390 STARTING AND OPERATING The system will only work if the intended direction of the vehicle and vehicle gear match. For example, if the intended direction is forward up a hill and the vehicle is in DRIVE and the activation criteria are met, HSA will activate. The system will work in REVERSE and all forward gears, and will not activate if the vehicle is placed in NEUTRAL. Towing and Hauling with HSA The HSA system does not know if your vehicle is loaded or towing a trailer unless the TOW/HAUL switch, located on the center stack, is selected. When activated, the "TOW/HAUL Indicator Light" will illuminate in the instrument cluster. Refer to ЉAutomatic Transmission" in "Starting and Operating" for further information. 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 switch is activated and compensates by releasing brake pressure at a slower rate while throttle is applied in order to prevent the vehicle from rolling down the hill. WARNING! • If you use a trailer brake controller with your trailer, your trailer brakes may be activated and deactivated with the brake switch. If so, when the brake pedal is released, there may not be enough brake pressure to hold the vehicle and trailer on a hill and this could cause a collision with another vehicle or object behind you. In order to avoid rolling down the incline while resuming acceleration, manually activate the trailer brake or apply more vehicle brake pressure prior to releasing the brake pedal. Always remember the driver is responsible for braking the vehicle. (Continued)
