Where is the Lexus active braking function button located?

Lexus active braking function switch button is located above the accelerator and brake pedals, you can see it by crouching down. Active braking belongs to the car safety system. The active braking system can realize automatic alarm, automatic deceleration, and automatic braking when obstacles appear in front of the vehicle and pose a threat to the safe driving of the vehicle, minimizing the risk of collision and achieving active collision prevention. The product can effectively reduce rear-end accidents caused by emergencies, fatigue driving, lack of concentration, and less driving experience. Automatic braking system usage conditions: Active braking works in emergency braking state. Active braking is developed on the basis of ABS, which is the brake assist system BAS. It determines whether to enter the emergency braking state by monitoring the strength and speed of the driver stepping on the brake. If BAS judges that it is necessary to enter the emergency braking state, the system will increase the braking force to achieve the purpose of reducing the braking distance. The automatic braking system in the initial stage requires the driver to find an emergency and step on the brake to start the braking assist, otherwise it will not work. The system determines possible potential collisions through the vehicle in front or possible obstacles. The active braking system will issue a warning sound to remind the driver to pay attention and prepare sufficient braking force in advance. As long as the driver steps on the brake, the braking will exert the maximum braking effect.
As a frequent tinkerer with Lexus vehicles, let me share the location of the active braking function button. It's not a traditional manual brake button per se, but rather the setup key for the Pre-Collision System (PCS), typically located in the multifunction button area on the steering wheel. Specifically, on the left or right side of the steering wheel, you'll find a button with a car front and wavy line icon—that's the control access point. Pressing it will display a menu on the instrument cluster screen, allowing you to turn it on/off or adjust sensitivity. Different models vary: for example, the ES series usually positions it on the left side near cruise control, while the RX might place it in the vehicle settings option on the center touchscreen. I recommend consulting the owner's manual during first use since the button location can be easily overlooked. This feature is auto-activated and only functions at specific speeds to enhance driving safety. Additionally, regularly check the button's contact condition to avoid accidentally disabling the system and affecting emergency braking. Overall, it's designed with user-friendliness in mind to help reduce accident risks.
I've been driving a Lexus for several years and noticed that the active braking button isn't very conspicuous. It's hidden among the buttons on the steering wheel, mostly in the left area, with a small icon resembling a car hitting something - that's the pre-collision system switch. Pressing it brings up a menu to set sensitivity to high, medium, or low. Don't worry about it being a manual button, as the actual braking is automatically triggered. The location varies by model: newer NX might have it in the screen menu, while older IS models place it at the lower right of the steering wheel. I always confirm the system is on before driving, especially in foggy conditions. Pro tip: avoid accidentally pressing the button to prevent deactivation; have technicians check the wiring during regular maintenance. This feature is excellent for preventing rear-end collisions, but I prefer maintaining a safe distance. In short, finding it isn't difficult - just spend some time familiarizing yourself with it.
