WARNING
■Cautions regarding the use of the sys-
tem
There is a limit to the degree of recogni-
tion accuracy and control performance
that this system can provide, do not
overly rely on this system. The driver is
always responsible for paying attention
to the vehicle’ surroundings and driving
safely.
■To ensure the system can operate
properly
Observe the following precautions.
Failing to do so may result in the vehicle
being unable to be dr iven safely and pos-
sibly cause an accident.
●Do not damage the sensors, and
always keep them clean.
●Do not attach a sticker or install an
electronic compon ent, such as a
backlit license plate (especially fluo-
rescent type), fog lights, fender pole or
wireless antenna near a radar sensor.
●Do not subject the surrounding area of
the sensor to a strong impact. If sub-
jected to an impact, have the vehicle
inspected by your Lexus dealer. If the
front or rear bumper needs to be
emoved/installed or replaced, contact
your Lexus dealer.
●Do not modify, disassemble or paint
the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.

2404-5. Using the driving support systems
■The system can be operated when
●The engine switch is in IGNITION ON
mode.
●Intuitive parking assist function is on.
●The vehicle speed is less than about 6
mph (10 km/h).
●A shift lever other than P.
■Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. ( P.236)
■If “Parking Assist Unavailable” is dis-
played on the multi-information display
●Water may be continuo usly flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
●Initialization may not have been per-
formed after a battery terminal was dis-
connected and reconnec ted. Initialize the system. (
P.240) If this message contin-
ues to be displayed even after initializa-
tion, have the vehicle inspected by your
Lexus dealer.
■If “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-information display
A sensor may be covered with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warn ing message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal.
■If a battery terminal has been discon-
nected and reconnected
The system needs to be initialized. To initial-
ize the system, drive the vehicle straight
ahead for 5 seconds or more at a speed of
approximately 22 mph (35 km/h) or more.
■Sensor detection information
The following situations may occur during
use.
●The sensor's detection areas are limited
to the areas around the vehicle front and
rear bumpers.
●Depending on the sh ape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
●There will be a short delay between
object detection and di splay. Even at low
speeds, there is a possibility that the
object will come wi thin the sensor’s
detection areas befo re the display is
shown and the warning beep sounds.
●It might be difficult to hear the buzzer due
to the volume of the audio system or air
flow noise of the air conditioning system.
●It may be difficult to hear the buzzer if
buzzers for other systems are sounding.
■Objects which the system may not be
properly detected
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
WARNING
■When to disable the function
In the following situations, disable the
function as it may operate even though
there is no possibility of a collision.
●Failing to observe the warnings above.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is installed.
■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.
●When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●When using steam to clean the vehicle,
do not direct steam too close to the
sensors as doing so may cause a sen-
sor to malfunction.

ing outwards in the direction of your vehi-
cle
People may not be detected if they are
wearing certain types of clothing.
■Situations in which the system may not
operate properly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
●There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
●A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
●When a sensor or the area around a sen-
sor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●When vehicle horns, vehicle detectors,
motorcycle engines, air brakes of large
vehicles, the clearance sonar of other
vehicles or other devices which produce
ultrasonic waves are near the vehicle
●A sensor is coated with a sheet of spray
or heavy rain.
●If objects draw too close to the sensor.
●When a pedestrian is wearing clothing that does not reflect ultrasonic waves (ex.
skirts with gathers or frills).
●When objects that are not perpendicular
to the ground, not perpendicular to the
vehicle traveling direction, uneven, or
waving are in the detection range.
●Strong wind is blowing
●When driving in inclement weather such
as fog, snow or a sandstorm
●When an object that
cannot be detected
is between the vehicle and a detected
object
●If an object such as a vehicle, motorcycle,
bicycle or pedestrian cuts in front of the
vehicle or runs out from the side of the
vehicle
●If the orientation of a sensor has been
changed due to a collision or other
impact
●When equipment that may obstruct a
sensor is installed, such as a towing eye-
let, bumper protector (an additional trim
strip, etc.), bicycle carrier, or snow plow
●If the front of the vehicle is raised or low-
ered due to the carried load
●If the vehicle cannot be driven in a stable
manner, such as when the vehicle has
been in an accident or is malfunctioning
●When a tire chains, compact spare tire or
an emergency tire punc ture repair kit is
used
■Situations in which the system may
operate even if there is no possibility of a
collision

■Buzzer operation and distance to
an object
A buzzer sounds when the sensors are
operating.
 The buzzer beeps faster as the vehi-
cle approaches an object. When the
vehicle comes within the following
distance of the object, the buzzer
sounds continuously:
Approximately 1.0 ft. (30 cm)
When 2 or more objects are
detected simultaneously, the buzzer
sounds for the nearest object. If one
or more objects come within
approximately 1.0 ft. (30 cm) of the
vehicle, the buzzer 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.)
The buzzer sounds volume can be
adjusted. ( P.236)
