If you exceed the maximum roof load, the driving characteristics, as well as steering and braking, will be greatly impaired.
Never exceed the maximum roof load and adjust your driving style.
WARNING Risk of injury if unsuitable climbing aids are used
If you use openings in the vehicle's body work or detachable parts as steps, you could:
slip and/or fall.

Always use anti-slip, stable climbing aids, e.g. a suitable ladder.
NOTE Damage to the wheel arch flares and bumpers if used as a step
The wheel arch flares and bumpers can be damaged or become detached from the vehicle if you use them as a step.
Only use the two steps indicated on the rear bumper.
NOTE Vehicle damage due to non-approved roof racks
The vehicle could be damaged by roof racks that have not been tested and approved by Mercedes-Benz.
Only use roof racks approved for Mercedes-Benz.
Depending on the vehicle equipment, ensure that the sliding sunroof can be fully raised when the roof rack is fitted.
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 Maximum permissible roof load
The weight of the roof luggage, including the roof rack, must not exceed the maximum permissible roof load.
The maximum roof load is 150 kg with at least three pairs of supporting feet.
This information applies if the load is distributed evenly across the entire roof area. The maximum load per pair of supporting roof rack feet is 50 kg.
If the vehicle is at a standstill and at least three pairs of supporting feet are being used, you may exceed the maximum permissible roof load of 150 kg by a maximum of 150 kg. You can use this if you are using a roof tent, for example. It is absolutely essential to comply with the installation instructions of the roof rack manufacturer.
NOTE Damage to the covers
