Driving AUTOMATIC TRANSMISSION OPERATION Understanding the gearshift positions of the 4-speed automatic transmission Your vehicle has been designed to improve fuel economy by reducing fuel usage during coasting or deceleration. When you take your foot off the accelerator pedal and the vehicle begins to slow down the torque converter clutch locks up and aggressively shuts off fuel flow to the engine while decelerating. This fuel economy benefit may be perceived as a light to medium braking sensation when removing your foot from the accelerator pedal. Your vehicle's automatic transmission is equipped with a special shift strategy that ensures maximum heater performance during cold weather operation. When ambient temperature is 23°F (-5°C) or below and the engine coolant temperature is below 100°F (38°C), light throttle upshifts may be slightly delayed. Once the engine coolant temperature reaches 160°F (71°C) the normal shift strategy will resume. This is normal operation and will not affect the function or the durability of the transmission. If the normal shift strategy does not resume once the engine coolant temperature reaches the normal operating temperature, or if the downshifts and other throttle conditions do not function normally, see your authorized dealer as soon as possible. P (Park) This position locks the transmission and prevents the rear wheels from turning.
