A CI+ module (Common In terface Module),
which is not included in the scope of deliver y,is
used todecrypt HD prog rammes according to
th e CI+ standard. In some countries, an addi‐

cornering, when accelerating stronglyand
when braking. #
Do not exceed the permissible maxi‐
mum speed. #
Avoid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road).
This applies, in pa rticular, toa loaded

per form ance tyres
The special tyre tread in combination with
th e optimised tyre compound, means that
th erisk of skidding or hydroplaning on wet

Use M+S tyres at outside temp eratures
of less than 50 °F. Obse

R Countr y-specific requirements for tyre
appro valth at define a specific tyre type for

Fu rthermore, the use of cer tain tyre types in
cer tain regions and areas of operation can
be highly beneficial.
R Only use tyres and wheels of the same type
(summer tyres, winter tyres, MOEx tended
tyres) and the same make.
R Only fit wheels of the same size on one axle
(left and right).
It is only permissible tofit a di fferent wheel
size in theeve nt of a flat tyre in order to
