WARNING
■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of
the vehicle rear bumper respectively. Observe the following to ensure the
Blind Spot Monitor can function correctly.
If the warning message does not disappear, have the vehicle inspected
by your Toyota dealer
● Do not subject a sensor or its surrounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off position, the system may malfunction
and vehicles may not be detected correctly.
In the following situations, have your vehicle inspected by your Toyota
dealer.
• A sensor or its surrounding area is subject to a strong impact .
• If the surrounding area of a sensor is scratched or dented, or part of them has become disconnected.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
● Do not modify the sensor or surrounding area on the bumper.
● Do not paint the rear bumper any color other than an official Toyota color.
●Keep the sensor and its surrounding
area on the bumper clean at all times. If
a sensor or its surrounding area on the
rear bumper is dirty or covered with
snow, the Blind Spot Monitor may not
operate and a warning message will be
displayed. ( P. 280)
In this situation, clear off the dirt or
snow and drive the vehicle with the
operation conditions of the BSM func-
tion satisfied for approximately 60 min-
utes.

WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an object. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or objects may not be detected.
● The sensor is covered in any way.
● The vehicle is leaning considerably to one side.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● The vicinity of the vehicle is noisy due to vehicle horns, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● There is another vehicle equipped with parking assist sensors in the vicin-
ity.
● The sensor is coated with a sheet of spray or heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is equipped with a fender pole or wireless antenna.
● Towing eyelets are installed.
● The bumper or sensor receives a strong impact.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● In harsh sunlight or intense cold weather.
● The area directly under the bumpers is not detected.
● If objects draw too close to the sensor.
● A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
● A backlit license plate is installed.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

WARNING
■Hill- start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered wit h ice.
● Unlike the parking brake, hill-st art assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the TRAC/VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC systems off unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfunction.
■ Secondary Collision Brake
Do not rely solely upon the Secondary Collision Brake. This system is
designed to help reduce the possibility of further damage due to a second-
ary collision, however, that effect changes according to variou s conditions.
Overly relying on the system may result in death or serious inj ury.
