Waxing and polishing vehicle paint

Changing the vehicle's suspension system can change the way that the airbag system works in a crash. For example, using tire-rim combinations not approved by Volkswagen, lowering the vehicle, changing the stiffness of the suspension, including the springs, suspension struts, shock absorbers etc. can change the forces that are measured by the airbag sensors and sent to the electronic control unit. Some suspension changes can, for example, increase the force levels measured by the airbag sensors and sent to the electronic control unit and make the airbag system deploy in crashes in which it would not deploy if the changes had not been made. Other kinds of changes may reduce the force levels measured by the sensors and prevent the airbag from deploying when it should.
Never install leather upholstery on a vehicle that originally had cloth upholstery. Never install cloth upholstery on a vehicle that originally had leather upholstery. The weight-sensing mat for the Advanced Airbag system will not work properly if different upholstery is installed on the passenger seat than the upholstery originally installed on the vehicle when it was originally manufactured.
WARNING
Changing the vehicle's suspension including use of unapproved tire-rim combinations can change airbag performance and increase the risk of serious personal injury in a crash.
x Never install suspension components that do not have the same performance characteristics as the components originally installed on your vehicle.
x Never use tire-rim combinations that have not been approved by Volkswagen.
WARNING
Leaving the optional safety belt extender attached to the safety belt buckle on the front passenger seat when the safety belt is not being used will prevent the Advanced Airbag System from working properly and can increase the risk of serious personal injury in a collision.
x Leaving the extender attached to the safety belt buckle when the front seat is occupied and the safety belt is not being used will signal to the airbag control unit that the front passenger seat is occupied and that the safety belt is being used. The electronic control unit for the airbag system will then receive incorrect information that will
– cause the safety belt pretensioner to deploy unnecessarily in collisions and
– cause the front passenger airbag to deploy later in collisions in which the front airbag would otherwise be triggered earlier to help protect an unrestrained front seat passenger.
x Always remove the safety belt extender when it is not needed and stow it safely.
x Never use the safety belt extender to secure a child restraint.
WARNING
Items stored between the safety belt buckle and the center console can cause safety belt buckle to send the wrong information to the airbag control unit and prevent the Advanced Airbag System from working properly.
x Always make sure that nothing can interfere with the safety belt buckles and that they are not obstructed.

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 phone 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
Improper replacement of burned out headlights and other light bulbs can cause serious personal injury.
x Stop! Always read and heed the WARNINGS before doing any work in the engine
compartment ⇒ Working in the engine compartment. The engine compartment of any motor vehicle is a potentially dangerous area, and work in this area can lead to serious personal injury.
x HID – High Intensity Discharge (Xenon) get power from a high voltage source that can cause severe personal injury and even death if handled improperly.
x H7/H15 bulbs and HID – High Intensity Discharge (Xenon) are under high pressure and can explode if handled improperly.
x Always let a burned out light bulb cool down before replacing it.
x Never replace a light bulb unless you are familiar with all of the necessary procedures. In particular, never remove a headlight unless you know exactly how to carry out the job and have the correct tools and light bulbs.
x If you are uncertain about what to do, have the work performed by an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon) lamps and H7/H15 bulbs replaced by a qualified technician.
x Do not touch the glass of light bulbs with your bare hands. Fingerprints left on the bulb evaporate due to the heat when the bulb is switched on and cause the reflector to “cloud”.
x There are sharp edges on and around the headlight housing in the engine compartment and the rear light housing. Wear hand protection if you replace bulbs.
NOTICE
After replacing a headlight bulb or other light bulb, always make sure that the rubber covers or plastic caps have been properly and securely reinstalled to help prevent water from getting into the electrical connections and headlight housing and damaging the electrical system.
