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 367).
!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/panorama roof
with power tilt/sliding panel fully
Ropen the trunk lid fully
!To avoid damaging or scratching the covers,
do not use metallic or hard objects to open
them.
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 power
tilt/sliding panel: the panorama roof with
power tilt/sliding panel cannot be opened if a
roof carrier is installed. The panorama roof with power tilt/sliding panel can still be raised to
allow ventilation of the vehicle 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.
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.

include such items as chargers for mobile
phones.
If you use the sockets for long periods when the
engine is switched off, the battery may dis-
charge.
An emergency cut-out ensures that the on-
board voltage does not drop too low. If the on-
board voltage is too low, the power to the sock-
ets is automatically cut. This ensures that there
is sufficient power to start the engine.
If you have connected a device to the 12 V
socket, leave the cover of the stowage com-
partment open. This prevents the cover from
