Bags are placed in the front, mounted in the seats against lateral impact, and present in the curtain and knee positions. (Knee bags are for the driver and front passenger only.) Onboard systems monitor traction, stability, braking, and tire pressure. Beams in the doors absorb and dissipate force as does the upper interior trim.
