Unlike the short-term memory, the long-term
memory is not erased automatically. You can se­
lect the time period for evaluat ing trip informa­
tion yourself.
F or some vehicle functions, you can access driv­
ing information from the short-term memory
consecutively in the line ©~
page 23, fig. 5 by
turning the thumbwheel @.
Fuel consumption
The cu rrent fue l consumption can be shown us­
ing a bar graph¢
fig. 8. The average consump­
tion stored in the short-term memory is also dis­
p layed. If the bar is green, your vehicle is saving
fuel through one of the following functions:
- Recuperation : electrical energy can be stored in
the battery when the vehicle is coasting or driv­
ing downh ill. The bar will move toward 0.
-Cylinder on demand system*: the engine auto­
matically switches four cylinders
(4.0L TFS!) or
six cylinders (6.3L FSI) off when lower power
output is required and other conditions are met . This change is not noticeable to the pas­
sengers. The cylinders will switch on again
when higher power output is needed.
