“It’s supposed to increase fuel economy and reduce emissions.”
Although start-stop technology on cars has been around for decades, it didn’t really kick off until around 2008.
Most new cars now come with it and more and more models had it fitted over the past 14 years.
Not everybody likes their engine stopping and starting all the time, but it will save you fuel and therefore money over the months and years.
There’s also a myth that it does damage to your start motor and engine – cars with start-stop tech have been engineered to cope with it.
The car’s electronic brain will work out when it can and can’t be used based on lots of different factors including the engine’s temperature.
The button is likely to have an A within a circle, but if you’re struggling to find it, check your car’s manual or ask a dealer.
