Sensor detection information
The sensor’s detection areas are limited to the areas around the vehicle’s front
corner and rear bumpers.
Certain vehicle conditions and the surrounding 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 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 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 projecting 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 dis-
tance 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 sen-
sor’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 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.

CAUTION
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 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-sensor
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 dealer
or repairer, or another duly qualified and equipped professional.
The Lexus parking assist-sensor operation display flashes, 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 shows continuously without 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 when 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 the sensor malfunctioning.

When any part of the vehicle sags
When any part of the vehicle sags
due to the number of passengers
or the distribution of the load,
there is a margin of error between
the fixed guide lines on the
screen and the actual distance/
course on the road.
When approaching three-dimensional objects
The distance guide lines are displayed according to flat surfaced
objects (such as the road). It is not possible to determine the position of
three-dimensional objects (such as vehicles) using the distance guide
lines. When approaching a three-dimensional object that extends out-
ward (such as the flatbed of a truck), be careful of the following.
Distance guidelines
Visually check the surroundings
and the area behind the vehicle.

from the actual state.
Use caution, just as you would when backing up any vehicle.
Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic
conditions, road surface conditions, vehicle condition, etc. when parking. It is
necessary to be fully aware of this before using the rear view monitor system.
When parking, be sure to check that the parking space will accommodate your
vehicle before maneuvering into it.
Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains
• When the trunk lid is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
In low temperatures, the screen may darken or the image may become faint.
The image could distort when the vehicle is moving, or you may become
unable to see the image on the screen. Be sure to check direct visually and
with the mirrors all around the vehicle before proceeding.
If the tire sizes are changed, the position of the fixed guide lines displayed on
the screen may change.
The camera uses a special lens. The distances between objects and pedestrians
that appear in the image displayed on the screen will differ from the actual
distances.
