Refuel only ULSD or diesel fuel witha
sulfur content of maximum15ppm.
Usually youwill find information aboutthe fuel
grade on thefuel pump. If thereisnoidentifica‐

WARNING Risk of fire and explosion due
to fuel igniting
If youheat fuel system components, e.g. with
aheat gun or open flame, these components
could be damaged.
Fuel mayleak out and ignite. Depending on
thetype of damage, fuel might notescape
until theengine is running.

to have themalfunction rectified.
Refill onlywithcommerciallyavailable ULTRA-
LOWSULFUR DIESEL (ULSD, maximum sulfur
content 15 ppm), whichfulfills theASTMD975
standard.

Malfunctions resulting from paraffinsepara‐
tion can only be rectified by heating the
entirefuel system. Park thevehicle in a
heated garage,for example.
To prevent malfunctions, diesel fuel with
improved flow characteristicsisavailable in the
winter months. Youcan obtain further informa‐
tion on this at thegas stationorfromyour fuel
supplier.
Your vehicle is equipped withafuel preheating
system. This additionallyimprovesthe flow char‐

without risk of malfunction down to an outside
temperatureofapproximately 14.5 °F (-10°C).
