290 STARTING AND OPERATING selector in N (Neutral) for at least one minute after every five rocking-motion cycles. This will minimize overheating and reduce the risk of transmission failure during prolonged efforts to free a stuck vehicle. FOUR-WHEEL DRIVE OPERATION Quadra-Trac Iா Operating Instructions/Precautions - If Equipped The Quadra-Trac I௡ is a single speed (HI range only) transfer case which provides convenient full-time 4-wheel drive. No driver interaction is required. This transfer case divides engine torque almost evenly with 48 percent of engine torque to the front axle and 52 percent of engine torque to the rear axle. The Brake Traction Control System (BTC), 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: The Quadra-Trac I௡ system is not appropriate for conditions where LOW range is recommended. Refer to "Off-Road Driving Tips" in this section. CAUTION! When "rocking" a stuck vehicle by moving between "First" and R (Reverse), do not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.
