138Driving and operatingAutomatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate accelerator pedal.
Press and release Start/Stop: an
automatic procedure operates the
starter with a short delay until the
engine is running.
Before restarting or to switch off the engine when vehicle is stationary, press Start/Stop once more briefly.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 139.
Automatic transmission: during an
Autostop, the engine can be started
by releasing the brake pedal 3 139.
Emergency shut off during driving If the engine needs to be switched offduring driving in case of emergency,
press Start/Stop for five seconds.9Danger
Switching off the engine during
driving may cause loss of power
support for brake and steering
systems. Assistance systems and
airbag systems are disabled.
Lighting and brake lights will
extinguish. Therefore power down the engine and ignition while
driving only when required in case of emergency.
Starting the vehicle at low
temperatures
Starting 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 requires a
warming phase of approx.
five minutes. The selector lever must
be in position P.
Heating functionalities
Notice
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will
be resumed after some minutes.
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 pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.

156Driving and operatingStandard mode
This mode is calibrated for a low levelof wheel spin, based on the different
types of grip generally encountered in
normal day to day driving.
Everytime the ignition is switched off,
the system is automatically reset to
this mode.
Snow mode
This mode adapts to the grip
conditions encountered by each
wheel when starting.
When advancing, the system
optimises wheel spin to guarantee the
best acceleration based on the
available traction. Recommended in
cases of deep snow and steep
inclines.
This mode is active up to a speed of
30 mph.
Mud mode
This mode allows considerable wheel
spin at start-up for the wheel with the
least grip, this removes mud and re-
establishes traction.
Simultaneously, the wheel with the
most grip is provided with the most
torque possible.
This mode is active up to a speed of
50 mph.

Driving and operating193System limitationsIn the following situations, the system
may not operate properly or even not operate at all:
● Poor visibility caused by inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc.
● Dazzle caused by headlamps of an oncoming vehicles, low sun,
reflections on damp roads,
leaving a tunnel, alternating
shade and light etc.
● Windscreen area in front of the camera covered by dirt, snow,
stickers etc.
● No lane markings detected or multiple lane markings due to
roadworks
● Close vehicles ahead
● Winding roads or narrow roadsFuel
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 3 243. A
country-specific label at the fuel filler
flap can supersede the requirement.
Fuel additives outside Europe
Fuel should contain detergent
additives that help prevent engine
and fuel system deposits from
forming. Clean fuel injectors and
intake valves will allow the emission
control system to work properly.

226Vehicle careEnsure that the edge of the body
fits into the notch of the jack.
Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
5. Unscrew the wheel nuts. 6. Change the wheel. Spare wheel 3 227
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuringthat it is located securely and
tighten each bolt in a crosswise
sequence. Tightening torque is
115 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
11. Stow the replaced wheel 3 227,
the vehicle tools 3 216 and the
adapter for the locking wheel nuts.
12. 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.Jacking position for lifting platform
Rear arm position of the lifting
platform centrically under the relevant vehicle jacking point.
