Loading
Loading
Roof rack*
1Trim

Open trim1 at the trim strips in the
roof.

Secure the roof rack according to
manufacturer’s instructions for instal-
lation.
Loading instructions
The total load weight including vehicle
occupants and luggage/cargo should not
exceed the total load limit indicated on the
corresponding placard located on the driv-
er’s door B-pillar.
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Always place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.
The heaviest portion of the cargo should
always be kept as low as possible since it
influences the handling characteristics of
the vehicle.
Warning!
G
Only use roof racks approved by
Mercedes-Benz for your vehicle model to
avoid damage to the vehicle.
Follow the manufacturer’s installation
instructions. Otherwise, an improperly at-
tached roof rack system or its load could be-
come detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the
vehicles without the roof rack loaded.
!
Load the roof rack in such a way that the ve-
hicle cannot be damaged while driving.
Make sure


you can fully raise the tilt/sliding sunroof


you can fully open the trunk
