Attaching a roof rack
WARNING Risk of injury if the maximum roof load is exceeded
When you load the roof, the centre of gravity of the vehicle rises and the usual driving characteristics as well as the steering and braking characteristics change. During cornering, the vehicle tilts more strongly and may react more sluggishly to steering movements.
If you exceed the maximum roof load, the driving characteristics, as well as the steering and braking characteristics, will be greatly impaired.
Always comply with the maximum roof load and adjust your driving style.
NOTE Vehicle damage from non-approved roof racks
The vehicle could be damaged by roof racks which have not been tested and approved by Mercedes-Benz.
Use only roof racks tested and approved for Mercedes-Benz.
Depending on the vehicle equipment, ensure that when the roof rack is fitted, the sliding sunroof can be fully raised.

WARNING Risk of accident if seat and seat backrest are not engaged
If the seat and seat backrest are not engaged they could fold forwards, e.g. when braking or in the event of an accident.
