Risk of accident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving stability
will be impaired owing to unstable cornering
characteristics caused by the different tyres.
You should therefore adapt your driving style
and drive carefully.
Have the spare wheel* replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at a quali-
fied specialist workshop.
Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding
standard of quality.
! Do not drive in ADS SPORT mode when
driving with snow chains fitted.
If you intend to fit snow chains, please bear
the following points in mind:
you may not attach snow chains to all
R
wheel-tyre combinations; see the "Tyres
and wheels" section in the "Technical data"
chapter.
snow chains must not be fitted to emer-

ing on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
Shift the selector lever to N.
