■The BSM outside rear view mirror indicators visibility
When under strong sunlight, the outside rear view mirror indicator may be dif-
ficult to see.
■ Rear Cross Traffic Alert buzzer hearing
Rear Cross Traffic Alert function may be difficult to hear over loud noises
such as high audio volume.
■ When “Blind Spot Monitor Unavailabl e” is shown on the multi-informa-
tion display
The sensor voltage has become abnormal, water, snow mud, etc., may be
built up in the vicinity of the sensor area of bumper ( →P. 411). Removing the
water, snow, mud, etc., from the vicinity of the sensor area bumper should
return it to normal. Also, the sensor may not function normally when used in
extremely hot or cold weather.
■ When “Blind Spot Monitor System Malfunction Visit Your Dealer” is
shown on the multi- information display
There may be a sensor malfunction or misaligned. Have the vehicle
inspected by your Toyota dealer.

■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 befo\
re
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
When an obstacle in the side areas is wi thin the vehicle course while the
vehicle is moving forward or backward, this function inform the driver by the
display and the buzzer. ( →P. 422, 423)
■ Obstacle detection in side areas
●Obstacles in the side areas are detected 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. Obstacle

■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 Malfunction” is di splayed 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. 732)
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.
