Detects vehicles or other obsta-
cles on or near the road ahead
and determines whether a colli-
sion is imminent based on the
position, speed, and heading of
the obstacles.

Obstacles not detected
The sensor cannot detect plastic obstacles such as pylons. There may also be
occasions when the radar sensor cannot detect pedestrians, animals, bicy-
cles, motorcycles, trees, or snowdrifts.
The pre-crash safety system is operational when
Pre-crash seat belts (type A):
• Vehicle speed is above 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or oncom-
ing vehicle exceeds 30 km/h (19 mph).
• The front occupants are wearing a seat belt.
Pre-crash seat belts (type B):
• Vehicle speed exceeds 30 km/h (19 mph).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
Pre-crash brake assist
• Vehicle speed is above 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than 30 to 40 km/h (19 to 25
mph).
• The brake pedal is depressed.
Pre-crash braking
• The pre-crash braking function is activated.
• Vehicle speed is above 15 km/h (10 mph).
• The relative speed difference between your vehicle and another vehi-
cle that is forward of your vehicle, or the speed at which your vehicle
is approaching an obstacle is greater than 15 km/h (10 mph).
Conditions that may trigger the system even if there is no possibility of col-
lision
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

When passing an oncoming vehicle on a right-turn (right-hand drive
countries) or left-turn (left-hand drive countries)
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 an overhead billboard or other metallic structure appears to be in
the vehicle’s direct line of travel due to driving on a hill.
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 driving on a bridge.
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.
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 425,
431)
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 your vehicle, such as at an inter-
section
If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
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 automatically disabled. In this case, the system will not activate even if
there is a collision possibility.

CAUTION
Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function
effectively.
Keep the sensor and front grille clean at all times.
Clean the sensor and front grille 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
inaccurate or malfunction. If the sensor or surrounding area are 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 guard or sur-
rounding area.
Do not modify or paint the sensor and grille.
Limitations of the pre-crash safety system
Do not rely on the pre-crash safety system. Always drive safely, taking care
to observe your surroundings and checking for any obstacles or other road
hazards.
Failure to do so may cause an accident resulting in death or serious injury.
