OPERATION

All Wheel Drive (AWD)

Press the top of the rocker switch to engage All Wheel Drive (A WD). The illuminated amber AWD switch indicates that the vehicle is in AWD.

When the AW D switch is on, the front gearcase will automatically engage any time the rear wheels lose traction. When the rear wheels regain traction, the front gearcase will automatically disengage. There is no limit to the length of time the vehicle may remain in AWD.

Tip: The AWD switch may be turned on or off while the vehicle is moving.

Initially, the vehicle's electronic system will not enable the AWD until the engine RPM is below 3100. Once enabled, the AWD remains enabled until the AW D switch is turned off.

Engage the AWD before getting into conditions where front wheel drive may be needed. If the rear wheels are spinning, release the throttle before switching to AWD.

NOTICE: Switching to AWD while the rear wheels are spinning may cause

severe drive shaft and clutch damage. Always switch to AWD while the rear wheels have traction or are at rest.

Disengaging AWD

Move the AWD switch to the center or bottom position to disengage AWD.

If the switch is turned off while the front gearcase is moving, it will not disengage until the rear wheels regain traction.

In some situations, the front gearcase may remain locked after turning the AW D switch off. If this occurs, you may notice increased steering effort and some vehicle speed restriction. Perform the following procedure to unlock the front gearcase.

1. Stop the vehicle.

2. Operate in reverse for at least 10 feet (3 m).

3. Stop completely.

4. Shift into low gear and drive forward.

5. If the front gearcase remains locked after following these instructions, return the vehicle to your dealer for service.

Spark Plugs

Spark Plug Inspection

Normal Plug

The normal insulator tip is gray, tan or light brown. There will be few combustion deposits. The electrodes are not burned or eroded. This indicates the proper type and heat range for the engine and the service.

The tip should not be white. A white insulator tip indicates overheating, caused by use of an improper spark plug or incorrect carburetion adjustments.

Wet Fouled Plug

The wet fouled insulator tip is black. A damp oil film covers the firing end. There may be a carbon layer over the entire nose. Generally, the electrodes are not worn. General causes of fouling are excessive oil, use of non-recommended oil, improper use of the chok e, or incorrect throttle body/carburetor adjustments.

MAINTENANCE

Cooling System

The engine coolant level is controlled or maintained by the recovery system. The recovery system components are the overflow bottle, radiator filler neck, radiator pressure cap and connecting hose.

As coolant operating temperature increases, the expanding (heated) excess coolant is forced out of the radiator, past the pressure cap, and into the overflow bottle. As engine coolant temperature decreases, the contracting (cooled) coolant is drawn back up from the tank, past the pressure cap, and into the radiator.

Some coolant level drop on new vehicles is normal as the system is purging itself of trapped air. Observe coolant levels and maintain as recommended by adding coolant to the overflow bottle.

MAINTENANCE

Cooling System

Adding or Changing Coolant

To ensure that the coolant maintains its ability to protect the engine, we recommend that the system be completely drained every two years and a fresh mixture of antifreeze and water added. Polaris recommends the use of Polaris Premium 60/40 anti-freeze/coolant or a 50/50 mixture of high quality aluminum compatible anti-freeze/coolant and distilled water. Polaris Premium 60/40 is already premixed and ready to use. Do not dilute with water. See page 100 for the part numbers of Polaris products.

Always follow the manufacturer's mixing recommendations for the freeze protection required in your area.

Any time the cooling system has been drained for maintenance or repair, replace the coolant. If the recovery bottle has run dry, the level in the radiator should be inspected. Add coolant as needed.

Radiator and Cooling Fan

Always check and clean the screen and radiator fins at the intervals outlined in the Periodic Maintenance Chart beginning on page 48. Do not obstruct or deflect air flow through the radiator by installing unauthorized accessories in front of the radiator or behind the cooling fan. Interference with the radiator air flow can lead to overheating and consequent engine damage.

NOTICE: Washing the vehicle with a high-pressure hose could damage the

radiator fins and impair the radiator's effectiveness. Using a highpressure system is not recommended.

MAINTENANCE

Cooling System

Overflow Bottle Coolant Level

Always check and change the coolant at the intervals outlined in the Periodic Maintenance Chart beginning on page 48. Maintain the coolant level between the minimum and maximum marks on the bottle (when the fluid is cool).

The overflow bottle is located in front of the right front wheel.

1. Position the vehicle on a level surface.

2. View the coolant level in the overflow bottle.

3. If the coolant level is below the safe operating range, lift the hood and locate the overflow bottle lid. Remove the cap and use a funnel to add coolant through the filler opening. Reinstall the cap.

Tip: If coolant must be added often, or if the overflow bottle runs completely dry ,

there may be a leak in the system. Have the cooling system inspected by your Polaris dealer.

5. Reinstall the pressure cap. Use of a non-standard pressure cap will not allow the recovery system to function properly. See your dealer for the correct replacement part.

MAINTENANCE

Polaris Variable Transmission (PVT) System

Failure to comply with the instructions in this warning can result in severe injury or death.

Do not modify any component of the PVT system. Doing so may reduce its strength so that a failure may occur at a high speed. The PVT system has been precision balanced. Any modification will cause the system to be out of balance, creating vibration and additional loads on components.

The PVT system rotates at high speeds, creating large amounts of force on clutch components. Extensive engineering and testing has been conducted to ensure the safety of this product. However, as the owner , you have the following responsibilities to make sure this system remains safe:

• Always follow all recommended maintenance procedures. See your dealer as outlined in the owner's manual.

• This PVT system is intended for use on Polaris products only . Do not install it in any other product.

• Always make sure the PVT housing is securely in place during operation.

When To Use Low Range vs. High Range

Belt slip is responsible for creating excessive heat that destroys belts, wears clutch components and causes outer clutch covers to fail. Switch to low range while operating at slower speeds to extend the life of the PVT components (belt, cover, etc.).

Condition Range to Use

Operating at speeds less than 7 MPH (11 km/h) Low Towing heavy loads Low Operating in rough terrain (swamps, mountains, etc.) Low Operating at speeds greater than 7 MPH (11 km/h) High

Brake Fluid

Inspect the brake system routinely. Inspect the level of the brake fluid before each operation.

WARNING! After opening a bottle of brake fluid, always discard any unused portion. Never store or use a partial bottle. Brake fluid is hygroscopic, meaning it rapidly absorbs moisture from the air. The moisture causes the boiling temperature of the brake fluid to drop, which can lead to early brake fade and the possibility of accident or severe injury.

Change the brake fluid every two years and any time the fluid becomes contaminated, the fluid level is below the minimum, or if the type and brand of the fluid in the reservoir are unknown. See page 53 for fluid recommendations.

1. Position the vehicle on a level surface.

2. View the brake fluid level at the

reservoir in the driver’s side wheel well. The level should be between the upper (MAX) and lower (MIN) level lines.

Chrome Wheel Care (if equipped)

Proper maintenance will protect chrome wheels from corrosion, preserve wheel life and ensure a “like new” appearance for many years. Chrome wheels exposed to road salt (or salt in the air in coastal areas) are more susceptible to corrosion if not properly cleaned. Clean chrome wheels more often if they're exposed to salt or other corrosive elements.

1. Was h chrome wheels frequently. Use a mild detergent. Never use abrasive cleaners on plated or painted surfaces.

2. Rinse well with clear water. Soap, detergents, salt, dirt, mud and

other elements can cause corrosion.

3. Polish the clean chrome wheels periodically. Use an automotive

grade chrome polish.

4. Routinely and liberally apply a weather resistant wax to each pol-

ished chrome wheel. Choose a product suitable for chrome finishes. Read and follow the product labels and instructions.

Removing Corrosion

If light rust is found on the chrome finish, use steel wool (#0000-OTT grade) to remove it. Gently rub the affected areas with the steel wool until the corrosion has been removed. Clean and polish the wheel as outlined above.

Inspect the fluid levels. Add or change fluids as recommended in the Periodic Maintenance Chart beginning on page 48.

• Front and rear gearcase fluid (if equipped)

• Transmission fluid

• Brake fluid (change every two years and any time the fluid looks dark or contaminated)

• Coolant (test strength/fill)

Fog the Engine

1. Remove the spark plug and add 2-3 tablespoons (30-45 ml) of

engine oil.

2. Reinstall the spark plug. Torque to specification. See page 62.

3. Apply dielectric grease to the inside of the spark plug cap. Reinstall

the cap.

4. Turn the engine over several times. Oil will be forced in and around

the piston rings and ring lands, coating the cylinder with a protective film of fresh oil.

5. Treat the fuel system with Polaris Carbon Clean. See page 95. If

Polaris fuel system additive is not used, fuel tank, fuel lines, and carburetor should be completely drained of gasoline.

6. To eliminate any fuel remaining in the carburetor, run the engine

until it stops.

Storage Area/Covers

Be sure the storage area is well ventilated. Cover the vehicle with a genuine Polaris cover. Do not use plastic or coated materials. They do not allow enough ventilation to prevent condensation, and may promote corrosion and oxidation.
