Important safety notes
GWAR NING
When you load the roof, the center of gravity
of the veh iclerises and the driving character-
istics change. Ifyou exceed the maximum roof
load, the driving characteristics, as wellas

approved for Mercedes-Benz veh icles. This
helps to avoid damage to the veh icle.
Position the load on the roof carrier insuch a
way that the veh icle willnot sustain damage
even when it is inmotion.
