Service Information
The customers initial perception of vehicle fuel economy, based upon the information displayed on the Driver Information Center (DIC), may contribute
to poor ratings for fuel economy in various automotive surveys. The way the vehicle is handled during the build and shipping process may leave
inaccurate values in the history of the DIC. During the pre-delivery inspection, the dealership must reset the "average fuel economy" setting.
Reset the average fuel economy setting according to the information in the appropriate Owners Manual. Once reset, the average fuel economy will then
be calculated starting from that point.
The data used to determine fuel range is an average of recent driving conditions. This setting cannot be reset. However, as the customers driving
conditions change, the data will be gradually updated to reflect more accurate readings.
If a customer inquires about fuel economy, and the fuel consumption information is not on the price sticker, do not exaggerate the vehicle's capabilities.
In either case, stress that fuel economy performance is highly dependent upon driving habits and vehicle usage.
