Bicycle rack function

WARNING Risk of an accident if the bicycle rack is used incorrectly

The bicycle rack may become detached from the vehicle in the following cases:

the permissible load capacity of the trailer hitch is exceeded.
the bicycle rack is used incorrectly.
the bicycle rack is secured to the ball neck beneath the ball head.

Observe the following for your own safety and that of other road users:

always adhere to the permissible load capacity of the trailer hitch.
always observe the permissible rear axle load of the towing vehicle.
use the bicycle rack only to transport bicycles.
always mount the bicycle rack properly by attaching to the ball head and the ball neck guide pin, if possible.
when transporting four bicycles, always use bicycle racks which have additional support on the ball neck guide pin.
use only bicycle racks approved by Mercedes-Benz.
always observe the bicycle rack operating instructions.

NOTE Damage to, or cracks on, the trailer hitch due to unsuitable bicycle racks or bicycle racks being used incorrectly

use only bicycle racks approved by Mercedes-Benz.

NOTE Increased risk of damage to property due to folded-out ball neck

When the trailer is not coupled or the bicycle rack is attached, fold in the ball neck or, in the case of a fully electric trailer hitch, retract the ball neck.

Trailer hitch (example with additional guide pin)

Depending on the bicycle rack's design, different numbers of bicycles can be transported.

The following bicycle rack designs are possible:

When mounted by attaching to ball head , the maximum load capacity is 75 kg. You can transport up to three bicycles.
When mounted on ball head and guide pin , the maximum load capacity is 100 kg. You can transport up to four bicycles.

The maximum load capacity is calculated from the weight of the bicycle rack and the bicycle rack load.

Observe the notes on driving with a roof load, trailer or fully laden vehicle More.

When using a bicycle rack, set the tyre pressure for increased load on the rear axle of the vehicle. Further information on the tyre pressure can be found in the tyre pressure table More.

Notes on loading

The larger the distance between the load's centre of gravity and the ball head, the greater the load on the trailer hitch.

Observe the following notes:

mount heavy bicycles as close to the vehicle as possible
always distribute the load on the bicycle rack as evenly as possible across the vehicle's longitudinal axis

Mercedes-Benz recommends removing all detachable parts from bicycles (e.g. baskets, child seats, rechargeable batteries) before loading them onto the bicycle rack. This will improve the aerodynamic resistance and centre of gravity of the bicycle rack.

Always secure the bicycles to prevent them from moving around and check them at regular intervals to ensure that they are secure.

Do not use tarpaulins or other covers. The driving characteristics and rear view may be impaired. In addition, aerodynamic resistance and the load on the trailer hitch will increase.

Load distribution on the bicycle rack

Vertical distance between centre of gravity and ball head

Horizontal distance between centre of gravity and ball head

The centre of gravity is on the vehicle's centre axis

Observe the following information when loading the bicycle rack:

Loading the bicycle rack
	3 bicycles	4 bicycles
Total weight of bicycle rack and load	Up to 75 kg	Up to 100 kg
Max. distance	420 mm	420 mm
Max. distance	300 mm	400 mm

When transporting four bicycles or a total weight between 75 kg and 100 kg, always use bicycle racks with additional support on the trailer hitch guide pin.
