Rearview camera Opel Mokka

Hello guys, my father got his new Opel Mokka 1.4 l Turbo with intelli-link and rear-view camera just before Christmas. Now we have found that the rear-view camera built by Opel does not show any guidance lines for the distance assessment or the controlled lane. I know this so far from all models of different manufacturers only so that these guidance lines are available. The Opel dealer also didn’t know about these guidance lines. Is that right? Is Opel the only manufacturer without these guide lines. Apart from that, the Mokka is a very nice and practical compact SUV! Thank you in advance.
