Kia Sedona: Non-operational conditions of rear parking assist system

The rear parking assist system may not operate properly when :

1. Moisture is frozen to the sensor. (It will operate normally when the moisture has been cleared.)

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.)

3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradient).

4. Objects generating excessive noise (vehicle horns, loud motorcycle engines, or truck air brakes) are within range of the sensor.

5. Heavy rain or water spray exists.

6. Wireless transmitters or mobile phones are within range of the sensor.

7. The sensor is covered with snow.

8. Trailer towing

The detecting range may decrease when :

1. The sensor is stained with foreign matter such as snow or water. (The sensing range will return to normal when removed.)

2. Outside air temperature is extremely hot or cold.

The following objects may not be recognized by the sensor :

1. Sharp or slim objects such as ropes, chains or small poles.

2. Objects which tend to absorb the sensor frequency such as clothes, spongy material or snow.

3. Undetectable objects smaller than 1 m (40 in.) in height and narrower than 14 cm (6 in.) in diameter.
