Driving and operating149Emergency shut off during drivingIf 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 Note
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.
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.

Service and maintenance255Recommended fluids,

Recommended fluids and lubricants
Only use products that meet the
recommended specifications.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for
petrol and diesel engines. If it is
unavailable, engine oils of other listed qualities must be used.
Recommendations for petrol engines
are also valid for Compressed Natural
Gas (CNG), Liquified Petroleum Gas
(LPG) and Ethanol (E85) fuelled
engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 259.
Topping up engine oilCaution
In case of any spilled oil, wipe it up and dispose it properly.
Engine oils of different manufacturersand brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oils for all petrol
engines with only ACEA quality is
prohibited, since it can cause engine
damage under certain operating
conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 259.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 259.
