2012 jeep liberty review this car review is specific to this model, not the actual vehicle for sale. Standard equipment includes sirius satellite radio, electronic stability control, anti-lock brakes with brake assist, all-speed traction control, and electronic roll mitigation. The jet edition trim features 20-inch polished wheels, chrome body side moldings, blacked-out headlamps and unique 'jet' badging. The skyslider option is a full-length open canvas sunroof that can slide accordion-style forward, backward or partially opened to any position in-between. A multimedia infotainment system with 30-gigabyte hard drive and navigation system is available. For 2012, the renegade trim has been discontinued and the jet edition package (first offered in the 2011 model year) is now a trim. Anti-lock Brakes✔ Sunroof/Moonroof✔ Navigation System
