1. Read the manual. You can turn off the eco light in the dash settings.
2. It's an extremely slow vehicle. You simply have to live with it.
3. Hasn't been an issue for me.
I paid $37K for my Trail w/KDSS, all weather mats, and crossbars in Denver. I'm surprised dealers are discounting these as much as they are. 4Runners and Tacomas are flying off the lots here.
