tain characteristics, e.g. handling, vehic le
nois eemis sions or fuel consumption, may
otherwise be adv ersely affected. In addi-
tion, when driving with aload, tyr edimen-

!
Larg ewheels: the lower the section width
for acertain wheel size, the lower the ride
comfor tiso np oor roa dsurfaces. Roll com-
fort and suspensio ncomfort ar ereduced
and the risk of damage to the wheels and
tyres as aresult of driving over obstacles
increases.
Overview of abbreviations used in the follow-
ing tyr etables:
R BA: both axles
R FA: front axle
R RA: rear axle
You will find atable with recommended tyre
pressures for various operating conditions on
the inside of your vehicle's fuel filler flap. For
further information on tyre pressure, see
(Y page 399). Check tyre pressures regularly
and only when the tyres are cold.
Notes on the vehicle equipment –always fit
the vehicle:
R with tyre softhe sam esize on agiven axle
(left/right)
R with the same type of tyre satagiven time
(summer tyres, winter tyres, MOEx tended

Vehicles with MO Extended tyres are not
equippe dwithaTIREFIT kit at th efactory. It
is therefore recommended that you addition-
ally equip your vehicle with aTIREFIT kit if you
fit tyres that do no tfeature run -flat charac-
teristics, e.g. winter tyres. ATIREFIT kit can
be obtaine dfrom aqualified specialist work-
