Extreme cold causes many problems:
(a)
Lubricants thicken or congeal.
(b)
Batteries may freeze or lose their electrical efficiency.
(c)

(d) Various materials will become hard, brittle, and easily
damaged.
extreme cold.
(e) The cooling system requires adequate protection from
(f) Fuels, lubricants, and antifreeze compounds require

Winterization Kit. All vehicles assigned to arctic regions are
equipped with a winterization kit which protects vehicle systems from freeze damage
and enables easier starting.
(4)
Starting Out.
(a) Be careful when you first start your vehicle. Use cold
weather starting procedure (paragraph 2-14) and allow engine time to reach operat-
ing temperature range of 120-140°F (48-59°C). Be alert that tires may be frozen to
ground.
(b) Start driving very slowly for about 100 yards (91.4 m).
Be alert for signs that tires may have flat spots or that one or more brake shoes may
be frozen and require preheating. Notify Unit Maintenance as required.

If vehicle will be parked for a short period, park in a shel-
tered area out of wind. If shelter is not available, park vehicle so it does not face into
the wind.
(b)
If vehicle will be parked for a long shutdown period, try
to park on high ground and use planks or brush to make a raised and relatively dry
surface. Keep tires out of snow, water, ice, and mud, if possible.
(c)
Clean snow, ice, and mud from vehicle as soon as pos-
sible after shutdown.
(d)
If vehicle will be parked for a long period of time, have
