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

■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. 279)
■To prevent unnecessary operation of the Intelligent Clearance Sonar
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

3144-5. Using the driving support systems
If the Rear Cross Traffic Auto Brake function detects that a collision
with an approaching vehicle is possible, the hybrid system output will
be restricted to restrain any increase in vehicle speed. (Hybrid system
output restriction control: See A below.)
Additionally, if the accelerator pedal continues to be depressed, the
brakes will be applied automatically to reduce the vehicle speed.
(Brake control: See B below.)

3164-5. Using the driving support systems
■The Rear Cross Traffic Auto Brake function will operate when
The function will operate when the ICS OFF indicator is not illuminated or
flashing (P. 303, 311) and all of the following conditions are met:
●Hybrid system output restriction control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto Brake is
enabled.
• The vehicle speed is 10 mph (15 km/h) or less.
• Vehicles which are approaching from the right or left at the rear of the
vehicle at a traveling speed of less than approximately 5 mph (8 km/h)
• The shift lever is in R.
• The system determines that a stronger than normal brake operation is
necessary to avoid a collision with an approaching vehicle.
●Brake control
• Hybrid system output restriction control is operating.
• The system determines that an emergency brake operation is necessary
to avoid a collision with an approaching vehicle.
■The Rear Cross Traffic Auto Brake function will stop operating when
The function will stop operating if any of the following conditions are met:
●Hybrid system output restriction control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto Brake is
disabled.
• The collision becomes avoidable with normal brake operation.
• A vehicle is no longer approaching from the right or left at the rear of the
vehicle.
●Brake control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto Brake is
disabled.
• Approximately 2 seconds elapse after the vehicle is stopped by brake
control.
• The brake pedal is depressed after the vehicle is stopped by brake con-
trol.
• A vehicle is no longer approaching from the right or left at the rear of the
vehicle.
■Detection area of the Rear Cross Traffic Auto Brake function
The detection area of the Rear Cross Traffic Auto Brake function differs from
the detection area of the RCTA function (P. 285).
Therefore, even if the RCTA function detects a vehicle and provides an alert,
the Rear Cross Traffic Auto Brake function may not start operating.
■If the Rear Cross Traffic Auto Brake function has operated
If the vehicle is stopped due to operation of the Rear Cross Traffic Auto Brake
function, the Rear Cross Traffic Auto Brake function will be disabled and the
ICS OFF indicator will illuminate.

■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. 303), or turn the power switch off and then back to ON mode.
When the function is disabled, the ICS OFF indicator will illuminate. (P. 95)
If there is no longer a vehicle approaching from the right or left 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-enabled, 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 detect 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
●<002a005800440055004700550044004c004f0056000f0003005a0044004f004f0056000f00030056004c004a00510056000f0003005300440055004e00480047000300590048004b004c0046004f00480056000300440051004700030056004c0050004c00

: Depending on the conditions, detection of a vehicle and/or object may
occur.
■RCTA function buzzer
Regardless of whether the RCTA function is enabled or not (P. 277), if the
Rear Cross Traffic Auto Brake function is enabled and brake control 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 system may operate even though there is no
possibility of a collision
In some situations such as the following, the Rear Cross Traffic Auto Brake
function may operate even though there is no possibility of a collision.
●When there are spinning objects near your vehicle such as the fan of an air
conditioning unit
●When water is splashed or sprayed toward the rear bumper, such as from a
sprinkler ●When the parking space faces a street
and vehicles are being driven on the
street
●When a detected vehicle turns while
approaching the vehicle
●When a vehicle passes by the side of
your vehicle
●When the distance between your vehicle
and metal objects, such as a guardrail,
wall, sign, or parked vehicle, which may
reflect electrical waves toward the rear
of the vehicle, is short

(especially fluorescent type), fog lights, a fender pole or wireless 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
