Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.

●

The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obstacle, the
buzzer sounds continuously.

• Front corner sensors: Approximately 1.0 ft. (30 cm)
• Front center sensors: Approximately 1.0 ft. (30 cm)
• Rear corner sensors: Approximately 0.8 ft. (25 cm)
• Rear center sensors: Approximately 1.3 ft. (40 cm)

Sensor detection information

●

The sensor’s detection areas are limited to the areas around the vehicle’s bumper.

●

Certain vehicle conditions and the surrounding environment may affect the ability of a

sensor to correctly detect an obstacle. Particular instances where this may occur are

listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this prob-

lem.)

• 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.

• 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.

256

4-5. Using the driving support systems

●

The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten-

tion 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 buzzer 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 audio system or air flow noise

of the air conditioning system.

CAUTION

■

When using the intuitive parking assist
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 6 mph (10 km/h).

●

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.

NOTICE

■

When using intuitive parking assist
In the following situations, the system may not function correctly due to a sensor mal-

function etc. Have the vehicle checked by your Lexus dealer.

●

A buzzer does not sound when you turn the intuitive parking assist on.

●

The intuitive parking assist operation display flashes, and a buzzer sounds when no

obstacles are detected.

●

If the area around a sensor collides with something, or is subjected to strong impact.

●

If the bumper collides with something.

●

If the display shows continuously without a beep.

●

If a display error occurs, first check the sensor.

If the error occurs even if 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.

plays an image of the view from the
bumper of the rear area of the vehi-
cle.
The image on the rear view monitor
system screen can be adjusted, refer
to the “MULTIMEDIA OWNER’S
MANUAL” or “NAVIGATION
SYSTEM OWNER’S MANUAL”.

• The area displayed on the screen

may vary according to vehicle orien-

tation conditions.

• Objects which are close to either

corner of the bumper or under the

bumper cannot be displayed.

• The camera uses a special lens. The

distance of the image that appears

on the screen differs from the actual

distance.

• Items which are located higher than the camera may not be displayed on the mon-

itor.

• If your vehicle is equipped with a backlit license plate, it may interfere with the dis-

play.

Rear view monitor system camera
The camera for the rear view moni-
tor system is located above the
license plate.

●

Using the camera
If dirt or foreign matter (such as water droplets, snow, mud etc.) is adhering
to the camera, it cannot transmit a clear image. In this case, flush it with a
large quantity of water and wipe the camera lens clean with a soft and wet
cloth.

■

Differences between the screen and the actual road
The distance guide lines and the vehicle width extension guide lines may not
actually be parallel with the dividing lines of the parking space, even when
they appear to be so. Be sure to check visually.
The distances between the vehicle width extension guide lines and the left and
right dividing lines of the parking space may not be equal, even when they
appear to be so. Be sure to check visually.
The distance guide lines give a distance guide for flat road surfaces. In any of
the following situations, there is a margin of error between the fixation guide
lines on the screen and the actual distance/course on the road.

●

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 fixation 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 outward (such as the flatbed of a truck),
be careful of the following.

●

Vehicle width extension guide lines
Visually check the surroundings
and the area behind the vehicle.
In the case shown in the illustra-
tion, the truck appears to be out-
side of the vehicle width
extension guide lines and the
vehicle does not look as if it hits
the truck. However, the rear body
of the truck may actually cross
over the vehicle width extension
guide lines. In reality if you back
up as guided by the vehicle width
extension guide lines, the vehicle
may hit the truck.
