The car can be in different states of "on". Some of these states do not turn on the LDC. The most annoying mode is the one where radio, lights and fans are on, but LDC and heatpump are off. This is a mode often inadvertently on while quick-charging - it quickly drains the 12 Volt battery, so after recharging, you may experience turning the car off, and afterwards the car will not turn on.
