Hi all,

In need of some help please.

On my second L405 now and this morning I noticed that every time I got down to a 'low speed' or stopped the car i.e. at a roundabout/junction the picture of the car chassis with wheels (like terrain response) kept popping up in the information display between the rev counter and speedometer. If I turned the steering wheel it shows you the wheels turning etc then as you speed up it goes out. All settings are normal on the car and I've not pressed anything by mistake and I've never seen it do this before. The only thing different this morning were that because it was 0 degrees I put the park heater on before I left the house. Bit frustrating as I've never seen it do this before but it looks like an off-road/terrain response type of thing but I've been into all settings and everything is how it should be. Could it have been because the temperature outside was low and the auto terrain response kicks in. Not sure..,.....

Any ideas???

Thanks

I never had this at low temperatures... got get your car to the dealer - that is def. not ok.  All my spelling errorz are belong to me!

That is not normal behaviour. To get that display, you should have the auto terrain function set to a manual setting and not be on a road setting.

Have you looked in the manual to see if there is anything about such behaviour. I can imagine that if slippery the auto terrain response does something but don't understand that is it only at low speed, I mean I would expect it more at higher speed. Also I'd expect a warning about temperature/slipperiness even before the terrain response started to do something........... MY 2010 5.0 SC Galway green and sand interior!!

The auto-terrain will put the car in "Grass/Snow" mode once (I think) the cold weather warning light comes on (at +3C, I believe). There isn't any indication that it has done that, other than the car being sluggish (nothing on the info display).
The only way you find this out is to turn off auto-terrain. As the knob rises, you can see briefly on the dashboard that it switches from "Grass/Snow" to "General".

If you leave the knob in the off (raised position) then it doesn't do that. In cold snaps, I leave it off.

Doesn't sound right. Mine does not have reduced performance and we have had minus temperatures a lot recently. Try using the 4x4 info screen in the main display to see what decisions the auto terrain is making. 2019 D5 HSE Lux SDV6 Indus
