TIN (Tire IdentificationNumber)
Auniqu eide ntificatio nnumbe rwhich can be
used by atire manufacturer to identify tires, for
exampl efor ap roduct recall ,and thusi dentify
the purchasers. The TIN is compose dofthe
manufacturer identificatio ncode, tire size, tire
model cod eand manufacturing date.
Load bearin gind ex
The load bearing index (als oloa dindex) is acode
thatc ontains the maximu mloadb eari ng capa-
city of atire.
Traction
Tractio nist he resul toffrictio nbetween the tires
and the roa dsurface.

Wea rind icator
Narrowb ars( tread wear bars) thata redistrib-
ute doverthe tire tread. If the tire trea dislevel
with the bars, the wear limit of áin (1.6 mm)
hasb eenr eached.

Changing wheels
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severelyi mpair the driving characteristics if
the wheels or tires have different dimensions. The whee lbrakes or suspension components
may als obedamaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equippedw ithatire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve .This could damage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Always observe the instructions and safety
notes under "Mounting awheel" (
Ypage 287).
The wea rpatterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wea rpattern
has formed on the tires. Front tires typically
wea rmore on the shoulders and the rear tires in
the center.
If you rvehicle's tire configuration allows, you
can rotate the wheels according to the intervals
in the tire manufacturer's warranty book in your
vehicled ocuments. If no warranty book is avail-
able, the tires should be rotated every 3,000 to
6,000 mile s(5,000 to 10,000 km) or earlier if
tire wea rrequires. Do not change the direction
of rotation.
Clean the contact surfaces of the whee land the
brake disc thoroughly every time awheelisr ota-
ted. Avoid oily or greas ycleaning agents.
Check the tire pressure and reactivate the tire
pressure monitor if necessary.
Directio nofrotation
Tires with aspecified directio nofrotation have
additional benefits, e.g. if there is arisk of hydro-
planing. You wil lonly gai nthese benefits if the
correct directio nofrotation is observed.
An arrow on the sidewal lofthe tire indicates its
correct directio nofrotation.
You may mount aspare whee lagainst the direc-
tion of rotation. Observe the time restriction on
use as wel lasthe speed limitation specified on
the spare wheel.
Storing wheels
Store wheels that are not being used in acool,
dry and preferably dark place. Protect the tires
from contact with oil, greas eand fuel.

Additives
!Do notuse any additive sintheengin eoil.
This could damag ethe engine.
Engineo il viscosity
!If theSAE viscosit yclassoft heengin eoil
used does no tcover th eoutside temperature
range in whic hyou are operating th evehicle,
it mus tbechanged in goo dtime, in particular
before th ecolds eason commences. Using an
engin eoil that does no thavea dequate tem-
peratur echaracteristics can lead to engin e
damage.
The temperature range information of th eSAE
classification always refers to that of fresh oil.
The temperature characteristics of th eengine
oil may deteriorat esignificantly due to agin g
in use, especially at low outside tempera-
tures.
We recommen dthaty ou chang ethe engin e
oil before th ecolds eason commences. Use
an approve dengineo il of th especifie dSAE
class.

Viscosit yindicates th eflowc haracteristics of a

Dependin gontherespective outside tempera-

classification (viscosity). The table displays th e

regular oil changes usin ganapprove dengineo il

recommended.
Oil change
Oil chang eintervals depend on th evehicle's
operating condition sand th equalit yoft he

matically shows th edatef or th enexto il chang e
as an event message in th edisplay.
Mercedes-Benz recommends having th eoil
changed at aqualified specialist workshop .
Information abou toil consump tion
Dependin gonthedrivin gstyle, th evehicl econ-
sumes amaximum of 1. 0USqt(1.0l )ofe ngine
oil over adistance of 620 miles (1,000 km).
Oil consumption may be higher if:
Rthe vehicle is new.
Ryou mainly operate the vehicle under arduous
operating conditions.
Ryou frequently drive at high engine speeds.
Regularm aintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven aconsiderable distance.
Check the engine oil level on aregular basis, e.g.
weekly or each time you refuel (
Ypage 242).
