R When parking your vehicle, make sure that
the tyres do not ge tdeformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or simila releva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Maintenance and care of wheels and
tyres
Checking wheels and tyres
R Regularly chec kthe wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
crack sorseverecorrosion on wheels), at
least ever y14d ays, as well as after driving
off-road or on rough roads. Damaged
wheels can cause aloss of tyr epressure.
R Regu larly check th etyre tread depth and
the conditio nofthe tread across the whole
widt hofthe tyr e(Ypage 299). If neces-
sary, tur nthe front wheels to full lock in
orde rtoi nspect the inner sid eofthe tyre
surface.
R All wheels must hav eavalve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitorin gsystems) othe rthan
the standar dvalve cap or other valve caps
approved by Mercedes-Ben zfor your vehi-
cle.
R Regularly chec kthe pressur eofall the tyres
including the emergenc yspare wheel or the
spare wheel, particularly prior to long trips,
and correc tthe pressur easnecessary
(Y page 299). Ty

Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3mm.
Thus ,you should repl acet yres that have
insufficient tread.
R winter tyres sho uld bereplaced when the
trea ddepth is 4mmorl ess as they will no
longer provide adequat egrip.
R thet rea donat yre may not wear evenly.
Thus ,you should regularly chec kthe tread
depth and the condition of the tread across
the entire widt hofall tyres. If necessary,
turn the steerin gwheel so that you can see
the tyr etrea dm ore easily.
You coul dotherwise los econtrol of the vehi-
cle and cause an acciden tdue to the reduced
grip of the tyres on the road. Storing tyres
Store tyres that are not being used in acool,
dry and preferably dar kplace. Protect the
tyres against oil, grease, petrol and diesel. Cleaning tyres
! Do not use ahigh pressure jet with circu-
lar jet nozzles (concentrated-power jets) to
clean the tyres. The high pressure of the
water jet could damage the tyres. Always
replace damaged tyres. Tyr
epressures Recommended ty
repressures
You will find atable of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the
technical data section. Tyr

The tyre pressure values stored at the last
restart will continue to be monitored. Direction of rotation
Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergenc yspare wheel/spare
wheel against the direction of rotation.
Observe the tim erestric tion on use as well as
the speed limitation specified on the emer-
genc yspare wheel/spar ewheel. Interchanging th

Ris
kofa ccident
Interchange the front and rear wheels only if
they have the same dimensions: for example
size, offset, etc.
After every wheel interchange/change, have
the tightening torque checked at aqualified
specialist workshop that has the necessary
specialist knowledg eand tool stocarry out
the work required. Mercedes-Benz recom-
mends that you use aMercedes-Ben zService
Centr efor this purpose. In particular ,work
relevant to safet yoronsafety-related sys-
tems must be carried out at aqualified spe-
cialist workshop.
The wheel scould work loose if they are not
