158Driving and operating
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
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 battery.
With temperatures below -30 °C the
automatic transmission need 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 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.
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.

206Driving and operating
At speeds below 35 mph the system
is inoperable.
Fault
The lane departure warning system
may not operate properly when:
■ The windscreen is not clean.
■ There are adverse environmental conditions like heavy rain, snow,
direct sunlight or shadows.
The system can not operate when no
lane marking is detected.Fuel
Fuel for petrol enginesOnly use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable of running
with E10 fuel that fulfills these
standards. E10 fuel contains up to
10 % bioethanol.
Use fuel with the recommended
octane rating 3 275. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly increases fuel consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to EN 228 or E DIN 51626-1 or
equivalent can lead to deposits or
engine damage and may affect
your warranty.
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled combustion and engine damage.
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.

Driving and operating209
Pressing Y switches between petrol
and natural gas operation. Switching
is not possible at high loads (e.g.
strong acceleration, running at full
throttle). The LED status shows the
current operating mode.1 off=natural gas
operation1 illumi‐
nates=petrol operation1 flashes=no switching is
possible, one type of
fuel is empty
As soon as the natural gas tank is empty, petrol operation is
automatically engaged until the
ignition is switched off.
If the natural gas tank is not refuelled, the system must be manually
switched to petrol operation before
the engine is started-up again. This
will prevent damage to the catalytic
converter (overheating caused by
irregular fuel supply).
If the selector switch is operated
several times within a short time, a
switchover block is activated. The
engine remains in the current
operating mode. The block remains
active until the ignition is switched off.
A slight loss of power and torque can be expected during petrol operation.
You must therefore adapt your driving
style (e.g. during overtaking
manoeuvres) and vehicle loads (e.g.
towing loads) accordingly.
Every six months run the petrol tank
down until control indicator Y
illuminates, then refuel. This is
necessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular intervals to prevent corrosion in the
tank.Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.

Vehicle care255
4. Ensure the jack is correctlypositioned under the relevant
vehicle jacking point.
5. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
6. Unscrew the wheel nuts. 7. Change the wheel. Spare wheel 3 256
8. Screw on the wheel nuts.
9. Lower vehicle.
10. Install the wheel wrench ensuring that it locates securely and tighten
each nut in a crosswise
sequence. Tightening torque is
140 Nm.
11. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
12. Install vehicle jacking point cover.
13. Stow the replaced wheel 3 256,
the vehicle tools 3 244 and the
adapter for the locking wheel nuts
3 65.
14. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.
Have the defective tyre renewed or
repaired as soon as possible.
