Snow chains must not be fitted to emergency
spare wheels. General notes
You should regularly check the pressure of all
your tyres, including the emergenc yspare
wheel, particularly prior to long trips, and cor-
rect the pressure as necessary (Y page 331).
The applicabl evalue is found on the wheel or
under "Technical data" (Y page 354).
An emergenc yspare wheel may also be fitted
against the direction of rotation .Observe the
time restriction on use as well as the speed
limitation specified on the emergency spare

regardless of wear. This also applies to the
emergency spare wheel.
