4-5. Using the driving support systems
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

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
LEXUS NX300/NX200 Owners Manual̲General̲M78540̲en
• 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
