monito ractive display message is shown
instead of the tyre pressure display. The tyre
pressures are already being monitored.
If an emergency spare wheel is fitted, for a
few minutes the system may continue to
show the tyre pressure of the wheel that has
been removed. If this occurs, not ethat the
value displayed for the position where the
spare wheel is fitted is not the same as the
curren ttyre pressure of the emergency spare
wheel.
Warning messages of the tyr epressure
monitor If the tyre pressure monitor detects
apres-

sage is shown in the multifunction display and
the yellow tyre pressure monitor warning
lamp comes on.
R If the Please correc ttyre pressure
Please correc ttyre pressure
message appears in the multifunction dis- play, the tyre pressure in at least one tyre is
too low and must be corrected at the next
opportunity.
R If the Check tyre(s) Check tyre(s) message appears in
the multifunction display, the tyre pressure in one or more tyres has dropped signifi-
cantly and the tyres must be checked.
R If the Warnin gtyre defect
Warnin gtyre defect message
appears in the multifunction display, the
tyre pressure in one or more tyres has drop-

checked.
Observ ethe instructions and safety notes in
the display messages in the "Tyres" section
(Y page 322).
If the wheel position sonthe vehicle are inter-
changed, the tyre pressures may be displayed for the wrong position sfor as hort time. After
af ew minutes of driving, this is rectified and
the tyre pressures are displayed for the cor-
rect positions.
Restarting the tyr epressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
enc evalues for monitoring. In most cases, the
tyre pressure monitor will automatically
detec tthe new referenc evalues after you
have changed the tyre pressure. However,
you can also define referenc evalues man-
ually as described here. The tyre pressure
monitor then monitors the new tyre pressure values.
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operatin gconditions.
Also observe the notes in the section on
tyre pressures (Y page 420).

Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Observe the instructions and safety notes on "Changing awheel" (Y page 426).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz vehicles and the
respective wheel.
! AMG vehicles:

Mercedes-Ben
zrecommends that you use
fuel brands that have additives.
The quality of the fuel available in some coun- tries may not be sufficient. Residuec ould
build up in the injection system as aresult. In
this case, in consultation with aMercedes-
Benz Service Centre, the petrol may be mixed with the cleaning additive recommended by
Mercedes-Benz. Always observe the notes
and mixing ratios specified on the container.
Diesel Fuel grade
G
WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is arisk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalent quality. Fuel that does
not conformtoEN5 90 can lead to
increased wear as well as damage to the
engine and exhaust system.
! Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and
do not use any special additives. Other-
wise, engine damage may occur.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sul-
phur Euro diesel with asulphurc ontent of under 50 ppm
.Otherwise, the emission
control system could be damaged.
! Vehicles without
adiesel particle fil-
ter: in countries where only diesel fuel with
ah igh sulphurc ontent is available, you will
need to carry out your vehicle's oil change
at shorter intervals. More information
about the interval for oil change can be
obtained from any qualified specialist
workshop.
Usuallyy ou will find information about the
fuel grade on the pump. If you cannot find the
label on the petrol pump, ask the filling sta-
tion staff.
Information on refuelling (Y page 201).
Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc- tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be insufficient .Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climatic conditions.
i Further information on country-specific
fuel properties and fuel types with low-tem-
perature resistance can be obtained from
oil companies, e.g. at filling stations.
Fuel consumption information H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your vehicle's CO 2emissions are directly related to
fuel consumption and therefore depend on: 476
