Starting and operating/Reverse Automatic Braking System
operation may be prioritized. In this
case, automatic braking will not oper-
ate.
. Thesystemmaynotbeableto
detect the following objects
– Sharp or thin objects such as
poles, fences and ropes which may
not reflect the sound wave emitted
from the sonar sensor
– Objects that are too close to the
rear bumper when the select lever is
set to the “R” position
– Objects with a surface which may
not reflect the sound wave emitted
from the sonar sensor such as a
chain link fence.
. Objects the system is not designed
to detect
– Pedestrians
– Moving objects including moving
vehicles
– Objects which absorb sound
waves such as cloth or snow
– Objects whose surface has a
diagonal angle
– Objects that are low to the
ground such as parking blocks
– Objects that are high above the
ground such as objects hanging
from above
. The system may not be able to
properly detect objects or may cause
a system malfunction when the follow-
ing conditions exist
High frequency sound from other
sources are nearby
– Horn sound from another vehicle
– Engine sound from other vehi-
cles
– Sound of an air brake
– Vehicle detection equipment or a
sonar from another vehicle
– A sound wave with a frequency
similar to the vehicle’s system is
transmitted nearby
– A vehicle equipped with the same
system is rever sing toward your
reversing direction
Weather conditions
– Extremely high or extremely low
temperatures in which the area near
the sonar sensor becomes too hot
or too cold to operate
– The rear bumper near the sonar
sensors is exposed to heavy rain or
a significant amount of water
– Fog, snow or sandstorm, etc.
– Air is moving rapidly such as
when a strong wind is blowing
Parts attached to the rear bumper
near the sonar sensor
– Commercial electronic parts (fog
light, fender pole, radio antenna) or
commercial attachment parts (trai-
ler hitch, bicycle carrier, bumper
guard) are attached
– Parts that emit high frequency
sound, such as a horn or speaker,
are attached
Vehicle conditions
– The vehicle is significantly in-
clined
– The ground clearance is signifi-
cantly reduced due to the vehicle’s
loading condition, etc.
– When
the sonar sensor is mis-
aligned due to a collision or an
accident
Surrounding environment
– A cloth bann er, f lag, hanging
branch or railroad crossing bars
are present in the reversing direc-
tion
– When reversing on a gravel or
grassy area
– When reversing in an area where
objects or walls are adjacent to the
vehicle such as narrow tunnels,
narrow bridges, narrow roads or
