■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal
when deceleration of the system is insufficient or operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the approach
warning (
→P. 233) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane
●Vehicles with small rear ends (trailers with no load on board, etc.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the surrounding vehicles hinders the detecting of
the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage com-
partment, etc.)
●Preceding vehicle has an extremely high
ground clearance

■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 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 indicat
or 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 screen 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 distance of the obstacle, the buzzer
sounds continuously:• Front center sensors: Approximately 1.0 ft. (30 cm)
• Corner sensors: Approximately 1.0 ft. (30 cm)
• Rear center sensors: Approximately 1.1 ft. (35 cm)
●When 2 or more obstacles are detected simultaneously, the buzzer system
responds to the nearest obstacle. If on e or both come within the above dis-
tances, the beep will repeat a long 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 the 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 detected 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 detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s front corners
and rear bumper.
●Certain vehicle conditions and the surrou nding 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 th e 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 co nsiderably 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 receives 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 (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their shape,
signs and other objects may be judged by the sensor to be closer than they are.
