INTELLIGENT PARKING ASSIST SYSTEM GENERAL


  1. OUTLINE


    1. The intelligent parking assist system shows a rear view of the vehicle on the navigation display. In addition, it controls the steering to assist the driver with perpendicular parking and parallel parking.

    2. With the power source on (IG), if the driver moves the shift lever to reverse and the IPA/parking assist monitor select switch indicator is black, the parking assist monitor system is activated. If the IPA/parking assist monitor select switch indicator is yellow, press the IPA/parking assist monitor select switch to turn the indicator black, and the parking assist monitor system can be activated. If the vehicle is about to be parked without activating the parking assist monitor system when the IPA/parking assist monitor select switch is yellow, the intelligent parking assist system is automatically activated.

    3. The system calculates the target parking position based on signals from ultrasonic sensors mounted on both sides of the front bumper, and reduces the driver's burden of adjusting the target parking position on the display, thus improving ease of use.

    4. This system is equipped with a self-diagnosis, which is operated on a dedicated window that appears on the display panel, just as in the navigation system.

  2. PRECAUTION


    1. General Handling Precautions


      1. Do not rely entirely on the parking assist. When backing up, drive the vehicle as carefully as you would drive one that is not equipped with the parking assist.

      2. Back up slowly by pressing the brake pedal to adjust the speed.

      3. If the vehicle appears about to come into contact with an adjacent vehicle or pedestrian, press the brake pedal to bring the vehicle to a stop. Then, cancel the parking assist by pressing the stop switch on the screen.

      4. When the system is operating in the parking assist mode, the steering wheel will turn automatically. Maintain a proper driving posture without allowing a necktie, pendant, or your arms to get caught, or long finger nails to come in contact with the steering wheel. Do not allow children to come close to the steering wheel.

      5. Never attempt to back up the vehicle only by observing the screen. If you do so, you could unexpectedly crash the vehicle or cause an accident because the image on the screen could differ from the actual situation. While backing up, also make sure to use the inside and outside rear view mirrors in order to directly verify the safety of the rear and surrounding areas.

      6. Do not expose the rear television camera assembly to a strong impact or force, as it will alter the orientation of the camera and cause improper operation. Because the adjustment of the orientation of the camera requires special tools, make sure to have it performed at a dealer.

      7. Operate the system only with the back door completely closed.

      8. Do not operate the system on a slippery surface such as a frozen or snowy road, or when using tire chains. Doing so could unexpectedly cause the vehicle to crash or become involved in an accident.

    2. Road Condition Precautions


      1. Depending on the number of occupants, the load conditions, the slope of the road, and bumps in the road, a disparity may occur between the display indication and the actual distance on the road surface. Operate the vehicle carefully.

      2. If a steep uphill incline is behind the vehicle, an obstacle appears to be further away than it actually is, as shown in the illustration below.

    3. Precautions for 3-Dimentional Obstacles


      1. Drive carefully when any 3-dimentional objects such as walls or vehicles are placed behind the vehicle as the distance and estimated guide lines are provided based on the road surface.


        • When passing close to a 3-dimentional object, the vehicle may come into contact with the object even if the estimated vehicle path seems not to be in contact with it on the screen.

        • The distance indication varies between 3-dimentional objects such as a vehicle and plane objects such as the road surface on the screen. As shown in the below illustrations, points A and B are actually horizontally in the same position and point C is a bit away from them, however, the points are displayed in order of distance from the vehicle, B, C and A. Therefore, the vehicle comes into contact with the 3-dimentional object if backed to the point B on the screen.

        • On slippery roads such as snowy roads, disparity may occur between the estimated vehicle path and actual vehicle path.

        • When only one parking line is provided, the vehicle may seem to be parallel to the line on the screen even if they are not actually parallel.

    4. Ultrasonic Sensor Precautions


      1. Under the following conditions, the ultrasonic sensor may not function properly:


        • A sensor is covered with foreign matter, such as mud or snow (detection function returns to normal when sensor is cleaned).

        • A sensor is frozen (detection function returns to normal when the temperature of the sensor rises).

        • A hand or similar obstacle is blocking the sensor.

        Tech Tips


        • In very cold weather, the malfunction display may appear and the sensors may not be able to detect obstacles.

        • If the malfunction display appears, visually check the sensors first. If the sensors are free of foreign matter but the malfunction display remains, a sensor may have a malfunction.

      2. The detection range may be affected by the following conditions:


        • A ultrasonic sensor is covered with foreign matter, such as mud or snow.

        • The vehicle is in an excessively hot or excessively cold area.

      3. Under the following conditions, a detection error may occur:


        • Driving on a bumpy road, an unpaved road, or in tall grass.

        • 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.

        • It is raining heavily or the sensor is splashed with water.

        • The vehicle is tilted at a steep angle.

        • The vehicle is equipped with a fender pole or a wireless antenna mechanism.

        • A sensor is covered with foreign matter, such as mud or snow.

        • The vehicle is moving forward or backward towards high curbs or objects that are perpendicular to the ground.

        • A sensor is sprayed with high-pressure water or steam.

        • A towing hitch is mounted on the vehicle.

      4. The sensors cannot detect the following objects:


        • Thin objects, such as wires and ropes.

        • Materials that absorb ultrasonic waves, such as cotton, snow, etc.

        • Objects with sharp edges.

        • Short objects.

        • Objects that are tall and protrude toward the vehicle above the detection range of the sensors.

      5. Other notices:


        • The sensors cannot detect objects directly under the bumper. (A sensor may detect low objects and thin poles, and then lose track of them.)

        • Beware 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 visually confirm the safety of your surroundings when driving or parking.

        • The sensors may not be able to detect obstacles that are too close to the sensor.

        • The sensors may not be able to detect obstacles if the sensors have been dropped or subjected to a strong impact.

    5. Other Precautions


      1. Do not use tires except those that came new with the vehicle, otherwise the system may not operate properly. If the tires are replaced, an error could be created in the positions at which the flame appears on the screen. Therefore, consult dealer before replacing the tires.

      2. Directly verify the rear and the surroundings of the vehicle for safety with your eyes before backing up the vehicle. Never attempt to back up the vehicle only by observing the screen.

      3. The range of the image that the rear television camera assembly can capture is limited. It does not capture objects in the vicinity of both corners of the bumper or below them. The clearance distance that appears on the screen is different from the actual distance because the rear television camera assembly uses a wide-angle lens.

      4. It is normal for the screen to appear indistinctly under the following conditions: the sunlight or headlight directly enters the lens, the area is dark (at night), or the temperature near the lens is high or low.

      5. The camera is unable to capture a clear image if the glass in front of the lens is dirty. Therefore, clean the glass if it has water drops, snow, or dirt on it.

      6. If a bright light (for example, sunlight reflected off the vehicle body) is picked up by the rear television camera assembly, the smear effect, peculiar to the CCD camera.
