re pr essur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warnin gsystem monitors the set
tyre pressure using the rotational speed of
the wheels. This enable sthe system to detect
significant pressur eloss 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.
The tyr epressure warning system does not
warn yo uofani ncorrectly set tyre pressure.
Observe the notes on the recommended tyre
pressure (Y page399).
Th et yre pressure los swarning system 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 detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign objec t. Inthe
event of asudden loss of pressure, bring the
vehicle to ahalt by braking carefully. Avoid
abrupt steering manoeuvres.
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 towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof).

R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditio ns.
The recommended tyr epressures can be
found in th etable on the fuel filler flap.
The tyre pressure loss warning system can
only give reliabl ewarnings if you have set
the correct tyre pressure. If an incorrect
tyre pressure is set, these incorrec tvalues
will be monitored.

Important safet ynotes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operatin
gsituation
(Y page 399). Note that the correct tyre pres-
sure for the curren toperatin gsituation must
first be taught-in to the tyre pressure monitor.
If ther eisas ubstantial loss of pressure, the
warning threshold for the warning messag eis
aligned to the referenc evalues taught-in.
Restart the tyre pressure monitor after
adjustin gtothe cold tyr epressure
(Y page 403). Th ecurren tpressures are
saved as new referenc evalues. This will
ensure that awarning mess agewillonly
appear if the tyre pressure drops significantly.
The tyre pressure monitor doe snot warn you
of an incorrectly set tyr epressure. Observe
th en otes on the recommended tyr epressure
(Y page 399).
Th et yre press urem onitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object. In the

Th et yre pressure values indicated by the on-

The operation of the tyr epressure monitor
can be affecte dbyinterference from radio
transmitting equipment (e.g .radio head-
phones ,two-way radios) that may be being
operated in or near the vehicle.

RNING
Driving safety may be impaired if non-
approved parts ,tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
For this reason, Mercedes-Benz recommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle. H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
! Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
R doors
R doo rpillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carr yout
repairs or welding .You coul dimpair the
operatin gefficiency of th erestraint sys-
tems.
Hav eaccessories retrofitted at aqualified
specialist workshop.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been
specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Mercedes-Benz
accepts no responsibility for the use of parts
that have been independently or officially
approved.
In Germany, certain parts are only officially
approved for installatio normodification if
they comply with legal requirements. This
also applies to some other coun tries. All gen-
uine Mercedes-Benz part smeet the approval
requirements. The use of non-approved parts
may invalidat ethe vehicle' sgeneral operating
permit. 420
