is kept open continuously, which may lead to
air loss. G
WARNING
Should the tyre pressure drop repeatedly:
R chec kthe tyre for 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-Ben zisfitted on the tyre
valve.
Tyre pressures that are too low have anega-
tive effect on vehicle safety, which could lead
you to cause an accident.
If possible, only correct tyre pressures when
the tyres are cold. The tyres are cold when
the vehicle has been parked for at least three
hours or has been driven less than 1.5 km.
Depending on the ambient temperature, the
speed you are driving at and the load on the
tyres, the tyre temperature and thus the tyre
pressure may change by approximately
10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have anegative effect on handling charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. H
Environmental note
Check the tyre pressure regularly,atl east
every 14 days. Tyrep
ressur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational 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, acorresponding warning
message will appearint he multifunction dis-
play. G
WARNING
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning 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 object.
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 conditionsa re 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). 322

Important safety notes G
WARNING
Fuel is highly flammable. Fire, naked flames
and smokin gare therefor eprohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. G
WARNING
Do not come into contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you

Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with apetrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
For further information on refuelling and on
fuels, see (Y page 160).
Notes on fuel consumption The vehicle will use more fuel than usualin
the following situations:
R
at very low outside temperatures
R in urban traffic
R for short journeys
R when towing atrailer
R in mountainous terrain
i Only for certain countries: you can find
the current consumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY).T hese
documents are delivered with your vehicle.
The consumption figures are in each case
based on the currently applicable version.
R for vehicles up to the EURO 4standard
in accordance with EU Directive
RL 80 /1268 /EWG
R for vehicles complying with the EURO 5
standard or higher in accordance with
Regulation (EC) Nr. 715 /2007
Deviations from these values may occur
unde rnormal operating conditions.
! Do not use any fuel additives, as they can
cause malfunctions and engine damage. H

24-GHz radar sensor syste
m(coun try overview)
Th e24G Hz radar sensor system requires separate approval for each country. When you are
driving in acountry in whic hthe radar sensor system is no tapproved, you must deactivate
the system using the on-board computer (Y page 229). The currentcountry overview can be
obtaine dfrom aMercedes-Benz Service Centre.
Vehicles with anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities.
The currently active systems are automatically deactivated:
R DISTRONI CPLUS (Y page171)
R Blind Spot Assist (Y page196)
R PRE-SAFE ®
Brake (Y page45)
Ad isplay message appears in the multifunction display to tell you that the radar sensor system
is being switched off (Y page 245).
BA SP LUS (Y page 62) is the nalso unavailable.
If the deactivation does not occur automatically, you must deactivat ethe radar sensor system
using the on-board computer (Y page 229).
Vehicles withou tnavigation and vehicles for Australia: you must deactivate the radar
sensor system using the on-board computer whe nyou are near aradio telescope facility
(Y page 229).
