have the system inspected.
• A sticker, paint, or a chemical is applied to the sonar sensors or the
rear bumper near the sonar sensor.
• The rear bumper is modified. • The rear bumper has been removed
and attached.
• The ground clearance is changed due to the vehicle’s loading condition or
modification.
• There is damage to the sonar sensors or the rear bumper near the sonar
sensor.
• The rear bumper is exposed to strong impact, or the rear bumper is
deformed.
●On a steep hill, the system’s auto-
matic braking ability will be reduced.
●The system is designed to avoid colli-
sions by automatic hard braking when
the vehicle’s reversing speed is less than approximately 5 km/h (3 mph).
However, the system does not guar-
antee that the vehicle will be able to avoid collisions in any situation.
●If the vehicle is reversed at an extremely slow speed, the driver’s
operation may be prioritized. In this
case, automatic braking will not oper- ate.
●The system may not be able to detect and apply the brake with 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 shift lever is set to
R. • 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 and apply brake. • Pedestrians.
• Moving objects including moving vehi-
cles. • Objects which absorbs 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.
• Objects that are out of range of the center of the vehicle in the horizontal
direction.
• Objects that are not in a vertical direc- tion.
• Objects which are not perpendicular
to the ground. • Objects which are not directly in the
traveling direction of the vehicle.
• Objects which are uneven or wavy.
●When reversing the vehicle, the func-
tions may not be able to work properly or may cause a system malfunction if
the following conditions exist.
High frequency sound from other
sources are nearby:
• Horn sound from another vehicle. • Engine sound from other vehicles.
• 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 near by.
• A vehicle equipped with the same sys-
tem is reversing toward your reversing direction.
●Weather conditions:• Extremely high or extremely low tem-
peratures in which the area near the
sonar sensor becomes too hot or too cold to operate.
• The sonar sensors or the rear bumper
near the sonar sensors are 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 com- mercial attachment parts (trailer hitch,
