Fig. 16 Instrument cluster: fuel consumption display
Resetting values to zero
Requirement: the Fuel consumption, Short-term
memory, or Long-term memory display must be
selected.
> To reset the values in the respective memory to
zero, press and hold the left thumbwheel on
the multifunction steering wheel for one sec-
ond. Or
> On the multifunction steering wheel, select:
the right control button > Reset values*.
The following displays are available, depending
on vehicle equipment:
— Date and time > page 230
— Plug-in hybrid drive: range > page 81
— Average consumption > page 22
— Short-term memory overview
— Long-term memory overview
— Energy consumers > page 22
— Driver assistance > page 115
The short-term memory collects driving informa-
tion from the time the ignition is switched on un-
til it is switched off. If you continue driving within
two hours after switching the ignition off, the
new values are included when calculating the cur-
rent trip information.
Unlike the short-term memory, the long-term
memory is not erased automatically. You can se-
lect the time period for evaluating trip informa-
tion yourself.
22
Average consumption
The current consumption can be shown using a
bar graph. The average consumption stored in
the short-term memory is also displayed. If the
bar is green, your vehicle is saving energy (for ex-
ample, using recuperation).
Energy consumers*
The Energy consumers view lists other equip-
ment that is currently affecting fuel consump-
tion. The display shows up to three equipment
items. The equipment using the most power is
listed first. If more than three items using power
are switched on, the equipment that is currently
using the most power is displayed. A chart also
shows you the current total of all other consum-
ers.
(i) Tips
The date, time of day, and time and date for-
mat can be set in the Infotainment system
