Warning all gone
Adjustment of the steering angle was successful.
Visually align the steering wheel in horizontal position to check the zero position of the steering angle (wheels in straight ahead position)
With the steering wheel in horizontal position,Does the displayed steering angle=0 degrees
Adjustment of the steering angle was carried out correctly.
Initialise run flat indicator if necessary
