If you calculate your average fuel
economy by dividing liters of fuel
used by 100 kilometers traveled
(miles traveled by gallons used),
your figure may be different than displayed for the following reasons:
• your vehicle was not perfectly level during fill-up
• differences in the automatic shut-off points on the fuel pumps at
service stations
• rounding of the displayed values to the nearest 0.1 liter (gallon)
Checking your highway fuel economy using the electronic
message center display
Use the following procedure will allow you to accurately monitor your
actual highway fuel economy. This procedure requires the vehicle speed
control system to be set to highway speeds and must be run only on
suitable roadways where long distance speed control can be safely
maintained.
You may notice gradual improvement in fuel economy over the course of
your vehicle’s break-in period (approximately 1 600 kilometers [1 000
miles]).
1. Set the speed control. Refer to Speed control in the Controls and
features chapter.
