Hi,

My S/S button has lit up yellow and the triangle light has appeared on my dash.

I've been advised to disconnect my battery overnight... I have no idea how!

Help please?

Thanks in advance.

all you need to do is unclamp the negative terminal post,
( metal clamp bolted onto battery terminal.)

it's a good idea to use a plastic cap / tube as an insulator
