Conditions that may trigger the system even if there is no possibility of a collision
When there is an object by the roadside at the entrance to a curve
When passing an oncoming vehicle on a curve
When driving over a narrow iron bridge
When there is a metal object on the road surface
When driving on an uneven road surface (nose up, nose down)
When passing an oncoming vehicle on a left-turn (left-hand drive vehicles) or
right-turn (right-hand drive vehicles)
When your vehicle rapidly closes on the vehicle in front
When a grade separation/interchange, sign, billboard, or other structure appears
to be directly in the vehicle’s line of travel
When the steep angle of the road causes a metal object located beneath the road
surface to be seen ahead of the vehicle
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
When passing through certain toll gates
When passing through an overpass
When passing through a tunnel
When the system is activated in the situations described above, there is also a
possibility that the seat belts will retract quickly and the brakes will be applied
with a force greater than normal. When the seat belt is locked in the retracted
position, stop the vehicle in a safe place, release the seat belt and refasten it.
Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also
be occasions when the sensor cannot detect pedestrians, animals, bicycles,
motorcycles, trees, or snowdrifts.
Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of vehicle, such as at an intersection
If a vehicle suddenly cuts in front of vehicle, such as when overtaking
In inclement weather such as heavy rain, fog, snow or sand storms
When your vehicle is skidding with the VSC system off
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-crash safety system will be auto-
matically disabled. In this case, the system will not activate even if there is a col-
lision possibility.

When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
When water or snow thrown up by the surrounding vehicles hinders the func-
tioning of the sensor
When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
Vehicles that cut in suddenly
Vehicles with small rear ends (trailers with no load on board etc.)
Motorcycles traveling in the same lane
Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function effec-
tively:
Keep the sensor and front grille cover clean at all times.
Clean the sensor and front grille cover with a soft cloth so you do not mark or
damage them.
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become inaccu-
rate or malfunction. If the sensor or surrounding area is subject to a strong
impact, always have the area inspected and adjusted by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
Do not modify or paint the sensor and grille cover.
