Roof carrier
Important safety notes
GWARNING
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.
You will find information on the maximum roof
load in the "Technical data" section
(
Ypage 415).
!Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to avoid damage to the vehicle.
Position the load on the roof carrier in such
a way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is instal-
led you can:
Rfully raise the sliding sunroof/panorama
roof with power tilt/sliding panel
Ropen the tailgate fully
An incorrectly secured roof carrier or roof
load may become detached from the vehicle.
You must therefore ensure that you observe
the roof carrier manufacturer's installation
instructions.
Vehicles with a panorama roof with
po

wer tilt/sliding panel: the panorama roof
with power tilt/sliding panel cannot be
opened if a roof carrier is installed. The pan-
orama roof with power tilt/sliding panel can
still be raised to allow ventilation of the vehi-
cle interior.
If the panorama roof with power tilt/sliding
panel makes contact with a roof carrier
approved by Mercedes-Benz, the sunroof will
lower slightly but remain raised at the rear.
