On the 21/06/22 I had a flat battery {under Bonnet}, called RACQ to assist which they did. Upon reversing the vehicle out of my garage I noticed that the yellow lines on the reversing camera screen had disappeared. I tried resetting through the 3 modes of reversing options but could not rectify the problem, I looked in the Manual but could not find anything on the Reversing Camera. Please anyone if you can offer or advise of a fix as I find it difficult to reverse without these yellow guiding lines that move with the steering of this vehicle. I have spoken with Toyota Australia who are investigating? Thank you Stephen
