f.
The cooling system requires adequate protection from extreme cold.
g.

and use.
2. Read and become familiar with the material in the referenced publications. They
cover information needed when operating a vehicle in extreme cold. Keep in mind
the problems characteristic of operation in cold weather, and ensure vehicle is
adequately prepared and protected for existing weather conditions. Follow these
guidelines when operating vehicle in conditions of extreme cold.
