Are you seeing that little, yet alarming, yellow light with the exclamation mark popping up on your dash? If you’re a new driver, this light may come as a shock. You may be wondering what triggered it and how urgent this particular situation could be.
As the name suggests, your tire pressure monitoring system (TPMS) light coming on typically means your tire pressure is low. However, sometimes it turns on due to a drastic drop or rise in temperature. So, when do you know to act urgently? If your light turns on merely because of a temperature change, your light will turn off within one day. If your light stays on, it could be due to a tire puncture causing a slow leak of air.

Your TPMS helps you to avoid potentially unsafe situations by monitoring the air pressure in your tires and alerting you when one of them drops by 25 percent or more below its recommended pressure. Your dashboard will display either the official TPMS symbol or a graphic indicating which tire is in need of air. It can be tough to tell if the air in a tire is too low or too high just by looking at it. When you see this light, bring your vehicle into Pep Boys for a tire pressure check.

If your TPMS light comes on and continues to stay on, at least one of your tires has a low pressure level. If your car does not have the feature that shows which tire is low, make sure you check the pressure of all of your tires. You can do this by visiting a local garage or with a gauge.



Keep in mind that fluctuating temperatures may be causing your TPMS light to turn on and off. In fact, for every 10 degrees, your tires will either drop or increase by 1 psi. Once you begin driving around, your light might turn off due to the rising temperature and/or heat generated from your vehicle. However, even if you’re light goes off, you should still use a gauge to check your tire pressure. If your TPMS light continues to go on and off, there’s a chance that one or more of your tires is below the optimal air pressure threshold.



If the light flashes for over a minute every time you start your car and then remains illuminated, this means your TPMS isn’t functioning properly and you should take it to an automotive service center for an inspection. Until repaired, continue to check the air pressure of all of your tires with a gauge, and add air to the tires that need it.
Maintaining proper tire inflation is essential to vehicle handling, gas conservation, overall tire performance and load-carrying capability. A properly inflated tire will reduce tread movement, rolling resistance and increase water dispersion. There are many things that can come into play and affect tire pressure including temperature changes, tire punctures or other damage. Your TPMS acts as a safeguard, alerting you to waning tire pressure and helping you to avoid unsafe situations. Pep Boys offers TPMS services designed to keep your TPMS working properly.
