I have a brand new 718 GTS 4.0 - under 200 miles on it. It doesn't have adaptive cruise control or blind spot detection or lane change assist or any of the radar-based doodads, only Park Assist.
Sometimes, when I corner hard or change lanes aggressively, I get a fairly loud, fast, three beeps from somewhere. There are no warning lights or any other indicators.
Sometimes there are cars nearby, sometimes not. They way I drive, I get these beeps several times a day.

Does anyone have any idea what this is? And how to turn it off?

May be low brake fluid during hard corning ? Wild guess

elt38

Thanks for the suggestion @lowbee . However, I'm not braking during the cornering maneuver (I've done it with and without braking before the turn), and the manual says I should have a BRAKE warning on the instrument panel if the brake fluid is low, too hot, or braking force is uneven. I'm thinking it's something else.

Do you have a dash cam?
External GPS Nav?

winter tire speed warning?

elt38

Why yes, @worf928 I do have a dashcam. So you think this is the "triple acoustic signal" the (very poor) dashcam manual mentions?
I pulled the MicroSD card, and according to the manual there should be an entry in the "Events" folder whenever such an event is logged. There is no Events folder, but there is a Driving folder that just logs everything all the time.
As for the Dashcam app, I'm having the same $&@#* problems connecting that every other dashcam owner seems to have, so I can't check the app's version of events, or adjust the sensitivity.
Sigh.

There's a tire speed warning @reacp911 ? You learn something new every day. Thanks for the idea.
But I'm not cornering at higher speeds than I travel on the flat and straight: in fact, it's the high g low speed corners that do it the most. Also, the manual claims the winter tire speed warning is an instrument panel display, not an audible warning.
I did check that I have the right tire type and wheel diameter set, because that could surely throw you off.

I installed a BlackVue dash cam system in my wife’s DD 991S and left the “crash (event) detection” sensitivity at default. It detects an “event” about every 10 minutes on average (WAG.). “Events” are typically a pothole, bad patch (patches are usually worse than the pothole they fix ‘round here) and other lumpy pavement. The default cam settings don’t live in the same world as sport car suspensions.

Unplug your cam’s power, drive your route and see what’s what.

Sorry and not sure but it sounds like the beeps are a warning for the bad roads potholes and/or bad fixes in the USA. After 40 years in the USA (MAS & CA) and only the last couple of years in AZ with surprising excellent roads. We retired in the South of Spain, all good roads like the rest of the EU, we drive a 718 Spyder manual (better driving experience than my 991 PDK) hard cornering, hard braking, hard on myself LOL, but never irritating beeps.

I just got three beeps from a pothole, so I suspect you're right. But it's not just rough roads, it's also abrupt lateral g force.
I used to live in Europe, and my European visitors never fail to marvel at the (bad) state of US roads. The roads here are one reason why I didn't buy a Taycan: it's so much heavier, and has trouble maintaining traction on uneven surfaces.

I have had 18" Winter selected in my TPMS and never got a warning at 140+ MPH

TXshaggy

IIRC, it is a user defined Limit 1/2 and doesn't have anything to do with the TPMS selections.

OP, there are several warnings that also have audible tones. Perhaps you provide some more detailed metrics on when it is triggered.

We are in RI and I can say unequivocally that RI roads are the worst anywhere. When you cross from RI to CT,it is like night and day. CT roads much better. Not sure about MA.

I drove pretty aggressively at an autocross and never heard any beeps. This is interesting.

Waiting to hear official answer.

I visited the Providence area one time to pick up a dog. I agree their roads are crap.
