■Operation starting conditions
When the ICS OFF indi cator is not illuminated or flashing ( →P. 354,
663) and all of the following conditions are met, the system operates.
Hybrid system output restriction control
● The Intelligent Clearance Sonar is on.
● The vehicle speed is 10 mph (15 km/h) or less.
● There is an obstacle in the trav eling direction of the vehicle (6
to 13 ft. [2 to 4 m ahead]).
● The system determined that a stronger-than-normal brake
operation was necessar y to avoid a collision.
Brake control
●Hybrid system output restrict ion control is being performed.
● The system determined that an emergency brake operation
was necessary to avoid a collision.
■Operation ending conditions
In any of the following situations, the system stops operating.
Hybrid system output restriction control
● The Intelligent Clearance Sonar function has been turned off
(stopped).
● The collision became avoidable with normal brake operation.
● The obstacle is no longer in th e traveling direction of the vehi-
cle (6 to 13 ft. [2 to 4 m ahead]).
Brake control
● The Intelligent Clearance Sonar function has been turned off
(stopped).
● Approximately 2 seconds elap sed after the vehicle was
stopped by brake control.
● The brake pedal was depressed after the vehicle was stopped
by brake control.
● The obstacle is no longer in th e traveling direction of the vehi-
cle (6 to 13 ft. [2 to 4 m ahead]).

■Sensor detection range
The detection range of the Intelligent Clearance Sonar function differs from
the detection range of the clearance sonar ( →P. 337).
Therefore, even if the clearance sonar detects an obstacle and provides a
warning, the Intelligent Clearance Sonar may not start operating.
■ System operation
When the vehicle is stopped by system operation, the Intelligent Clearance
Sonar function stops and the ICS OFF indicator illuminates.
■ System recovery
When the Intelligent Clearance Sonar function is stopped by system opera-
tion and you would like to resume operation, either turn the Intelligent Clear-
ance Sonar ON again ( →P. 333), or turn the power switch off and then back
on. Furthermore, when the vehicle moves with an obstacle no longer in the
traveling direction of the vehicle, or when the traveling direction of the vehicle
changes (such as when switching from moving forward to backing up, and
vice versa), system operation automatically resumes.
■ Obstacles not detected by the sensors
The following obstacles may not be detected by the sensors.
●Objects such as people, cloth and snow, that are difficult for sonic waves to
reflect off of. (In particular, people may also not be detected depending on
the type of clothing they are wearing.)
● Objects not perpendicular with the ground, objects not at a right angle to the
traveling direction of the vehicle, uneven objects or waving objects
● Low objects
● Thin objects such as wires, fences, ropes and signposts
● Objects that are extremely close to the bumper
■ Clearance sonar buzzer
Regardless of whether the clearance sonar is on or off ( →P. 333), if the Intel-
ligent Clearance Sonar function is not stopped ( →P. 346), when the front or
rear sensors detect an obstacle and brake control is performed, the clearance
sonar buzzer also sounds and a notification of the approximate distance to
the obstacle is provided.

Assist mode will be canceled or stopped in the following cases.
■Assist control is canceled when
●The system temperature preservation function operates
● There is a system malfunction
● System determined that the parki ng environment is not suitable
for assist to continue
When assist control is canceled, firmly grasp the steering wheel,
depress the brake pedal and stop the vehicle.
Start again from the beginning, as the system will already be can-
celed. When continuing to park manually, operate the steering
wheel as you normally would.
■Assist control is stopped when
● The steering wheel is operated
● The vehicle speed exceeds 4 mph (7 km/h) during assist control
● The Intelligent Clearance Sonar function operates
When assist control is stopped, it can be resumed by following the
guidance shown on the screen.
■ If the vehicle speed is about to exceed the speed limit during assist con-
trol
Canceling or stopping assist mode
A buzzer sounds and the message indi-
cating there is possibility that the vehicle
speed may exceed the speed limit.
When the message is displayed, immedi-
ately depress the brake pedal to deceler-
ate. If the vehicle continues to accelerate,
assist control will be canceled when the
vehicle speed exceeds a certain speed.

■Function summary
Stop so that the center of the target parking spot appears nearly
perpendicular to the vehicle. If t he space is detectable, the forward
guidance function can be used. Furthermore, depending on the
parking space and other condition s, multi-turn maneuvering assist
control is also provided if necessary.
Stop so that the center of the
target parking spot appears
nearly perpendicular to the
vehicle. Then press the
S-APGS switch 2 times to
select back-in parking assist
mode.
Steering wheel auto opera-
tion starts when the vehicle
begins to move.
A sound is issued and a dis-
play is shown to notify you
when the vehicle reaches the
position to start backing up
from.
If the detected parking space or
road width (distance to the side
of the road across from the park-
ing space) is narrow, or if there
are obstacles in front of the vehi-
cle, guidance will not be issued.
Parking is complete
This completes the assist mode.
Depending on the condition of the parking space, guidance to starting
points for moving forward and backing up, as well as the steering wheel
auto operation, are repeated any time multi-turn maneuvering is neces-
sary following step from the time the vehicle begins backing up until
parking completes.

■Function summary
If a parking space can be detected, you will be guided forward until
you reach the assist c ontrol starting position, and then the parallel
parking assist mode can be used. Furthermore, depending on the
parking space and other condition s, multi-turn maneuvering assist
control is also provided if necessary.
Continue moving forward
with the vehicle parallel to

vided by the system, steering
wheel auto operation begins.
If the detected parking space or road width (distance to the side of th\
e
road across from the parking space) is narrow, or if there are obstacles
in front of the vehicle, guidance will not be issued.
