is running. Because of the checking
procedure, the engine starts running after a short delay.
Possible reasons for a non-starting engine:
■ Clutch pedal is not operated.
■ 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.Stop-start system
The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a traffic jam. It starts the engine
automatically as soon as the clutch is
depressed. A vehicle battery sensor
ensures that an Autostop is only
performed if the vehicle battery is
sufficiently charged for a restart.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Deactivation
Deactivate the stop-start system
manually by pressing the eco button.
The deactivation is indicated when
the LED in the button extinguishes.
Autostop
If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
■ Depress the clutch pedal.
■ Set the lever in neutral.
■ Release the clutch pedal.
The engine will be switched off while
the ignition stays on.

146Driving and operatingFuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or E DIN 51626-1 or equivalent.
The 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 3 209. 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 liquid gas
operation Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under
its French name GPL (Gaz de Pétrole Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between
105 and 115, depending on the
butane proportion. LPG is stored
liquid at around 5 - 10 bar pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient
pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.

Vehicle care187
Some versions have sill
panellings with covered vehicle
jacking points: pull out the cover
at the respective jacking point
firstly.
4. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Attach jack handle and with the
jack correctly aligned rotate handle until wheel is clear of theground.
5. Unscrew the wheel bolts.
6. Change the wheel.
7. Screw on the wheel bolts.
8. Lower vehicle.
9. Install the wheel wrench ensuring that it locates securely and tighten
each bolt in a crosswise
sequence. Tightening torque is
110 Nm.
10. Align the valve hole in the wheel cover of the steel wheel with the
tyre valve before installing.
Install wheel bolt caps or center
cap on alloy wheel.
11. Stow and secure the replaced wheel, the vehicle tools 3 173 and
the key adapter 3 52.
12. Check the tyre pressure of the installed tyre and the wheel bolt
torque as soon as possible.
Have the defective tyre renewed or
repaired as soon as possible.
