WARNING Risk of inju rydue tothe maxi‐
mum roof load being exceeded
When you place a load on thero of as well as
all outer and inner attachments, theve hicle's
center of gr avity will rise and thefa miliar driv‐
ing characteristics as well as thesteering and
braking characteristics will change. When
driving around bends, theve hicle will tilt
more heavily and may react more sluggishly
to steering mo vements.
If yo uexc eed the maximum roof load, the
driving characteristics, as well as thesteering
and braking, will be greatly impaired. #
Neverexc eed the maximum roof load
and adjust your driving style. &
WARNING Danger of accident due to
une ven loading
If yo u load theve hicle une venly, the handling
ch aracteristics as well as thesteering‑ and
braking characteristics can be heavily
impaired. #
Load theve hicle evenly. #
Secu rethe load against sliding. The driving, braking and
steering characteristics
of theve hicle change with the type of load, the
we ight and the center of gr avity of the load.
* NO
TERisk of accident if the maximum
permitted roof load is exceeded. If
th ewe ight of thero of luggage, including the
ro of rack ,exc eeds the maximum permitted
ro of load, there is a risk of an accident. #
Ensure that thewe ight of thero of lug‐
ga ge and roof rack toget her does not
exc eed the maximum permitted roof
load. #
The roof rack 's supporting feet must be
ar ranged at a uni form distan ce from
ea ch other. #
Mercedes-Benz recommends you ins tall
a st abilizer bar on theve hicle's front
axle. Fu
rther information about saf ety measures can
be found in the "T ranspo rt" section
(/ page 196).
