WARNING Modifications to or work improperly 
Modifications to or work improperly conducted on restraint system components or their wiring, as well as tampering with interconnected electronic systems, can lead to the restraint systems no longer functioning as intended.
Air bags or Emergency Tensioning Devices/belt buckle tensioners, for example, could deploy inadvertently or fail to deploy.
Therefore, never modify the restraint systems. Do not tamper with electronic components or their software.
