Automatic cancelation of c onstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h ) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 25 mph (40 km/h) .
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● Pre-collision braking is activated.
If constant speed control mode is automatically canceled for an y other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.
■ Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehi-
cle distance control mode, a brake system operation sound may b e heard.
This does not indicate a malfunction.
■ Warning messages and buzzers for d ynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.
■ When the sensor may not be correctly detect ing the vehicle ahead
In the case of the following and depending on the conditions, o perate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types o f vehicles, the
approach warning ( P. 265) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane
● Vehicles with small rear ends (trailers with no load on board, etc.)
● Motorcycles traveling in the same lane

When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
■ 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
●
When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding vehicle has an extremely
high ground clearance
●When the road curves or when the
lanes are narrow
● When steering wheel operation or your
position in the lane is unstable

■Outside rear view mirror indicator visibility
In strong sunlight, the outside rear view mirror indicator may be difficult to
see.
■ When “BSM Unavailable See Owner’s Manual” is shown on the multi -
information display
The sensor voltage has become abnormal, or water, snow, mud, etc., may be
attached to the rear bumper around the sensors ( P. 272). Removing the
water, snow, mud, etc., from the vicinity of the sensor area sh ould return it to
normal. Also, the sensor may not function normally when used in extremely
hot or cold weather.
■ When “Blind Spot Monitor Malfunction Visit Your Dealer” is show n on
the multi-information display
There may be a sensor malfunction or misaligned. Have the vehicle
inspected by your Toyota dealer.
■ Customization
Some functions can be customized. ( P. 558)

WARNING
■To ensure the system can operate properly
Blind Spot Monitor sensors are installed behind the left and ri ght sides of the
rear bumper respectively. Observe the following to ensure the Blind Spot
Monitor can function correctly.
● 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 si tuations,
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 stickers or install accessories to the sensor or surrounding
area on the rear bumper.
● If a sensor or the rear bumper needs to be removed/installed or replaced,
contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer.
● Do not modify the sensor or surrounding area on the rear bumper .
● Do not paint the rear bumper any color other than an official Toyota color.
●Keep the sensors and the surrounding
areas on the rear 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.
271) will be displayed. In this situation,
clear off the dirt or snow and drive the
vehicle with the operation conditions of
the Blind Spot Monitor ( P. 275) satis-
fied for approximately 10 minutes. If the
warning message does not disappear,
have the vehicle inspected by your Toy-
ota dealer.

Vehicles that can be detected
by the Blind Spot Monitor
The Blind Spot Monitor uses radar sensors to detect the followi ng
vehicles traveling in adjacent lanes and advises the driver of the
presence of such vehicles via the indicators on the outside rea r
view mirrors.
Vehicles that are traveling in a reas that are not visible using the
outside rear view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that
are not visible using the outside rear view mirrors (the blind
spots)

Conditions under which the system may not function correctly
●The Blind Spot Monitor may not detect vehicles correctly in the following sit-
uations:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When mud, snow, ice, a sticker, etc. is covering the sensor or surround-
ing area on the rear bumper
• When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching with only a small gap b etween
each vehicle
• When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your v ehicle and
the vehicle that enters the detection area
• When the difference in speed between your vehicle and another vehicle
is changing
• When a vehicle enters a detection area traveling at about the same
speed as your vehicle
• As your vehicle starts from a stop, a vehicle remains in the d etection area
• When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven
surfaces
• When vehicle lanes are wide, or when driving on the edge of a lane, and
the vehicle in an adjacent lane is far away from your vehicle
• When an accessory (such as a bicycle carrier) or towing eyelet is
installed to the rear of the vehicle
• When there is a significant difference in height between your vehicle and
the vehicle that enters the detection area
• Immediately after the Blind Spot Monitor is turned on
● Instances of the Blind Spot Monitor unnecessarily detecting a vehicle and/or
object may increase in the following situations:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When the distance between your vehicle and a guardrail, wall, etc. that
enters the detection area is short
• When driving up and down consecutive steep inclines, such as h ills, dips
in the road, etc.
• When vehicle lanes are narrow, or when driving on the edge of a lane,
and a vehicle traveling in a lane other than the adjacent lanes enters the
detection area
• When driving on roads with sharp bends, consecutive curves, or uneven
surfaces
• When the tires are slipping or spinning
• When the distance between your vehicle and a following vehicle is short
• When an accessory (such as a bicycle carrier) or towing eyelet is

Buzzer operation and di
stance to an obstacle
A buzzer sounds when the sensors are operating.
● The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the
obstacle, the buzzer sounds continuously: Approximately 1.2 ft.
(35 cm).
● When 2 or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle. If one or both
come within the above distances , the beep will repeat a long
tone, followed by fast beeps.
Approximately 2.0 ft. (60 cm)
Approximately 4.9 ft. (150 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.
