2. PRECAUTIONS FOR INTUITIVE PARKING ASSIST SYSTEM
(a) Under the following conditions, the detection function may not function properly:
(1) A sensor is covered with foreign matter, such as mud or snow (detection function returns to normal when the sensor is cleaned).
(2) A sensor is frozen (detection function returns to normal when the temperature of the sensor rises).
(3) A hand is blocking a sensor.
HINT:
- In very cold weather where a malfunction display appears, the sensor may not be able to detect obstacles.
- If the malfunction display appears, visually check the sensor first. If the sensor is free of foreign matter but the malfunction display remains, the sensor may have a malfunction.
(b) The detection range may be affected by the following conditions:
(1) A sensor is covered with foreign matter, such as mud or snow.
(2) The vehicle is in an excessively hot or excessively cold area.
(c) Under the following conditions, a detection error may occur:
(1) Driving on a bumpy road, an unpaved road or in tall grass.
(2) Ultrasonic waves are received from the horn or parking sonar system of another vehicle, a motorcycle engine, or the air brakes of a large vehicle.
(3) It is raining heavily or the sensor is splashed with water.
(4) The vehicle is tilted at a steep angle.
(5) The vehicle is equipped with a fender pole or a wireless antenna mechanism.
(6) A sensor is covered with foreign matter, such as mud or snow.
(7) The vehicle is moving forward or backward towards high curbs or objects that are perpendicular to the ground.
(8) A sensor is sprayed with high pressure water or steam.
(9) A towing hitch is mounted on the vehicle.
(d) The sensors cannot detect the following objects:
(1) Thin objects, such as wires and ropes
(2) Materials that absorb ultrasonic waves, such as cotton, snow, etc.
(3) Objects with sharp edges
(4) Short objects
(5) Objects that are tall and protrude toward the vehicle above the detection range of the sensors
(e) Other notices:
(1) The sensors cannot detect objects directly under the bumper. (A sensor may detect low objects and thin poles, and then lose track of them.)
(2) Be aware that the detection range of this system is limited. In certain conditions, some objects may not be detected. As a result, always make sure to check all around the vehicle when driving or parking.
(3) The sensors may not be able to detect obstacles that are too close to the sensor.
(4) The sensors may not be able to detect obstacles if the sensors have been dropped or subjected to a strong impact.
