The single journey memory processes the infor­
mation on
a
journey from the time the ignition is
switched on until it is switched off. If the journey
is resumed within two hours after the ignition is
switched off, the new figures are automatically
included in the calculation.
Unlike the
single
journey memory, the totaljour-
ney memory is not erased automatically. In this
way, you can determine the period for which you
wish the on-board computer to supply driving in­

formation.

Fuel consumption
The current fuel consumption can be shown in a
bar display
^>Fig.
15. The average fuel consump­
tion from the single journey memory can also be

displayed.
If the barturns green, yourvehicle is
saving fuel using the following function:
- Recuperation: Electrical energy can be stored in
the battery (recuperation) if the vehicle is trav­
elling downhill or coasting in gear (overrun). In
this case, the bar will move towards the
Q

symbol.

- Active Cylinder Management*: The engine au­
tomatically shuts down two cylinders when per­
formance demand is low and certain other
con­

ditions have been met. This process is imper­
ceptible to the occupants. The driver message

2-cylinder
mode will appear if the average fuel
consumption display
^>Fig.
15 is selected in the
instrument cluster. The cylinders are reactiva­
ted under heavier load conditions.
Energy consumers*
In the Energy consumers view, auxiliary equip­
ment currently affecting the vehicle's fuel
con­

sumption is listed. The display shows up to
three energy consumers. The energy consumer
drawing the most power appears at the top of
the list. If more than three energy consumers are
switched on, the ones currently using the most
power are displayed. In addition, a scale
indi­

cates the overall current fuel consumption of all
energy consumers.
Economy tips
Applies to: vehicles with Audi drive select and efficiency mode
In efficiency mode, economy tips are shown
briefly on the instrument cluster display in cer­
tain situations where fuel economy is affected.
By following these economy tips, you can save

fuel.

To clear an economy tip from the display immedi­
ately, press the left thumbwheel on the multi­
function steering wheel.
To activate/deactivate economy
tips:
Select the
following on the infotainment system:
|MENU|

button > Car
>
Audi drive select. Select: efficien­
cy
>
right control button > Economy tips.
© Note
- The date, the time and the time/date dis­
play format can be changed via the infotain­
ment system
^page
255.
- The economy tips are not always displayed
in every conceivable situation, but are delib­
erately spaced out over time.
- Once you have cleared an economy tip from
the display, it will not appear again until the
next time you switch on the ignition.
