Instrument cluster

When engine oil temperatures are low, the dis-
play --- °F (--- °C) appears in the instrument clus-
ter. The engine has reached its operating temper-
ature when the engine oil temperature is be-
tween 176 °F (80 °C) and 248 °F (120 °C) under
normal driving conditions. The engine oil temper-
ature may be higher if there is heavy engine load
and high temperatures outside. This is not a
cause for concern as long as the B or 2 indica-
tor lights do not turn on.
Boost indicator
Applies to: vehicles with boost indicator
Depending on vehicle equipment, the current en-
gine load (meaning the current boost pressure)
may be indicated by a bar in the instrument clus-
ter.

Short-term memory and long-term memory
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 will be included when calculating the
current 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.
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 gauge also
shows the current total consumption of all other
equipment.
