I have a rental car with interesting problem. It is a Renault Clio made in 2017. On the dash there is only a digital display showing speed, there is no dial. The problem is the display brightness is very dim if the headlights are turned on. If I switch the lights off the display gets brighter. The result is that I cannot see the speed at all because of the sunlight.
Is there any way to set the display brighter?
