BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on the
inner side of the rear bumper
on the left and right side to
assist the driver in confirming
safety when changing lanes.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for safe driving. Always drive safely, tak-
ing care to observe your surround- ings.
The Blind Spot Monitor is a supple-
mentary function which alerts the driver that a vehicle is in a blind spot of the outside rear view mirrors or is
approaching rapidly from behind into a blind spot. Do not overly rely on the
Blind Spot Monitor. As the function cannot judge if it is safe to change lanes, over reliance could lead to an
accident resulting in death or serious injury.
As the system may not function cor-
rectly under certain conditions, the driver’s own visual confirmation of safety is necessary.

4-5. Using the driving support systems
■The system can be operated when
●The engine switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●Steering wheel is turned approxi-mately 90° or more (Front side sen-sors, rear side sensors) (if equipped)
●The parking brake is released.
■If “Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be covered with water
drops, ice, snow, dirt, etc. Remove the water drops, ice, snow, dirt, etc., from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low temperatures, a warning message
may be displayed or the sensor may not be able to detect an object. Once the ice melts, the system will return to normal.
■Sensor detection information
The following situations may occur during use.
●The sensors may be able to only detect objects near the front and rear bumpers.
●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 within the sen- sor’s detection areas before the dis-play is shown and the warning beep
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 it. Pay particular attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
WARNING
●Do not modify, disassemble or paint the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.
