Features of your vehicle
The detecting range may decrease
when:
Non-operational conditions of
rear parking assist system
Rear parking assist system pre-
cautions
1. The sensor is stained with foreign mat-
ter such as snow or water. (The sens-
ing range will return to normal when
removed.)
The rear parking assist system may
not operate properly when:
• The rear parking assist system may
not sound sequentially depending on
the speed and shapes of the objects
detected.
1. Moisture is frozen to the sensor. (It will
operate normally when the moisture
has been cleared.)
2. Outside air temperature is extremely
hot or cold.
• The rear parking assist system may
malfunction if the vehicle bumper
height or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
2. The sensor is covered with foreign
matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally when the material is removed
or the sensor is no longer blocked.)
The following objects may not be rec-
ognized by the sensor:
1. Sharp or slim objects such as ropes,
chains or small poles.
3. Driving on uneven road surfaces
(unpaved roads, gravel, bumps, gradi-
ent).
2. Objects which tend to absorb the sen-
sor frequency such as clothes, spongy
material or snow.
• The sensor may not recognize objects
less than 30 cm (11.8 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
4. Objects generating excessive noise
(vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
3. Undetectable objects smaller than 1 m
(40 in.) and narrower than 14 cm (6 in.)
in diameter.
• When the sensor is frozen or stained
with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile
phones are within range of the sensor.
7. Trailer towing.
• Do not push, scratch or strike the sen-
sor. Sensor damage could occur.
