Parking Assist Sensors

Am new to the Tacoma family and need a little help. I have a 2021 SR5 V6 Crew Cab and have noticed I don't get any sensors going off when I get close to something either front or back. I also noticed I don't have a "P" button to enable or disable the system. I do have the sensors in place tho'. Is there something else that controls these sensors that I may be missing?

Thanks very much.

 

SR5 likely doesnt have it, and its not something you can add.

Check your bumpers for small circles like these.

 

I'll be darned. I do have lane departure sensors but it doesn't appear as tho' I have the front and rear parking sensors as I thought. 2 days old, and have a lot to learn about it. Still a nice truck! : )
Thanks very much for the quick response.
