Remove the center wheel ornament by pushing from thereverse side.
Lay down the tire with the outer side facing up, and install the
holding bracket.
Then secure the tire, taking care that the tire goes straight up

ing valve and transmitter, low inflation pressure of the spare tire will not
be warned. Also, if you replace the temporary spare tire after the tire
pressure warning light comes on, the light remains on.
