Driving
• When the Lexus parking assist-sensor is turned off once and turned on again• When the engine switch
is turned off once and turned to IGNI- TION ON mode again
■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 “Park-ing 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 any autho- rized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Sensor detection 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 fro-
zen the screen may show an abnormal dis-
play, 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 grav el, 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 splashed with water 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
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 before the display is shown and the warning beep sounds.

4-5. Using the driving support systems
• Thin posts or objects 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.
■Customization
Some functions can be customized. ( P.423)
■Detection range of the sensors
Approximately 100 cm (3.3 ft.)
WARNING
■When using the Lexus parking assist- sensor
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and pos-sibly cause an accident.
●Do not use the sensor at speeds in
excess of 10 km/h (6 mph).
●The sensors’ detection areas and reac- tion times are limited. When moving forward 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 Lexus parking assist-sen-sor
In the following situations, the system may not function correctly due to a sen-
sor malfunction etc. Have the vehicle checked by any authorized Lexus retailer or Lexus authorized repairer, or any reli-
able repairer.
●The Lexus parking assist-sensor oper- ation display flashes or shows continu-
ously, 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 or grille collides with something.
●If the display flashes or shows continu-ously without beeping, except when
the mute function has been turned on.
●If a display error occurs, first check the sensor. If the error occurs even when there is
no ice, snow or mud on the sensor, it is likely that the sensor is malfunctioning.
