could become trapped if their limbs are
between theve hicle body and the tyres or
underneath theve hicle. #
Make sure no one is underneath the

Driving and parking

If
th e tyre's maximum speed is below that of
th eve hicle, this must be indicated byan
appropriate label in the driver's field of
vision.
R Run in new tyres at moderate speeds forthe
fi rs t10 0 km.
R Replace the tyres af ter six years at the latest,
re ga rdless of wear.
R When replacing with tyres that do not
fe ature run-flat characteristics: vehicles
with MOExtended tyres are not equipped
with a TIREFIT kit at thefa ctor y.Equip the
ve hicle with a TIREFIT kit af terre placing with
tyres that do not feature run-flat characteris‐
tics, e.g. winter tyres.
% You can permanently limit the maximum
ve hicle speed for driving with winter tyres
(/ page 203).
Fo r more information on wheels and tyres, con‐
ta ct a qualified specialist workshop.

WARNING Risk of injury thro ugh dif fer‐
ent wheel sizes
Inter changing the front and rear wheels can
se verely impair the driving characteristics.
The disk brakes or wheel suspension compo‐
nents may also be damaged. #
Onlyinter change the front and rear
wheels if the wheels and tyres ha vethe
same dimensions. Inter
changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions can
re nder thege neral operating pe rmit in valid.
The wear pat tern s on the front and rear wheels
dif fer:
R front wheels wear more on the tyre shoulder R
rear wheels wear more in the cent reofthe
tyre
Do not drive wi thtyres that ha vetoo little tread
dep th. This significantly reduces traction on wet
ro ads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for
th e wheels.
Obser vethe instructions and saf ety no tes on
