DRIVERS are only just realising what a hidden button in their car boot does - and it makes life so much easier.
People were amazed to discover a little-known feature in popular Mercedes-Benz motors that saves a lot of time.
In a helpful video shared by expert Matthew Watson on TikTok, the whizz revealed this button is located on the inside of the boot door.
After giving it a press a tow, or trailer hitch, appears automatically from underneath the rear of the car.
Motorists in the comment section outlined this handy hack can also be found on certain Land Rovers and BMWs.
But, one impressed viewer wrote: "Honestly to me BMWs is no match to Mercedes."
"Mercedes is always the best, everything is just perfect," agreed another.
Meanwhile a third added: "My X3 had it too, just not in such a handy place."
It comes as drivers were stunned to find another secret button that could save their life on the road.
Motorists are aware their rear-view mirror keeps them safe - but on a sunny day, glare reflecting off the glass could actually put them at risk.
Being temporarily blinded by the light for even a second could cause a serious accident.
Or, if a car travelling behind you at night had their headlights on full beam it could be a major distraction.
Content creator, Coach B, showed her followers how to prevent a potential accident with a little-known hack.

An expert has revealed one vital motor part that should be changed regularly - and it's not what you might expect.
Plus, another unseen bonus feature that could prevent costly accidents.
