It is normal for your tire pressure warning light to come on after you inflate your tires. This is because your car stores the data regarding correct tire pressure. Once you inflate the tires, the light may remain illuminated momentarily.
To turn the light off, you can press and hold the "TPMS" button until the light turns off. It may also turn off after driving the vehicle for a short period.
If the tire pressure warning light does not turn off after driving for 10 minutes, or if it comes on again after you have turned it off, you should have your tires checked by a qualified mechanic to ensure they are properly inflated.
