Lexus Safety System+

Lane Departure Alert with Steering Assist (LDA)

On Lexus vehicles equipped with LSS+, Lane Departure Alert (LDA) recognizes if your vehicle is deviating from its current lane, and signals you to take action with both an audible alert and steering wheel vibrations. The Steering Assist function may also provide small corrective steering inputs.

Lane Tracing Assist (LTA)

Lexus vehicles equipped with LSS+ 2.0 add Lane Tracing Assist (LTA) that brings improved lane marking recognition and lane centering capabilities, and operates when Dynamic Radar Cruise Control (DRCC) is activated. Together, LDA and LTA work to prevent accidents caused by a momentary lapse of concentration brought on by fatigue or inadvertent loss of focus.

Active Steering Assist (ASA)

Exclusive to Lexus LS, Active Steering Assist (ASA) helps prevent collisions that cannot be avoided through automatic braking alone by automatically steering around obstacles for you.

High-Speed Dynamic Radar Cruise Control (DRCC)

Lexus vehicles equipped with LSS+ feature a High-Speed Dynamic Radar Cruise Control System (DRCC). The system is designed to operate between speeds of approximately 40 km/h to 180 km/h and enables you to maintain a comfortable, constant driving speed or a preset vehicle to vehicle following distance -- automatically maintaining a sufficient distance between you and a preceding vehicle.

Full-Speed Dynamic Radar Cruise Control (DRCC)

Vehicles equipped with LSS+ 2.0 feature Full-Speed Dynamic Radar Cruise Control (DRCC), can perform vehicle-to-vehicle distance control down to 0 km/h, and resume from a complete stop. All of which means that long drives can now be less tiring, and the need for sudden braking less frequent.

Pre-Collision System with Daytime Pedestrian Detection (PCS)

On Lexus vehicles equipped with LSS+, the Pre-Collision System (PCS) monitors vehicles and pedestrians in front of your Lexus. If the system determines a high probability of a collision it issues a warning. In situations where a collision has been determined to be unavoidable PCS automatically applies the brakes to help prevent or mitigate a collision.

Pre-Collision System with Pedestrian (low-light) and Daytime Bicycle Detection

On vehicles equipped with LSS+ 2.0, PCS has been enhanced -- with an increase in the radar’s sensitivity and dynamic range -- so that it can better detect pedestrians in low-light situations, as well as bicycles in daytime situations.
