NOTICE
■To prevent the system from malfunctioning
● If the area around a sensor is subjected to an impact, the system may not
operate properly due to the sensor being misaligned. Have the vehicle
inspected by your Toyota dealer.
● When using a high pressure washer to wash the vehicle, do not spray the
sensors directly, as doing so may cause a sensor to malfunction .
● When using steam to clean the vehicle, do not direct steam too close to
the sensors as doing so may cause a sensor to malfunction.
■ To prevent a radar sensor from malfunctioning
● If the area around a radar sensor is subjected to an impact, the system
may not operate properly due to a sensor malfunction. Have the vehicle
inspected by your Toyota dealer.
● Observe the radar sensor handling precautions. ( P. 300)
■ To prevent unnecessary operation of the Intelligent Clearance S onar
system
In the following situations, disable the Intelligent Clearance Sonar system
as the system may operate even though there is no possibility of a collision.
● When inspecting the vehicle using a chassis roller, chassis dynamo or free
roller
● When loading the vehicle onto a boat, truck or other transport vessel
● If the suspension has been modified or tires of a size other than specified
are installed
● If the front of the vehicle is raised or lowered due to the carried load
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or
snow plow
● When using an automatic car wash

■Re-enabling the Rear Cross Traffic Auto Brake function
To re-enable the Rear Cross Traffic Auto Brake function when it is disabled
while it is operating, either enable the Intelligent Clearance Sonar system
again ( P. 324), or turn the power switch off and then back to ON mode.
When the function is disabled, the ICS OFF indicator will illum inate. (P. 95)
If there is no longer a vehicle approaching from the right or l eft at the rear of
the vehicle when backing up, or if the traveling direction of the vehicle
changes (such as changing from backing up to moving forward), the system
will be re-enabled automatically. When the function is re-enabl ed, the ICS
OFF indicator will turn off.
■ Conditions under which the Rear Cross Traffic Auto Brake function will
not detect a vehicle
The Rear Cross Traffic Auto Brake function is not designed to d etect the fol-
lowing types of vehicles and/or objects.
● Vehicles approaching from directly behind
● Vehicles backing up in a parking space next to your vehicle
● Guardrails, walls, signs, parked vehicles and similar stationar y objects
*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
● Vehicles approaching from the parking spaces next to your vehic le
*
*
: Depending on the conditions, detection of a vehicle and/or obj ect may
occur.
■ RCTA function buzzer
Regardless of whether the RCTA function is enabled or not ( P. 298), if the
Rear Cross Traffic Auto Brake function is enabled and brake con trol is per-
formed, a buzzer will sound to notify the driver. ● Vehicles that the sensors cannot detect
due to obstructions
● Vehicles which suddenly accelerate or
decelerate near your vehicle

■Situations in which the Rear Cross Traffic Auto Brake function may not
operate properly
In some situations such as the following, this function may not operate prop-
erly.
● Objects and vehicles which the radar sensors are not designed t o detect
• Stationary objects
• Vehicles which are moving away from your vehicle
• Pedestrians, motorcycles, bicycles, etc.
*
• Objects which are extremely close to a radar sensor
• Vehicles which are approaching from the right or left at the r ear of the
vehicle at a traveling speed of less than approximately 5 mph ( 8 km/h)
• Vehicles which are approaching from the right or left at the r ear of the
vehicle at a traveling speed of more than approximately 15 mph (24 km/h)
*: Depending on conditions, detection of a vehicle and/or object may occur.
● Situations in which the radar sensors may not be able to detect an object
• When a sensor or the area around a sensor is extremely hot or cold
• If the rear bumper is covered with ice, snow, dirt, etc.
• If heavy rain or water strikes the vehicle
• When the detection area of a radar sensor is obstructed by an adjacent
vehicle
• If the vehicle is significantly tilted
• When equipment that may obstruct a sensor is installed, such a s a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
• If the suspension has been modified or tires of a size other than specified
are installed
• If the front of the vehicle is raised or lowered due to the ca rried load
• If a sticker or an electronic component, such as a backlit license plate
(especially fluorescent type), fog lights, a fender pole or wir eless antenna
is installed near a radar sensor
• If the orientation of a radar sensor has been changed due to a collision or
other impact or removal and installation
• When multiple vehicles are approaching with only a small gap between each vehicle
• When a vehicle is approaching at high speed
● Situations in which the radar sensor may not detect a vehicle
• When a vehicle approaches from the
right or left at the rear of the vehicle
while you are turning while backing
up
• When turning while backing up

■Handling the radar sensors
P. 300• When backing out of a shallow angle
parking spot
• Vehicles that the sensors cannot detect due to obstructions
• When backing up on a slope with a sharp change in grade
• When a vehicle turns into the detec- tion area

◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆The Secondary Collision Brake
When the SRS airbag sensor detects a collision and the system
operates, the brakes and stop li ghts are automatically controlled to
reduce the vehicle speed and hel p reduce the possibility of further
damage due to a secondary collision.
The slip indicator light will flash
while the TRAC/VSC/ABS sys-
tems are operating.
If the vehicle gets stuck in mud, dirt or snow, the TRAC system may
reduce power from the hybrid sys tem to the wheels. Pressing to
turn the system off may make it easier for you to rock the vehicle in
order to free it.
To turn the TRAC system off,
quickly press and release .
The “Traction Control Turned Off”
will be shown on the multi-informa-
tion display.
Press again to turn the sys-
tem back on.

■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 system is automatically canceled in any of the following si tuations.
● 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.
