Need Help to Identify Fault (W204)

[jh79]

I've been experiencing random faults whenever I drive my car (C180 W204) at low gear. Alarms such as release handbrakes, inactive airbags etc (See attached).

It only happens when I start the engine and move off, normally at carparks. 

Anyone encounter similar issues.

I found that when my car battery was weak the electronics of the car went wonky. Example: autolight will not be switched on even during heavy rain, car cannot recognise my key for keyless go. All these "faults" went away after I changed my main battery that was 2.5 years old.

Weak batteries can potentially cause a myriad of errors... Worth checking your battery when too many systems fail at the same time. Rarely do our cars' systems break down all at the same time.
