ta ke regular breaks in good time that allow for
adequate recuperation.
Yo u can choose between two settings.
R Standard: normal sy stem sensitivity.

fi c situation and maintain a safe dis‐
ta nce at the side of theve hicle. Blind Spot Assist and
Active Blind Spot Assi st

cles and are no substitute for attentive driving.
Alw ays ensure that there is suf ficient di stance to
th e side forot her road users and obs tacles. Sy

tions:
R the sensors are dirty or co vered
R poor visibility, e.g. due tofog, heavy rain,
snow or spr ay
R narrow vehicles, e.g. bicycles, are within the
monitoring range
Wa rnings may be issued in er ror when driving
close tocrash ba rriers or similar solid lane bor‐

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
ro ads is inc reased.
In addition, the tyre grip is greatly reduced at
a low outside temp erature and tyre running
te mp erature. #
Switch on the ESP ®
and adapt your
driving style accordingly. #
Use M+S tyres at outside temp eratures
of less than 50 °F. Obse
rveth efo llowing when selecting, fitting and
re placing tyres:
R Countr y-specific requirements for tyre
appro valth at define a specific tyre type for
yo ur vehicle.
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
drive tothe specialist workshop.
R Only fit tyres of the cor rect size onto the
wheels.
R Do not make any modifications tothe brake
sy stem, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may in validate theve hicle's
