You should regularl ycheck the pressure of
the emergency spare wheel, particularl yprior
to long trips, and correct the pressure as
necessary (Y page338). The applicable value
is found on the whee lorunder "Technical
data "(Ypage3 70).
An emergency spare whee lmay alsobe
mounted against the direction of rotation.
Observe the time restriction on use as wellas
