At least in theory, our Hyundai Tucson will never be left with the 12-volt battery drained, because when the Tucson detects that the battery is running low, it will automatically disconnect it to prevent it from completely discharging. In this case, we will need to enter the vehicle with the security key, and press the battery reset button, and within 15 seconds start the vehicle: we will have 30 minutes to recharge the 12-volt battery using the engine.

If we are unable to restart the vehicle within 15 seconds after pressing the reset button, the system will be disconnected again and we can try again. If it still does not work on the second attempt, we should consult the owner's manual in section 8; if the electrical accessories do not work properly after the resets, consult the owner's manual in section 5.
