S-APGS (Simple Adva nced 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. (Changing the shift position and speed adjust-
ment when moving forward or backing up are not performed
automatically.)
● The Simple Advanced Parking Gu idance 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. 444)

● 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. 445) to turn the system off.

■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
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-APGS
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 prov ided 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.
Parking is complete
This completes the assist mode. Depending on the condition of the
parking space, guidance to starting points for moving forward and back-
ing up, as well as the steering wheel auto operation, are repeated any
time multi-turn maneuvering is necessary following step from the
time the vehicle begins backing up until parking completes.

slowly back up while adjusting your speed by depressing the
brake pedal.
● When backing up too quickly, a sharp beeping sound is emit-
ted and assist control is stopped. ( →P. 469)
● When the vehicle cannot be cleanly entered within the target
parking spot on the first try and multi-turn maneuvering is nec-
essary, proceed to step .
When multi-turn maneuvering is not necessary, proceed to
