Steering guide symbol
Displays the steering maneuvers required to avoid an obstacle. Move the
steering wheel in the direction shown by the arrow.
The steering guide symbol only
shows the maneuvers necessary to
avoid an obstacle.
When using the system, always
check your surroundings for
safety.
Beeps and obstacle distance
A beep sounds when an obstacle with which there is a danger of collision
is detected. As the vehicle moves closer to the obstacle, the interval of
the beep becomes shorter.
●When the following obstacle distances are reached, the beep changes
from intermittent to continuous:
• If the distance to the obstacle detected by the dual sensors or rear corner
sensors is less than 0.8 ft. (25 cm).
• If the distance to the obstacle detected by the back sensors is less than 1.1
ft. (35 cm).
●If obstacles are detected by the dual sensors in 2 places at once, or if
both rear corner sensors detect obstacles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.

●If multiple obstacles are detected in front and behind the vehicle at the
same time, the warning beep will change in the following manner:
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected near a different area of the vehicle, the warning beep will sound
6 beeps then one continuous beep.
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected within 0.8 ft. (25 cm) of a different area of the vehicle, the warn-
ing beeps will sound 2 beeps then one continuous beep.
●You can change the volume of the warning beeps. (P. 2 5 8 )
Obstacle detection range
About 10.0 ft. (300 cm)
About 3.0 ft. (100 cm)
About 5.0 ft. (150 cm)
About 1.5 ft. (50 cm)
The detection area of the sensors is
shown to the left.
If obstacles move too close to the
sensors, they will not be detected.
If the malfunction screen is dis-
played, the dual sensor detection
range will be shortened from 3.0 ft.
(100 cm) to 1.5 ft. (50 cm).

■The intuitive parking assist can be operated when
The “POWER” switch is in the ON mode.
■When the system malfunctions
●If a malfunction occurs and no obstacles have been detected, a warning is dis-
played, and a malfunction beep sounds for 7 seconds.
If an obstacle has been detected, or another malfunction occurs in a different
sensor, the malfunction beeps will not sound.
●In the following circumstances the displayed warning will disappear:
• If you switch the screen to a different mode.
• If you turn off the intuitive parking assist main switch.
• If the vehicle speed exceeds 6 mph (10 km/h). Once the vehicle speed drops
below 6 mph (10 km/h), the warning will be displayed again.
●If the malfunction screen is displayed, the detection range of the dual sensors is
shortened. In this case, the necessity for obstacle evasion (whether the obstacle
will come within 0.8 ft. [25 cm] of the vehicle or not) will not be calculated.
■When using the intuitive parking assist
●The sensors’ detection areas and reaction times are limited. When moving for-
ward 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.
• The sensors’ detection areas are limited to the areas around the vehicle’s front
and rear bumpers.
• Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.
• 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 0.8 ft. (25
cm) of the vehicle before the display is shown and the warning beep sounds.
• Braking distance may differ according to the road conditions (rain, gravel
etc.).
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of air conditioning system.
• For long obstacles such as walls, the obstacle warning may change as the
obstacle gets closer.

●In the following situations, the intuitive parking assist may not function correctly,
possibly leading to an accident.
• There is ice, snow or mud on the sensors. (Wiping the sensors will resolve this
problem.)
• The sensor area is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnor-
mal display, or obstacles may not be detected.
• The vehicle angle is especially wide.
• In harsh sunlight or intense cold weather.
• When driving on bumpy, sloped or gravel roads, or over grass.
• If there is something producing ultrasonic waves nearby, such as another
vehicle’s horn, motorcycle engine noise, air braking sound from heavy-duty
vehicles, or another vehicle using the intuitive parking assist.
• In heavy rain, or if water is splashed on the sensors.
• If a commercial fender pole or radio antenna is installed.
• If towing eyelet is installed on your vehicle.
• If moving towards a high curb or a curb corner.
• Objects such as signs may cause the detection distance to shorten.
• The area directly under the bumpers is not detected.
Objects lower than the sensors or thin stakes etc. may be detected initially,
but as they draw closer, they may cease to be detected.
• If obstacles draw too close to the sensor.
■Obstacles that may not be detected correctly
The following obstacles may not be detected.
●Thin objects such as wire, fencing or rope.
●Objects that absorb sound waves, such as cotton or snow.
●Objects with sharp corners.
●Objects where the upper section projects out over the lower section.
●Low objects.

CAUTION
■While driving
To reduce the chance of injury in the event of an accident or sudden stop, keep the
switch box closed.
■When using the intuitive parking assist
Observe the following precautions.
●The back sensors and rear corner sensors do not judge whether there is danger
of a collision, nor whether the obstacle can be avoided using the steering wheel.
When reversing, always check your surroundings and behind the vehicle for
safety.
●The steering guide symbol (arrow) is an approximate guide regarding obstacles.
It is not driving instructions. When moving forward or reversing, always check
your surroundings for safety and drive carefully.
●Do not install accessories within the sensors’ detection areas, as this may cause
the intuitive parking assist to function incorrectly, possibly leading to an accident.

NOTICE
■When using the intuitive parking assist
In the following situations, the system may not function correctly due to a sensor
malfunction etc. Have the vehicle checked by your Lexus dealer.
●A beep does not sound when you turn the main switch on.
●The intuitive parking assist operation display flashes, and a beep sound when no
obstacle has been 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.
■When changing tires
If you install tires of a size other than that recommended by the manufacturer, the
system will be unable to correctly detect steering wheel movement. Always use tire
sizes recommended by the manufacturer.
■When washing the vehicle
When washing the vehicle using high pressure cleaning equipment, do not spray
water directly on the sensors. Subjecting the sensors to high pressure impact may
cause a malfunction.
