TikTok user @megansbubble revealed the handy “A” button that sits in the car console.

Megan said: “If you have a button in your car that looks like this, it’s your automatic start-stop button.

“It will automatically turn off your vehicle if it’s stationary for an extended period of time, like when you’re at a traffic light or perhaps driving through the Starbucks thoroughfare.

“It is intended to increase fuel consumption and reduce emissions.”

Although stop-start technology has been around in cars for decades, it didn’t really take off until around 2008.

A start-stop or stop-start system automatically turns off and restarts your car’s internal combustion engine.

The idea is to reduce the time your engine spends idling.

Stop-start should also result in a reduction in your fuel consumption and vehicle emissions.

This is especially helpful for vehicles that spend a lot of time stationary in heavy traffic.

According to research by the American Automobile Association, stop-start technology resulted in a 5% to 7% improvement in fuel economy.

This saving might seem small, but it would certainly add up over the life of your car.

A study by the Polytechnic University of Madrid measured the CO2 emissions of two four-wheel drive vehicles.

A reduction of more than 20% was recorded for the car equipped with the start-stop system.
