■Conditions under which the ve
hicle-to-vehicle distance control mode may not function
correctly
In the case of the following conditions, o perate the brake pedal (or accelerator pedal,
depending on the situ ation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system may not
operate properly.
●When the vehicle ahead of you decelerates suddenly
●When the road curves or when the lanes are
narrow
●When steering wheel operation or your posi-
tion in the lane is unstable

Intuitive parking assist∗
∗: If equipped
The distance from your vehicle to nearby obstacles when parallel parking or
maneuvering into a garage is measured
by the sensors and communicated via
the multi-information display, navigation system screen or Lexus Display
Audio system screen and a buzzer. Always check the surrounding area when
using this system.

Turns the intuitive parking assist on/off
When on, the indicator light comes on
to inform the driver that the system is
operational.
When the sensors detect an obstacle, a
graphic is shown on the multi-informa-
tion display and navigation system scre en or Lexus Display Audio system screen
depending on the position and distance to the obstacle.

■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer beeps faster as the vehicle approaches an obstacle. When the
vehicle comes within the following di stance of the obstacle, the buzzer
sounds continuously: • Front center sensors: Ap proximately 1.0 ft. (30 cm)
• Corner sensors: Approximately 1.0 ft. (30 cm)
• Rear center sensors: Appr oximately 1.1 ft. (35 cm)
●When 2 or more obstacles are detected simultaneously, the buzzer system
responds to the nearest obstacle. If one or both come within the above dis-
tances, the beep will repeat a lo ng tone, followed by fast beeps.
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows th e 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.

■The intuitive parking assist can be operated when
●Front center sensors:
• The power switch is in ON mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Front corner sensors:
• The power switch is in ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than about 6 mph (10 km/h).(At any speed when the shift lever is in R)
●Rear corner and rear center sensors:
• The power switch is in ON mode.
• The shift lever is in R.
■Intuitive parking assist display
When an obstacle is de tected while the Lexus parking assist monitor is in use, the warn-
ing indicator will appear in the upper part of the screen even if the display setting has
been set to off.
■Sensor detectio n information
●The sensor’s detection areas ar e limited to the areas around the vehicle’s front corners
and rear bumper.
●Certain vehicle conditions and the surroundi ng environment may affect the ability of
the sensor to correctly detect obstacles. Particular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.)
• 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 re ceives a strong impact.
• 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 ar e instances in which, because of their shape,
signs and other objects may be judged by the sensor to be closer than they are.

ES300h_OM_OM33D45U_(U)4-5. Using the driving support systems
●The shape of the obstacle may prevent the
sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi als that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion may be impossible.
• 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 th at the obstacle will come within the sensor’s detection
areas before the display is shown and the warning beep sounds.
• Thin posts or objects lower than the sens or may not be detected for collision when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to th e volume of audio system or air flow noise
of air conditioning system.
■If “Clean Parking Assist Sensor” is di splayed on the multi-information display
A sensor may be dirty or covered with snow or ic e. In such cases, if it is removed from the
sensor, the system should return to normal. Also, due to the sensor being frozen at low
temperatures, a malfunction display may appear or an obstacle may not be detected. If
the sensor thaws out, the syst em should return to normal.
■If “Parking Assist Malfunction” is di splayed on the multi-information display
Depending on the malfunction of the sensor, the device may not be working normally.
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 be ing unable to be driven safely and possibly
cause an accident, resulting in death or serious injury.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
●The sensors’ detection areas and reaction ti mes are limited. When moving forward or
reversing, check the areas surrounding the vehicle (especially the sides of the vehi-
cle) for safety, and drive slowly, using the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
