Warning
Af lat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is arisk of an accident.
Do not drive with aflat tyre. Immediately
replace the flat tyre with yours parew heel, or
consult aqualified specialist workshop.
Accessorie sthat are not approved for yourv ehi-
cle by Mercedes-Benz or are not being used cor- rectly can impair the operating safety.
Before purchasing and using non-approved
accessories, visit aqualified specialist work-
shop and enquire about:
R suitability
R lega lstipulations
R factory recommendations
Further information regarding wheels and tyres
can be found under "Wheel/tyre combinations"
(Y page2 46).
You can ask for information regarding permitted
wheel/tyre combinations at aMercedes-Benz
Service Centre. Information on tyre pressure can be found:
R on the tyre pressure table in the fuel fille rflap
(Y page 109)
R under "Tyre pressure" (Y page 238)
Modification work on the brake system and
wheelsisn ot permitted, nor is the use of spacer
plates or brake dust shields. This invalidates the general operating permit for the vehicle.

At temperature sbelo w+ 7† ,summer tyres lose
elasticity and therefore traction and braking
power. Change th etyres on your vehicle to
M+ Styres. Using summer tyres at ver ycold
temperature scould cause tears to form,
thereby damagin gthe tyres permanently.

G
WARNING
M+S tyres with atyre tread depth of less than
4mma re not suitable for use in winter as they
do not provid esufficient traction. There is a
risk of accident.
M+S tyres with atread depth of less than
4mmm ust be replaced. G
WARNING
The whee lortyre size as wellast he tyre type
of the spar ewhee land the whee ltobe
replaced may differ .Driving characteristics
can be severely impaired when you fit the
spar ewheel. There is arisk of an accident.
To prevent risks:
R adapt yourd riving style accordingly and
drive carefully
R never fit more than one spar ewhee lthat
differ sfrom the whee ltobechanged
R only use aspar ew hee lthat differ sfrom the
whee ltobec hanged for abriefp eriod
R do not switch ESP ®

R have aspar ew hee lofad ifferent size
replaced at the neares tqualified specialist
workshop. You must make sure that the wheel and tyre dimensions as wel
lasthe

Do not exceed amaximum speed of 80 km/h if
as pare wheel of adifferen tsizeisf itted.
At temperatures below +7 †, use winter tyres or all-season tyres. Bot htypes of tyr eare identified
by th eM+S marking.
Only winter tyres bearin gthe i snowflake
symbo linaddition to th eM+S marking provide
th eb est possible grip in wintry road conditions.
Only these tyres will allow driving safet ysys-
tem ssuch as AB Sand ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of th esame mak eand tread on all
wheels to maintain safe handling characteris-
tics.
Always observe th emaximum permissible
speed specified for th eM+S tyres you have fit-
ted.
If you fit M+S tyres that have alower maximum
permissible speed than that of th evehicle, affix
an appropriat ewarning label in th edriver's field
of vision. This can be obtained at aqualified
specialist workshop.
When you have fitted th eM+S tyres:
X Chec kthe tyrep ressures (Y page 238).
X Restart th etyrep ressure monitor

WARNING
If you drive too fas twith snow chains fitted,
they may snap. As aresult, you coul dinjure
others and damage the vehicle. There is arisk

You can fin dinformation on what to do in the
event of aflat tyr eunder "Breakdown assis-
tance" (Y page 224). Interchanging th
ewheels G
WARNING
Interchangin gthe front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The whee lbrakes or suspension components
may alsobed amaged. There is arisk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with
atyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be appliedint he
area of the valve ,asthis coul ddamage the
electronic components.
Only have tyres changed at aqualified spe-
cialist workshop.
Interchanging front and rear wheels of differing
dimensions can render the genera loperating
permi tinvalid.
Always pay attention to the instructions and
safety notes under "Changing awheel"
(Y page2 43). The wear patterns on the front and rear tyres
diffe
rdepending on the operating conditions.
Interchange the wheels before aclear wear pat-
tern has formed on the tyres. Frontt yres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,00 0kmd epending on the
degree of tyre wear. Ensure that the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time awheel is
interchanged. Check the tyre pressure and reac-
tivate the tyre pressure monitor if necessary
(Y page 241). Direction of rotation
Tyres with aspecifie ddirection of rotation have
additional benefits, e.g. if there is ariskofa qua-
planing. You will only gain these benefit sifthe
correc tdirection of rotation is observed.
An arrow on th esidewall of th etyrei nd icates its
correc tdirection of rotation.
You may fit th espar ewhee lagainst th edirection
of rotation .Observ ethe time restriction on use
as well as th espeed limitation specifie donthe
