How does the Lexus pre-Collision System work?
The Lexus Pre-Collision System is an advanced safety feature that uses radar and camera sensors to detect potential collisions and automatically apply the brakes to help avoid or mitigate the impact. This system is designed to enhance driver awareness and provide an extra layer of protection for Lexus vehicle occupants.
How the System Operates
The Lexus Pre-Collision System continuously monitors the road ahead using a front-facing radar sensor and a monocular camera. These sensors work together to detect vehicles, pedestrians, and other obstacles in the vehicle's path. If the system determines that a collision is imminent, it will take the following actions:
- Provide a visual and audible alert to the driver to prompt them to take evasive action.
- Prepare the braking system by increasing brake fluid pressure, which helps improve brake responsiveness.
- If the driver does not respond, the system will automatically apply the brakes to help slow the vehicle and reduce the impact force of the collision.
The system is designed to work at speeds between approximately 7 and 110 mph, and it can detect vehicles, pedestrians, and cyclists. The system's effectiveness is dependent on various factors, including the speed of the vehicles involved, the angle of the collision, and the type of obstacle detected.
Additional Features
The Lexus Pre-Collision System also includes the following advanced features:
- Pedestrian Detection: The system can detect pedestrians and cyclists and apply the brakes to help avoid or mitigate collisions with them.
- Intersection Support: The system can detect vehicles approaching from the side at intersections and apply the brakes to help avoid collisions.
- Adaptive Cruise Control: The system can maintain a safe following distance from the vehicle in front, and it can automatically adjust the vehicle's speed to maintain that distance.
Overall, the Lexus Pre-Collision System is a comprehensive safety feature that uses advanced sensors and algorithms to help protect vehicle occupants and other road users. By providing early warning and automatic braking, the system can help reduce the severity of collisions or even prevent them altogether.
How does the collision warning system work?
What Is It? Forward collision warning systems warn you of an impending collision by detecting stopped or slowly moved vehicles ahead of your vehicle. Forward collision warning use radar, lasers, or cameras to scan the road ahead while you drive.
Does Lexus have automatic braking?
If your vehicle detects a frontal collision is possible, it's designed to use Brake Assist to apply pressure to the brakes for you. In certain instances, Brake Assist can automatically bring your Lexus to a stop for you.
Why does my pre-collision light keep coming on?
Understood, so both the adaptive cruise control and the pre-collision assist rely on a front radar sensor, referred to as the CCM that sits behind the front grille. If this sensor gets damaged or wet it can throw off its calibration and disable both of those systems which then turns on those warning messages.
What is the Lexus pre-Collision System?
Pre-Collision System with Pedestrian Detection ensure that you're always best-placed to react to the road ahead. The Pre-Collision System monitors vehicles and pedestrians ahead of your car, sending alerts if a frontal collision is likely and improving your braking capability if a collision is unavoidable.
What is the forward collision warning on a Lexus?
Under certain conditions, if Pre-Collision System with Pedestrian Detection determines that the possibility of a frontal collision with a pedestrian is high, it prompts the driver to take evasive action and brake, by using an audible and visual alert, followed by Brake Assist.
What triggers an automatic collision notification?
The ACN system springs into action when the vehicle detects a collision through airbag deployment or impact sensor trigger. The call center agent will attempt to speak with the vehicle's occupants to assess potential injury and damage.
How do I know if my forward collision warning is working?
When you're approaching a vehicle ahead too quickly and might be seconds away from a potential crash, the system will flash a red Collision Alert on the lower windshield, as well as sound eight high-pitched front beeps.
Where is the pre-collision assist sensor located?
Front bumper area: The pre-collision system typically utilizes sensors located in the front bumper area. Look for any visible damage, loose connections, or dirt/debris that could be obstructing the sensors. Grille area: Some vehicles have sensors embedded in or around the grille.

At what speed is pre-collision assist active?
approximately 3 mph
Pre-Collision Assist is active at approximately 3 mph. Pedestrian Detection is active up to 50 mph. Pedestrian Detection can detect pedestrians, but not in all conditions and does not replace safe driving. See owner's manual for system limitations.
