Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. (See “Recommended Fluids and Lubricants”
in the Index.)
Automatic Transmission Check
Check the transmission fluid level; add if needed.
See “Automatic Transmission Fluid” in the Index.
A fluid loss may indicate a problem. Check the system
and repair if needed.
