When an obstacle is detected, the buzzer sounds.
●As the obstacle is approached, the buzzer sounds more rapidly.
When the obstacle is extremely cl ose, the buzzer switches from
sounding intermittently (short beeps) to continuously (a long beep). • Distance to obstacle detected by front corner sensor is approxi- mately 1.2 ft. (35 cm) or less
• Distance to obstacle detected by front side sensor or rear side
sensor is approximately 1.0 ft. (30 cm) or less
• Distance to obstacle detected by front sensor is approximately
1.2 ft. (35 cm) or less
• Distance to obstacle detected by rear corner sensor is approxi-
mately 1.2 ft. (35 cm) or less
• Distance to obstacle detected by back sensor is approximately
1.2 ft. (35 cm) or less
● When an obstacle is detected by multiple sensors simultaneously,
the buzzer sounds according to t he distance to the closest obsta-
cle.
● When obstacles are simultaneousl y detected to the front and rear
of the vehicle, separate buzzers sound patterns according to the
distance to each obstacle.
The volume and timing of the buzzer can be changed. ( P. 752)

• The detection range is shown in
the illustration to the right. How-
ever, the sensor will not detect
the obstacle if it is too close.

( P. 341)
• The distance at which an obsta- cle can be detected and whether
it can be detected depends on
the shape and condition of the
obstacle.
The obstacle detection range can be changed. ( P. 752)

■Operation conditions
The power switch is turned on.
●Front corner sensors:
• Shift position is not in P
• Vehicle speed is approximately 6 mph (10 km/h) or less
● Front side sensors/rear side sensors:
• Shift position is not in P
• Vehicle speed is approximately 6 mph (10 km/h) or less
• Steering wheel is turned approximately 90  or more
● Front center sensors:
• Shift position is not in P or R
• Vehicle speed is approximately 6 mph (10 km/h) or less
● Rear corner sensors/rear center sensors:
Shift position is in R

■ Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
● Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection 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
when traveling at a low speed, if you come too close to an obstacle before
the display and buzzer activate, the display and buzzer may not activate at
all.
● Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
● It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.

■Obstacle warning function
■ Obstacle detection in side areas
●Obstacles in the side areas are detec ted while driving by scanning the side
areas with the side sensors. Recognized obstacles are retained in memory
for up to approximately 2 minutes.
● Obstacles may not be detected in the side areas until the scan completes.
After the power switch is turned on, scanning completes after driving the
vehicle for a short period of time.
● When an obstacle such as another vehicle, pedestrian or animal is detected
by the side sensors, the obstacle may continue to be detected even after it
has left the side sensor detection area.
■ If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. 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 dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malf unction” is displayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: P. 752)
When an obstacle in the side areas is
within the vehicle course while the vehicle
is moving forward or backward, this func-
tion inform the driver by the display and
the buzzer.

WARNING
■When using Intuitive parking assist
Observe the following precautions to avoid an unexpected accident.
●Do not exceed the speed limit of 6 mph (10 km/h).
● The sensors’ detection areas and reaction 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.

WARNING
■Sensors
Certain vehicle conditions and the surrounding 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 problem.)
● 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.
● In harsh sunlight or intense cold weather
● 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 ultra-
sonic waves.
● The sensor is splashed with water or drenched with heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is leaning considerably to one side.
● The vehicle is equipped with a fender pole or wireless antenna.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● The area directly under the bumpers is not detected.
● If obstacles draw too close to the sensor.
● The bumper or sensor receives a strong impact.
● A non-genuine Toyota suspension (lowered suspension etc.) is installed.
● There is another vehicle equipped with parking assist sensors in the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate is installed.
In addition to the examples above, depending on the shape and condition of
obstacles, detection may not be possible, or the detection range may be
shortened.
