Why There Is A Yellow Exclamation Point On Dash?

Modern vehicles are complex machines. This complexity means that there is a lot to go wrong with a car, and when things do, your first indication is often a warning light on the dashboard. The yellow exclamation point on dash depicts the tire pressure warning light. This warning light signifies that one of the vehicle’s tires is underinflated or the tire has low pressure.

In this article, we’ll be discussing this warning light in detail. Let’s get started.

Reasons Behind A Yellow Exclamation Point On Dash?

The tire pressure monitoring system (or TPMS) is responsible for activating this light. If it turns on while you’re driving, you should pull over and stop as soon as possible. Driving with a flat or underinflated tire is unsafe, as it can drastically alter the vehicle’s handling.

Common reasons for this light to turn on include a puncture, a faulty tire pressure sensor, as well as seasonal temperature changes, which can cause a tire to lose pressure gradually.

Low tire pressure happens naturally over time from driving. Cold weather also causes low air pressure as the air compresses inside of your tires. Driving with low tire pressure can cause poor fuel economy, present risks to your tires and rims, and impact your vehicle handling.

Can You Drive With The Tire Pressure Monitoring System (TPMS) Warning Light On?

No, it is very unsafe to continue driving when your TPMS lights are on. If you continue to drive with your tires having issues, this could cause a blowout that could be dangerous to you and other people present on the road. It is highly recommended that you head for the nearest gas station if there is a yellow exclamation point on dash.

How Do Tire Pressure Monitoring Systems (TPMS) Work?

The TPMS uses a sensor that is mounted on the car’s wheel, and this sensor measures the air pressure located in each of the car’s tires. When your car’s air pressure drops 25% below its recommended level, and if one or more of the tires are low on air, the sensor activates and relays this information to your vehicle’s computer system. This lights up the yellow exclamation point on dash.

How Do I Turn The Yellow Exclamation Mark On Dashboard Light Off?

The yellow exclamation mark warning light appears when your car’s tires are underinflated. The driver should immediately head for a gas station or a rest stop with an air pump. The tires on the car should get inflated to the car’s recommended PSI. Tires usually lose pressure because of a small puncture or leak or a sudden decrease in the temperature.

If your tire is punctured, you should go to a nearby service center and get it replaced. If you have a bit for miles to drive, use your spare tire to replace the punctured one. Doing these can save you the hassle of experiencing a flat tire while driving on the road.
