!Please compare the recommended tire
inflation pressure for your vehicle with
the tire inflation pressure on the yellow
label located on the spare wheel rim.
If the tire inflation pressure on the yel-
low label on the spare wheel rim differs
from the values given in this Operator’s
Manual, inflate the spare wheel tire to
the recommended tire inflation pres-
sure given on the yellow label on the
spare wheel rim.
iPlease note that the tire inflation pres-
sure of the Minispare tire differs from
the tire inflation pressure of the road
tires.
Make sure the Minispare tire is inflated
to approximately 60 psi (4.1 bar).
