I had to take a nap in my car recently and wanted to find the best settings which will reserve the most energy while I sleep. I already have a driver profile called "Sleep", which moves the chair rearward to create more legroom. It also flattens the back and tilt the steering wheel up a bit. That's all driver profile can do, but I didn't stop there. Here's what I also did: - Disable both gadgets in the dashboard. - Folded side-mirrors. - Locked the car. - Change heated seat to max level. - Lowered the brightness of the 17" display, then put it in cleaning mode. I'm not sure what's the best settings for A/C. I just set the fan speed to 2 and everything else Auto. Is there anything else could be done?
