132 UNDERSTANDING THE FEATURES OF YOUR VEHICLE Average Fuel Economy (AVG ECO) Shows the average fuel economy since the last reset. This display mode becomes less sensitive to instantaneous changes in fuel consumption as the number of total vehicle miles since the last reset increases. It is suggested that this mode be reset periodically for general operation or when driving conditions change significantly (for example, at the end of a trip or when a trailer is connected or disconnected). Distance To Empty (DTE) Shows the estimated distance that can be travelled with the fuel remaining in the tank. The estimated distance is determined by a weighted average of the instantaneous and average fuel economy, according to the current fuel tank level. When Distance To Empty = 0, the fuel gauge pointer will initially be on the red "E" marker. At this point (fuel gauge pointer on the red "E" marker) there is reserve fuel capacity, which corresponds to approximately 8% of tank volume. This reserve capacity was put in place to prevent the likelihood of customers running out of fuel when operating at maximum load conditions in areas where there aren't many gas stations. NOTE: The Distance To Empty will remain equal to zero, until the vehicle runs out of fuel or is refueled.
