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 possibly
cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●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.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and surrounding environments, such as the following, may
affect the ability of the sensors to correctly detect objects. Pay particular attention in
the following situations. Failure to do so may result in the vehicle being driven
unsafely, possibly leading to an accident.
• 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 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 lo ud 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 (lowered 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.
