Picture this: You’re cruising along the open road, enjoying your drive when suddenly, a warning light grabs your attention. It’s the TPMS (Tire Pressure Monitoring System) indicator, shining brightly on your dashboard. What does this mean, and what should you do next? In this guide, we’ll unravel the mysteries behind the TPMS indicator light and guide you on how to address it.

What Is The TPMS Light?

To kick things off, let’s acquaint ourselves with TPMS. The Tire Pressure Monitoring System (TPMS) is a vital safety feature in cars. Its main job? To keep a vigilant eye on your tire air pressure and give you a heads-up if it detects low pressure – a potential safety risk.

Why Does TPMS Matter?

Safety First: 

Maintaining the correct tire pressure is crucial for safety. Properly inflated tires offer better grip and control, especially in less-than-ideal driving conditions.

Saving Money: 

Well-inflated tires also mean improved fuel efficiency. Under-inflated tires increase resistance, leading to more trips to the gas station and higher expenses.

Longer Tire Life: 

Even tire wear, thanks to the right tire pressure, extends the life of your tires – a win for your wallet.


Under-inflated tires indirectly contribute to higher carbon emissions by reducing fuel efficiency – something we’re all working to reduce.

What Does The TPMS Light Mean?

When the TPMS indicator light comes on, it’s alerting you to a potential tire pressure issue. This signal can mean one of the following:

Low Tire Pressure: 

The most common reason behind the TPMS light is low tire pressure. It might be due to a slow leak, temperature changes, or natural pressure loss over time.

Tire Puncture: 

A sharp object on the road may have caused a puncture in your tire, resulting in pressure loss and the TPMS alert.

False Alarms: 

Sometimes, the TPMS sensor itself is acting up. It could be sending false warnings or inaccurate pressure readings.

Low Sensor Battery: 

Some TPMS sensors have their own batteries, which need replacement every few years. If these batteries die, the system will alert you by blinking. It is very important to pay attention to these warnings. 

How Does Cold Weather Affect My Tire Pressure?

Before we dive into what to do when your TPMS light comes on, let’s talk about how cold weather affects tire pressure:

Temperature Drop: 

When it gets colder, your tire pressure can drop too. Cold weather causes the air inside your tires to contract, leading to lower pressure. This pressure drop can trigger the TPMS warning light.

Regular Checks: 

To keep your tires in top shape, especially during cold weather, make it a habit to check your tire pressure regularly. Most vehicles provide recommended pressure ranges for various conditions in the owner’s manual or on the driver’s side door frame.

What Do I Do When My TPMS Light Comes On?

Now, here’s the game plan when your TPMS light illuminates:

Inspect Your Tires: 

First, find a safe spot to pull over and visually inspect your tires. Use a trusty tire pressure gauge to check the air pressure in each tire, including the spare.

Add Air: 

If you discover that one or more tires are significantly under-inflated, it’s time to play mechanic. Inflate them until they reach the recommended pressure levels, typically found in your vehicle’s owner’s manual or on a sticker inside the driver’s side door frame.

Check for Damage: 

While you’re inspecting, keep an eye out for any visible signs of damage, like nails or screws embedded in your tire’s tread. If you spot any harm, schedule a professional repair or replacement.

Reset TPMS: 

After inflating or addressing any tire issues, you may need to reset the TPMS system. Consult your owner’s manual for precise instructions, as the process can vary from one vehicle to another.

Seek Professional Help: 

If the TPMS light persists, even after checking and adjusting the tire pressure, it’s time to consult the experts. Visit our service center, and we can diagnose any underlying issues, such as finicky sensors or system malfunctions.

The TPMS indicator light may be a small part of your dashboard, but its contribution to safety is invaluable. When it lights up, it’s your cue to investigate and take action promptly. Ignoring it could lead to trouble, from safety risks to decreased fuel efficiency and premature tire wear. By understanding the TPMS light’s signals and responding effectively, you’ll keep your vehicle and tires in great shape, ensuring a safer and more efficient journey on the road.

What Does It Mean If My TPMS Light Is Blinking?

A blinking TPMS light often indicates a more serious issue, such as a faulty sensor or a system malfunction. In this case, it’s crucial to get professional help immediately to ensure your safety on the road.

Now You Know Everything You Need To Know About Your TPMS Light!

Your TPMS (Tire Pressure Monitoring System) light is like a silent guardian, always ready to alert you to potential tire pressure issues that can affect your safety, wallet, and the environment. Understanding the importance of maintaining proper tire pressure and being able to decipher the TPMS code is key to ensuring a smooth and secure journey on the road.

Remember, when the TPMS light comes on, don’t ignore it! Take proactive steps to check your tire pressure, inflate if necessary, inspect for damage, and reset the TPMS system as needed. And if that light continues to shine or blinks, don’t hesitate to seek professional assistance to address any underlying problems.

By staying vigilant and responsive to your TPMS, you’re not only protecting yourself and your passengers but also contributing to fuel efficiency and the longevity of your tires. So, the next time your TPMS light illuminates, consider it your vehicle’s way of saying, “Let’s keep rolling safely!”
