I think it's better to use "poor-man's DRL" than get the DRL option. The DRL option cannot be turned off, even when it's impolite to have the headlights on. And as you discovered, it doesn't turn the taillights on. Perhaps you would also prefer to just leave the light switch in the on position. The lights turn off when you turn off the car and open the driver's door, then turn back on next time you start the car. I believe this works even if you have the DRL option.
If you plan to leave the car undriven for over a week, be sure to turn off the light switch. The switch drains the battery slowly when in the on position even though the lights are off.
