When objects are unsecured or inadequately
secured, they can slip, tip over or be thro wn

WARNING Risk of bu rning from theta il‐
pipe or tailpipe trim
The tailpipe and tailpipe trim can become

When securing loads, obse rveth efo llowing:
R Fill spaces between the load and the cargo

Use the cargo tie-down points or tie-down
ey es and the loading rails in the cargo com‐
partment or on the load sur face.
Only use tie downs, such as lashing rods, lock
ro ds or lashing nets and lashing stra ps, which
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

Loads, and heavy loads in particular, should
preferably be secured using the tie-down
