Modern Chevy Malibu models feature advanced airbag systems designed to deploy within milliseconds (typically 20–30 ms) after sensors detect a significant frontal or side impact. Exact deployment timing varies by model year, impact severity, angle, and whether seat belts are fastened. The system uses algorithms to decide which airbags (frontal, side, curtain, knee) to fire and at what pressure. Airbags are supplemental restraints; they work best combined with seat belts. For model-specific details, consult the owner's manual or a GM dealership.
