PCS (Pre-Crash Safety system)∗
◆Pre-crash 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-crash 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-crash safety 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 dr iver to take evasive action and the
potential brake pressure is increased to help the driver avoid the collision. If
the system determines that the 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 reduce the impact of the collision.
The pre-crash safety system can be disabled/enabled and the warning timing
can be changed. ( →P. 2 9 6 )
*1: Depending on the region in which the vehicle was sold, the pedestrian detection
function may not be available. Contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional for details.
*2: Depending on the region in which the vehicle was sold, the pre-crash braking func-tion (automatic braking function) may not be available. Contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional for
details.

■Enabling/disabling the pre-crash safety system
The pre-crash safety system can be enabled/disabled on ( →P. 1 2 1 ,
129) of the multi-information display.
The system is automatically enabled each ti me the engine switch is turned to IGNI-
TION ON mode.
If the system is disabled, the PCS
warning light will turn on and a mes-
sage will be displayed on the multi-
information display.
■Changing the pre-crash warning timing
The pre-crash warning timing can be changed on ( →P. 121, 129) of
the multi-information display.
The operation timing setting is retained when the engine switch is turned off.
Fa r
The warning will begin to operate
earlier than with the default timing.
Middle
This is the default setting.
Near
The warning will begin to operate
later than with the default timing.

■Operational conditions
Availability of the pedestrian detection function and pre-crash braking function depend
on the region in which the vehicle was sold.
Read the following for details:
XRegion A
(The pedestrian detection function and pre-crash braking function are available)
The pre-crash safety system is enabled and th e system determines that the possibility of a
frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:
●Pre-crash warning:
• Vehicle speed is between approximately 10 and 180 km/h (7 and 110 mph). (For detecting a pedestrian, vehicle speed is between approximately 10 and 80 km/h [7
and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 10 km/h (7 mph) or more.
●Pre-crash brake assist:
• Vehicle speed is between approximately 30 and 180 km/h (19 and 110 mph). (Fordetecting a pedestrian, vehicle speed is between approximately 30 and 80 km/h
[19 and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 30 km/h (19 mph) or more.
●Pre-crash braking:
• Vehicle speed is between approximately 10 and 180 km/h (7 and 110 mph). (For
detecting a pedestrian, vehicle speed is between approximately 10 and 80 km/h [7
and 50 mph].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is
approximately 10 km/h (7 mph) or more.
The system may not operate in the following situations:
●If a battery terminal has been disconnected and reconnected and then the vehicle has
not been driven for a certain amount of time
●If the shift lever is in R
●If VSC is disabled (only the pre-crash warning function will be operational)
●If the PCS warning light is flashing or illuminated
