146Driving and operatingExchanging AdBlue
If less than 5 litres of AdBlue have
been refilled during the last 2 years,
the remaining fluid should be
exchanged since AdBlue has a
limited durability. Seek the assistance of a workshop.Caution
Disregard could lead to damage to
the selective catalytic reduction
system.
Automatic transmission
The automatic transmission permits
automatic gearshifting (automatic
mode) or manual gearshifting
(manual mode).
Manual shifting is possible in manual
mode by tapping the selector lever
3 148.
Transmission display
The mode or selected gear is shown
in the transmission display.
In automatic mode, the driving
programme is indicated by D in the
Driver Information Centre.
In manual mode, M and the number
of the selected gear is indicated.
R indicates reverse gear.
N indicates neutral position.
P indicates park position.

Service and maintenance235Engine oil viscosity grades
The SAE viscosity grade gives
information on 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 3 238.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. 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 3 143.
