Driving
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of
your vehicle
■Situations in which the system may
not operate properly
Certain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect
objects. Particular instances where this
may occur are listed below.
●There is dirt, snow, water drops or ice
on a sensor. (Cleaning the sensors
will resolve this problem.)
●A sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor
is frozen the sensor display may be
displayed abnormally, or objects, such
as a wall, may not be detected.
●When a sensor or the area around a
sensor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of
other vehicles or other devices which
produce ultrasonic waves are near the
vehicle
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the sensor.
●Pedestrians that are hard to reflect
ultrasonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpendicu-lar to the ground, not perpendicular to
the vehicle traveling direction,
uneven, or waving are in the detection
range.
●Strong wind is blowing
●When driving in inclement weather
such as fog, snow or a sandstorm
●When an object that cannot be
detected is between the vehicle and a
detected object
●If an object such as a vehicle, motor-
cycle, bicycle or pedestrian cuts in
front of the vehicle or runs out from
the side of the vehicle
●If the orientation of a sensor has been
changed due to a collision or other
impact
●When equipment that may obstruct a
sensor is installed, such as a towing
eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier,
or snow plow
●If the front of the vehicle is raised or
lowered due to the carried load
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or is
malfunctioning
●When a tire chains, compact spare tire
or an emergency tire puncture repair
kit is used
■Situations in which the system may
operate even if there is no possibil-
ity of a collision
In some situations, such as the follow-
ing, the system may operate even
though there is no possibility of a colli-
sion.
●When driving on a narrow road

low-hanging branch or boom barrier (such as those used at railroad cross-ings, toll gates and parking lots)
●When there is a rut or hole in the sur-face of the road
●When driving on a metal cover (grat-ing), such as those used for drainage
ditches
●When driving up or down a steep
slope
●If a sensor is hit by a large amount of
water, such as when driving on a flooded road
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is coated with a sheet of spray or heavy rain
●When driving in inclement weather such as fog, snow or a sandstorm
●When strong winds are blowing
●When vehicle horns, vehicle detec-tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of
other vehicles or other devices which produce ultrasonic waves are near the vehicle
●If the front of the vehicle is raised or lowered due to the carried load
●If the orientation of a sensor has been changed due to a collision or other
impact
●The vehicle is approaching a tall or
curved curb
●Driving close to columns (H-shaped
steel beams, etc.) in multi-story park- ing garages, construction sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the vehicle has been in an accident or is malfunctioning
●On an extremely bumpy road, on an incline, on gravel, or on grass
●When a tire chains, compact spare tire or an emergency tire puncture repair
kit is used
■Detection range of the sensors
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)

cles and similar stationary objects*
●Small motorcycles, bicycles, pedestri-
ans, etc.*
●Vehicles moving away from your vehi- cle
●Vehicles approaching from the park-
ing spaces next to your vehicle*
●The distance between the sensor and approaching vehicle gets too close*: Depending on the conditions, detec-
tion of a vehicle and/or object may
occur.
■Conditions under which the system may not function correctly
The RCTA function may not detect vehi-
cles correctly in the following situations:
●When the sensor is misaligned due to
a strong impact to the sensor or its surrounding area
●When mud, snow, ice, a sticker, etc., is covering the sensor or surrounding area on the position above the rear
bumper
