Hm! I'll have to make it clearer. You have to go to the garage during the day. It's next to the port, with the bright orange bikes.
The dialogue was actually quite clear where you're supposed to go. It was mostly my mistake, I went back and found that I had missed the left arrow that takes you from Life Support to the garage, possibly because it's quite close to the arrow that returns you to the Lida/Paris/Hunter living quarters.
