• Shift position is not in P
• Vehicle speed is approximately 6 mph (10 km/h) or less
● Front side sensors/rear side sensors:
• Shift position is not in P
• Vehicle speed is approximately 6 mph (10 km/h) or less
• Steering wheel is turned approximately 90 ° or more
● Front center sensors:

■ Clearance sonar pop-up display
→P. 361
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
● Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.
● Obstacles may not be detected if they are too close to the sensor.
● There will be a short delay between obstacle detection and display. Even
when traveling at a low speed, if you come too close to an obstacle befo\
re
the display and buzzer activate, the display and buzzer may not activate at
all.
● Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
● It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.

S-APGS (Simple Advanced Parking Guidance
System)
∗
■Function summary
The Simple Advanced Parking Guidance System automatically
operates the steering wheel to provide support when backing into
an area near a target parking spot, and when departing from a par-
allel parking spot. (Shift lever operations and speed adjustment
when moving forward or backing up are not performed automati-
cally.)
●The Simple Advanced Parking Guidance System does not park
the vehicle automatically. It is a system that provides support
when pulling out of a perpendicular or parallel parking spot.
● The Simple Advanced Parking Guidance System provides steer-
ing wheel operation assistance to guide the vehicle toward the
selected intended parking spot. The selected intended parking
spot may not always be reach able, depending on road and vehi-
cle conditions at the time of parking, and the distance to the
intended parking spot.
■Linking with the Intelligent Clearance Sonar function
While the Simple Advanced Parking Guidance System is operating,
if the system detects an obstacle that could result in a collision, the
emergency brakes operat e, regardless of whether the Intelligent
Clearance Sonar function is on or off. ( →P. 359)

WARNING
●When backing up or proceeding forward, be sure to directly confirm the
safety of the area to the front or rear, and the area around the vehicle, and
slowly back up or proceed forward while adjusting the vehicle speed by
depressing the brake pedal.
● If it seems the vehicle may make contact with a pedestrian, another vehi-
cle or any other obstacles, stop the vehicle by depressing the brake pedal,
and then press the S-APGS switch ( →P. 360) to turn the system off.

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-

■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.

pressed. ( →P. 360)
● When the shift position is not in D or B, or when the vehicle
speed has been detected, pressing the S-APGS switch will not
cause the screen to switch to the “Back-in Parking” display.
● The turn signal lever ( →P. 240) can be operated to select
whether you would like to park to the left or right.
