Pre Crash Sensors

In the event of an accident, intelligent sensors are designed to trigger off restraint systems for you and your passengers at the right moment. At the heart of this system is the airbag control unit which decides whether restraint systems should be deployed and ignites the airbags and belt tensioners accordingly. Two remote sensors allow the system to determine the pattern and severity of a head-on collision very quickly. These sensors, which measure acceleration, are located in your car's front impact-absorbing zone. They supply signals to the control unit. The rate of deceleration as measured in the central control unit is used as a further source of information for determining the severity of the impact.
