lar-jet nozzles (dirt grinders) to clean your
vehicle ,inparticular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Always maintain adistance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correc tdistanc eisavailable from the
equipment manufacturer.
Move the high-pressure cleane rnozzle
around when cleanin gyour vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, join tsetc.

can lead to leaks or failures.
Cleanin gthe paintwork !
Do not affix:
R stickers
R films
R magnetic plate sorsimilar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit aqualified spe-
cialist workshop. X
Remove impurities immediately, where
possible, whils tavoiding rubbing to ohard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with acloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remov etar stains.
X Use silicone remover to remove wax.
Care and treatment of mat tpaintwork !
Never polis hthe vehicle or the light alloy
wheels. Polishin gmakes the paintwork
shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitable mate-
rials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or glos spreserver, e.g.
wax .These product sare onl ysuitable for
high-glos ssurfaces. Thei ruse on vehicles
wit hm att finish leads to considerable sur-
face damage (shiny, spotted areas).
Always have paintwork repairs performed
at aq ualified specialist workshop, e.g. a
Mercedes-Ben zService Centre.
! Do not use wash programs with ahot wax
treatmen tunder any circumstances.
Observe thes enotes if your vehicle has a
clea rmatt finish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.
Thes enotes also apply to light-alloy wheels
with aclear matt finish. 368

wheel (Y page 414). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or mor etyres.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning syste morwith an activ etyre pres-
sure monitor and on wheels specificall ytes-
ted by Mercedes-Ben z.
No tes on driving with MOExtended tyres with
af lat tyre (Y page 378).
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory.
It is therefore recommended that you addi-
tionally equi pyour vehicle with aTIREFIT kit
if yo ufit tyres that do not featur erun-flat
characteristics, e.g. winter tyres. ATIREFIT
kit can be obtaine dfrom aqualified spe-
cialist workshop. Winter operation
General notes
Have your vehicle winterproofed at aqualified
specialist worksho patthe onset of winter.
Observ ethe notes in the "Changin gawheel"
section (Y page 404). Driving wit
hsummer tyres
At temperatures belo w+7† ,summer tyres
lose elasticity and therefore traction and
braking power. Change the tyres on your vehi-
cle to M+S tyres .Using summer tyres at very
cold temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility
for this typ eofdamage. M+S tyres
G
WARNING
M+S tyres with atyre tread depth of less than
4mma re not su itable for use in winter as they
do not provid esufficient traction. There is a
risk of accident.
M+S tyres with atrea ddepth of less than
4mmm ust be replaced.
At temperatures below +7 †, use winter tyres
or all-seas ontyres.B oth types of tyr eare
identified by th eM+S marking.
Onl ywinter tyres bearing the isnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintr yroad con-
ditions.
Only these tyres will allow drivin gsafety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. Thes etyres have been devel-
ope dspecifically for driving in snow.
Use M+S tyres of the same mak eand tread
on all wheels to maintain safe handling char-
acteris tics.
Alway sobserv ethe maximum permissible
speed specifie dfor the M+S tyres you have
fit ted.
If you fit M+S tyres that have alower maxi-
mu mp ermissible speed than that of the vehi-
cle, affix acorresponding warnin glabel in the
driver' sfield of vision. This can be obtained
at aq ualified specialist workshop.
Under these circumstances, you should also
restrict the maximum spee dofthe vehicle
usin gpermanen tSPEEDTRONIC so that it
does not exceed the maximu mpermissible
speed for the M+S tyres(Y page 198).
When you have fit tedt he M+S tyres:
X Chec kthe tyr epressures (Y page 399).
X Restart th etyre pressure monitor
(Y page 403).
X Restart the tyre pressure los swarning sys-
tem (Y page 401).

re pr essur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warnin gsystem monitors the set
tyre pressure using the rotational speed of
the wheels. This enable sthe system to detect
significant pressur eloss 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.
The tyr epressure warning system does not
warn yo uofani ncorrectly set tyre pressure.
Observe the notes on the recommended tyre
pressure (Y page399).
Th et yre pressure los swarning 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 objec t. Inthe
event of asudden loss of pressure, bring the
vehicle to ahalt 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 (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).
Resta rting the ty re pressur eloss warn-
ing system Restart the tyre pressure loss warnin

if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditio ns.
The recommended tyr epressures can be
found in th etable on the fuel filler flap.
The tyre pressure loss warning system can
only give reliabl ewarnings if you have set
the correct tyre pressure. If an incorrect
tyre pressure is set, these incorrec tvalues
will be monitored.
