■The Toyota parking assist-sensor can be operated when
Vehicles without a smart entry & start system:
The engine switch is in the “ON” position.
Vehicles with a smart entry & start system:
The engine switch is in IGNITION ON mode.
● Front corner sensors/front center sensors:
• Vehicles with a Multidrive: The shift lever is in a position other than P.
• Vehicle speed is approximately 10 km/h (6 mph) or less
● Front side sensors/rear side sensors:
• Vehicles with a Multidrive: The shift lever is in a position other than P.
• Vehicle speed is approximately 10 km/h (6 mph) or less
• Steering wheel is turned approximately 90° or more
● Rear corner sensors/rear center sensors:
The shift lever is in R.
■ Sensor detection information
● The sensor detection areas are limited to the areas around the vehicle bum-
pers.
● 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.

■ Side area obstacle warning function
Obstacle notified (within the vehicle course)
● Only when obstacles on the sides are in the vehicle course will the driver be
notified (display and buzzer).
● Although the display operates while the vehicle is stopped or moving, the
buzzer only sounds during movement.
■ Obstacle detection in side areas
● Obstacles may not be detected in the side areas until the scan completes.
After the engine switch is turned to the “ON” position (vehicles without a
smart entry & start system) or IGNITION ON mode (vehicles with a smart
entry & start system), scanning completes after driving the vehicle for a
short period of time. The operation disp lay is grayed out until the scans are
completed.
● 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 this case, clean the
sensor and the system should return to normal.
If a sensor is frozen due to low temperatures, a warning message may be dis-
played or an obstacle may not be detected. When the sensor thaws out, the
system should return to normal.
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.

■ If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
The system may not operate due to the malfunction of a sensor.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: P. 776)
WARNING
■When using Toyota parking assist-sensor
Observe the following precautions to avoid an unexpected accident.
● Do not exceed the speed limit of 10 km/h (6 mph).
● The sensor 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, license plate holder, etc., are 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.

■Parallel parking assist mode operating conditions
● In order to operate the parallel parking assist mode correctly, drive slowly (at
a speed at which the vehicle can be quickly stopped) parallel to the road (or
shoulder) while maintaining a distance of approximately 1 m (3.3 ft.) to any
parked vehicles.
● The function cannot be used when the vehicle speed is approximately
30 km/h (19 mph) or higher.
● The front side sensors and rear side sensors are used to detect parked
vehicles and determine the parking spot. Therefore, when detection is not
possible ( P. 460), guidance is not issued.
● If there are no parked vehicles, the parking spot cannot be determined.
Therefore, the parallel parking assist mode cannot be operated.
● If unable to detect the environment surrounding the parking space, the par-
allel parking assist mode may not be able to operate.

NOTICE
●If the road surface has any dips or inclines, the target parking spot cannot
be correctly set. Therefore, the vehicle may be parked at an angle or may
deviate from the parking spot. In these cases, do not use the parallel park-
ing assist mode.
● When there is a wall or other obstacle on the inner side of the parking
space, or when another parked vehicle extends into the road from its park-
ing spot, the target parking spot may be set in a position that juts out
slightly into the road.
● Depending on the surrounding environment, such as other parked vehi-
cles, the vehicle may be parked at an angle or may deviate from the park-
ing spot. Manually adjust vehi cle alignment as necessary.
● It may not be possible to detect objects that are low to the ground. Directly
confirm the safety of your surroundings and, if it seems the vehicle may
make contact with an obstacle, stop the vehicle by depressing the brake
pedal.
● The sensors may not be able to detect
curbs. The vehicle may drive onto the
curb depending on the situation, such
as if a vehicle in front or back of the
parking space has driven on the curb.
Check the surrounding area to prevent
the tires and wheels from being dam-
aged.
