Spare Tire Check
At least twice a year, after the monthly inflation check
of the spare tire determines that the spare is inflated to
the correct tire inflation pressure, make sure that the
spare tire is stored securely. Push, pull, and then
try

to tighten the cable. See Changing a
Flat Tire on page 5-71.

Silicone grease on weatherstrips will make them last

silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page
6-32.
Automatic Transmission Check
