■Intuitive parking assist display
When an obstacle is detected while the rear view monitor system, is in use, the warn-
ing indicator will appear in the top right of the screen even if the display setting has
been set to off.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s front cor-
ner and rear bumpers.
●Certain vehicle conditions and the surrounding environment may affect the ability
of the sensor to correctly detect obstacles. Particular instances where this may
occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the screen may show an abnor-
mal display, or obstacle s may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under th e bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their
shape, signs and other objects may be judged by the se nsor to be closer than they
are.

●The shape of the obstacle may prevent the sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi als that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obst acle detection and display. Even at slow
speeds, there is a possibility that the obstacle will come within the sensor’s
detection areas before the display is shown and the warning beep sounds.
• Thin posts or objects lower than the se nsor may not be detected for collision
when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow noise of air conditioning system.

CAUTION
■When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and possi-
bly cause an accident.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
●The sensors’ detection areas and reaction times are limited. When moving for-
ward or reversing, check the areas surrounding the vehicle (especially the sides
of the vehicle) for safety, and drive slowly, using the brake to control the vehicle’s
speed.
●Do not install accessories within the sensors’ detection areas.
NOTICE
■When using intuitive parking assist-sensor
In the following situations, the system may not function correctly due to a sensor
malfunction etc. Have the vehicl e checked by your Lexus dealer.
●The intuitive parking assist operation disp lay flashes, and a beep sounds when no
obstacles are detected.
●If the area around a sensor collides with something, or is subjected to strong
impact.
●If the bumper collides with something.
●If the display shows continuously without a beep.
●If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is likely that
the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of wa ter or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

PCS (Pre-Collision System)
◆Pre-collision seat belts (front seat only)
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the dr iver makes an emergency braking or
loses control of the vehicle. ( P. 32)
◆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 poss ibility of a frontal collision, the system warns
the driver using a warning light, war ning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed.

: If equipped
When the radar sensor detects that a frontal collision is highly likely or
even unavoidable, safety systems such as the brakes and seat belts are
automatically engaged to lessen impact as well as vehicle damage.
The pre-collision system ca n be turned on and off as necessary by oper-
ating the switch. ( P. 280)

Enabled
Disabled
The “PCS” warning light comes on
when pre-collision system is disabled.
The radar sensor detects vehicles or
other obstacles on or near the road
ahead and determines whether a
collision is imminent based on the
position, speed, and heading of the
obstacles.
The driver monitor sensor detects
the direction the driver is facing and
whether the driver’s eyes are open
or closed.
The system determines whether the
driver is facing forward and whether
or not the driver’s eyes are closed.

■Conditions that may trigger the system even if there is no danger 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
●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 climbing a steep hill causes an overhead billboard or other metallic structure
to appear directly in the vehicle’s line of travel
When the system is activated in the situations described above, there is also a possi-
bility 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, motorcy-
cles, 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 your vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●When your vehicle is skidding such as the VSC system off
●When your vehicle is steeply inclined

■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the sen-
sors being unable to detect obstacles, the pre-collision system will be automatically
disabled. In this case, the system will not activate even if there is a collision possibility.
■When there is a malfunction in the system
“PCS” warning light will flash and warning messages will be displayed.
