DANG ER Risk of fata l injuries due to
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and can lead topoisoning. #
Never lea vethe engine running in an
enclosed space wi thout suf ficient venti‐

WARNING Risk offire caused byhot
ex haust sy stem parts
Flammable material such as lea ves, grass or
twigs may ignite if they come into contact
wi th hot parts of theex haust sy stem or
ex haust gasflow. #
Park theve hicle so that no flammable
material can come into con tact wi thhot
ve hicle components. #
In particular, do not park on dry grass‐
land or har vested grain fields. If
th eve hicle is predominantly used for short dis‐
ta nce driving or extended non-operational times,
th is could lead toa malfunction in the automatic
cleaning function forth e diesel particulate filter.
As a result, permanent blocking of the diesel par‐
ticulate filter may occur and fuel may also accu‐
mulate in the engine oil and cause engine failure.
If yo u main lydrive short dis tances, you should
drive on a free way or go for a country drive for 20
minutes every500 km (300 miles). This facili‐

partment or on the load sur face.
Only use tie downs, such as lashing rods, lock

has been tested in accordance with cur rent
st andards (e.g. DIN EN). Alw ays use the cargo
tie-down point closest tothe load; pad sharp
