OPERATION UNDER UNUSUAL CONDITIONS - CONTINUED
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.
Operate Arctic Heater (If Equipped).
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.
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
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.
Check water temperature display and stop if temperature is unusually high. Allow vehicle to cool down.
Check cooling system, air cleaner, air cleaner restriction indicator, engine oil level, and radiator fins frequently. Per-
form necessary services and notify Organizational Maintenance of any unusual readings or problems.
Notify Organizational Maintenance to shorten differential oil change interval.
Park vehicle under cover, if possible. If shelter is not available, cover vehicle with tarpaulins. If there arent enough
tarps to cover entire vehicle, arrange tarps around engine compartment and over radiator to keep sand and dust out.
Cover window glass to protect against sand blasting.
Ensure all tires are inflated to proper pressure.
Check frequently for rust. Clean and lubricate vehicle to help prevent deterioration.
OPERATE IN MUD OR SOFT SURFACES
Before entering mud or other soft surfaces, check conditions and select appropriate transmission gear range. Use four-
wheel drive as required. Enter soft area at a medium speed for gear range selected.
