The air, like most other substances, expands when heated and contracts when cooled. So when the weather gets colder, the tire pressure decreases, which could trigger TPMS warning light in i10. The tire pressure will vary with temperature by about 1 psi (7 kPa) for every 12°F (6.5°C)...
with a low light level triggering an augmentation to the visual indicator, such as through an LED blinking at night. Thus the visual indicator provides a system that is highly visible at night or day and that keeps power consumption at reduced levels. In other embodiments, test modes may be...
