Operation in winter
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
This service includes the following:
R
oil change, if the engine oil currently used
does not have adequate low temperature
characteristics or if these are no longer
sufficient due to aging
R
the antifreeze/anticorrosion
concentration in the coolant is checked.
R
the addition of a concentrated cleaning
agent to the water in the windshield
washer/headlamp cleaning system
R
battery check
R
tire change
Prior to the onset of winter, ensure that snow
chains are stowed in the vehicle
(Y page 263).
Do not cover the surface of the radiator or the
radiator grill, even in winter. Doing so could
cause the engine diagnostics to record false
or incorrect data. The recording of specific
engine diagnostic data is legally prescribed
and must therefore be correct, clear and
comprehensible at all times.
You will find information about diesel fuel for
use at low outside temperatures in the
"Operation" section (Y page 157).
Please also observe the information about
winter driving (Y page 113).
You will find information about winter tires
and about driving with snow chains in the
"Wheel and tires" section (Y page 156).

Fuel
Important safety notes
G
WARNING
Fuel is highly flammable. Fire, naked flames
and smoking as well as the use of auxiliary
heaters (sparks) are therefore prohibited
when handling fuel.
Switch off the engine and the auxiliary heating
before refueling.
G
WARNING
Avoid any contact with fuels.
You can damage your health if your skin
comes into direct contact with fuel or if you
inhale fuel vapors.
!
Filter the fuel before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers.
This will prevent malfunctions in the fuel
system due to contaminated fuel.
!
Refuel only with commercially available
vehicle diesel fuel, ULTRA-LOW SULFUR
DIESEL with a sulfur content no greater
than 15 ppm. Fuels such as fatty acid
methyl ester FAME (bio-diesel fuels),
marine diesel, heating oil etc. may not be
used as a diesel fuel mixture.
Refuel with B5 bio-diesel only if it fulfills the
requirements listed under "Fuel quality".
Do not use any fuel additives, and use
approved flow improvers only when
necessary.
There is otherwise a risk of impaired engine
performance or engine and catalytic
converter damage. The use of fuel additives
is always the responsibility of the vehicle
operator and may result in restrictions to
or the loss of the New Vehicle Limited
Warranty.
