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 capacitive passenger detection system 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 manufac-tured.
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 characteris-tics 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 pas-senger 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 pas-senger 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.
Therefore we strongly recommend that you use your cellular 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 cellular telephones on the market and the frequency with which new models are introduced, Volkswagen does not offer cradles for cellular telephones. Please check with the manufacturer of the cellular 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 brack-ets, note pads, navigation systems, large, heavy or bulky objects) on the doors, on the wind-shield, 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.
WARNING
Using a mobile phone or CB radio inside the vehicle without a properly installed and separate outside antenna can be dangerous to your health and that of your passengers because the electromagnetic radiation energy that mobile phones and CB radios emit may be above es-tablished limits. This also applies if the outside antenna is not installed properly.
x Always keep the mobile phone antenna at least 8 in (20 cm) away from pacemakers. Heart specialists advise that mobile phones can adversely affect the way pacemakers work.
x Never carry a mobile phone that is switched on in the breast pocket directly over a pace-maker.
x If you suspect there may be interference with a pacemaker or other medical device, switch the mobile phone off immediately.
