WARNING
If you fit unsuitabl eaccessories onto tyre
valves, the tyre valve smay be overloadeda nd
malfunction, which can caus etyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can alsor esult in tyre pressure loss. There is a
risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
yourv ehicleonto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly ,the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in atyre
blow-out. There is arisk of accident.
R Check the tyre for foreig nobjects.
R Check whethe rthe whee lislosing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact aqualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
The recommende dtyre pressures for various
operating conditions can be found in the tyre
pressure table on the fuel filler flap
(Y page1 67).
Operation with an emergency spare wheel:
information on operation with an emergency
spar ewhee lcan be found in the genera lnotes in
the "Emergency spar ewheel" section
(Y page3 67).
Operation with atrailer: the applicable value
for the rear axle is the maximu mtyre pressure
valu estated in the table insid ethe fuel filler flap.
Additionally, the tyre pressure table may also
state tyre pressures for different loadc ondi-
tions. These are defined in the table as different numbers of passengers and amounts of lug-
gage .The actua lnumber of seats may vary ;for
more information, please refer to the vehicle's
registration documents.
If tyre sizes are not specified ,the tyre pressures
stated on the tyre pressure table apply for all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the fol-
lowing tyre pressure information is only vali dfor
that tyre size.
Use asuitable pressure gauge to check the tyre
pressure. The outer appearance of atyre does
not permi tany reliablec onclusion about the tyre
pressure. On vehicles fitted with the electronic
tyre pressure monitor, the tyre pressure can be checked using the on-board computer.
If possible,o nly correct tyre pressures when the
tyres are cold.
The tyres are cold:
R if the vehicl ehas been parked with the tyres
out of direct sunlight for at least three hours
and
R if the vehicl ehas not been drive nfurther than
1.6 km
Depending on the ambient temperature, the
vehicl espee dand the loadont he tyres, the tyre
temperature and thus the tyre pressure changes
by approximatel y10k Pa (0.1 bar/1.5 psi) per
10 †. Take this into account when checking the
pressure of warm tyres. Only correct the tyre
pressure 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 caus eincreased tyre damage
R have anegative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are minimu mvalues which offer you good ride com-
fort characteristics.
However, you can alsou se the values given for
higher loads. These are permissible and willn ot
adversely affect the running of the vehicle.
This does not apply to vehicles towing atrailer. Tyre pressure

ressure loss warning system
General notes While the vehicle is in motion
,the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in atyre. If the speed of rotation of
aw heel changes as aresult of aloss of pressure,
ac orresponding warning message will appear in
the multifunction display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active
Run Flat Indicator active
Restart with OK Restart with OK message which appears in
the Service
Service menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 358).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 356).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure 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 .Inthe event of
as udden loss of pressure, bring the vehicle to a
halt 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 (corner-
ing 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 vehi-
cle or on the roof).

the respective operating conditions. The rec-
ommended tyre pressures can be found in the

The tyre pressure loss warning system can
only give reliable warnings if you have set the correc ttyre pressure. If an incorrect tyre
pressure is set, these incorrect values will be
monitored.

ecombination
You can ask for information regarding permitted wheel-tyre combinations at aMercedes-Benz
Servic eCentre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle. These are specially adapted to the control
systems, such as ABS or ESP
®
and are
marked as follows:
R MO =Mercedes-Benz Original
R MOE =Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 =Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz.C ertain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with aload, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components.T his
could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from
any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz,s ince previ-
ous damage cannot alway sbedetected on
retreaded tyres. As aresult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tyres are fitted. Do not fit used tyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfor tisonp oor road surfaces. Roll comfort
and suspension comfor tare reduced and the
risk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommended tyre pressures can be found
in the tyre pressure table on the fuel filler flap.
For further information on tyre pressure, see
(Y page 356). Check tyre pressures regularly
and only when the tyres are cold. 366

mixed with additives recommended by
Mercedes-Benz.O bserve the instructions for
use in the product description. More informa- tion about recommended additives can be
obtained from any Mercedes-Benz Service

Mercedes-Benz recommends that you use fuel
brands that have additives.
The quality of the fuel available in some coun-
tries may not be sufficient. Residue could build
up in the fuel injection system as aresult. In this
