weight, even when accessories for the
crossbars (e.g. ski racks, bicycle racks, etc.)
are being used. Overloading the vehicle could
result in an accident. When calculating the
weight placed on the roof please make sure
to add the weight of the crossbars, accessory
racks and the load carried together.
Always adapt your driving style to the road,
traffic and weather conditions, and drive with
added caution when the roof is loaded.
Always drive with extreme care when the
carrier is loaded. Take into consideration that
when the carrier is loaded, the handling
characteristics are different from those when
operating the vehicle without a carrier loaded.
G WARNING
Do not use accessories which have not been
approved by Mercedes-Benz for use in
conjunction with these crossbars. If non-
approved accessories are used, these
accessories and/or the objects attached to
them could come loose from the vehicle,
thereby injuring you and other persons and/
or causing damage to property, including
damage to your vehicle.
! Have a second person assist you when
installing the crossbars. Otherwise, the
vehicle could be damaged.
! Objects that are attached to crossbar
system accessories must not limit or
obstruct the movement of the sliding
sunroof. Otherwise, the tilt/sliding sunroof
