Engine Oil Life System The engine oil life system calculates engine oil life based on vehicle use and displays a DIC message when it is necessary to change the engine oil and filter. The oil life system should be reset to 100% only following an oil change. Driving for Better Fuel Economy Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible... Avoid fast starts and accelerate smoothly. Brake gradually and avoid abrupt stops. Avoid idling the engine for long periods of time. When road and weather conditions are appropriate, use cruise control, if equipped. Always follow posted speed limits or drive more slowly when conditions require. Keep vehicle tires properly inflated. Combine several trips into a single trip. Replace the vehicle's tires with the same TPC Spec number molded into the tire's sidewall near the size. Follow recommended scheduled maintenance. Resetting the Oil Life System 1. Turn the ignition to ON/RUN, with the engine off. 2. Press the DIC INFO button until OIL LIFE REMAINING displays. 3. Press and hold the DIC INFO RESET button until 100% displays. 4. Turn the key to LOCK/OFF. See Engine Oil Life System on page 6‑19. . ... . 1-23
