Low outsid etemperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specification sofstandard EN 590
can hel ptoprevent operatin gproblems. At
exceptionall ylow tempera tures, it is possible
that the flow properties of the fuel ma ybe
inadequate. This is also the case for fuel that
has not been adapted to the climatic specifi-
cations ,e.g. diese lfuel for warmer areas.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective- ness of
aflow improver is not guaranteed with
every fuel.

wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-

Important safety notes
G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle when the key is removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to aserious or fatal accident. G
Risk of fire
Make sure that the exhaust system does not
under any circumstances com einto contact
with easily ignitable material such as dry grass
or petrol .Otherwise, the flammable material
may ignite and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be appl ied.
R on vehicles wit hmanual transmission,
engage first gear or reverse gear.
R on vehicles with automatic transmission,
the transmissio nmust be in position Pand
the key must be removed from the ignition
lock.
R on steep uphill or downhill gradients, turn
the front wheel stowards the kerb. Parking brake
