■Intelligent Clearance Sonar function while the Simple Intelligent Parking
Assist System is operating
While the Simple Intelligent Parking Assist System is operating, if the system
detects an obstacle that could result in a collision, hybrid system output
restriction control and brake control of the Intelligent Clearance Sonar func-
tion are operated, regardless of whether the Intelligent Clearance Sonar func-
tion is on or off. (P. 445)
●After the Intelligent Clearance Sonar function operates, operation of the
Simple Intelligent Parking Assist System is temporarily stopped, and opera-
tion of the Intelligent Clearance Sonar function is indicated on the multi-
information display. (P. 449)
●When operation of the Simple Intelligent Parking Assist System is stopped 3
times by operation of the Intelligent Clearance Sonar function, the Simple
Intelligent Parking Assist System is canceled.
●Once the Simple Intelligent Parking Assist System becomes available after
the Intelligent Clearance Sonar function is operated, a message prompting
you to shift is displayed on the multi-information display. Operation of the
Simple Intelligent Parking Assist System can be resumed by shifting accord-
ing to the prompt on the multi-information display and pressing the S-IPA
switch (P. 459) again.
■Shifting while the Simple Intelligent Parking Assist System is operating
If the system determines that the drivers intends to move forward or in
reverse, assistance continues even if the drivers shifted before being
prompted to do so by the system. However, because driver operation differs
from the guidance provided by the system, the number of turning maneuvers
may increase.
■Customization
Settings (e.g. the obstacle detection range) can be changed. (Customizable
features: P. 708)

■Function summary
If a parking space can be detected, you will be guided forward until
you reach the assist control starting position, and then the parallel
parking assist mode can be used. Furthermore, depending on the
parking space and other conditions, multi-turn maneuvering assist
control is also provided if necessary.
Continue moving forward
with the vehicle parallel to
the curb or road, and stop so
that the center of the target
parking spot appears nearly
perpendicular to the vehicle.
Then press the S-IPA switch
1 time to select the parallel
parking assist mode.
Travel straight ahead paral-
lel with the road or curb so
that the parking space is
detected.
A sound is issued and a display is shown to notify you when the
vehicle reaches a position where assist control can be used to
begin backing up from, and then when the shift position is
changed according to guidance provided by the system, steering
wheel auto operation begins.
If the detected parking space or road width (distance to the side of the
road across from the parking space) is narrow, or if there are obstacles
in front of the vehicle, guidance will not be issued.
