PSI
(pounds persquar einch)
A standard unitofmeasure fortire pressure.
Aspect ratio
Relationship betweentireheight andtirewidth

Tire pressur e
This ispressure insidethetire apply inganout-
ward force toeach square inchofthe tire's sur-
face. Thetirepressure isspecified inpounds per
square inch(psi), inkilopascal (kPa)orinbar.
The tirepressure shouldonlybecorrect edwhen
the tires arecold.
Cold tirepressur e
The tires arecold:
R ifthe vehicle hasbeen parked withthetires
out ofdirect sunlight foratleast three hours
and
R ifthe vehicle hasnotbeen driven further than
1 mile (1.6km)
Tread
The part ofthe tire that comes intocont actwith
the road.
Bead The tirebead ensures thatthetire sits securely

TIN (Tire Identification Number)
This isaunique identifier whichcanbeused by
a tire manufacturer toidentify tires,forexample
for aproduct recall,andthus identify thepur-
chasers. TheTINismade upofthe manufactur-

Changing
awheelWheels andtires

Tire-mount

the valve. Thiscould damage theelectron ic
compon ents.
Only have tireschanged ataqualified spe-
cialist workshop.
Observe theinstr uctions andsafety notesinthe
"Changing awheel" section (Ypage 310).
The wear pattern son the front andrear tires
differ, depending onthe operating conditions.
Rotate thewheels beforeaclear wearpattern
has formed onthe tires. Fronttires typically
wear more onthe shoulders andtherear tires in
the cent er.
On vehicles thathave thesame sizefront and
rear wheels, youcan rotat ethe wheels accord-
ing tothe inter valsinthe tire manufact urer's
warranty bookinyour vehicle document s.Ifno
warranty bookisavailabl e,the tires should be
rotat edevery 3,000 to6,000 miles(5,000 to
10,00 0km ).Dependin gon tire wear, thismay
be required earlier.Donot change thedirection
of wheel rotation.
Clean thecont actsurfaces ofthe wheel andthe
brake discthoroughly everytimeawheel isrota-
ted. Check thetire pressure and,ifnecessary,
restart thetire pressure losswarning system
(Canada only)orthe tire pressure monitor(USA
only). Direction
ofrota tion
Tires withaspecified directionofrotat ionhave
additional benefits,e.g. ifthere isarisk ofhydro-
planing. Theseadvantages canonly begained if
the tires areinstalled correspon dingtothe
direction ofrotat ion.
An arrow onthe sidewall ofthe tire indicates its
correc tdirection ofrotat ion. Storing

Raising thevehicle G
WARNING
If you donot position thejack correct lyat the
appropriate jackingpoint ofthe vehicle, the
jack could tipover withthevehicle raised.
There isarisk ofinjury.
Only position thejack atthe appropriate jack-
ing point ofthe vehicle. Thebase ofthe jack must
bepositioned vertically,directlyunder
the jackin gpoint ofthe vehicle.
! Only
position thejack atthe appropriate
jackin gpoint ofthe vehicle. Otherwise, you
could damage thevehicle.
Observe thefollow ingwhen raising thevehi-
cle:
R To raise thevehicle, onlyusethevehicle-spe-
cific jack thathasbeen tested andapproved
by Mercedes-B enz.Ifused incorrec tly,the
jack could tipover withthevehicle raised.
R The jack isdesigned onlytoraise andhold the
vehicle forashort timewhile awheel isbeing
changed. Itmust notbeused forperforming
maintenan cework under thevehicle.
R Avoid changing thewheel onuphill anddown-
hill slopes.
R Before raising thevehicle, secureitfrom roll-
ing away byapply ingthe parking brakeand
insertin gwheel chocks.Do not disengage the
parking brakewhilethevehicle israised.
R The jack must beplaced onafirm, flatand
non- slipsurface. Onaloose surface, alarge,
flat, load-bearing underlaymustbeused. Ona
slippery surface, anon- slipunderlay mustbe
used, e.g.rubber mats.
R Do not use wooden blocksorsimilar objects
as ajack underlay. Otherwise, thejack willnot
be able toachieve itsload-bearing capacity
due tothe restrict edheight.
R Make surethatthedistance between the
underside ofthe tires andtheground doesnot
exceed 1.2in(3 cm).
R Never placeyourhands andfeet under the
raised vehicle.
R Do not lieunder thevehicle.
R Do not start theengine whenthevehicle is
raised.
R Do not open orclose adoor orthe trunk lid
when thevehicle israised.
R Make surethatnopersons arepresent inthe
vehicle whenthevehicle israised. 312
