Sensor detectio n information●
The sensor’s detection areas are limited to the areas around the vehicle’s bumper. ●
Certain vehicle conditions and the surround ing environment may affect the ability of a
sensor to correctly detect an obstacle. Particular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing th e area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning co nsiderably 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 the 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 a sensor to be closer than they are.●
The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten-
tion to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle ●
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion 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 w ill come within the sensor’s detection
areas before the display is shown and the buzzer sounds.
• Thin posts or objects lower than the sensor may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to th e volume of audio system or air flow noise
of the air conditioning system.

If “Clean Parking Assist Sensor” is di splayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from the
sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may
appear or an obstacle may no t be detected. If the sensor thaws out, the system should
return to normal. ■
If “Parking Assist Malfunction” is di splayed on the multi-information display
Depending on the malfunction of the sensor, the device may not be working normally.
Have the vehicle inspected by your Lexus dealer. ■

WA R N I N G ■
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 possibly
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 forward or
reversing, check the areas surrounding the vehicle (especially the sides of the vehi-
cle) 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
In the following situations, the system may not function correctly due to a sensor mal-
function, etc. Have the vehicle checked by your Lexus dealer. ●
The intuitive parking assist operation display flashes, and a buzzer sounds when no
obstacles are detected. ●
If the area around a sensor collides with so mething, or is subjec ted to strong impact.●
If the bumper collides with something. ●
If the display shows continuously withou t beeping, except when the buzzer mute
switch has been turned on. ●
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 water or steam to the sensor area.
Doing so may result in th e sensor malfunctioning.
