The single journey memory processes the infor­

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
total
jour­
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.

The following additional display may be available
in the on-board computer, depending on the ve­
hicle equipment:
- Active Cylinder Management: The engine auto­
matically 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 current or
average fuel consumption display
oFig.

selected in the instrument cluster. The cylin­
ders are reactivated under heavier load condi­

tions.

Efficiency program
3

Applies to: vehicles with efficiency program
The efficiency program can help to save
fuel.
It
evaluates fuel efficiency data, shows a list of aux­
iliary equipment affecting fuel consumption, and
suggests gear changes. It also provides economy
tips for saving
fuel.

The efficiency program uses the trip and fuel
con­

sumption data from the short-term memory.
When you clear the data from the efficiency pro­

gram,
the values in the short-term memory are
reset to zero.
The following additional displays are available in
the efficiency program, depending on the vehicle
equipment:
- Advanced gear-change indicator: The advanced
gear-change indicator is based on the same
log­

ic as the "regular" gear-change indicator. The
"regular" gear-change indicator disappears
from the display when the advanced gear-
change indicator appears
^>page
14.
- Energy consumers: The efficiency program
shows a List of energy consumers currently af­
fecting the vehicle's fuel consumption. The dis­
play shows up to three energy consumers. The
energy consumer drawing the most power ap­
pears 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 indicates the overall current
fuel consumption of all energy consumers.
- Economy
tips:
Economy tips will automatically
appear intermittently in the efficiency program •

Checking and topping up fluids
Selective catalytic
reduction (AdBLue/DEF)
General notes
Applies to: vehicles with selective catalytic reduction
On vehicles with selective catalytic reduction, a
urea solution (AdBLue/DEF) is injected into the
exhaust system upstream of
a
NOx catalytic
con­

verter in order to reduce nitrogen oxide emis­

sions.
The urea solution is known under the name
of AdBlue or DEF (Diesel Exhaust Fluid). The term
AdBlue is used below.
The AdBlue is held in a separate tank on the
vehi­

cle.
AdBlue consumption is approximately 1.0 -
2.5% of diesel fuel consumption.
As soon as a message appears in the instrument
cluster display reminding you to refill AdBlue,
you must refill the AdBlue tank or have this done
by
a
qualified workshop
^>page
293.
Checking the remaining range
The remaining (estimated) range for the current

AdBLue
level can be displayed on the on-board
computer:
- Vehicles with analogue instrument cluster

•=>
page 20.
- Vehicles with virtual cockpit*
<$page
19.
-The instrument cluster display will
tell
you
how far you can drive before the tank runs
dry
•=>page
292. If the AdBlue tank runs
dry, the engine cannot be started again af­
ter you switch off the ignition.
-The use of
AdBLue for
the operation of this
vehicle is required by Law.
Instrument cluster display
Applies to: vehicles with selective catalytic reduction

The
display informs you if the AdBlue level is too
low or if a system malfunction occurs.
Low AdBlue level
You will be informed if the amount of AdBlue in
the tank falls below a certain
Level.
Add at least
the minimum (smaller) amount of AdBlue
