Driving
CAUTION:
– Clean the vicinity of the fuel tank opening before opening it and
filling up the tank.
– Take care that nothing except clean fuel can enter the tank.
The tank opening for diesel is on the
fuel tank.
Make sure that the tank is as full as
possible to prevent condensation
(especially in winter) and fuel cap is
properly closed.
NOTE: The fuel tank cap,
with the key hole on the side,
is properly closed when
turned beyond the stop until
a click is heard.
The fuel tank cap, with the
key hole on top, is properly
closed when turned up to the
stop. This type of fuel tank
cap is destroyed when it is
turned beyond the stop.
NOTE: When the vehicle is equipped with a dual fuel tank, both fuel tanks
must be refuelled separately.
If filled for the first time or after both fuel tanks are empty, start with filling the
main fuel tank.
Both fuel tanks most be filled on a regular basis to prevent problems with
aging or contaminated fuel and/or the fuel transfer pump.
If outside temperatures are persistently low, only fill up with winter diesel produced by
a reputable oil company. During the winter months, the oil companies often use
additives to prevent blockages caused by the precipitation of paraffin crystals (wax
deposits).
NOTE: Additives which are used to prevent precipitation of paraffin crystals
have a purely preventative effect. They cannot dissolve precipitated
paraffin crystals.
Always have a spare fuel fine filter in the vehicle! If it gets blocked in any
way (for example, by paraffin crystals), the filter must be replaced to
continue the drive.
AdBlue
The EAS (Emission Aftertreatment System) consumes AdBlue. The AdBlue usage
depends on:
– Vehicle configuration.
– Driving style.
