Your car is equipped with a pretty advanced sensing system designed to determine whether a front passenger is present, and whether they are of adult size or not, called the front passenger occupant classification system. Here’s how it works:

  • The system determines the weight and size of the person in the front passenger seat.

  • The system determines whether anyone is sitting in the seat at all (large, heavy items like briefcases, large laptops and suitcases can cause a false positive).

  • Based on the information from the sensors, the system will turn the passenger front air bag light on or off, deactivate the passenger air bags, and turn the passenger seat belt reminder light on or off.
