Safety precautions for crash sensors (pressure sensors) for side airbag (front)
The crash sensors for side airbags are very sensitive to pressure changes and must therefore be handled with great care. Please note the following:
t  Always pay attention to the correct installation position: Only install at the envisaged fitting location in the door.
t  Protect crash sensors against impact: Crash sensors which have been dropped are not to be re-used. Remove the crash sensor when carrying out work on the door bodywork.
t  The crash sensor is matched to the volume of air inside the door: Operation of the crash sensor will be impaired by deformation of the door which reduces the air space in the door.
t  Avoid contaminating the crash sensors: Do not use compressed air in the vicinity of the crash sensors. Protect the crash sensor against filings or bore chips (example, during retrofitting of door speakers). Do not use cavity sealants or spray oil in the vicinity of the crash sensor.
t  Protection against high/low temperatures: Avoid exposure to heat, for instance when painting or performing other bodywork operations. The crash sensors should not be exposed to temperatures below -40 °C (e.g. in a non-air-conditioned loading area of a vehicle) or above 100 °C (e.g. in a varnish cell).
t  The crash sensor must be protected against moisture, both during storage and when installing.
Ensure that the door is properly sealed when it is installed; otherwise the crash sensor may not function correctly. Please note the following:
t  All components (e.g. cover, loud speaker, door lining) must be mounted correctly.
t  The retaining clips of the door lining seal the system. If necessary, renew retaining clips.
