Risk of accident
Have the tightening torque checked immedi-
ately after awheel is changed. The wheels
coul dwork loose if they are not tightened to
at orqu eof130 Nm.

i When you are driving with the emergency
spare wheel fitted, the tyre pressure loss warning system cannot function reliably.
Only restart the tyre pressure loss warning
system when the defective wheel has been
replaced with
anew wheel. MOExtended run-
flat system
Th eM OEx tended run-flat system allo wsyou
to continue driving the vehicle even when one
or more tyres los eall air pressure.
The MOExtended run-flat system may only be
used in conjunction with the activated tyre
pressure loss warnin gsystem or with the acti-
vated tyre pressure monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure los swarning
appears in the multifunction displ ay.
Yo um ust not exceed amaximum spee dof
80 km/h. G
Ris
kofa ccident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to alarge
exten tonthe loads placed on the vehicle. It
can be shorter due to high speeds, aheavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you driv ecarefully and conserva-
tively. 284

! For safety reasons, Mercedes-Ben zrec-
ommends that you only use tyres, wheels
and accessories which have been approved
by Mercedes-Ben zspecifically for your
vehicle. These tyres have been specially
adapted for use with the contro lsystems,
such as AB SorESP®
,a nd are marked as
follows:
R MO =Mercedes-Ben zOriginal
R MOE =Mercedes-Ben zOriginal Extended
(tyres with run-flat characteristics)
R MO1 =Mercedes-Ben zOriginal (AMG)
Only use Mercedes-Benz Original Extended
tyres on wheels that have been specifically
approved by Mercedes-Benz.
If you use other tyres, wheels and acces-
sories, Mercedes-Benz cannot accept any
responsibility for damage that may result
from this. Further informat ionabout tyres,
wheels and approved combinations can be obtained from any Mercedes-Benz Service
Centre.
! If you fit tyres other than those tested and
recommended by Mercedes-Benz, charac-
teristics such as handling, noise levels and
fuel consumption, etc. may be adversely
affected. In addition, when driving with a
load, tyre dimensional variations could
caus ethe tyres to com einto contact with
the bod ywork and axle components. This
could result in dam agetot he tyres or the
vehicle.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Servic eCentre.
i You will fin datable of tyre pressures on
the insid eofyourv ehicle' sfuel filler flap.
For further information on tyre pressure,
see (Y page 299).
i Notes on the vehicle equipment:
Always fit the vehicle:
R with tyres of the same size on agiven axle
(left/right)
R with the same type of tyres at agiven
time (summer tyres, winter tyres,
MOExtended tyres)
i Vehicles featurin gthe MOExtended run-
fla ts ystem are not equipped with the
TIREFIT kit.
It is therefore recommended that you addi-
tionally equip your vehicle with the TIREFIT
kit if you fit tyres that do not feature run-
flat properties, e.g. winter tyres.
AT IREFIT kit is availa blef rom any qu alified
specialist workshop, e.g. aMercedes-Benz
