Removing awheel !
Do no
tplace wheel bolts in sand or dirt. The
threads of the wheel bolts and wheel hubs
could otherwise be damagedw hen the bolts
are tightened.
When fitting/removing wheels, and for as long
as the wheels are removed, avoid applying any
external force on the brake discs. This could
impair the level of comfort when braking.
X Unscrew the wheel bolts.
X Remove the wheel.

WARNING
Oiled or greased wheel bolts/wheel nuts as
well as damaged wheel bolts/wheel nut
threads or wheel hub/wheel bolt threads
could cause the wheel bolts/wheel nuts to
loosen. As aresult, you coul dlose awheel
while driving. There is arisk of an accident.
Never oil or grease whee lbolts/wheel nuts. In
the event of damage to the threads, contact a
qualified specialist worksho pimmediately.
Have damaged whee lscrews/wheel nuts/

drain plug.
X Use the nuts to secure the faulty wheel to the
spare wheel bracket (Y page 223).
X Stow the jack and the vehicle tools in the
vehicle again.
X Check the tyre pressure of the newly fitted
wheel and adjust it if necessary.
Observe the recommended tyre pressure
(Y page 238). If you are drivin
gwith the emergency spare
wheel fitted, the tyre pressure monitor cannot
function reliably.R estart the tyre pressure mon-
itor only once the defective wheel has been
replaced with anew wheel.
All fitted wheelsm ust be equipped with func-
tioning sensors for the tyre pressure monitor. Wheel and tyre combinations
You can ask for information regarding permitted
wheel/tyre combinations at aMercedes-Benz
Service Centre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres, wheels and
accessories which have been approved by
Mercedes-Benz for you rvehicle. These are
speciall yadapted to the various driving safety
systems, such as ABS or ESP ®
.
Only use the tyres, wheels and accessories
tested and recommende dbyMercedes-Benz.
Certain characteristics, such as handling,
vehicl enoise emissions, fuel consumption,
etc. may otherwise be adversely affected.
Other wheel sizes may caus ethe tyres to
come into contact with the vehicl ebody and
axle components, whe nunder load. This may
result in damage to the tyre or the vehicle.
Mercedes-Benz is not responsibl efor any
damage caused by using tyres, wheels or
accessories other than those recommended.
Informatio nontyres, wheels and permissible
combinations can be obtained at aqualified
specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommende dbyMercedes-Benz, since previ-
ous damage cannot alwaysbed etected on
retreaded tyres. As aresult, Mercedes-Benz
cannot guarantee vehicl esafety if retreaded
tyres are fitted. Do not fit use dtyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Rol lcomfort
and suspension comfort are reduced and the risk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommende dtyre pressures for various
operating conditions can be found on the tyre 246
Wheel and tyre combinationsWheels and tyres
pressure table on the fuel filler flap. Further
information on tyre pressure (Y
page 238).
Check tyre pressures regularly and only when
the tyres are cold.
Notes on vehicle tyres:
R always fit the vehicle with tyres of the same
size on agiven axle (left/right)
R always fit the same type of tyres on your vehi-
cle at agiven time (summer tyres, winter
tyres, all-weather tyres, all-terrain tyres) Wheel and tyrec
