Refer to following for maintenance under unusual conditions before operating vehicle:
Table 2-1 for PMCS.
Paragraph 3-14 for maintenance under unusual conditions.

2-16. UNUSUAL ENVIRONMENT/WEATHER CONDITIONS.
Extreme Cold Weather Conditions.
Extreme cold weather causes oil to thicken, insulation to crack, materials to become brittle and break, and
batteries to freeze. Because of these and other problems the vehicle will be more difficult to operate.
Armament used in extreme cold weather operations must be properly lubricated. Vision devices must not
be moved suddenly from warm to cold or cold to warm areas. Condensation may cause clouding of lenses
and rusting of internal parts. Do not breathe on lenses.
Refer to and study information in FM 31-70, FM 31-71, and FM 9207. This information is necessary for
effective operation of vehicle during cold weather.
