Lexus RX (RX 350L, RX450h) 2016-2024 Owners Manual: Brake Hold

The brake hold system keeps the brake applied when the shift lever is in D, S or N with the system on and the brake pedal has been depressed to stop the vehicle.

The system releases the brake when the accelerator pedal is depressed with the shift lever in D or S to allow smooth start off.

The brake hold standby indicator (green) comes on. While the system is holding the brakes, the brake hold operated indicator (yellow) will illuminate.

If either of the conditions above are detected when the brake hold system is enabled, the system will turn off and the brake hold standby indicator light will go off. In addition, if any of the conditions are detected while the system is holding the brakes, a warning buzzer will sound and a message will be shown on the multi-information display. The parking brake will then be set automatically.
