■Situations in which the Intelligent Clearance Sonar function may operate even if there is no possibility of a collision
In some situations such as the following, the Intelligent Clearance Sonar function may
operate even though there is no possibility of a collision.
●Vehicle surroundings
• When driving toward a banner, flag, low- hanging branch or boom barrier (such as those used at railroad crossings, toll gates and parking lots).• When driving on a narrow path surrounded by a structure, such as in a tunnel or on
an iron bridge) • When parallel parking• When there is a rut or hole in the surface of the road
• When driving on a metal cover (grating), such as those used for drainage ditches • When driving on a steep slope
• If a sensor is hit by a large amount of wa ter, such as when driving on a flooded road
●Weather
• If a sensor is covered with ice, snow, dirt, etc. (when cleared, the system will return to normal)• If heavy rain or water strikes a sensor
• When driving in inclement weather su ch as fog, snow or a sandstorm
●Other ultrasonic waves sources
• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of large vehi- cles, the clearance sonar of other vehicles or other devices which produce ultra-sonic waves are near the vehicle
• If a sticker or an electronic component, such as a backlit license plate (especially flu- orescent type), fog lights, a fender pole or wireless antenna is installed near a sensor
●Changes in the vehicle posture
• If the vehicle is significantly tilted • If the front of the vehicle is raised or lowered due to the carried load
• If the orientation of a sensor has been changed due to a collision or other impact
• When driving on a narrow road
• When driving on a gravel road or in an area with tall grass

■If the Intelligent Clearance Sonar function operates unnecessarily such as at a railroad crossing
Even in the event that the Intelligent Cleara nce Sonar function operates unnecessarily,
such as at a railroad crossing, brake contro l will be canceled after approximately 2 sec- onds, allowing you to proceed forward and leave the area, Brake control can also be canceled by depressing the brake pedal. Depressing the accelerator pedal again will
allow you to proceed forward and leave the area.
■Situations in which the Intelligent Cleara nce Sonar Brake function may not operate properly
In some situations such as the following , this function may not operate properly.
●Weather
• If a sensor is covered with ice, snow, dirt, etc. (when cleared, the system will return to normal)
• If heavy rain or water strikes a sensor • When driving in inclement weather su ch as fog, snow or a sandstorm
●Vehicle surroundings
• When an object that cannot be detected is between the vehicle and a detected object
• If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front of the vehicle or runs out from the side of the vehicle.
●Other ultrasonic waves sources
• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of large vehi- cles, the clearance sonar of other vehicles or other devices which produce ultra-
sonic waves are near the vehicle • If a sticker or an electronic component, such as a backlit license plate (especially flu-orescent type), fog lights, a fender pole or wireless antenna is installed near a sensor
●Changes in the vehicle posture
• If the vehicle is significantly tilted
• If the front of the vehicle is raised or lowered due to the carried load • If the orientation of a sensor has been changed due to a collision or other impact
• When a sensor or the area around a sensor is extremely hot or cold
• When strong winds are blowing

If the Rear Crossing Traffic Auto Brake function detects that a collision with an
approaching vehicle is possible, the engine output will be restricted to restrain
any increase in vehicle speed. (Engine output restriction control: See A below.)
Additionally, if the accelerator pedal cont inues to be depressed, the brakes will
be applied automatically to reduce the vehicle speed. (Brake control: See B
below.)

■The Rear Crossing Traffic Auto Brake function will operate when
The function will operate when the ICS OFF indicator is not illuminated or flashing ( P. 383, 391) and all of the following conditions are met:
●Engine output restriction control
• The Intelligent Clearance Sonar with Rear Crossing Traffic Auto Brake is enabled. • The vehicle speed is 15 km/h (10 mph) or less.• 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
• Engine 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 Crossing Traffic Auto Brake function will stop operating when
The function will stop operating if an y of the following conditions are met:
●Engine output restriction control
• The Intelligent Clearance Sonar with Rear Crossing 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 Crossing 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 control.
• A vehicle is no longer approaching from the right or left at the rear of the vehicle.
■Detection area of the Rear Cro ssing Traffic Auto Brake function
The detection area of the Rear Crossing Tr affic Auto Brake function differs from the
detection area of the RCTA function ( P. 367).
Therefore, even if the RCTA function detects a vehicle and provides an alert, the Rear Crossing Traffic Auto Brake function may not start operating.
■If the Rear Crossing Traffic Auto Brake function has operated
If the vehicle is stopped due to operation of the Rear Crossing Traffic Auto Brake func- tion, the Rear Crossing Traffic Auto Brake fu nction will be disabled and the ICS OFF indi-
cator will illuminate.

■Re-enabling the Rear Crossing Traffic Auto Brake function
To re-enable the Rear Crossing Traffic Auto Brake function when it is disabled during
operation of the Rear Crossing Traffic Auto Brake function, either enable the system
again ( P. 383), or turn the engine switch o ff and then back to IGNITION ON mode.
Additionally, if there is no longer a vehicle ap proaching from the right or left at the rear of
the vehicle, or if the traveling direction of the vehicle changes (such as changing from
moving forward to backing up or from backing up to moving forward), the system will be
re-enabled automatically.
■Conditions under which the Rear Crossing Traffic Auto Brake function will not detect a
vehicle
The Rear Crossing Traffic Auto Brake function is not designed to detect the following
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 vehi cles and similar stationary objects*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
●Vehicles approaching from the parking spaces next to your vehicle*
*
: 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. 357), if the Rear Cross-
ing Traffic Auto Brake function is enabled an d brake control is performed, 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

The rear view image is displayed when
the shift lever is in R and the engine
switch is in IGNITION ON mode.
The parking assist monitor system will be deactivated when the shift lever is inany position other than R.
When the shift lever is shifted to R and any mode button (such as “MENU”) ispressed, the parking assist monitor sys-
tem is canceled, and the screen is switched to the mode of the button thatwas pressed.

: If equipped
The parking assist monitor assists the driver by displaying an image of the view
behind the vehicle while backing up, for example while parking.
The screen illustrations used in this text are intended as examples, and may
differ from the image that is ac tually displayed on the screen.
