WA R N I N G
■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 responsi-
ble for paying attention to the vehicl e’s surroundings and driving safely.

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 was operating)
The pre-collision system does not record conversations or other sounds and
does not record 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 govern- ment 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 information recording function can be disabled. However, if the
function is disabled, data from when the pre-collision system operates will not
be available.

PCS (Pre-Collision System)
◆Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.
◆Pre-collision brake assist
When the system determines that the possibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.
: If equipped
The pre-collision system uses a radar sensor and camera sensor to detect
vehicles and pedestrians
*1 in front of your vehicle. When the system deter-
mines that the possibility of a frontal collision with a vehicle or pedestrian is
high, a warning operates to urge the driver to take evasive action and the
potential brake pressure is increased to help the driver avoid the collision. If
the system determines that th e possibility of a frontal collision with a vehicle or
pedestrian is extremely high, the brakes are automatically applied
*2 to help
avoid the collision or help redu ce the impact of the collision.
The pre-collision system can be disabl ed/enabled and the warning timing can
be changed. ( P. 2 2 3 )
*1: Depending on the region in which the vehicle was sold, the pedestrian detection
function may not be available. Contact your Lexus dealer for details.
*2: Depending on the region in which the vehicle was sold, the pre-collision brakingfunction (automatic braking function) may not be available. Contact your Lexus
dealer for details.
