* 1: The value changes according to load of power steering motor.

* 2: This is in close agreement with a motor speed command value. Although a quick steering operation may cause disagreement, this is not a malfunction.

* 3: Usually, 100% is displayed. An excessive steering operation gradually lowers the percentage. When left standing, the percentage returns to 100%.

* 4: This may not agree with the speedometer indication immediately after the ignition switch is turned ON. This is not a malfunction.
