2064-5. Using the driving support systems
■If “Clean Parking Assist Sensor” is dis-
played 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 nor-
mal.
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” or
“Parking Assist Malfunction Visit Your
Dealer” is displayed on the multi-infor-
mation display
There is a malfunction and the device may
not be working properly.
Have the vehicle inspected by your Lexus
dealer.
■Sensor detectio n information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front
and rear bumpers.
●Certain vehicle conditions and the sur-
rounding 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 abnormal
display, or obstacles 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 sensor 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, be cause of their shape,
signs and other objects may be judged by
the sensor to be closer than they are.
●The shape of the obstacle may prevent
the sensor from detecting it. Pay particu-
lar 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 pro- jecting 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 distance
may shorten, or detection may be impos-
sible.
• 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 befo re the display is
shown and the warning beep sounds.
• Thin posts or object s lower than the sen-
sor may not be detected when
approached, even if they have been
detected once.
• It might be difficult to hear beeps due to the volume of the audio system or air flow
noise of the air conditioning system.
• It might be difficult to hear beeps due to the sounds of other systems.
