the case of a fully electric
trailer hitch, retract the ball nec k. Depending on
the bicycle rack 's design, up to
th re e bicycles can be transpor ted on the bicycle
ra ck.
When mounted byattaching toball head 1,the
maximum load capacity is 75 kg. The maximum load capacity is calculated from
the
we 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 (/ page 169).
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 370).

The lar gerth e distance between the load's centre

Therefore, obser vethefo llowing no tes:
R mount heavy bicycles as close totheve hicle
as possible
R always distribute the load on the bicycle rack
as evenly as possible across theve hicle's lon-
gitudinal axis
Mercedes-Benz recommends removing all de tach-
able parts from bicycles (e.g. bask ets, ch ild seats,
re ch arge able batteries) before loading them onto
th e bicycle rack . This will impr ovethe aerody- namic
resis tance and centre of grav ity of the bicy-
cle rack.
Alw ays secure the bicycles toprev ent them 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 driving
ch aracteristics and rear view may be impaired. In
addition, aerodynamic resis tance and the load on
th e trailer hitch will increase. Load distribution on

If one or more tyre sizes precede a tyre pressure,
th efo llowing tyre pressure information is only
va lid forth ose tyre sizes and their respecti veload
condition.
If th e preceding tyre sizes are complemented by
th e+ symbol, the tyre pressure information

consum ption may then increase slightl y.
The load conditions "pa rtially laden" and "fully

The system checks the tyre pressure and the tyre
te mp erature of the tyres /t tedtotheve hicle by
means of a tyre pressure sensor.
The tyre pressure and the tyre temp erature
appear in the on-board computer (/ page 371).
If th ere is a substantial pressure loss or if the tyre
te mp erature is excessive, you will be warned with
display messages (/ page 466) ortheh wa
rning lamp in the inst rument cluster
(/ page 490).
The tyre pressure monitoring system is only an
aid. It is the driver's responsibility toset the tyre
pressure tothere commended cold tyre pressure
suitable forth e operating situation.
In most cases, the tyre pressure monitoring sys-
te m will automatically update the new refere nce
va lues aTer you ha vechanged the tyre pressure.
Yo u can, ho wever, also update there fere nce val-
ues byrestarting the tyre pressure monitoring
system manually (/ page 372).
