When mounted on ball head 1and guide
pin 2, the maximum load capacity is
10 0kg .Yo u can transpo rtup tofour bicy‐
cles.
The load capacity is calculated from thewe ight
of the bicycle rack and the bicycle rack load.
Obser vethe no tes on driving with a roof load,
trailer or fully laden vehicle (/ page192).
When using a bicycle rack , set the tyre pressure
fo r increased load on there ar axle of theve hicle.
Fu rther information on the tyre pressure can be
fo und in the tyre pressure table (/ page 385).
Note s on loading
The larger the dis tance between the load's
cent reof gr avity and the ball head, the greater
th e load on the trailer hitch.
Obser vethefo llowing no tes:
R Mount heavy bicycles as close totheve hicle
as possible.
R Alw ays distribute the load on the bicycle rack
as evenly as possible across theve hicle's
longitudinal axis. Mercedes-Benz
recommends removing all
de tach able parts from bicycles (e.g. bask ets,
ch ild seats, rech arge able bat teries) before load‐
ing them onto the bicycle rack . This will impr ove
th e aerodynamic resis tance and centre of gr avity
of the bicycle rack.
Alw ays secure the bicycles topreve ntthem from
moving around and check them at regular inter‐
va ls to ensure that they are secure.
Do not use tarp aulins or other co vers. The driv‐
ing characteristics and rear view may be
impaired. In addition, aerodynamic resis tance
and the load on the trailer hitch will increase. Load distribution on

The sy stem checks the tyre pressure and the
tyre temp erature of the tyres fitted totheve hicle
by means of a tyre pressu resensor.
The tyre pressure and the tyre temp erature
appear in the driver's display (/ page 386).
If th ere is a subs tantial pressure loss or if the
tyre temp erature is excessive, you will be
wa rned with display messages (/ page541) or
th eh warning lamp in the instrument clus ter

The tyre pressure monitoring sy stem is only an
aid. It is the driver's responsibility toset the tyre
