PCS (Pre-Collision System)∗
◆Pre-collision seat belts (front seat belts only)
If the pre-collision sensor detects that a collision is unavoidable, the pre-colli-
sion system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. (
→P. 3 3 )
However, when the VSC system is disabled, the system will not operate in the
event of skidding.
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is depressed.
◆Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning display and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-collision braking can be disabled using the
pre-collision braking off switch.
Pre-collision braking disabled
Pre-collision braking enabled
The “PCS” warning light will turn on
when pre-collision braking is dis-
abled.
∗: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-colli-
sion system such as the brakes and seat belts are automatically engaged to
lessen impact as well as vehicle damage.

Driving
The radar sensor detects vehicles or
other obstacles on or near the road
ahead and determines whether a colli-
sion is imminent based on the position,
speed, and heading of the obstacles.
■The pre-collision system is operational when
●Pre-collision seat belts (type A)
• Vehicle speed is greater than about 19 mph (30 km/h).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
●Pre-collision seat belts (type B)
• Vehicle speed is greater than about 4 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 19 mph (30 km/h).
• The front occupants are wearing a seat belt.
●Pre-collision brake assist:
• Vehicle speed is greater than about 19 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The brake pedal is depressed.
●Pre-collision braking:
• The pre-collision braking off switch is not pressed.
• Vehicle speed is greater than about 10 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 10 mph (15 km/h).

■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
●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 sur-
face 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 occa-
sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees,
or snowdrifts.
■Situations in which the pre-collision 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-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-collision system will be automatically disabled.
In this case, the system will not activat e even if there is a collision possibility.
■When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights and/or warning messages will turn on or flash. ( →P. 5 2 7 , 5 3 4 )

■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pr
e-collision system is intended to assist the
driver in avoiding collisions through the process of LOOK-JUDGE-ACT. There are
limits to the degree of assistance the system can provide, so please keep in mind the
following important points.
●Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of the vehicle,
and only within a limited range. It is not a mechanism that allows careless or inatten-
tive driving, and it is not a system that can as sist the driver in low-visibility conditions. It
is still necessary for the driver to pay close attention to the vehicle’s surroundings.
●Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data available to
the pre-collision system is that from obstacles it has detected directly in front of the
vehicle. Therefore, it is absolutely necessary for the driver to remain vigilant and to
determine whether or not there is a possibility of collision in any given situation.
●Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help reduce the sever-
ity of a collision, and so on ly acts when the system has judged that a collision is
unavoidable. This system by itself is not capable of automatically avoiding a collision
or bringing the vehicle to a stop safely. For this reason, when encountering a danger-
ous situation the driver must take direct and immediate action in order to ensure the
safety of all involved.
■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 functioning
of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage com-
partment 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-collision system can function effectively:
●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 dam-
age 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 is subject to a strong impact, always
have the area inspected and adjusted by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to th e sensor, grille cover or surrounding area.
●Do not modify or paint the sensor and grille cover.
