I went to read the manual - online version using my browser on my PC - and the page that would cover this comes up BLANK. I wonder if they took it down because it is not correct for recent and new 2022 Model Y, as has been discussed here.
Still there, on page 20:
USB Ports
Model Y has two USB ports located in the front
compartment of the center console. These ports can be
used to:
• Connect and charge USB devices.
• Play audio files stored on a phone or USB device (see
Playing Media from Devices on page 137).
• Save videos when using features such as Sentry
Mode or Dashcam (see Dashcam and Sentry Mode on
page 144).
NOTE: If your Model Y is equipped with a USB port
located in the glove box (described below), it is
recommended that you use the glovebox USB to save
Sentry Mode or Dashcam videos because power
consumption is minimized and the location is more
secure.
Both ports are USB-C compatible.
Open the front compartment of the center console. The
front USB ports are located on the rear wall of the
compartment.
Two additional USB ports are located in the rear of the
center console (on vehicles manufactured since
approximately June 2020, these ports are USB-C). These
ports charge USB-connected devices but do not
communicate with the vehicle.
