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

Tyr
ep ressures that are too lo whave anega-
tiv ee ffect on vehicl esafety, which could lead
to your causing an accident.
If possible, you should only correc ttyre pres-
sures when the tyres are cold. Depending on
the ambien ttemperature, the speed you are
driving at and the load on the tyres, the tyre
temperatur eand thus the tyre pressure may
chang ebyapproximately 10 kPa (0. 1bar,
1.5 psi) per 10 †. Take this int oaccount
whe ncheckin gthe pressur eofwarm tyres
and only correct it if it is too low for the cur-
rent operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the servic elife of the tyres
R cause increased tyre damage
R have anegativ eeffect on handling charac-
teristi csand thus the driving safet y(e.g. by
causing aquapla ning)
i The tyr epressure values given for low
load sare minimum values which offe ryou
good rid ecomfor tcharacteristics.
However ,you can also use the values given
for higher loads. These ar epermissible and
will not adversely affect the running of the
vehicle. H
Environmenta
lnote
Check the tyre pressure regularly, at least
every 14 days. Tyr
epressure loss warning
Important safety notes Whil
ethe vehicle is in motion, the tyr epres-
sure loss warning system monitors th eset
tyr ep ressure using th erotational speed of
the wheels. This enables the system to detect
significant pressure loss in atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorrespondin gwarning
message will appea rinthe multifunction dis-
play. G
Risk of accident
The tyr epressure loss warning system does
not warn you of an incorrectly se ttyre pres-
sure. The table on the insid eofthe fuel filler
fla pw ill help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warnin gsystem does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detecte dbythe tyr epressure loss
warning system.
Th et yre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign objec t.
In the event of asudden loss of pressure, bring
the vehicle to ahalt by braking carefully. Do
not make any sudden steering movements
when doing so.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towin gavery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof).
Resta rting the ty re pressur eloss warn-
ing system Restart the tyre pressure loss warnin

R changed the wheels or tyres
R fitted new wheels or tyres

Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergenc yspare wheel/spare
wheel against the direction of rotation.
Observe the tim erestric tion on use as well as
the speed limitation specified on the emer-

Interchange the front and rear wheels only if
they have the same dimensions: for example
size, offset, etc.
After every wheel interchange/change, have
the tightening torque checked at aqualified
specialist workshop that has the necessary
specialist knowledg eand tool stocarry out
the work required. Mercedes-Benz recom-
mends that you use aMercedes-Ben zService
Centr efor this purpose. In particular ,work
relevant to safet yoronsafety-related sys-
tems must be carried out at aqualified spe-
cialist workshop.

ginmind
! 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
