WARNING
Shoul dthe tyr epressure dro prepeatedly:
R check the tyr efor foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only avalve cap approved
by Mercedes-Benz is fitted on the tyre
valve.
Tyre pressures that are too low have anega-
tiv ee ffect on vehicl esafety, which could lead
you to cause an accident.
If possible, only correc ttyre pressures when
the tyres are cold.
The tyres are cold:
R if the vehicl ehas been parked wit hthe tyres
out of direc tsunlight for at least three
hours and
R if the vehicle has not been driven further
than 1. 6km
Depe nding on the ambient temperature, the
speed you are drivin gatand the load on the
tyres, the tyre temperature and thus the tyre
pressure may chang ebyapproximately
10 kPa (0. 1bar/1 .5psi) per 10 †. Take this
int oa ccount whe nchecking the pressur eof
warm tyres and only correc titifitist oo low
for the curren toperating conditions.
Drivin gwith 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-
teristics and thus th edriving safet y(e.g. by
causin gaquaplaning)
i The tyr epressure values given for low
load sare minimum values which offe ryou
good rid ecomfort characteristics.
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.
You will find information on tyre pressures for
the vehicle's factory-mounted tyres on the
plates described here. Tyr
epressure loss warning system
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
WARNING
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. 360
