INST ECONOMY (Instant Economy): Instant fuel economy reflects the fuel economy that the vehicle has right now. Instant fuel economy varies with your driving conditions, such as acceleration, braking and the grade of the road being traveled. Unlike average fuel economy, instant fuel economy cannot be reset. FUEL RANGE: The fuel range is an estimated distance that your vehicle can travel on the remaining fuel. The fuel economy used to calculate the range is based on your driving history since the last reset of the average speed. FUEL USED: The fuel used display will show you how much fuel has been used since the last time it was reset. To reset the fuel used to zero, press and hold the SET button while the fuel used is displayed on the DIC and until the display goes to zero. AVG SPEED (Average Speed): The average speed display will show your average speed from when you first started your vehicle. To reset the average speed, press and hold the SET button while the average speed is displayed on the DIC and until the speed resets to your current speed. OIL LIFE LEFT HOLD SET TO RESET: This message displays the current percentage of the oil life by the engine oil life system. Be careful not to reset this display other than when the oil has been changed. See "How to Reset the Engine Oil Life System" under Engine Oil Life System on page 368 for more information. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance on page 475 and Engine Oil on page 365. 237
