■Conditions under which the vehic le-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake peda l (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge
● While the vehicle speed is decreasing to the set speed after th e vehicle
accelerates by depressing the accelerator pedal
■ Situations in which the curve sp eed reduction function may not operate
properly
In situations such as the following, the curve speed reduction function may
not operate properly:
● When the vehicle is being driven around a curve on an incline/d ecline
● When the course of the vehicle differs from the shape of the cu rve
● When the vehicle speed is excessively high when entering a curv e
● When the steering wheel is suddenly operated
●
When the road curves or when the
lanes are narrow
● When steering wheel operation or your
position in the lane is unstable

The Blind Spot Monitor is a system that has 2 functions;
● The BSM (Blind Spot Monitor) function
Assists the driver in making a decision when changing lanes
● The RCTA (Rear Cross T raffic Alert) function
Assists the driver when backing up
These functions use same sensors.

BSM function:
When a vehicle is detected in the blind spot, the outside rear view mirror
indicator comes on while the turn signal lever is not operated and the out-
side rear view mirror indicator flashes while the turn signal l ever is oper-
ated.
RCTA function:
When a vehicle approaching from the right or left rear of the v ehicle is
detected, the outside rear view mirror indicators flash.

■The outside rear view mirror indicators visibility
When under strong sunlight, the outside rear view mirror indica tor may be dif-
ficult to see.
■ RCTA buzzer hearing
RCTA function may be difficult to hear over loud noises such as high audio
volume.
■ When “Blind Spot Monitor Unava ilable” or “Rear Cross Traffic Alert
Unavailable” are shown on the multi-information display
Ice, snow, mud, etc., may be attached to the rear bumper around the sensors.
( P. 300)
The system should return to normal operation after removing the ice, snow,
mud, etc., from the rear bumper. Additionally, the sensors may not operate
normally when driving in extremely hot or cold environments.
■ When there is a malfunction in the Blind Spot Monitor
If a system malfunction is detected due to any of the following reasons, a
warning message will be displayed:
● There is a malfunction with the sensors
● The sensors have become dirty
● The outside temperature is extremely high or low
● The sensor voltage has become abnormal

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 you r 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 ( P.
298) will be displayed.
In this situation, clear off the dirt or
snow and drive the vehicle with the
operation conditions of the BSM func-
tion ( P. 302) satisfied for approxi-
mately 60 minutes.

The BSM function uses radar sensors to detect vehicles that are trav-
eling in an adjacent lane in the area that is usually not reflected in the
outside rear view mirror (the blind spot), and advises the driv er of the
vehicles existence vi a the outside rear vie w mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area is: Approximately 1.6 ft. (0.5 m) to 11.5 ft. (3.5 m) from either s ide of
the vehicle
The area between the side of the vehicle and 1.6 ft. (0.5 m) from the side
of the vehicle cannot be detected.
Approximately 3.3 ft. (1 m) f orward of the rear bumper
Approximately 9.8 ft. (3 m) from the rear bumper
Approximately 9.8 ft. (3 m) to 19 7 ft. (60 m) from the rear bumper
The greater the difference in speed between your vehicle and th e
detected vehicle is, the farther away the vehicle will be detec ted,
causing the outsi de rear view mirror indicator to illuminate or flash.

■Conditions under which the BSM function will not detect a vehic le
The BSM function is not designed to detect the following types of vehicles
and/or objects:
● Small motorcycles, bicycles, pedestrians, etc.
*
●Vehicles traveling in the opposite direction
● Guardrails, walls, signs, parked vehicles and similar stationar y objects
*

occur.
■ Conditions under which the BSM function may not function correc tly
● The BSM function may not detect vehicles correctly in the following condi-
tions:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• During bad weather such as heavy rain, fog, snow, etc.

ing area on the rear bumper
• When driving on a road surface that is wet due to rain, standi ng water,
snow, etc.

the vehicle that enters the detection area
• When a vehicle is in the detection area from a stop and remains in the detection area as your vehicle accelerates
• When driving up or down consecutive steep inclines, such as hills, a dip in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven
surfaces
• When multiple vehicles approach with only a small gap between each vehicle
• When vehicle lanes are wide, and the vehicle in the next lane is too far
away from your vehicle
• When the vehicle that enters the detection area is traveling a t about the
same speed as your vehicle
• When there is a significant difference in height between your vehicle and

• Immediately after the BSM function is turned on

3044-5. Using the driving support systems
●Instances of the BSM function unnecessarily detecting a vehicle and/or
object may increase under the following conditions:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When there is only a short distance between your vehicle and a guardrail,
wall, etc.
• When there is only a short distance between your vehicle and a following
vehicle
• When vehicle lanes are narrow and a vehicle driving 2 lanes ac ross from
your vehicle enters the detection area
• When driving on roads with sharp bends, consecutive curves, or uneven
surfaces
• When items such as a bicycle carrier are installed on the rear of the vehi-
cle
The RCTA functions when your vehicle is in reverse. It can dete ct
other vehicles approaching from the right or left rear of the v ehicle. It
uses radar sensors to alert the driver of the other vehicle’s existence
through flashing the outside rear view mirror indicators and so unding
a buzzer.
