I also have to revise my previous comment on DRL. I tested mine with ignition on but engine off and saw DRL stayed on with turn signal. However, I noted yesterday that whilst driving the DRL does indeed turn off when the turn signal is on. So different behavior depending on whether engine is running or not and car is in motion. I also note the DRL turn off when car is put in park, so transmission setting also matters.
I recall reading there are specific laws dictating exterior light settings in the US which will impact how they behave (this is why, for example, the animated turn signal setting is not available in the US as they don't meet the federal requirements). This probably affects the DRL settings as well.
THis is absolutely stupid and I hope it isn't true! I've seen reviews of the velar showing the the turn signal blinking orange with the white DRL still on, which makes sense. I can't stand cars that only blink orange, it looks like they have a burnt out light. The newer grand cherokee's in the USA fixed this problem, and blink orange and alternate with the DRL still staying ON! SO there is no law that this can't be this way in the usa. I'm in the USA and grand cherokee's do it. It's more confusing for other drivers with the DRL turning off as they want to tell you a light is burnt out and distracts them.
We need to find a friend at the dealer to change these things or buy the program to adjust these settings ourself. You can do this for the Mercedes S class if you have a laptop, and about $700.
