Roof carrier
Important safety notes
G WARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character-
istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.
There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
! Mercedes-Benz recommends that you only
use roof carriers that have been tested and
approved for Mercedes-Benz vehicles. This
helps to prevent damage to the vehicle.
Position the load on the roof carrier in such a
way that the vehicle will not sustain damage
even when it is in motion.
Ensure that, depending on the vehicle's
equipment, you can raise the sliding sunroof
fully and open the trunk lid fully when the roof
carrier is installed.
! To avoid damaging or scratching the covers,
do not use metallic or hard objects to open
them.
You will find information on the maximum roof
load in the "Technical data" section
( Y
