Lexus Safety System+
Relentlessly devoted to your safety, Lexus is introducing an all-new set of advanced safety features known as Lexus Safety System+ (LSS+). Designed to help you prevent collisions, LSS+ scans for hazards and actively works to avoid them using four innovative systems. LSS+ will be available on almost all* 2018/19 vehicles, but you can experience it first on select 2017 models. The Key Features of the Lexus Safety System+- Automatic High Beam (AHB)
- Lane Departure Alert (LDA)
- Dynamic Radar Cruise Control (DRCC)
- Pre-Collision System (PCS)
1. Automatic High Beam (AHB)

Uncomfortable with driving in the dark? AHB is designed to ensure better visibility while you navigate through the night. It uses cameras located on the windshield to detect headlights of oncoming vehicles in front and automatically switches between high and low beams. While your peace of mind will certainly increase, the risk of collision is reduced.
Read disclaimerAutomatic high beam feature can help improve vision at night. However, conditions such as a dirty windshield, rapidly changing light conditions or hilly terrain will limit effectiveness so the driver may need to manually adjust the high beams from on to off. Please see your Owner’s Manual for details.
2. Lane Departure Alert (LDA)

The LDA takes into account that even the most focused drivers can become distracted. If the vehicle begins to deviate from the current lane, the system issues a buzzer sound, a display notification, and a steering wheel vibration to recommend that the driver correct the vehicle’s path.
Read disclaimerLane Departure Alert is designed to read the lane markers under certain conditions, and provide visual and audible alerts when lane departure is detected. It is not a collision-avoidance system or a substitute for safe and attentive driving. Effectiveness depends on many factors. See Owner’s Manual for more information.
3. Dynamic Radar Cruise Control (DRCC)

Using multiple sensors, including the millimetre wave sensor, the DRCC determines the distance of vehicles in front of you and controls your speed within a preset range to match the speed of the other driver. Long highway drives are now less tiring and instances of sudden braking are far less frequent.
Settable distances between cars (when travelling at 80km/h)
- Long: ~ 50 meters
- Medium: ~ 40 meters
- Short: ~ 30 meters
Dynamic/Radar Cruise Control was designed to assist the driver and is not a substitute for safe and attentive driving practices. Please see your Owner’s Manual for important cautions and instructions.
4. Pre-Collision System (PCS)

You can't always anticipate the actions of other drivers. PCS uses sensors to detect other vehicles and obstructions in front of your Lexus. If the system determines a high probability of a collision it will issue a warning. In situations where a collision has been determined to be unavoidable it will automatically apply the brakes.
Key features of millimeter-wave radar sensor include:
- Can detect at distances and at high speeds
- Works well in poor-weather, such as rain, fog and falling snow
- Since it provides excellent object detection, it can detect pedestrians when combined with monocular camera
The Pre-Collision System is designed to help reduce the crash speed and damage in certain frontal collisions only. It is not a collision avoidance system and is not a substitute for safe and attentive driving. System effectiveness depends on many factors, such as speed, driver input and road conditions. Please see your Owner’s Manual for further information.
ADVANCED SAFETY
ELEVATED PEACE OF MIND
Every moment spent behind the wheel of your Lexus, should be one of worry-free joy. That’s why we invest so much in safety technology. Even designing systems that can help prevent accidents before they happen. All to keep you, your passengers, other drivers, and the cyclists and pedestrians who share the roads safer.
LEXUS SAFETY SYSTEM+
THE LUXURY OF CONFIDENCE
Lexus Safety System+, standard on all models, integrates four active safety systems that help to support your awareness and decision-making across a range of speeds and driving conditions. LSS+ 2.0, available on many 2020 and newer models, features a series of enhancements, and adds an additional system that helps keep your vehicle centred in its lane. LSS+ 2.5, introduced on the 2021 IS, further enhances the pre-collision, lane tracing assist, and dynamic radar cruise control systems. LSS+ A, exclusive to the Lexus LS, is our most sophisticated safety system yet – bringing us closer to our vision of an accident-free world.
