2008 Jeep Liberty Owner's Manual - Page 320

320 STARTING AND OPERATING • For vehicles equipped with an automatic transmission, the HSA will work in reverse gear and all forward gears. The system will not activate if the transmission is in "P" (Park). • For vehicles equipped with a manual transmission, the HSA will work in reverse gear, neutral, and all forward gears. WARNING! There may be situations where the HSA (Hill Start Assist) will not activate and slight rolling may occur, such as on minor hills (i.e., less than 7%), or with a loaded vehicle, or while pulling a trailer. HSA is not a substitute for active driving involvement. It is always the driver's responsibility to be attentive to distance to other vehicles, people, and objects, and most importantly brake operation to ensure safe operation of the vehicle under all road conditions. Your complete attention is always required while driving to maintain safe control of your vehicle. Failure to follow these warnings can result in an accident or serious personal injury. Towing with HSA HSA will provide assistance during acceleration on an incline while towing a trailer.
