OFF-ROAD CAPABILITIES ALL-WHEEL DRIVE OPERATION Single-Speed Operating Instructions/Precautions This system contains a single-speed (HI range only) transfer case, which provides convenient full-time all-wheel drive. No driver interaction is required. The Brake Traction Control (BTC) System, which combines standard ABS and Traction Control, provides resistance to any wheel that is slipping to allow additional torque transfer to wheels with traction. NOTE: This system is not appropriate for conditions where AWD LOW range is recommended. Refer to "Off-Road Driving Tips" in "Starting and Operating" on the DVD for further information. Electronically Shifted Transfer Case (Three-Position Switch) This electronic shift transfer case and is operated by the AWD Control Switch (Transfer Case Switch), which is located on the center console. This electronically shifted transfer case provides three mode positions: • All-wheel drive automatic range (AWD AUTO) • All-wheel drive low range (LOW RANGE) • Neutral (NEUTRAL) When additional traction is required, the LOW RANGE position can be used to lock the front and rear driveshafts together forcing the front and rear wheels to rotate at the same speed. The LOW RANGE position are designed for loose, slippery road surfaces only. Driving in the LOW RANGE positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components. AWD Control Switch When operating your vehicle in LOW RANGE, the engine speed is approximately three times that of the AWD HI position at a given road speed. Take care not to overspeed the engine and do not exceed 25 mph (40 km/h). NOTE: The "SERV AWD Warning Light" monitors the electronic shift all-wheel drive system. If this light remains on after engine start up or illuminates during driving, it means that the all-wheel drive system is not functioning properly and that service is required. 152
