136Driving and operatingStarting the vehicle at low
temperatures
Diesel engines
The start of the engine without
additional heaters is possible down to -25 °С.
Petrol engines
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.
With temperatures below -30 °C, the
automatic transmission requires 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 need to hold the key in position 3.
Once applied, the system will go on starting automatically until the engineis 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.
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.
On vehicles with manual
transmission, the engine is started
automatically as soon as the clutch is
depressed.
On vehicles with manual transmission automated, the engine is started
automatically as soon as the brake
pedal is released.
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.

Driving and operating177
DeactivationThe system is deactivated by
pressing ), LED in the button
extinguishes.
At speeds below 56 km/h 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 e.g. heavy rain, snow,
direct sunlight or shadows.
The 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
E DIN 51626-1 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 E DIN 51626-1 or
equivalent can lead to deposits 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 3 244. A
country specific label at the fuel filler
flap can supersede the requirement.
A country specific label at the fuel filler
flap can supersede the requirement.
Fuel for diesel engines Only use diesel fuel that complies
with EN 590.

damaged.
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 centre
cap on alloy wheel.
11. Install vehicle jacking point cover.
12. Stow and secure the replaced wheel, the vehicle tools 3 211 and
the adapter for the locking wheel
bolts 3 57.
13. 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.
