Motorists have been to told to check if their car has an SOS button as many are unaware of the potentially lifesaving technology.
All new cars and vans have to include the emergency call system known as eCall, where there is an SOS button fitted, as part of legislation brought in four years ago.
When airbags are triggered, vehicle sensors activate the eCall system, which automatically sends its location to a 999 operator, reported Manchester Evening News.
