Lexus RX Owners Manual (RX450h): Lexus Safety System+

The Lexus Safety System+ consists of the following drive assist systems and contributes to a safe and comfortable driving experience:

• PCS (Pre-Collision System)
• LKA (Lane-Keeping Assist)
• Automatic High Beam
• Dynamic radar cruise control with full-speed range

WARNING

■ Lexus Safety System+ The Lexus Safety System+ is designed to operate under the assumption that the driver will drive safely, and is designed to help reduce the impact to the occupants and the vehicle in the case of a collision or assist the driver in normal driving conditions.

As there is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. The driver is always responsible for paying attention to the vehicle's surroundings and driving safely.

Vehicle data recording

The pre-collision system is equipped with a sophisticated computer that will record certain data, such as:

• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distance and relative speed between your vehicle and the vehicle ahead or other objects)
• Images from the camera sensor (available only when the pre-collision braking function or the pre-collision brake assist function was operating)

The pre-collision system does not record conversations, sounds or images of the inside of the vehicle.

• Data usage
  Lexus may use the data recorded in this computer to diagnose malfunctions, conduct research and development, and improve quality.

  Lexus will not disclose the recorded data to a third party except:

  • With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
  • In response to an official request by the police, a court of law or a government agency
  • For use by Lexus in a lawsuit
  • For research purposes where the data is not tied to a specific vehicle or vehicle owner
• Recorded images can be erased using a specialized device.

  The image recording function can be disabled. However, if the function is disabled, data from when the pre-collision system operates will not be available.

Sensors

Two types of sensors, located behind the front grille and windshield, detect information necessary to operate the drive assist systems.

1. Radar sensor
2. Camera sensor
