WARNING
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function whi ch alerts the
driver that a vehicle is present in the blind spot. Do not over ly rely on the
Blind Spot Monitor function. The function cannot judge if it is safe to change
lanes, therefore over reliance could cause an accident resultin g in death or
serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

■The system can be operated when
● The power switch is in ON mode.
● Toyota parking assist-sensor function is on.
● The vehicle speed is less than about 10 km/h (6 mph).
● A shift lever other than P is selected.
● Vehicles with side sensors: Steering wheel is turned approximately 90° or
more
■ If “Parking assist unavailable. Clean parking assist sensor” is displayed
on the multi-information display
A sensor may be covered with ice, snow, dirt, etc. Remove the i ce, snow, dirt,
etc., from the sensor to return the system to normal.
Also, due to ice forming on a sensor at low temperatures, a war ning message
may be displayed or the sensor may not be able to detect an obj ect. Once the
ice melts, the system will return to normal.
■ If “Parking assist Malfunction Visit your dealer” is displayed on the
multi-information display
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.
■ Sensor detection information
The following situations may occur during use.
● The sensors may be able to only detect objects near the front and rear bum-
pers.
● Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.
● If an object is extremely close to a sensor, it may not be detected.
● There will be a short delay between object detection and display. Even at
low speeds, there is a possibility that the object will come wi thin the sensor’s
detection areas before the display is shown and the warning bee p sounds.
● It might be difficult to hear the buzzer due to the volume of the audio system
or air flow noise of the air conditioning system.
● It may be difficult to hear the buzzer if buzzers for other systems are sound-
ing.

■ Objects which the system may not be properly detected
The shape of the object may prevent the sensor from detecting i t. Pay partic-
ular attention to the following objects:
● Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low objects
● Tall objects with upper sections projecting outwards in the direction of your
vehicle
People may not be detected if they are wearing certain types of clothing.
■ Object warning function (vehicles with side sensors)
■ Obstacle detection in side areas (vehicles with side sensors)
● Objects in the side areas are detected while driving by scanning the side
areas with the side sensors. Recognized objects are retained in memory for
up to approximately 2 minutes.
● Objects may not be detected in the side areas until the scan completes.
After the power switch is turned to ON mode, scanning completes after driv-
ing the vehicle for a short period of time.
● When an object such as another vehicle, pedestrian or animal is detected
by the side sensors, the object may continue to be detected eve n after it has
left the side sensor detection area.
■ Situations in which the system may not operate properly
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect objects. Particular ins tances where this
may occur are listed below.
● There is dirt, snow or ice on a sensor. (Cleaning the sensors will resolve this
problem.)
● A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the sensor di splay may be dis-
played abnormally, or objects, such as a wall, may not be detec ted.
When an object in the side areas is within
the vehicle course while the vehicle is
moving forward or backward, this function
inform the driver by the display and the
buzzer.
