●When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle

● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ult rasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandst orm
● When an object that cannot be detected is between the vehicle a nd 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
● If the orientation of a sensor has been changed due to a collis ion or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the car ried load
● If the vehicle cannot be driven in a stable manner, such as whe n the vehicle
has been in an accident or is malfunctioning

may operate even though there is no possibility of a collision.
● When inspecting the vehicle using a chassis roller, chassis dynamo or free
roller
● When loading the vehicle onto a boat, truck or other transport vessel
● If the suspension has been modified or tires of a size other than specified
are installed

■ To ensure the system can operate properly
 P. 450
■ Handling the suspension
Do not modify the suspension, as changes to the height or incli ne of the
vehicle may prevent the sensors from correctly detecting obstac les, may
cause the system not operate, or may cause the system to operat e unnec-
essarily.
■ If the Parking Support Brake function (static objects) operates unnec-
essarily, such as at a railroad crossing

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 int o
an area near a target parking spot, and when departing from a par-
allel parking spot. (Changing the shift position and speed adju st-
ment when moving forward or backing up are not performed
automatically.)
● 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 Parki ng Support Brake function
While the Simple Advanced Parking Guidance System is operating,
if the system detects an obstacl e that could result in a collision, the
emergency brakes operate, regardl ess of whether the Parking Sup-
port Brake function is on or off. ( P. 464)

● If it seems the vehicle may make contact with a pedestrian, ano ther vehi-
cle or any other obstacles, stop the vehicle by depressing the brake pedal,
and then press the S-APGS switch ( P. 465) to turn the system off.
