surrounding vehicles hinders the detect-
ing of the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage

■Conditions under which the vehicle-to-
vehicle distance control mode may not
function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as nec-
essary.

ates suddenly
●When driving on a road surrounded by a
structure, such as in a tunnel or on a

the set speed after the vehicle acceler-
ates by depressing the accelerator pedal

*2: The greater the difference in speed between your vehicle and the detected vehicle is, the farther away the vehicle will be detected, causing the outside rear view mirror indi-
cator to illuminate or flash.
■The Blind Spot Monitor is operational
when
The Blind Spot Monitor is operational when
all of the following conditions are met:
●The Blind Spot Monitor is on.
●The shift lever is in a position other than R.
●The vehicle speed is greater than approx-
imately 10 mph (16 km/h).

present in the detection area in the follow-
ing situations:
●A vehicle in an adj acent lane overtakes
your vehicle.
●You overtake a vehicle in adjacent lane
slowly.
●Another vehicle enters the detection
area when it changes lanes.
■Conditions under wh ich the Blind Spot
Monitor will not detect a vehicle
The Blind Spot Monitor is not designed to
detect the following types of vehicles and/or
objects:
●Small motorcycles, bicycles, pedestrians,
etc.*
●Vehicles traveling in the opposite direc-
tion
●Guardrails, walls, signs, parked vehicles
and similar stationary objects*
●Following vehicles th at are in the same
lane*
●Vehicles traveling 2 lanes away from your
vehicle*
●Vehicles which are being overtaken rap-
idly by your vehicle*
*
: Depending on the conditions, detection of a vehicle and/or object may occur.
■Conditions under which the Blind Spot
Monitor may not function correctly
●The Blind Spot Monitor may not detect
vehicles correctly in the following situa-
tions:

strong impact to the sensor or its sur-
rounding area

covering the sensor or surrounding area
on the rear bumper
• When driving on a road surface that is
wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching
with only a small gap between each vehi-
cle
• When the distance between your vehicle
and a following vehicle is short
• When there is a significant difference in speed between your vehicle and the vehi-
cle that enters the detection area
• When the difference in speed between your vehicle and another vehicle is
changing
• When a vehicle enters a detection area traveling at about the same speed as your
vehicle
• As your vehicle starts from a stop, a vehi- cle remains in the detection area
• When driving up and down consecutive steep inclines, such as hills, dips in the
road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When vehicle lanes are wide, or when
driving on the edge of a lane, and the
vehicle in an adjacent lane is far away
from your vehicle

cle
• When there is a significant difference in
height between your vehicle and the
vehicle that enters the detection area

unnecessarily detecting a vehicle and/or

2224-5. Using the driving support systems
■The system can be operated when
●The engine switch is in ON.
●Intuitive parking assist function is on.
●The vehicle speed is less than about 6
mph (10 km/h).
●The shift lever is in a position other than P.
■Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. ( P.219)
■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 warning 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.
■Sensor detection information
●The sensor’s detectio n areas are limited
to the areas around the vehicle’s front and
rear bumpers.
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.
●The area directly under the bumpers is
not detected.
■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.
●The vehicle is equipped with a fender
pole or wireless antenna.
●The front or rear bu mper or a sensor
receives a strong impact.
●A non-genuine Lexus suspension
(lowered suspension, etc.) is installed.
●Towing eyelet is installed.
●A backlit license plate is installed.
■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 or shows continuously,
and a beep sounds when no objects
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 flashes or is displayed
continuously and a buzzer does not
sound, except when the mute function
has been turned on.
●If a display error oc curs, 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 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.
