1 Single trip memory
The memory accumulates and stores information about distance driven and fuel used from the time the ignition was switched on until the time it was switched off. If the ignition stays off for 2 hours or more, stored information is automatically deleted. If the trip is continued within 2 hours after the ignition was switched off, the new values are added.
2 Total trip memory
The memory displays and stores the accumulated driving and fuel consumption data of any number of single trips up to a total driving time of 99 hours and 59 minutes, and up to a total distance of 9,999 miles (9,999 km). If one of the maximum values is exceeded, then the memory is automatically cleared and starts again from 0.
Possible MFI menu displays
The following displays can be accessed in the MFI menu if enabled under Settings > MFI data. Displays that are not enabled will not appear.
Display Function
Travel time Driving time in hours (h) and minutes (min) corresponding to trip memories 1 and 2 (toggle).
Consumption --.- mpg Current fuel consumption in miles per gallon (l/100 km) while driving. When units are set to miles, dashes appear instead of a number when the engine is running and the vehicle is standing still. When units are set to kilometers, the display shows liters consumed per hour when the engine is running and the vehicle is standing still. Consumption --.- l/100 km
Av. consumption --.- mpg Average fuel consumption in miles per gallon (l/100 km) on trips per trip memories 1 and 2 (toggle) is displayed once the vehicle has been driven about 330 feet (100 m). Until then, dashes appear instead of a number. The value displayed is updated every 5 seconds. Av. consumption --.- l/100 km
Range -- mi Estimated distance in miles (km) that the vehicle can go with the fuel left in the tank the way you are currently driving. Takes account of the current fuel consumption, among other things. Range -- km
Route -- mi Distance driven in miles (km) per trip memories 1 and 2 (toggle).
Route -- km
Average speed -- mph Average speed on trips per trip memories 1 and 2 (toggle). Displayed once the vehicle has been driven about 300 feet (100 m). Until then, dashes may appear instead of a number. The value displayed is updated every 5 seconds. Average speed -- km/h
-- mph Digital display of the current vehicle speed.
-- km/h
Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical than constantly accelerating and braking. Usually you can reach your destination just as quickly by driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the air conditioner has to produce starkly contrasting temperatures, it requires a large amount of energy, which is generated by the engine. The temperature in the vehicle should therefore not be extremely different from that of the outside temperature. It may be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
x Towing a trailer.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not running. The transmission will not be lubricated and will be damaged.
