The motoring group told Express.co.uk: “Many car models have a hidden feature built within the key fob that is unknown to most drivers.
“Standing outside your vehicle, hold down the unlock button on your car keys and the windows will start to unwind.
“Some cars may differ – so try holding down the unlock button once, releasing it, and then pressing down again to activate this remote feature.”
This vital tip could help drivers as temperatures start to rise over the spring and summer as it could help cool a vehicle before stepping inside.
On colder days, opening a window before driving off could help defog steamed-up windscreens.
Experts at motor retailer Dick Lovett said: “Holding the unlock button down opens the windows on your car (or roof, on convertibles), whilst holding down the lock button closes them.
“This is ideal during warmer months to avoid getting straight into a hot car. This trick works on many different models and is not limited to one manufacturer.
“All you’ll need to do is hold down the unlock button on the key fob, and your car windows will begin to roll down whilst you stand outside the vehicle.
“For some cars, you may be required to hold down the unlock button once, release, and then hold it down again before it will work.”
However, motorists must ensure they don’t accidentally hold down their key fob buttons when they are not intending to.
Leaving a car window open unattended could have drastic consequences and risk vehicles becoming targeted by thieves.
Jake Fisher, senior director of auto testing at Consumer Reports, has previously warned: “These features can be fantastic if the owner understands the sequence of key-fob button pushes to access them, but they can also be frustrating or even harmful if these features are triggered accidentally.”
