■PCS-linked Pop Up Hood operation 
control
If the PCS (Pre-Collision System) deter-
mines that the possibility of a collision with a 
pedestrian or bicyclist is high, the Pop Up 
Hood will be prepared to operate.
■Pop Up Hood operational conditions
The Pop Up Hood will operate when the 
vehicle detects an impact such as the fol-
lowing:
●The front bumper detects a frontal impact 
equivalent to or grea ter than that of a 
pedestrian while the vehicle being driven 
within the operational speed range of 
approximately 16 to 34 mph (25 to 55 
km/h). (The system is operated by an 
impact of threshold le vel or greater, even 
in the case of a minor collision that may 
not leave a trace on the front bumper. 
Also, depending on the impact condi-
tions or vehicle speed, the system may 
operate by a collision with a light or small 
object or a small animal.)
●In other situations, such as the following 
the system may operate when an impact 
is applied to the lowe r part of the vehicle 
or front bumper:
• Colliding with a curb
• Falling into a deep hole
• Landing hard
• Hitting the slope of a parking lot, an  undulating road, a protruding object or 
falling object
■Conditions under which the Pop Up 
Hood may not operate properly
●If a pedestrian collides with the right or 
left corner of the front bumper or the side 
of the vehicle. As  such impacts may be 
difficult to detect, the system may not 
operate.
●If the vehicle speed is not detected cor-
rectly, such as if the vehicle is sliding side-
ways, the system may not operate 
properly.
■Conditions under which the Pop Up 
Hood will not operate
The Pop Up Hood will not operate in the 
following situations:
●Colliding with a lying person
●A frontal impact applied to the front 
bumper while driving at speeds outside 
of the operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident situ-
ations, the Pop Up Hood may operate.)
WARNING
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever. 
Doing so after the Pop Up Hood has 
operated will further raise the hood 
and may cause an injury. Do not drive 
with the hood raised, as doing so may 
block the driver’s vision, possibly caus-
ing an accident.
●Do not forcibly push down the hood. 
As the popped up hood cannot be 
lowered by hand, doing so may deform 
the hood or cause an injury.
●If the Pop Up Hood has operated, have 
it replaced by your Lexus dealer. If the 
Pop Up Hood has operated, stop the 
vehicle in a safe place and contact 
your Lexus dealer.
●Do not touch the lifters immediately 
after the Pop Up Hood has operated, 
as the lifters may be hot and burn you.
NOTICE
■Pop Up Hood precautions
●Make sure to close the hood before 
driving, as the system may not operate 
properly if the hood is not fully closed.
●Make sure that all 4 tires are of the 
specified size and inflated to the speci-
fied tire pressure. If  tires of a different 
size are used, the system may not 
operate properly.
●If something has hit the area around 
the front bumper, the sensors may be 
damaged even if the Pop Up Hood has 
not operated. Have the vehicle 
inspected by your Lexus dealer.

WARNING
■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 pos-
sibly cause an accident.
●Do not use the sensor at speeds in 
excess of 6 mph (10 km/h).
●The sensors’ detection areas and reac-
tion times are limited. When moving 
forward or reversin g, 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. Thin posts or objects 
lower than the sensor may not be 
detected when approached, even if 
they have been detected once.
■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, wireless antenna or fog lights.
●The front or rear bumper or a sensor 
receives a strong impact.
●A non-genuine Lexus suspension 
(lowered suspension, etc.) is installed.
●Towing eyelets are installed.
●A backlit licence pl ate is installed.

■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 position other than P is selected.
■Setting the buzzer volume
The buzzer volume can be adjusted on the 
multi-information display. ( P.258)
■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.
■If “Parking Assist Unavailable” is dis-
played on the multi-information display
●Water may be continuously 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 reconnected. Initialize the 
system. ( P.261)
If this message continues to be displayed 
even after initializati on, have the vehicle 
inspected by your Lexus dealer.
■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. 
Additionally, for vehicles with the Parking 
Support Brake function, turn the steering 
wheel fully to the left and right with the vehi-
cle stopped.
■Sensor detection information
●The following situations may occur 
during use.
• The sensors may be able to only detect  objects near the fron t and rear bumpers.
• Depending on the shape of the object  and other factors, the detection distance 
WARNING
■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 buzzer 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 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 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. 

2624-5. Using the driving support systems
may shorten, or detection may be impos-
sible.
• There will be a short delay between 
object detection and display. Even at low 
speeds, there is a possibility that the 
object will come within the sensor’s 
detection areas before 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.
■Conditions under which the function 
may not function correctly
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.
●A sensor is covered in any way.
●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.
●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.
●A sensor is coated with a sheet of spray 
or heavy rain.
●If a sensor is hit by a large amount of 
water, such as when driving on a flooded 
road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall or 
curved curb.
●If objects draw too close to the sensor.
■Objects which may not be properly 
detected
The shape of the object may prevent the 
sensor from detectin g it. Pay particular 
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that 
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections project-
ing outwards in the direction of your vehi-
cle
People may not be de tected if they are 
wearing certain types of clothing.
