When the outside temperature drops significantly, the tire pressure could decrease and activate the low tire pressure warning lamp.
The warning lamp could also illuminate when you use a spare wheel, or tire sealant from the inflator kit.
Regularly checking the vehicle tire pressures can reduce the possibility for the warning lamp to illuminate due to outside air temperature changes.
After you inflate the tires to the recommended pressure it could take up to two minutes of driving over
20 mph (32 km/h) for the warning indicator to turn off.
