The Driver Information Center (DIC) buttons are located to the right of the steering wheel on the instrument panel, near the air outlets.

INFO (Information): Pressing this button up or down will display the OUTSIDE TEMP, MILES RANGE, MPG AVG, MPG INST, GAL FUEL USED, AVG MPH, TIMER, BATTERY VOLTS, LF-RF-LR-RR TIRE (If Equipped), ENGINE OIL LIFE, TRANS FLUID LIFE, PHONE (Option) and FEATURE PROGRAMMING and Blank Display.

INFO (Information) RESET: Pressing this button will reset the MPG AVG, GAL FUEL USED, AVG MPH, TIMER, ENGINE OIL LIFE and TRANS FLUID LIFE. For more information about the trip odometer, see Speedometer and Odometer .

    • MPG AVG (Average Miles per Gallon): This message shows the approximate fuel economy you have averaged since the last time you reset the value. To reset the MPG AVG (Average Fuel Economy), press the INFO button to display the MPG AVG then press and hold the INFO RESET button until 0.0 MPG AVG is displayed.
    • GAL (Gallons) FUEL USED: This message shows how much fuel has been used since the last reset. To learn how much fuel is used from a new starting point, press the RESET button while the GAL FUEL USED is displayed in the DIC.
    • AVG MPH (Average Miles per Hour): This message shows the average speed you have traveled at since the last time you reset the value. To reset the value, press the INFO button to display AVG MPH then press and hold the INFO RESET button until 0.0 AVG MPH is displayed.
    • TIMER: This feature is like a stopwatch, in that you can clock the time it takes to get from one point to another.
        To operate, press the INFO button to display TIMER. Each of the fields for the hours, minutes and seconds are two numeric digits.
        Once TIMER 00:00:00 is displayed, press the ON/OFF button to start the timing feature. Press the ON/OFF button again to stop it. If you will be starting and stopping your vehicle, during a trip for instance, the TIMER feature will automatically start timing where it left off when you last stopped. To reset it, press and hold the INFO RESET button until the display reads TIMER 00:00:00. Press the INFO button to exit from the TIMER display.
    • ENGINE OIL LIFE: Press the INFO button to display ENGINE OIL LIFE, then press and hold the INFO RESET button until 100% ENGINE OIL LIFE is displayed. (This only needs to be reset after you have had the oil changed.)
    • TRANSMISSION FLUID LIFE MONITOR: Under normal conditions, the rate of deterioration of the transmission fluid is slow. See Scheduled Maintenance for proper fluid and change intervals. To reset the transmission fluid life, press the INFO button to display TRANS FLUID LIFE, then press and hold the INFO RESET button until 100% TRANS FLUID LIFE is displayed. (This only needs to be reset after you have had the fluid changed.)
ON/OFF: Pressing this button turns the Personalization Features on and off. (FEATURE PROGRAMMING must be displayed on the DIC to begin actual programming.) This button also starts and stops the timer.

OUTSIDE TEMP (Temperature): This message shows the outside temperature. After this display has been on the DIC for about five seconds, the words OUTSIDE TEMP will disappear so that only the temperature remains.

MILES RANGE: This message shows about how many miles you can drive without refilling your fuel tank. Once the range drops below 40 miles (64 km) remaining, the display will show LOW.

MPG INST (Instantaneous Miles per Gallon): This message shows the instantaneous fuel economy which varies with your driving conditions, such as acceleration, braking and the grade of the road being traveled. The INFO RESET button does not function in this mode.

BATTERY VOLTS: This message shows the current battery voltage. If the voltage is normal the display will show BATTERY VOLTS OK. If the voltage drops below 10.5 volts, the display will show BATTERY VOLTS LOW. If the voltage is above 16 volts, the display will show BATTERY VOLTS HIGH. If the display shows the high or low message, you will need to have your battery checked. See DIC Warnings and Messages for more information.

LF-RF-LR-RR TIRE (If Equipped): On vehicles equipped with the tire pressure monitor, this message shows the tire pressure for each tire (left front, right front, left rear and right rear). Pressing the INFO button will scroll through the tire pressure for each of the four tires, such as the following:

    • 34 PSI LF TIRE OK or
    • 234 kPa LF TIRE OK

If a tire pressure is below 25 PSI (172 kPa) or above 38 PSI (265 kPa), the message will appear as shown above except it will show TIRE LOW or TIRE HIGH as appropriate. If desired, the tire pressure information can be programmed not to appear when using the INFO button to scroll through the DIC displays. See DIC Vehicle Personalization .

If a low or high tire pressure is detected by the system while driving, a CHECK TIRE PRESSURE message will appear in the display. If this occurs, press the INFO button to scroll to the tire(s) with a low or high pressure condition. See DIC Warnings and Messages for more information.

ENG/MET (English/Metric): Press this button to display information in the English (miles) or metric (kilometers) system.
