Lexus ES350 Service Manual page 227

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 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 detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle 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 sensor 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.
If "Clean Parking Assist Sensor" is displayed 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 not be detected. If
the sensor thaws out, the system should return to normal.
If "Parking Assist Malfunction" is displayed 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.

cause an accident, resulting in death or serious injury.
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
