No audible beep from rear sensors when backing

I just bought a 2021 Silverado 2500HD. When I'm backing and get close to objects I get a caution symbol that flashes up on the screen but no audible beeping. I looked in the manual and it says in the settings under collision/detection system the following may appear:

Alert Type

Forward Collision system

Lane Change Alert

Park Assist

Rear camera park assist symbols

Rear cross traffic alert.

 

The manual goes on to say that alert type sets the alert from either beeps or safety alert seat. When I go into my menu under collision/detection system I dont have options for Alert Type or Forward Collision system but i have the other options lane change alert and so on.

 

Am I to assume that because I don't have alert type in my settings menu I have no audible warning? Seems odd that it would have a rear backup detection system that shows visual warning symbols on the screen but no audible beeps. Even my 2019 work truck beeps when I get close to something while backing up. If I don't have the audible warning is there a way to add it?

Did you figure anything out?

My '21 only had the seat vibrate as far as I can remember.  I missed the audible beep but don't think there was a way to change it.  Still better than my '22, has all the sensors and button but still missing the module to make it work 😉.

      On 2021 3500hd it consistently sets automatically when selecting park if the incline/decline is above a certain angle.

      Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

      By Policeoff01 · Posted

      Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
