In response to media stories of vehicle acceleration, Lexus has released this video clarifying the stopping procedure for hybrid models:
From this video, it is made clear that:
- 1) All Lexus hybrids have a brake override system, which cuts power to the engine when the accelerator and brake pedals are simultaneously pressed.
- 2) Lexus vehicles can be shifted into neutral at any time (for the HS, holding the joystick at N for a second is needed).
- 3) As a last resort, the push-button ignition can be held for 3 seconds to cut off engine power (power steering and brake assist will also be removed, but the brakes and steering will still work with more effort).
Overall, the most sensible option in any unintended acceleration incident, in any car, is to shift to neutral and brake firmly.
