Apologies Guys ,Even though you knew what I meant ,I should have said " AUTO HOLD " As Brake assist is ,the system
that helps with the speed of braking according to pedal speed on the brakes .
Mine didn't work ,as didn't someone else on here ,so I checked the Bible
.
As in a few functions they only work on the last Ignition on cycle ,provided the driver door is closed ,seat belt on ,
and engine is running . So say you have ditched your seat belt to reverse ,or are moving the car on the drive ,
check the system light is on or It has disabled ,because of one of the aforementioned reasons .
Worth mentioning the Auto Engine Off as well ,there is 14 reasons why that may not work ,check the Bible
