Only these tires allow driving safety systems such
as ABS and ESP
®
t
o also function optimally in win-
ter. These tires have been developed specically
for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteristics.
Observe the maximum permissible speed specied
for the M+S tires you have installed (/ page 255).
If you install M+S tires that have a lower maximum
permissible speed than the maximum design
speed of the vehicle, ax an appropriate warning
sign in the driver's eld of vision. You can obtain
this at a qualied specialist workshop.
Once you have installed the M+S tires, take the fol-
lowing measures:
R
check the tire pressure (/ page 244)
R
restart the tire pressure monitoring system
(/ page 250)
