When the direction indicators are used, Pilot Assist steering assistance is temporarily disengaged. When the direction indicator is switched off, steering assistance is reactivated automatically if the lane's edge markings can still be detected.
If Pilot Assist is unable to interpret the lane clearly, e.g. if the camera or radar unit is unable to see the side markings for the lane, Pilot Assist temporarily disables steering assistance – speed and distance regulation functions remain active. Steering assistance is resumed when the lane can be interpreted again. In these situations, slight vibration in the steering wheel may alert the driver to the fact that steering assistance has been deactivated temporarily.
