■
Static objects not detected by the sen-
sors
The following static objects 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
■ Situations in which the Parking Support
Brake function (for static objects) may
not operate
When driving with the shift lever in N
■
Situations when the system may operate
even though there is no possibility of a
collision
In the following situations, the system may
operate even though there is no possibility
of a collision.
● Environmental influence
• The vehicle is driven on a narrow road
• The vehicle is driven on a gravel road or
in an area with tall grass
• The vehicle is driven toward a banner or
flag, a low-hanging branch or a boom
barrier (such as those used at railroad
crossings, toll gates and parking lots).
• There is a static object on the shoulder of
the road (when the vehicle is driven in a
narrow tunnel, on a narrow bridge or on a
narrow road)
• The vehicle is being parallel parked
• There is a rut or hole in the surface of the
road
• When the vehicle is driven on a metal
cover (grating), such as those used for
drainage ditches
• The vehicle is driven on a steep slope
• The sensor is covered by water on a
flooded road
● Influence from the weather
• Ice, snow, dirt, etc., has adhered to the
sensor (if removed, the system returns to
normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a
sand storm
● Influence from other sonic waves
• An ultrasonic wave source is nearby, such
as the horn or clearance sonar of another
vehicle, a vehicle detector, a motorcycle
engine or the air brake of a large vehicle
• Electronic components (such as a backlit
license plate (especially fluorescent
types), fog lights, a fender pole or a wire-
less antenna) are installed near the sen-
sors
● Changes in the vehicle
• The vehicle is tilted a large amount
• The height of the vehicle has drastically
changed due to the carried load (the
nose tilts up or down)
• The direction of the sensor has deviated
due to a collision or other impact
