Service display
The engine oil life system informs
when to change the engine oil and
filter. Based on driving conditions, the interval at which an engine oil and
filter change will be indicated can vary
considerably.
The remaining oil life duration menu
is displayed in the Driver Information
Centre 3 116.

turn signal lever. Turn the adjuster wheel to select Remaining Oil Life .
Remaining oil life duration is indicated
in percentage.
ResetPress SET/CLR on turn signal lever
for several seconds to reset. The
ignition must be switched on but
engine not running.
Instruments and controls107The system must be reset every time
the engine oil is changed to ensure
proper functionality. Seek the
assistance of a workshop.

engine oil and filter changed by a
workshop within one week or
300 miles (whichever occurs first).

Possible pages are: ● economy trend
● economy index
● top consumers
Economy trend
Displays the average consumption
development over a distance of
31 miles. Filled segments display the
consumption in 3.1 mile steps and
shows the effect of topography or
driving behaviour on fuel
consumption.
Graph can be reset by pressing
SET/CLR .
Economy index
The current fuel consumption is
indicated on an economic scale. For
economical driving, adapt driving
style to keep the filled segments
within the Eco area. The more
segments are filled, the higher the
fuel consumption.
Simultaneously, the average
consumption value is indicated.
Top consumers
List of top comfort consumers
currently switched on is displayed in descending order. Fuel saving
potential is indicated.
During sporadic driving conditions,
the engine will activate the heated
rear window automatically to increase
the engine load. In this event, the
heated rear window is indicated as
one of the top consumers, without
activation by the driver.
150Driving and operatingDriving hints
Control of the vehicle
Never coast with engine not
running
Many systems will not function in this situation ( e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop.
Stop-start system 3 153.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.Use only floor mats which fit properly
and are fixed by the retainers on the
driver's side.
Steering
If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.
Control indicator c 3 113.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging of the
vehicle battery.
