or more tires. The affected tire mus tnot show
any clearl yvisible damage.
You can recognize MOExtended tire sbythe
MOExtended marking which appears on the
sidewal lofthe tire .You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (
Ypage 330).
MOExtended tire smay only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure loss warnin gmessage appears

Driving with summe rtires
At temperatures belo w45‡(+7 †),summer
tire slos ee last icity and therefore tractio nand
braking power. Chang ethe tire sonyourvehicle to M+S tire
s. Usingsumme rtires at very cold
temperatures could cause cracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
GWARNING
Damage dtires can cause tire inflation pres-
sure loss. As aresult, you could lose control of
you rvehicle. There is arisk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with atire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provid esufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures belo w45‡ (+7 †), use winter
tires or all-season tires. Bot htype soft ire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibl egrip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in
winter. Theset ires have beend eveloped specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximu mpermissible
speeds pecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypag e322).
XRestart the tire pressure monitor
(Ypag e325).

The Tire and Loading Informatio nplacard is on
the B-pillar on the driver's side (
Ypage 326).
The Tire and Loading Informatio nplacard con-
tains the recommende dtire pressures for cold
tires. The recommende dtire pressures ar evalid
for the maximum permissibl eloa da nd up to the

Tire pressure table
The tire pressure table is on the insid eofthe fuel
fille rflap. It shows the tire pressure for al ltires
permitted at the factory for thisv ehicle; see
illustratio n(example).
The tire pressure table contains the recommen-
de dp ressures for col dtiresfor various operat-
ing conditions, i.e .differin gloa da nd spee dcon-
ditions.

Ypage 325).
Important safety notes
GWARNING
Each tire, including the spare (if provided),
shoul dbec hecked at least once every two
weeks when cold and inflated to the pressure recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver's door B-pillaro rthe tire pres-
sure label on the inside of the fuel fillerf lap. If
you rvehicle has tires of adifferent size than
the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label, you shoul ddetermine the
proper tire pressure for those tires.
As an adde dsafety feature, you rvehicle has
been equipped with atire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sure telltal ewhen one or more of you rtires
are significantly underinflated. Accordingly,
when the low tire pressure telltal elights up,
you shoul dstop and check you rtires as soon
as possible, and inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire cause sthe tire to overheata nd can
leadtot ire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that the TPMS is not asubstitute for proper tire
maintenance, and it is the driver's responsi-
bility to maintain correct tire pressure, even if
underinflation has not reached the level to
trigger illuminatio nofthe TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the sys-
tem detects amalfunction, the warning lamp
wil lflash for approximately aminute and then
remain continuously illuminated .This
sequence wil lberepeated every time the vehi-
cle is started as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be abl etodetect
or signal low tire pressure as intended.
TPMS malfunctions may occur for avariety of
reasons, including the installation of incom-
patibl ereplacement or alternate tires or
wheel sonthe vehicle that prevent the TPMS
from functioning properly. Alway scheck the
TPMS malfunction telltal eafter replacing one
or more tires or wheel sonyourv ehicle to
ensure that the replacement or alternate Tires
and wheelsa llow the TPMS to continue to
function properly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(
Ypage 319). Note that the correct tire pressure
for the current operating situation must first be
taught-in to the tire pressure monitor. If there is
as ubstantial loss of pressure, the warning
threshold for the warning messag eisaligned to
the reference values taught-in. Restart the tire
pressure monitor after adjusting the pressure of
the cold tires (
Ypage 325). The current pres-
sures are saved as new reference values. As a
result, awarning messag ewillappear if the tire
pressure drops significantly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the
notes on the recommended tire pressure
(
Ypage 319).
The tire pressure monitor is not abl etowarn you
of as udden loss of pressure, e.g. if the tire is
penetrated by aforeign object. In the event of a
su

dden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
movements.

monitor wil lautomatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can als odefine refer-
ence values manually as described here. The tire
pressure monitor then monitors the new tire
pressure values.

GWARNING
Overloade dtires can overheat, causing a

steering and driving characteristics and lead
to brake failure. There is arisk of accident.
Observet he loadrating of the tires. The load
rating must be at least hal fofthe GAWR of
you rvehicle. Never overload the tires by
exceeding the maximu mload.
Two instruction labels on you rvehicles how the
maximu mpossible load.
