OPERATION UNDER UNUSUAL CONDITIONS - CONTINUED
OPERATE IN EXTREME COLD - CONTINUED
Operate Arctic Heater (If Equipped).
DO NOT operate arctic heater in a confined area. Always ensure there is adequate fresh air ventila-
tion. Failure 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 tempera-
tures below -25F (-32C). 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 con-
tinuous high engine RPM and continuous operation in soft terrain.
a. Check water temperature display and stop if temperature is unusually high. Allow vehicle to cool down.
b. 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.
c. Notify Organizational Maintenance to shorten differential oil change interval.
a. Park vehicle under cover, if possible. If shelter is not available, cover vehicle with tarpaulins. If there aren't 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 sandblasting.
b. Ensure all tires are inflated to proper pressure.
c. Check frequently for rust. Clean and lubricate vehicle to help prevent deterioration.
OPERATE IN MUD OR SOFT SURFACES
Before driving in mud or other soft surfaces, select appropriate transmission gear range. Use 4-wheel drive as required.
Enter soft area at a medium speed for gear range selected. Avoid oversteering, if possible, while driving in mud.
Maintain steady pressure on accelerator pedal to keep vehicle rolling until solid ground is reached. DO NOT accelerate
to point where wheels spin, if possible.
If vehicle gets stuck, shovel a clear path ahead of each tire and try to drive out slowly in a low gear. Boards, brush, or
similar materials may be placed under tires to provide traction.
Maintain steady, even movement with transmission in lower gears. Use 4-wheel drive as required. Try to keep vehicle
rolling without straining engine and powertrain. If vehicle gets stuck, notify Organizational Maintenance.
If these efforts fail and it becomes evident that vehicle will not free itself, notify Organizational Maintenance.
Clean and inspect propeller shafts for proper lubrication.
