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.
Stowage areas283
Stowage and features
Z

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 364).
!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 damage
even when it is in motion.
Depending on the vehicle equipment, ensure
that when the roof carrier is installed you can:
Rraise the sliding sunroof fully
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 panorama roof with power
tilt/sliding panel (Canada only): if a roof car-
rier is installed, the panorama roof with power
tilt/sliding panel cannot be opened. The pano-
rama roof with power tilt/sliding panel can still
be raised to allow ventilation of the vehicle inte- rior. 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.
Attaching the roof carrier
XCarefully open covers :in the direction of
the arrow and fold upwards.
XOnly secure the roof carrier to the anchorage
points under covers :.
XObserve the manufacturer's installation
instructions.

Cup holder
Important safety notes
GWARNING
If you transport objects in the vehicle interior
and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of
an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction.
RAlways stow objects in such a way that they cannot be tossed about in these or similar
situations.
RAlways make sure that objects do not pro-
trude out of the stowage spaces, luggage
nets or stowage nets.
REnsure that closable stowage spaces are
shut before beginning your journey.
RAlways stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or large objects in
the cargo compartment.
!Only use the cup holders for containers of
the right size and which have lids. The drinks could otherwise spill.
!Do not expose drinks bottles in the cup
holder in the center console to continuous,
strong and direct sunlight. The passenger
compartment in the area of the center con-
sole can otherwise be damaged by the con-
centrated and reflected sunlight.
