126Driving and operatingStarting the vehicle at low
temperatures
In extremely cold temperatures, i.e.
below -20 °С, it may be necessary to
crank the engine for up to
30 seconds for it to start.
Turn key to position START and hold
until engine starts. Start attempts
should not last longer than
30 seconds. If engine does not start, wait 10 seconds before repeatingstarting procedure.
Ensure the engine oil is of the correct viscosity, the correct fuel is used,
vehicle services are performed
regularly and the battery is sufficiently
charged.
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.
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. It starts the engine
automatically as soon as the clutch is depressed. 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.Deactivation
Deactivate the stop-start system
manually by pressing s. The
deactivation is indicated when the
LED in the button extinguishes.
Fuel economy mode 3 122.
Autostop If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal
● set the lever to neutral
● release the clutch pedal

160Vehicle careWe recommend the use of the same
grade of engine oil that was used at
the last oil change.
The engine oil level must not exceed the MAX mark on the dipstick.Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 211, Engine oil quality/
viscosity 3 202.
Fit the cap on straight and tighten it.
Control indicators for engine oil
pressure I 3 88, engine oil life ¢
3 89, and low engine oil S 3 89.
Once the engine oil has been
changed, the engine oil life monitor needs to be reset. Seek the
assistance of a workshop.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be between the
MIN and MAX marks. Top up if the
level is low.9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.

202Service and maintenanceConfirmations
Confirmation of service is recorded in the Service and warranty booklet.
The date and mileage is completed
with the stamp and signature of the
servicing workshop.
Make sure that the Service and
warranty booklet is completed
correctly as continuous proof of
service is essential if any warranty or goodwill claims are to be met, and is
also a benefit when selling the
vehicle.
Service interval with remaining
engine oil life duration
The service interval is based on
several parameters depending on
usage.
The service display lets you know
when to change the engine oil.
Service display 3 80.Recommended fluids,
lubricants and parts
Recommended fluids andlubricants
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
ageing 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
diesel engines. If it is unavailable,
engine oils of other listed qualities
have to be used.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 206.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 206.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.

Service and maintenance203Engine oil viscosity
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 3 206.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze. Consult a
workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C. This concentrationshould be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional coolant additives will be rejected.
Brake and clutch fluidOver time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified interval.
AdBlue
Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 131.
