Snow chains may be fitted on ly to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on whic h tire sizes
snow chains can be used.
I f you are going to use snow chains , then you
must install them on the front wheels at

dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions .
([) Note
-Remove snow cha ins before driving on
roads not covered with snow to avoid
damaging t ires and wear ing the snow
