The RX 450h leads its class [1] with a total of 10 airbags [2]. The Supplemental Restraint System (SRS) in the RX 450h includes front seat-mounted side-impact airbags that provide a larger protection area than conventional side airbags. A driver’s dual-stage airbag deploys at one of two speeds, depending on factors like crash severity and driver’s seat-track position. And the front passenger’s dual-stage, twin-chamber airbag uses occupant weight and crash-severity sensors to monitor its deployment. Also included are front and rear roll-sensing side curtain airbags, outboard rear seat-mounted airbags and driver’s and front passenger’s knee airbags.
