plates (3) to side.
2. Mount cross bar (1) on roof railings.

Important!
Do not use the pop-up feature of the sliding / pop-up roof
when positioning and / or placing luggage above it, to

Long cargo items should not extend beyond the vehicle
length and should be securely fastened at the front and
rear.
Prior to and during an extended trip check the roof load,
and retighten the knurled-head screws if necessary.
The heaviest portion of the cargo should always be kept
as low as possible since it influences the handling
characteristics of the vehicle.
When driving without roof luggage, the cross bars may
be removed to reduce wind noise.
For load capacity see page 326.Note:
Use only roof racks approved by Mercedes-Benz for your
vehicle model. They mount to the roof railings and do
not require additional supports (e.g. suction cups or
legs). Such supports may lead to marring of the paint or
denting of the roof. For further information inquire at
your Mercedes-Benz Center.
