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.
Depending on the vehicle equipment, ensure that when the roof rack is fitted, the tailgate can be fully opened.
Position the load on the roof rack in such a way that the vehicle will not sustain damage even when it is in motion.
NOTE Damage to the panorama sliding sunroof caused by a non-approved roof rack
The panorama sliding sunroof may be damaged by the roof rack if you attempt to open it when using a roof rack not tested and approved for Mercedes-Benz.
When a roof rack is fitted, open the panorama sliding sunroof only if this has been tested and approved for Mercedes-Benz.
The panorama sliding sunroof may be raised to allow ventilation of the vehicle interior.
Secure the roof rack to the roof railing.
Observe the manufacturer's installation instructions.
Folding the rear seat backrest forwards
WARNING Risk of becoming trapped when adjusting the seats
When you adjust a seat, you may trap yourself or a vehicle occupant.
When adjusting a seat, make sure that no one has any body parts in the sweep of the seat.
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.
This poses the following risks in particular:
A seat or seat backrest that is not engaged can push the vehicle occupant against the seat belt. The seat belt would then not be able to provide the intended protection and could cause additional injury.
A child restraint system would no longer be supported correctly or positioned correctly and would no longer perform its intended function.
The seat backrest cannot restrain objects or goods in the luggage compartment.
Always ensure that the seat and seat backrest are engaged, especially:
before passengers travel on a seat with the easy entry and exit feature.
after adjusting the seat.
after the easy entry and exit feature is used.
after the load compartment enlargement has been folded down.
Always ensure that all vehicle occupants have their seat belts fastened correctly and are sitting properly. Particular attention must be paid to children.
If you no longer require the folded-down rear seat backrest as a loading area, fold the rear seat backrest back into place.
Make sure that the red marking of the lock verification indicator is no longer visible. Otherwise, the seat backrest will not be locked.
Requirements:
Vehicles with centre rear seat backrest: the centre rear seat backrest is not in the luggage compartment floor position.
Vehicles with a folding rear armrest: the rear armrest has been folded up.

WARNING Risk of injury if the rear bench seat/rear seat and seat backrest are not engaged
If the rear bench seat/rear seat and seat backrest are not engaged they could fold forwards, e.g. when braking suddenly or in the event of an accident.
If this is the case, the vehicle occupant would be forced into the seat belt by the rear bench seat/rear seat or by the seat backrest. The seat belt cannot protect as intended and could result in additional injury.
Objects or loads in the boot/load compartment cannot be restrained by the seat backrest.
Make sure that the seat backrest and the rear bench seat/rear seat are engaged before every trip.
NOTE Damage caused by trapping the seat belt when folding back the seat backrest
