You know, it should show a "low voltage warning" light (CEL) on the cluster, but I didn´t find it in my user manual

I just want to add a final tip that you probably know, but if your battery is kind of old, you should avoid rapid discharge, for example, keeping the radio on with the ignition off. That's because the battery cannot hold the charge like a new one; it loses efficiency.
