OPERATE IN EXTREME COLD - CONTINUED
(1) If vehicle will be parked for a short period, park in a sheltered area out of wind. If shelter is not available, park
vehicle so right side, where radiator is located, does not face into the wind.
(2) 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.
(3) Clean snow, ice, and mud from vehicle as soon as possible after shutdown.
(4) If vehicle will be parked for a long period of time, have Organizational Maintenance remove and store batteries.
Fill fuel tank to guard against condensation and drain any accumulated water from air reservoirs and fuel filters.
(5) Ensure tires are properly inflated.
2.
Operate Arctic Heater (If Equipped).
WARNING
DO NOT operate arctic heater in a confined area. Always ensure there is adequate fresh air ventilation. Fail-
ure to follow this warning may cause death due to carbon monoxide poisoning.
NOTE
• Arctic heater is used to provide engine preheating for engine startup in extreme cold, in temperatures below
-25°F (-32°C). When heater is required to preheat engine coolant and engine block before startup, it should
be turned on 3/4 hour before engine is started.
• Operating instructions for the arctic heater will be provided with the arctic heater installation kit.
OPERATE IN EXTREME HEAT
1.
General. During very hot weather, driving procedures may require altering to prevent vehicle overheating. Avoid contin-
uous high engine RPMs, and continuous operation in soft terrain.
2.
