■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

◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces.
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippe ry
road surfaces by controlling steering performance.
◆Secondary Collision Brake
When the airbag sensor detects a collision and the system oper-
ates, the brakes and stop light s are automatically controlled to
reduce the vehicle speed and hel p reduce the possibility of further
damage due to a secondary collision
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicl e or accelerating on slippery roads
Driving assist systems
To keep driving safety and perf ormance, the following systems
operate automatically in respon se to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heav ily when operating the vehi-
cle.

■Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the power switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on wh en vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases
■ Secondary Collision Brake operating conditions
The system operates when the SRS airbag sensor detects a collis ion while
the vehicle is in motion.
However, the system does not operate in any of the following si tuations.
● The vehicle speed is below 6 mph (10 km/h)
● Components are damaged
■ Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situ-
ations:
●The vehicle speed drops below approximately 6 mph (10 km/h)
● A certain amount of time elapses during operation
● The accelerator pedal is depressed a large amount
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.

■ The outside rear view mirror indicators visibility
When under strong sunlight, the outside rear view mirror indica tor may be dif-
ficult to see.
■ When “Blind Spot Monitor Unavailable” is shown on the multi-inf orma-

Ice, snow, mud, etc., may be attached to the rear bumper around the sensors.
( P. 312)
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
■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.
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.
● If a sensor or the rear bumper needs to be removed/installed or replaced,
contact your Toyota dealer.
● 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.
311) 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. 315) satisfied for approxi-
mately 10 minutes.

The BSM function uses radar sensors to detect the following vehicles
traveling in an adjacent lane in the area that is usually not r eflected in
the outside rear view mirror (the blind spot), and advises the driver of
the presence of such vehicles via the indicators on the outside rear
view mirrors.
Vehicles that are traveling in areas that are not visible using the out-
side rear view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that are
not visible using the outside re ar view mirrors (the blind spots)

ing area on the rear bumper
• When there is a significant difference in speed between your v ehicle and
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

the vehicle that enters the detection area
3164-5. Using the driving support systems
• Directly after the BSM function is turned on

surrounding area
• When the distance between your vehicle and a guardrail, wall, etc. that
enters the detection area is short
• When there is only a short distance between your vehicle and a following
vehicle
• 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 items such as a bicycle carrier are installed on the rear of the vehi-
cle
