Washing the Vehicle

Keeping your POLARIS vehicle clean will not only improve its 

appearance but it can also extend the life of various components.
Before washing the vehicle, locate the CVT inlet and outlet ducts and 

the air box. The ducts are located under the rear wheel wells. Avoid 

spraying water directly toward the ducts or air box when washing the 

vehicle from the rear.

NOTICE:

 

Water in the CVT system could cause the drive belt to become wet 

and slip in the clutches. Always avoid spraying water directly toward 

the CVT inlet and outlet ducts when washing the vehicle from the 

rear.
High water pressure may damage components. POLARIS 

recommends washing the vehicle by hand or with a garden hose, 

using mild soap. 
Certain products, including insect repellents and chemicals, will 

damage plastic surfaces. Do not allow these types of products to 

contact the vehicle.

Cleaning and Storage

Washing the Vehicle

The best and safest way to clean your POLARIS vehicle is with a 

garden hose and a pail of mild soap and water. 
1. Use a professional-type washing cloth, cleaning the upper body

first and the lower parts last.

2. Rinse with clean water frequently.
3. Dry surfaces with a chamois to prevent water spots.

Washing Tips
• Avoid the use of harsh cleaners, which can scratch the finish.
• Do not use a power washer to clean the vehicle.
• Do not use medium to heavy duty compounds on the finish.
Always use clean cloths and pads for cleaning and polishing. Old or 

reused cloths and pads may contain dirt particles that will scratch the 

finish.

MAINTENANCE

Cleaning and Storage

Washing the Vehicle

If a high pressure water system is used for cleaning (not 

recommended), exercise extreme caution. The water may damage 

components and could remove paint and labels. Avoid directing the 

water stream at the following items: 
• Wheel bearings
• Transmission seals
• CVT inlet and outlet ducts
• Air  box
• Brakes
• Cab and body panels
• Labels and decals
• Electrical components and wiring
If an informational or graphic label becomes illegible or comes off, 

contact your POLARIS dealer to purchase a replacement. 

Replacement safety labels are provided by POLARIS at no charge.
Grease all zerk fittings immediately after washing. Allow the engine 

to run for a while to evaporate any water that may have entered the 

engine or exhaust system.

Polishing the Vehicle

POLARIS recommends the use of common household aerosol 

furniture polish for polishing the finish on your POLARIS vehicle. 

Follow the instructions on the container.
Polishing Tips
• Avoid the use of automotive products, some of which can scratch 

the finish of your vehicle.

• Always use clean cloths and pads for cleaning and polishing. Old or 

reused cloths and pads may contain dirt particles that will scratch 

the finish.

Storage Tips

NOTICE: Starting the engine during the storage period will disturb the 

protective film created by fogging and damage could occur. Never 

start the engine during the storage period.

Clean the Exterior
Make any necessary repairs and clean the vehicle as recommended. 

See page 93.
Stabilize the Fuel
1. Fill the fuel tank.
2. Add POLARIS Carbon Clean Fuel Treatment or POLARIS Fuel

Stabilizer or equivalent fuel treatments or stabilizers. Follow the

instructions on the container for recommended amount. Carbon

Clean removes water from fuel systems, stabilizes fuel, and

removes carbon deposits from pistons, rings, valves, and exhaust

systems.

3. Allow engine to run 15-20 minutes to allow stabilizer to disperse

through entire fuel system.

Air Filter / Air Box
Inspect and clean or replace the air filter. See page 76. Clean the air 

box. Drain the sediment tube.
Fluid Levels
Inspect the fluid levels. Add or change fluids as recommended in the 

Periodic Maintenance Chart beginning on page 57.
• Transmission fluid
• Brake fluid (change every two years and any time the fluid looks

dark or contaminated)

Engine Oil
Change the oil. See page 66.
