CRV models have special safety features called Supplemental Restraint System (SRS) airbags. These blow up automatically to keep drivers and passengers safe when they crash. The system involves numerous airbag components, crash monitors, a control center, and seat belt technology, all controlled by electrical signals sent from the vehicle's front impacts. Each airbag module has a case surrounding a cushion and a small gas releasing device. When it gets power from an electrical signal, it rapidly fills up with air. The control unit uses a built-in processor to check system health at vehicle startup and watch over system functions. Before airbags inflate, impact sensors must activate the electrical circuit that makes them work. When you turn on the ignition, a self-check circuit shows a light on the dashboard to show how well the system works. Take care while fixing items close to the SRS system because regular airbag wires appear bright yellow and need to stay untouched. To stop the airbags from activating, first position the steering wheel straight ahead. Then turn the ignition all the way to the locked position before disconnecting the negative battery cable. The system's operation needs turning on the ignition first, and watching the airbag indicator. Drivers need to remove the steering wheel before changing the driver's side airbag module and clock spring, but the passenger's side airbag module is simpler to work on - just disconnect the electrical connector and free its mounting nuts. A licensed professional must replace or repair side-impact airbags when service is required. The front seat belt retractors in every model use small explosive devices that quickly pull the seat belts tighter when the car meets with an impact.
