Driver Info Screen Problem

Something else I just noticed which provides some clarification and, regrettably, some confusion.

Distance Recognition Support System (DRSS), which will operate independently of radar cruise, varies following distances based on vehicle speed for each setting. See pages 4-141 and 4-142 of the 2020 manual. It shows variable following distance examples for 25 mph vs. 50 mph for each setting. If there was any doubt at this point that radar cruise does the same thing this should all but clinch the matter. Good for one should be good for the other.

Further, it appears radar cruise piggybacks on DRSS. Compare the distances shown on those section 4 pages for the first 4 DRSS settings at 50 mph to the radar cruise chart. They are the same..

Now for the confusion.

That section 4 chart indicates there are 4 DRSS settings from near to far. The vehicle itself only has 3 settings. If there is a Batman out there, riddle me how the manual can show an additional DRSS setting. Even page 9-11 of the manual which shows the DRSS personalization settings shows just the three.

I have a 2020 CX-5 Signature and somehow this is new information to me. Please elaborate so I can learn the location of this switch ...

I don't know how long you've had your 2020 CX-5, but I guess I'll be the guy that says the obvious....read the manual.

I wonder if it has to do with time rather than actual distance. The old 2 second rule, or whatever it is.

At 50mph, it's X distance. At 70mph is X+Y distance to equal roughly same time space to vehicle in front.

Just a thought.

It's all part of the vehicular space-time continuum's rich pageant.

If you know the speed and the braking distance of the vehicle at that speed you can get to the time to stop. Conversely, I don't know how you could get to the time to stop independently of the other two factors. So you go with the two measurables. Of course time to stop can vary by exogenous variables like road conditions and tire type or wear, so there has to be some Kentucky windage involved. Or something like that I guess.

Does the speed of a slower vehicle in front factor into the slowing process instead of a stopping scenario? Dunno. And frankly this is all intellectual curiosity for me but you never know when something practical might come to light.

I'm sorry to report than if it was not cold and rainy I'd be golfing today. My apologies.

I made an error in post #23 which I've now corrected. There are in fact 4 DRSS trailing distance settings illustrated in Section 4 of the manual, not 5. The 5th. entry in the table is a warning, not a setting. The four DRSS settings for trailing distance in fact mirror the radar cruise settings indicating that radar cruise piggybacks on DRSS and, again, that those distances are speed variable.

The question remains as to how Section 4 can illustrate 4 DRSS settings when the vehicle has only 3 and Section 9 shows only 3 user settings. Reading the manual does not always provide clarity when getting into the weeds.

Not quite sure but I think that indicates that radar cruise is on but not set to a specific speed.
Does your car have a HUD?

No HUD.
