Driving and operating107Starting the engine
Turn key to position 1 to release the
steering wheel lock.
Operate clutch and brake pedal. Do not operate the accelerator pedal. Turn key briefly to position 3 and
release: an automatic procedure
operates the starter after a brief
delay, until 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 -30 °C.
Required is an engine oil with the
correct viscosity, the correct fuel,
performed services and a sufficiently
charged vehicle battery.
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-starting engine:
● clutch pedal not operated
● timeout occurredTurbo 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.
Depending on driving conditions, the
overrun cut-off may be deactivated.
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.
The engine is started automatically as soon as the clutch is depressed.
122Driving and operatingThe system can not operate when no
lane marking is detected.Fuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
equivalent.
The engine is capable of running with
fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended
octane rating. A lower 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 equivalent can lead todeposits or engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine specific requirements
regarding octane rating are given in
the engine data overview 3 171. A
country specific label at the fuel filler
flap can supersede the requirement.
Vehicle care157
3. Ensure the jack is correctlypositioned under the relevant
vehicle jacking point.
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 and remove jack.
9. Install the wheel wrench ensuring that it is securely located and
tighten each bolt in a crosswise
sequence. Tightening torque is
140 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 centre
cap on alloy wheel.
11. Stow and secure the replaced wheel, the vehicle tools 3 144 and
the adapter for the locking wheel
bolts 3 52.
12. Check the tyre pressure of the installed tyre and the wheel bolt
torque as soon as possible.Stowing a damaged wheel in the
load compartment using a strap
Use the strap placed in the tool box.
Vehicle tools 3 144.
The spare wheel well is not designed for all permitted tyre sizes. If a wheel
wider than the spare must be stowed
in the spare wheel well after changing
wheels, the floor cover can be placed on the projecting wheel.
1. Remove load compartment cover and lift up load compartment floor.
Position the tool box and the
damaged wheel to stand upright
into the tool box spare.
2. Pull up the release knob on top of
the rear seat and move backrest
forwards.
