■Operational conditions
Availability of the pedestrian detection function and pre-collision braking function
depend on the region in which the vehicle was sold.
Read the following for details:
Region A (The pedestrian detection function and pre-collision braking function are available)
The pre-collision system is enabled and the sy stem determines that the possibility of a
frontal collision with a vehicle or pedestrian is high.
Each function is operationa l at the following speeds:
●Pre-collision 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-collision brake assist:
• Vehicle speed is between approximately 30 and 180 km/h (19 and 110 mph). (For
detecting 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-collision 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 12-volt battery terminal has been disconnected and reconnected and then the vehi-
cle has not been driven for a certain amount of time
●If the shift lever is in R
●If VSC is disabled (only the pre-collis ion warning function will be operational)
●If the PCS warning light is flashing or illuminated
RegionsFunction availability

Region BThe pedestrian detection function is not available and the pre-
collision braking function is available
Region CThe pedestrian detection func tion and pre-collision braking
function are not available

Region B
(The pedestrian detection function is not available and the pre-collision braking func- tion is available)
The pre-collision system is enabled and the sy stem determines that the possibility of a
frontal collision with a vehicle is high.
Each function is operationa l at the following speeds:
●Pre-collision warning:
• Vehicle speed is between approximately 15 and 180 km/h (10 and 110 mph). • The relative speed between your vehicle and the vehicle ahead is approximately 10
km/h (7 mph) or more.
●Pre-collision brake assist:
• Vehicle speed is between approximately 30 and 180 km/h (19 and 110 mph).
• The relative speed between your vehicle and the vehicle ahead is approximately 30 km/h (19 mph) or more.
●Pre-collision braking:
• Vehicle speed is between approximately 15 and 180 km/h (10 and 110 mph).
• The relative speed between your vehicle and the vehicle ahead is approximately 10
km/h (7 mph) or more. The system may not operate in the following situations:
●If a 12-volt battery terminal has been disconnected and reconnected and then the vehi-
cle has not been driven for a certain amount of time
●If the shift lever is in R
●If VSC is disabled (only the pre-collis ion warning function will be operational)
●If the PCS warning light is flashing or illuminated

Region C
(The pedestrian dete ction function and pre-collision braking function are not avail- able)
The pre-collision system is enabled and the sy stem determines that the possibility of a
frontal collision with a vehicle is high.
Each function is operationa l at the following speeds:
●Pre-collision warning:
• Vehicle speed is between approximately 15 and 180 km/h (10 and 110 mph). • The relative speed between your vehicle and the vehicle ahead is approximately 10
km/h (7 mph) or more.
●Pre-collision brake assist:
• Vehicle speed is between approximately 30 and 180 km/h (19 and 110 mph).
• The relative speed between your vehicle and the vehicle ahead is approximately 30 km/h (19 mph) or more.
The system may not operate in the following situations:
●If a 12-volt battery terminal has been disconnected and reconnected and then the vehi- cle has not been driven for a certain amount of time
●If the shift lever is in R
●If VSC is disabled (only the pre-collis ion warning function will be operational)
●If the PCS warning light is flashing or illuminated

■If the PCS warning light flashes and a warning message is displayed on the multi-infor-
mation display
The pre-collision system may be temporarily unavailable or there may be a malfunction
in the system.
●In the following situations, the warning light will turn off, the message will disappear and the system will become operational when normal operating conditions return:
• When the radar sensor or camera sensor or the area around either sensor is hot,
such as in the sun • When the radar sensor or came ra sensor or the area around either sensor is cold,
such as in an extremely cold environment
• When the radar sensor or front grille embl em is dirty or covered with snow, etc. • When the part of the windshield in front of the camera sensor is fogged up or cov-
ered with condensation or ic e (Defogging the windshield: P. 474)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the camera sensor
●If the PCS warning light continues to flash or the warning message does not disappear, the system may be malfunctioning. Have the vehicle inspected by any authorized Lexus
retailer or Lexus authoriz ed repairer, or any reliable repairer immediately.
■If VSC is disabled
●If VSC is disabled (P. 354), the pre-collision brake assist and pre-collision braking
functions are also disabled.
●The PCS warning light will turn on and “VSC Turned Off Pre-Collision Brake System Unavailable” will be displayed on the multi-information display.
