The parking sensors may not function correctly in these
situations:
One or more of the ultrasonic sensors or cameras is
damaged, dirty, or obstructed (such as by mud, ice,
or snow, or by a vehicle bra, excessive paint, or
adhesive products such as wraps, stickers, rubber
coating, etc.).
It is important to understand your vehicle's original tire
sizes and pressures, and the GVWR (Gross Vehicle
Weight Rating) and GAWR (Gross Axle Weight Rating).
This information can be found on two labels attached to Model Y.
Both labels are visible on the door pillar when the front door is open.
