Approximate areas where obstacles can
be detected
80SM003
• An obstacle within about 20 cm (8 in)
from a sensor or just below a sensor is
not detectable.
• The sensors can detect an obstacle up
to about 1.5 m (5 ft) from the rear of
vehicle.
NOTE:
• Thin poles or obstacles lower than the
sensors may become undetectable as
the vehicle moves closer to them even if
they have been detected from longer
distances.
• The system may calculate the distance
to a road sign or similar obstacle to be
shorter than the actual distance.
WARNING
• Under the following conditions, the
parking sensor system may not
work normally because the sensors
cannot detect obstacles correctly.
– Sensors are covered with mud,
ice or other materials. (Such
materials must be removed for
normal operation.)

WARNING
(Continued)
– Sensors are wet from water
splashes or heavy rain.
– Sensors are covered by a hand,
sticker, accessory, etc.
– There is an accessory or other
object attached within the sen-
sor’s sensing area.
– Items such as tow hooks, com-
mercially available corner poles,
radio antenna, etc. are installed
on the bumper.
– The height of the bumper is
changed due to alteration to the
suspension or other causes.
– The sensor areas are extremely
hot from direct sunlight or cold
due to freezing weather.
– The vehicle is on a rough sur-
face, slope, gravel road or grass
field.
– The vehicle is at a steep angle.
– Sensors have intercepted ultra-
sonic noise from another vehi-
cle’s horn, engine, air braking
system (large vehicles), or park-
ing sensor.
– Obstacles are too close to the
sensors.
(Continued)
WARNING
(Continued)
– Sensors are at an angle to a
highly reflective object such as
glass. (Ultrasonic waves are not
reflected back from the obstacle.)
• Sensors may not be able to cor-
rectly detect the following types of
obstacles:
– Objects made of a thin material
such as wire netting and ropes
– Square-shaped curbstones or
other objects with sharp edges
– Tall objects with a large upper
part such as a road sign
– Low-profile objects such as curb-
stones
– Sound-absorbing objects such
as cotton and snow
