9.17.7.1. Steering Assist cancel
Under the following conditions, the Steering Assist cancels, and the Steering Assist status indicator and the Steering Assist indicator turn off:
When unusual lane markers appear in the travelling lane or when the lane marker cannot be correctly detected for some time due to certain conditions (for example, a snow rut, the reflection of light on a rainy day, the presence of several unclear lane markers).
When the windscreen wiper operates in the high (HI) speed operation (the Steering Assist is disabled when the wiper operates for more than approximately 10 seconds).
Action to take:
Turn the ICC system off using the <CANCEL> switch. When the conditions listed above are no longer present, turn the ICC system on again using the Steering Assist button or the steering wheel mounted controls.
