaluated by Volkswagen for their suitability, reliability and safety.
x Have repairs and vehicle modifications performed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Authorized Volkswagen dealers and authorized Volkswagen Service Facilities have the required tools, diagnostic equipment, repair information, and trained personnel to properly replace any airbag in your vehicle and assure system effectiveness in a crash.
x Only install parts on the vehicle that are consistent with factory-installed parts with respect to design and characteristics.
x Never store, mount, or attach objects, such as cup holders or phone cradles, on or next to the airbag module covers or within the airbags deployment zones.
x Only use wheel rim/tire combinations approved by Volkswagen for the respective vehicle type.
Break-in period

WARNING
Improper care and servicing, and improper modification and repair work, can increase the risk of personal injury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
x Never repair, adjust, or change any parts of the airbag system.
x All work on the airbag system, steering wheel, instrument panel, front seats or electrical system (including the installation of audio equipment, mobile telephones and CB radios, etc.) should be performed by authorized Volkswagen dealers or authorized Volkswagen Service Facilities. They have the necessary manuals, training, and special equipment.
x The airbag system can be activated only once. After an airbag has inflated, it must be replaced.
x Use only original equipment airbags approved by Volkswagen. Have them installed by a trained technician who has the necessary tools and diagnostic equipment to properly replace any airbag in your vehicle and assure system effectiveness in a crash.
x Never permit salvaged or recycled airbags to be installed in your vehicle.

human body. Limits and guidelines have been established by governmental authorities and international committees in an effort to keep the electromagnetic radiation from mobile phones at levels that will not cause health problems. However, there is no scientifically based proof that wireless phones are absolutely safe.
Therefore, some experts recommend a precautionary approach regarding the use of mobile phones by taking measures that lower the personal exposure to electromagnetic fields. When using a mobile telephone inside a motor vehicle without a proper connection to an integrated vehicle telephone antenna, the personal exposure to electromagnetic fields will be higher than when using the mobile telephone while properly connected to an integrated or other outside vehicle telephone antenna.
Your vehicle may be equipped with an optional hands-free system that will permit many of the features of compatible Bluetooth® enabled mobile telephones to be used for greater convenience and is consistent with the laws of an increasing number of states and localities that prohibit the use of mobile telephones without some kind of hands-free device.
The hands-free system in your vehicle can be used with certain mobile phones that are connected by wire and hardware connector or via compatible Bluetooth® enabled phones with a cradle that is designed to fit your mobile telephone. The special cradle offers several advantages: The phone cradle must be safely secured to the base plate. Your phone is firmly attached to the instrument panel and is within reach at all times. Placing the phone in its cradle permits it to be charged, but more importantly connects the mobile phone to the vehicle's outside antenna. A mobile telephone that is properly connected to the integrated or other outside vehicle telephone antenna will lower the personal exposure to electromagnetic fields. You should also experience a better quality of service. Although a mobile telephone can be used inside your vehicle without a cradle, the phone will not be securely attached to the vehicle, will not be charged through the cradle wiring, and more importantly will not be connected to the vehicle's integrated telephone antenna. The mobile phone will also not be recharged. You might also experience more dropped calls and an overall impaired quality of the connection.
Therefore we strongly recommend that you use your mobile telephone in your vehicle only when it is properly attached to an appropriate cradle mounted on a base plate on the instrument panel.
Because of the large number and variety of mobile telephones on the market and the frequency with which new models are introduced, Volkswagen does not offer cradles for mobile telephones. Please check with the manufacturer of the mobile telephone that you plan to use.

WARNING
A mobile phone on the seat, instrument panel or in other places can be thrown around the inside of the vehicle during a sudden braking maneuver, a crash or other accident and injure vehicle occupants.
x Never place or attach accessories or other objects (such as cup holders, telephone brackets, note pads, navigation systems, large, heavy or bulky objects) on the doors, on the windshield, over or near the area marked “AIRBAG” on the steering wheel, instrument panel, backrests or between these areas and the occupant. Such objects could cause serious injury in a collision, especially if an airbag inflates.

x Fuel may have a considerably lower octane rating and may cause engine damage.
x Service may be inadequate due to lack of proper service facilities, tools or testing equipment.
x Replacement parts may not be readily available.
x DVD navigation systems for vehicles built for the United States and Canada will not necessarily work in Europe, and may not work in other countries outside of North America.
NOTICE
Volkswagen is not responsible for mechanical damage that may result from substandard fuel or service or the unavailability of Genuine Volkswagen parts.
x Volkswagen is not responsible if the vehicle does not meet the respective legal requirements in other countries and continents.

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.
