Roll Stability Control system
It may not have it due to differences in the hybrid vs. gas engine design, and to different weight distribution because of the batteries in the hybrid.
This vehicle was made as cheaply as possible due to the cost of the hybrid system (borrowed from Toyota). I have issues with noise and the lack of a few normal features normally found on Mercury vehicles. The cheap radio antenna for one as well as other plastic parts on the interior of the car. I change the horn from single tone to dual tone and upgraded the headlight bulbs to higher power, whiter color. Good luck.
