STARTING AND OPERATING 261 cause damage to the transmission. The torque converter will refill within five seconds of shifting from Park into any other gear position. Rocking the Vehicle If the vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the gear selector rhythmically between D (Drive) and R (Reverse), while applying slight pressure to the accelerator. NOTE: The Electronic Stability Program (ESP) and Traction Control (if equipped) should be turned OFF before attempting to rock the vehicle. Refer to "Electronic Brake Control System" in Section 3 of this manual. The least amount of accelerator pedal pressure to maintain the rocking motion without spinning the wheels or racing the engine is most effective. Racing the engine or spinning the wheels, due to the frustration of not freeing the vehicle, may lead to transmission overheating and failure. Allow the engine to idle with the transmission 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. 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. 5
