■Dynamic radar cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been sele cted.
● Vehicle speed is at or above approximately 30 mph (50 km/h).
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicl e distance
control mode, the vehicle speed may decrease below the set spee d in order
to maintain the distance to the preceding vehicle.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically cance led in the fol-
lowing situations:
● Actual vehicle speed falls at or 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.
● When snow mode is set.
● The sensor cannot detect correctly because it is covered in some way.
● Pre-collision braking is activated.
If vehicle-to-vehicle distance control mode is automatically ca nceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

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. ( P. 593)
■ 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. 299) 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

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.

■ Outside rear view mirror indicator visibility
In strong sunlight, the outside rear view mirror indicator may be difficult to
see.
■ Hearing the RCTA buzzer
The RCTA buzzer may be difficult to hear over loud noises, such as if the
audio system volume is high.
■ When there is a malfunction in the Blind Spot Monitor
If a system malfunction is detected due to any of the following , a warning
message will be displayed: ( P. 593)
● A sensor is malfunctioning
● A sensor is dirty or covered with snow or a sticker
● The outside temperature is extremely high or low
● Sensor voltage is abnormal
● A sensor is misaligned

WARNING
■Handling the radar sensor
Blind Spot Monitor sensors are installed behind the left and ri ght sides of the
rear bumper respectively. Observe the following to ensure the B lind Spot
Monitor can function correctly.
● Do not subject a sensor or its surrounding area on the rear bum per 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 stickers to the sensor or surrounding area on the rear
bumper.
● 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.
593) will be displayed. In this situation,
clear off the dirt or snow and drive the
vehicle with the operation conditions of
the BSM function ( P. 329) satisfied for
approximately 10 minutes. If the warn-
ing message does not disappear, have
the vehicle inspected by your Toyota
dealer.

The BSM function uses radar sensors to detect vehicles that are trav-
eling in an adjacent lane in the area that is not reflected in the outside
rear view mirror (the blind spot), and advises the driver of th e vehicles
existence via the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to: Approximately 11.5 ft. (3.5 m)
from the side of the vehicle
The first 1.6 ft. (0.5 m) from the
side of the vehicle is not in the
detection area
Approximately 9.8 ft. (3 m) from
the rear bumper
Approximately 3.3 ft. (1 m) for-
ward of the rear bumper

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The BSM function is a supplementary 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 th e BSM function.
As the function cannot judge if it is safe to change lanes, ove r reliance could
lead to an accident resulting in death or serious injury.
As the system may not function correctly under certain conditions, the
driver’s own visual confirmation of safety is necessary.
