Thanks! Much appreciated.There's a tire mobility kit under your trunk floor, or at least there should be one.
It contains a Slime canister that you may need in order to temporarily patch a tire if you have a small puncture.
There's an expiration date printed on it. You need to replace the canister with a new one periodically.
The car has no idea what that expiration date is, but it offers a timer to help remind you.
You didn't configure the timer so you're seeing the default warning. You can check your tire kit and reset the timer appropriately through the center touchscreen.
All of this info is in your manual:
