We had an incident involving our new GLC. We’ve realised that the car stays in active mode due to several Situations which is to be expected. It will flash a warning but it is not displayed consistently so you’d not see it unless sitting there with you’re eyes glued open.
We came to the realisation that by locking the car and hearing the horn tone for locked we could ensure the car was “off” and be assured of an easy start in the morning !
Think like a German engineer to understand your GLC and all will be well.
