Service display
The engine oil life system lets you
know 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.
To display the remaining engine oil
life duration use turn signal lever
buttons:
Press the MENU button to select the
Vehicle Information Menu X .
Turn the adjuster wheel to select Remaining Oil Life .
The remaining engine oil life duration
is displayed in percent in the Driver
Information Centre.
Reset
Press the SET/CLR button on turn
signal lever for several seconds to
reset. The remaining engine oil life
duration page must be active. Switch
on ignition, but engine off.
The system must be reset every time
the engine oil is changed to ensure
proper functionality. Seek the
assistance of a workshop.
Next service
When the system has calculated that
engine oil life has diminished, a
warning message appears in the
Driver Information Centre. Have
engine oil and filter changed by a
workshop within one week or
300 miles (whichever occurs first).

Driving and operating161
Do not operate the accelerator pedal.Diesel engine: turn the key to position2 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 3 and
release: an automatic procedure
operates the starter with a short delay
as long as the engine is running, see
Automatic Starter Control.
Before restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.Starting the vehicle at low
temperatures
Starting the engine without additional heaters is possible down to -25 °С for
diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct
fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission needs a
warming phase of approx. 5 minutes.
The selector lever must be in position P .
Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not need to hold the key in position 3.
Once applied, the system will go on
starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running after a short delay.Possible reasons for a non-startingengine:
■ Clutch pedal not operated (manual transmission).
■ Brake pedal not operated or selector lever not in P or N
(automatic transmission).
■ Timeout occurred.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
Overrun cut-off The fuel supply is automatically cut-
off during overrun, i.e. when the
vehicle is driven with a gear engaged but accelerator is released.
