■Sensor detectio n information
●The sensor’s detection areas are limited
to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the sur-
rounding 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
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.
• A backlit license plate, license plate holder, etc., are installed.
• 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 a
sensor to be closer than they are.
●The shape of the obstacle may prevent a
sensor from detecting it. Pay particular
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 buzzer 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 audio system or air flow
noise of the air conditioning system.
■Customization
Some functions can be customized.
(Customizable features: P.441)
WARNING
■When using the intuitive parking
assist
Observe the following precautions.
Failure 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 6 mph (10 km/h).

■Detection range of the sensorsApproximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 1.9 ft. (65 cm)
The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect obstacles that are extremely close
to the vehicle.
The range of the sensors may change
depending on the shape of the object etc.
■Distance display
Sensors that detect an obstacle will illu-
minate continuously or blink. (As the
distance to the object becomes less
than 1.0 ft. (30 cm), the distance seg-
ments may blink.)
WARNING
●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 intuitive parking assist
In the following situations, the system
may not function correctly due to a sen-
sor malfunction, etc. Have the vehicle
checked by your Lexus dealer.
●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 with-
out 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 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 mal-
functioning.

■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 approximately 1.0 ft. (30 cm) of the
obstacle, the buzze
r sounds contin-
uously.
 When 2 or more obstacles are
detected simultaneously, the buzzer
system responds to the nearest
obstacle. If one or both come within
the above distances, the beep will
repeat a long tone, followed by fast
beeps.
 Automatic buzzer mute function:
After a buzzer begins sounding, if
the distance between the vehicle
and the detected object does not
become shorter, the buzzer will be
muted automatically. (However, if
the distance between the vehicle
and object is 1.0 ft. (30 cm) or less,
this function will not operate.)

*:If equipped
The system operates in the following
situations when a static object is
detected in the traveling direction of
the vehicle.
■The vehicle is driven at low speeds
and the brake pedal is not
depressed, or is depressed too late
■The accelerator pedal is depressed
too far
Parking Support Brake func-
tion (for static objects)*
When a collision may occur with a
static object while parking or trav-
eling at low speeds, when the vehi-
cle suddenly moves forward due to
mistaken accelerator pedal opera-
tion, or when the vehicle moves due
to the shift lever being in the wrong
position, the sensors detect static
objects to the front or rear in the
traveling direction of the vehicle,
and the system operates to lessen
impact with static objects such as
walls, and reduce resulting dam-
age.

WARNING
■For safe use
Do not rely solely upon the system. Rely-
ing solely upon the sy stem may lead to an
unexpected accident.
●Driving safely is the sole responsibility
of the driver. Pay careful attention to
the surrounding conditions in order to
ensure safe driving. The Parking Sup-
port Brake function (f or static objects)
can provide support to lessen the
severity of collisions. However, it may
not operate depending on the situa-
tion.
●The Parking Support Brake function
(for static objects) is not a system
designed to completely stop the vehi-
cle. Furthermore, even if the Parking
Support Brake function (for static
objects) is able to stop the vehicle,
brake control is canceled after
approximately 2 seco nds, so depress
the brake pedal immediately.

to an impact, equipment may not oper-
ate properly due to a sensor malfunc-
tion. Have the vehicle inspected by
your Lexus dealer.
●When using a high-pressure washer to
wash the vehicle, do not spray water
directly on the sensors. The sensors
may not function properly if subjected
to an impact from strong water pres-
sure.
