The pre-crash seat belt tightens the seat belt with a motor to help restrain front seat occupants. This helps reduce the risk of injury in a collision. The motor retracts the seat belt under the following emergency conditions:

► During emergency braking
► During sudden steering maneuvers
► Activation of the Intelligent Brake Assist (IBA) system. (See “Intelligent Brake Assist (IBA) system” in the “5. Starting and driving” section.)
► In the event of a high severity rollover collision.

The pre-crash seat belt will not be active when:

► the seat belt is not fastened
► the vehicle speed is under 10 MPH (15 km/h) during emergency braking
► the vehicle speed is under 19 MPH (30 km/h) during sudden steering maneuvers or in the event of a high severity rollover collision.

The pre-crash seat belt will not be active when the brake pedal is not depressed except when sudden steering maneuvers occur or the Intelligent Brake Assist (IBA) system activates. The motor also retracts the seat belt when the seat belt is fastened or unfastened. When the seat belt is fastened, the motor tightens the seat belt for a snug fit. When the seat belt is unfastened, the motor retracts the seat belt. If the seat belt is not fully retracted, the motor retracts the seat belt when the door is opened.

Always wear your seat belt correctly and sit upright and well back. If the motor cannot retract the seat belt when the seat belt is fastened or unfastened, it may indicate the pre-crash seat belt system has a malfunction. Have your INFINITI retailer check and repair the system. When the seat belt is retracted repeatedly in a short period of time, the motor may not be able to retract the seat belt. After 8 minutes, the motor reactivates and retracts the seat belt. If the seat belt still cannot be retracted by the motor, the pre-crash seat belt system has a malfunction. Have your INFINITI retailer check and repair the system.
