ynotes
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows, all the compo-
nen tson th ecircuit and their function swill
fail. G
Ris
koff ire
Only use fuses that have been approve dfor
Mercedes-Ben zvehicles and which have the
cor rect fuse rating for the systems con-
cerned. Do not attempt to repai rorbridge
faulty fuses .Otherwise, acircuit overload
could cause afire. Have the cause traced and
rectified at aqualified specialist workshop,
e.g. aMercedes-Benz Ser vice Centre. Blow
nfuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart .AMercedes-
Ben zService Cent rewill be happy to advise
you.
If the newly inserted fuse also blows, have the
cause traced and rectified at aqualified spe-
cialist workshop, e.g. aMercedes-Benz
Ser vice Centre.
! Onlyuse fuses that hav ebeen approved
for Mercedes-Ben zvehicles and which

X Remove the key from the ignitio nlock.
The fuses ar elocated in variou sfuse boxes:
R fuse box on the driver' sside of the dash-
board
R fuse box in the engin ecompartmen tonthe
driver's side
R fuse box in the boot on the right when
viewed in the direction of travel

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
gsystem
if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the insid eofthe fuel filler flap
to ensur ethat the tyr epressure in all four Tyre pressures
