When did Mazda fit SCBS?

[SteveAWD]

Hi. I'm going to fit a tow bar to my 2013 2.2 sport nav CX5.
I've also purchased a Masda dedicated wiring kit C851-V3-921A.
I've read that to make this work for the caravan electrics, if the car has SCBS I will need a "split charge" relay fitted as well but I don't know when SCBS became current on the CX5.
Does anyone know the answer to this question. Many thanks.

The CX-5 achieved a solid five stars in the Euro NCAP crash tests (2012). Features include stability control, traction control, automatic city braking and curtain airbags.
