●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 vehicle -to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake pedal (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 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

◆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 suddenly,
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 pedal
is depressed when the system detects 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 Ve hicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery
road surfaces by controllin g steering performance.
◆Secondary Collision Brake
When the airbag sensor detects a collision, the brakes and brake
lights are automatically controlled to reduce the vehicle speed and
that helps reduce the possibility of further damage due to a second-
ary collision
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
Driving assist systems
To keep driving safety and performance, the following systems
operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too he avily 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 when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases
■ Secondary Collision Brake operating conditions
The vehicle speed is approximately 6 m ph (10 km/h) or more and the airbag
sensor detects a collision. (The Secondary Collision Brake will not operate
when the vehicle speed is below approximately 6 mph [10km/h].)
■ 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 system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this 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.

2904-5. Using the driving support systems
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 Traffic 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 lever is oper-
ated.
RCTA function:
When a vehicle approaching from the right or left rear of the vehicle is
detected, the outside rear view mirror indicators flash.

■ 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

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 s pot), and advises the driver of the
vehicles existence vi a the outside rear view mirror indicator.
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.
BSM function
●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.
291) 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. 294) satisfied for approxi-
mately 10 minutes.

●Guardrails, walls, signs, parked vehicles and similar stationary objects\
*
●Following vehicles that are in the same lane*
●Vehicles driving 2 lanes across from your vehicle*
*
: Depending on the conditions, detection of a vehicle and/or object may
occur.
■ Conditions under which the BSM function may not function correctly
●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 sensor or its
surrounding area
• During bad weather such as heavy rain, fog, snow, etc.
• When ice or mud, etc., is attached to the rear bumper
• When driving on a road surface that is wet due to rain, standing water, snow, etc.
• When there is a significant difference in speed between your vehicle 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
• 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 at about the same speed as your vehicle
• When there is a significant difference in height between your vehicle and
the vehicle that enters the detection area
• Directly after the BSM function is turned on
● 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 sensor 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 across from your vehicle enters the detection area
• When items such as a bicycle carrier are installed on the rear of the vehi-
cle

The RCTA functions when your vehi cle is in reverse. It can detect
other vehicles approaching from the ri ght or left rear of the vehicle. It
uses radar sensors to alert the driv er of the other vehicle’s existence
through flashing the outside rear vi ew mirror indicators and sounding
a buzzer.
