Collision Warning

Collision Warning
I was driving this evening after dusk down an empty 2 lane road and I got "Collision Warning" triangle in the dial where the speedo is. My car is an MT but I felt the engine cut off power and it jerked a tiny bit.
Any idea what can cause this? Bugs maybe? My car doesn't have that hemispherical dome under the bumper like I've seen on some cars so I assumed I didn't have any fancy radar/forward collision mitigation.

Mine does not have ACC or LKA either and also a MT C4S. I do not think we have collision warning on these, I thought it only came with ACC or LKA (having the front camera). Does yours have LKA?

I believe that you'll still get the collision warning without PAS, but the car will only hit the brakes on its own if it is ACC/PAS is equipped.
The warning precedes any intervention by the system. Without PAS, I don't think that it cuts engine power. It's possible that you might have been startled by the warning and lifted off just a little bit.
I have triggered the warning going at a high rate of speed on a backroad, heading into a 90 degree lefthander featuring a giant, billboard-style, left arrow. At the time, I actually told the car "calm down, I've got this".
Edit: Note, my own car is ACC/LKA equipped.

I have this in my Cayenne and it’ll freak you out, because it triggers much sooner than is necessary IMHO and has no place in a sports car of this level. You’re correct it’s part of PAS - standard equipment...

“Porsche Active Safe (PAS – Warning assistant and BrakeAssist) can in certain dangerous situations initiate measures to protect occupants and other road users.
Porsche Active Safe has the following functions1):
There is a way to adjust the warning and response thresholds of the PAS, and if I recall correctly, turn it off completely through the PCM. I’ll have a look when I next have time and note down the menu steps and post them here.
Porsche Active Safe has the following functions1):
- Distance warning (depending on equipment)

How to turn off Porsche Active Safe:
From The “Settings” menu:
Select “Assistance system settings”
then, “Porsche Active Safe”
then “Collision Warning”
From here you can select the desired warning threshold;
“Early”
”Regular”
”Late”
or “Off”
I’ve found “Late” to give almost zero false alarms. Only very rarely does it give me the pre-warning chime, which is usually about the same time my foot is already applying the necessary braking.
*Edit to add that I suspect this may only turn off the warning chime and brake pulse feature. It’s possible that the final, last moment break application still remains active.

Thanks, useful information. I can’t turn it off in my Mercedes.
