  2. CLEARANCE WARNING BUZZER


    1. Depending on the detection distance and the detection area, the sound pattern of the clearance warning buzzer will vary.

      Detection Area Detection Distance cm (in.) Buzzer Sound Pattern ON/ OFF Time (msec.)
      Front Corner Long 60 +/- 6 to 45 +/- 5 (23.6 +/- 2.4 to 17.7 +/- 2.0) 200 / 200
      Middle 45 +/- 5 to 35 +/- 4 (17.7 +/- 2.0 to 13.8 +/- 1.6) 100 / 100
      Short 35 +/- 4 or less (13.8 +/- 1.6 or less) Continuous Sound / 0
      Front Corner Longest 100 +/- 10 to 60 +/- 6 (39.4 +/- 3.9 to 23.6 +/- 2.4) 500 / 200
      Long 60 +/- 6 to 45 +/- 5 (23.6 +/- 2.4 to 17.7 +/- 2.0) 200 / 200
      Middle 45 +/- 5 to 35 +/- 4 (17.7 +/- 2.0 to 13.8 +/- 1.6) 100 / 100

      Rear Center Longest 150 +/- 15 to 80 +/- 8 (59.1 +/- 5.9 to 31.5 +/- 3.1) 500 / 200
      Long 80 +/- 8 to 65 +/- 7 (31.5 +/- 3.1 to 25.6 +/- 2.8) 200 / 200
      Middle 65 +/- 7 to 50 +/- 5 (25.6 +/- 2.8 to 19.7 +/- 2.0) 100 / 100
      Short 50 +/- 5 or less (19.7 +/- 2.0 or less) Continuous Sound / 0

  3. MULTI-INFORMATION DISPLAY


    1. The location of an obstacle and the approximate distance between the vehicle and the obstacle are displayed on the multi-information display.

    2. The number of lines shown on the display changes based on the actual distance and flashes when the distance is short.

      *a Yellow *b Red
      *c Flashes *d Long
      *e Middle *f Short
      *g Longest - -

    3. Screens displaying warning messages relating to an ultrasonic sensor malfunction, ultrasonic sensor freezing, or presence of foreign matter on the ultrasonic sensor are displayed on the multi-information display.

      *A All sensor icons illuminate regardless of which sensor detected the malfunction, freezing or dirt. - -
      *a Malfunction Warning *b Frozen/Dirty Warning

  4. ACCESSORY METER


    1. The displays of the clearance sonar icon and the warning message have been partially changed.

    2. If an obstacle is detected when the multi-terrain monitor system is activated, the approximate distance between the vehicle and the obstacle is displayed on the accessory meter assembly.

    3. The distance is displayed by color based on the actual distance to the obstacle. When an obstacle is detected at the long or middle distance, the indicator is yellow. The color changes from yellow to red when the distance becomes short.
