stationary, press Start/Stop once
more briefly.
To start the engine during an
Autostop:
● Manual transmission: during an Autostop, the engine can be
started by depressing the clutch
pedal 3 137.
● Automatic transmission: during an Autostop, the engine can be
started by releasing the brake
pedal 3 137.
Emergency shut off during driving If the engine needs to be switched offduring driving in case of emergency,
press Start/Stop for 5 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. 5 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.
178Driving and operating
Diesel fuel that meets standard
EN590 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 7% Fatty Acid Methyl
Ester).
Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid
Methyl Ester).
Paraffinic Diesel fuel that meets
standard EN15940 mixed with a
biofuel that meets standard
EN14214 (possibly containing up to 7% Fatty Acid Methyl Ester).
The use of B20 or B30 fuel meetingstandard EN16709 is possible in your
Diesel engines. However, this use,
even occasional, requires strict
application of the special servicing
conditions referred to as "Arduous
conditions".
For more information, contact a
dealer or a qualified workshop.
Caution
The use of any other type of (bio)
fuel (vegetable or animal oils, pure
or diluted, domestic fuel etc.) is
strictly prohibited (risk of damage
to the engine and fuel system).
Note
The only Diesel additives authorised for use are those that meet the
B715001 standard.
Low temperature operation
At temperatures below 0 °C, some
diesel products with biodiesel blends may clog, freeze or gel, which mayaffect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0 °C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20 °C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage on the fuel
injection system.
Driving and operating179Fuel 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 as a
liquid at a pressure of approx.
5-10 bar.
The boiling point depends on the
pressure and the 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 functioning of the LPG system can only be guaranteed with liquid
gas which complies with the minimum
requirements of DIN EN 589.

Refuelling
9 Danger
Before refuelling, switch off
ignition and any external heaters
with combustion chambers.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.
190Vehicle careEngine oilCheck the engine oil level manuallyon a regular basis to prevent damage
to the engine. Ensure that the correct specification of oil is used.
Recommended fluids and lubricants
3 231.
The maximum engine oil
consumption is 0.6 l per 1000 km.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 minutes.Pull out the dipstick, wipe it clean,
reinsert it fully, pull out and read the
engine oil level.
When the engine oil level has
dropped to the MIN mark, top up the
engine oil.
Different dipsticks are used
depending on engine variant.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out. If the oil exceeds the maximum level, do
not start the vehicle and contact a
workshop.
