Information on driving
R If the vehicle is heavily loaded, chec kthe
tire pressures and correct them if neces-
sary.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi- cate that the wheels or tires are damaged.If you suspect that atire is defective,
reduce your speed immediately. Stop the
vehicle as soon as possible to chec kthe
wheels and tires for damage. Hidden tire
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the wheels and tires checked at aqualified specialist workshop.

Observe the notes in the "Changing awheel"
section (Y page 270). Drivin
gwiths ummer tires
At temperatures below 45 ‡(+7† ), summer
tires experience aconsiderable loss in elas-
ticity and therefore traction and braking
power. Change the tires on you rvehicle to
M+S tires. Using summe rtires at very cold
temperatures coul dcause cracks to form,
thereb ydamaging the tires permanently.
Mercedes-Benz cannot accep tresponsibility
for this type of damage. M+S tires
G
WARNING
M+S tires with atire tread depth of less than
00CF in (4 mm )are not suitabl efor use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than 00CFin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7† ), use win-
ter tires or all-season tires. Both type softire
are identified by the M+S marking.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking pro-
vide the best possibl egrip in wintry road con-
ditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. Thi sisbecause
these tires were specifically developed for
driving in snow.
Use M+S tires of the same make and tread on
allw heels to maintain safe handling charac-
teristics.
Always observe the maximu mpermissible
spee dspecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
X Check the tire pressure s(Ypag e253).
X Restart the tire pressure monitor
(Y pag e259). 252

i Tire data is vehicle-specific and may devi-
ate from the data in the example.
General: depending on the manufacturer's
standards, the size imprinted in the tire wall
may not contain any letter sormay contain
one letter that precedes the size description.
If there is no letter preceding the size descrip-
tion (as shown above): these are passenger
vehicle tires accordin gtoEuropean manufac-
turing standards.
If "P" precedes the size description :these are
passenger vehicle tires accordin gtoU.S.
manufacturing standards.
If "LT" precedes the size description :these
are light truck tires accordin gtoU.S. manu-
facturin gstandards.
If "T" precedes the size description :these are
compact emergenc yspare wheels at high tire
pressure, to be used only temporarily in an
emergency.
Tire width: tire width0043shows the nominal
tire width in millimeters. Aspect ratio:
aspect ratio0044is the size ratio
between the tire height and tire width and is
shown in percent .The aspect ratio is calcu-
lated by dividing the tire width by the tire
height.
Tire code: tire code0087specifies the tire type.
"R" represent sradial tires; "D" represents
diagonal tires; "B" represent sdiagonal radial
tires.
Optionally, tires with amaximum speed of
over 149 mph (240 km/h) may have "ZR" in
the size description depending on the manu-
facturer (e.g. 245/40 ZR 18).
Rim diameter: rim diameter0085is the diam-
eter of the bead seat, not the diameter of the rim flange. The rim diameter is specified in
inches (in).
Load-bearing index: load-bearing index0083
is an umerical code that specifies the maxi-
mum load-bearing capacity of atire.
Do not overload the tires by exceeding the
specified load limit. The maximum permissi-
ble load can be found on the vehicle's Tire and
Loading Information placard on the B-pillar on the driver's side (Y page 260).
Example:
Load-bearing index 91 indicates amaximum
load of 1,356 lb (615 kg) that the tires can
bear. For further information on the maximum tire load in kilograms and lbs, see
(Y page 267).
For further information on the load bearing
index, see "Load index" (Y page 266).
Speed rating: speed rating0084specifies the
approved maximum speed of the tire.
Regardless of the speed rating, always
observe the speed limits. Drive carefully and
adapt your driving style to the traffic condi-
tions. Summer tires

Tire data is vehicle-specific and may devi-
ate from the data in the example.
In addition to the load-bearing index, load
index 0043may be imprinted after the letters
that identify speed rating 0084(Ypage 264) on
the sidewall of the tire.

R Light Load: represent salight load tire
R C, D, E: represent saload range that
depends on the maximum load that the tire can carry at acertain pressure
Maximum load rating Maximum tire load
0043is the maximum per-
missible weight for which the tire is approved.
Do not overload the tires by exceedin gthe
specified load limit. The maximum permissi-
ble load can be found on the vehicle's Tire and Loading Information placard on the B-pillar onthe driver's side (Y page 260).
i The actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
DOT, Tire Identification Number (TIN) U.S.t
ire regulations stipulate that every tire
manufacturer or retreader must imprint aTIN
in or on the sidewall of each tire produced. The TIN is
aunique identification number. The
TIN enables tire manufacturers to inform pur-
chasers of recalls and other safety-relevant
matters. It makes it possible for the pur-
chaser to easily identify the affected tires.
The TIN is made up of manufacturer identifi-
cation code 0044,tire size 0087,tire type code 0085
and manufacturing date 0083.
i Tire data is vehicle-specific and may devi-
ate from the data in the example.
DOT (Department of Transportation): tire
symbol 0043marks that the tire complies with
the requirement softhe U.S.D epartment of
Transportation.
Manufacturer identification code: manu-
facturer identification code 0044provides
details on the tire manufacturer. New tires
have acode with two symbols.
Tire size: identifier0087describes the tire size.
Tire typec ode:tire type code 0085can be used
by the manufacturer as acode to describe
specific characteristics of the tire.
Date of manufacture: date of manufacture
0083 provides information about the age of a
tire. The first and second positions represent the week of manufacture, starting with "01"
for the first calendar week. Positions three
and four represent the year of manufacture.
For example, atire that is marked with "3208"
was manufactured in week 32 in 2008. All about wheelsa
