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.
In the Uplevel-Display or
Uplevel-Combi-Display the remaining
oil life duration is displayed in the
Vehicle Information Menu .
In the Midlevel-Display the remaining
engine oil life duration is displayed by
the control indicator I. The ignition
must be switched on, with the engine
not running.
The menu and function can be
selected via the buttons on the turn
signal lever.
To display the remaining engine oil
life duration:Press MENU to select the Vehicle
Information Menu .
Turn the adjuster wheel to select Remaining Oil Life .
The system must be reset every time
the engine oil is changed to allow proper functionality. Seek the
assistance of a workshop.
Press SET/CLR to reset. The ignition
must be switched on, with the engine not running.

Driving and operating141Power to the Infotainment system will
continue to operate for 30 minutes or until the key is removed from theignition, regardless of whether anydoor is opened.
Starting the engine
Manual transmission: operate clutch.
Automatic transmission: operate
brake and move the selector lever to
P or N.
Do not operate accelerator pedal.
Diesel engine: turn the key to position 2 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
The start of 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.
five minutes. The selector lever must
be in position P.Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not have 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-starting
engine:
● 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.
Vehicle care199
A detected low tyre pressure
condition is indicated by the control
indicator w 3 98.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 235.
If w flashes for 60-90 seconds and
then illuminates continuously, there is
a fault in the system. Consult a
workshop.
After inflating, driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 106.
If the tyre pressure shall be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels the system
remains operational.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.Each time the tyres are replaced tyre
pressure monitoring system sensors
must be dismounted and serviced. For the screwed sensor: replace
valve core and sealing ring. For
clipped sensor: replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition
according to tyre information label or tyre pressure chart 3 235, and select
the relevant setting in the menu Tyre
Load in the Driver Information Centre,
Vehicle Information Menu 3 101 . This
setting is the reference for the tyre
pressure warnings.
The Tyre Load menu only appears if
the vehicle is in a standstill and the
parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
