4-30 Instruments and Controls Range This display shows the approximate number of remaining miles (mi) or kilometers (km) the vehicle can be driven without refueling. The message "Range" displays if less than 31 mi (50 km) can be driven with the fuel remaining in the tank. The message "Refuel!" displays when approximately 19 mi (30 km) can be driven with the fuel remaining in the tank. With less than 19 mi (30 km) worth of fuel remaining the range display will show "- -" once the "Refuel!" message has been acknowledged. See DIC Warnings and Messages (Base and Uplevel Systems) on page 4-37 for information on acknowledging the message. The fuel range estimate is based on an average of the vehicle's fuel economy over recent driving history and the amount of fuel remaining in the fuel tank. This estimate will change if driving conditions change. For example, if driving in traffic and making frequent stops, this display may read one number, but if the vehicle is driven on a freeway, the number may change even though the same amount of fuel is in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. Fuel range cannot be reset. Stop Watch This display can be used as a timer. To start or stop the timer, press the right arrow on the audio system. To reset the timer, press the left arrow until the value returns to zero. If your vehicle has the left thumbwheel on the steering wheel, you can start or stop the timer by pressing the thumbwheel. Average Speed This display shows the average speed of the vehicle in miles per hour (mph) or kilometers per hour (km/h). This average is calculated based on the various vehicle speeds recorded since the last reset of this value. The measurement can be reset to zero at any time and restarted. See "Reset" later in this section. Distance Travelled This display shows the current distance traveled in either miles (mi) or kilometers (km) since the last reset. The measurement can be reset to zero at any time and restarted. See "Reset" later in this section.
