2007 Dodge Ram 1500 Pickup Owner's Manual - Page 349

STARTING AND OPERATING 349 HSA on Automatic Vehicles The system will work in reverse and all forward gears on vehicles equipped with an automatic transmission. The system will not activate if the vehicle is placed in neutral. HSA on Manual Vehicles The system will work in reverse, forward gears, and neutral on manual transmission equipped vehicles. The system does not recognize neutral on manual vehicles, thus it will hold the vehicle on an incline for a short period while in neutral, regardless of clutch position. To prevent this, do not attempt to roll down a hill simply by putting the transmission in neutral and letting gravity act on the vehicle, as the HSA will prevent the vehicle from rolling. Instead, use the appropriate gear for moving in the desired direction. Towing and Hauling with HSA (Vehicles Equipped with Automatic Transmissions Only) The HSA system does not know if your vehicle is loaded or towing a trailer, unless the "TOW/HAUL" button, located on the transmission gear selector lever, is selected. When activated, the "TOW/HAUL" light will illuminate in the instrument cluster. Refer to the "Starting and Operating" Section of this manual for more information on the "TOW/HAUL" mode. In order to accommodate the extra weight entailed under towing and hauling conditions and to increase driver comfort while launching on a hill, the system recognizes when the Tow/Haul button is activated and compensates by releasing brake pressure at a slower rate while throttle is applied to in order to prevent the vehicle from rolling down the hill. 5
