MAINTENANCE

Engine Oil

Always check the oil level daily. Change the engine oil at the intervals outlined in the
Periodic Maintenance Chart beginning on page 73. Always change the oil filter whenever
changing oil.
WARNING! Vehicle operation with insufficient, deteriorated or contaminated engine oil will cause
accelerated wear and may result in engine seizure, accident and injury. Always perform the
maintenance procedures as outlined in the Periodic Maintenance Chart.
Oil Recommendations
NOTICE: Use of a non-recommended engine oil may cause serious engine damage.
POLARIS recommends the use of POLARIS Diesel Oil (SAE CI-4) for this vehicle. Always

Oil Check
The oil dipstick is located on the engine under the
passenger seat.
Tip: Engine oil should be checked cold or allow time for the
oil to drain back into pan before checking to prevent
overfilling.
1. Position the vehicle on a level surface.
2. Stop the engine.
3. Tilt the rear cargo box to access the engine oil
dipstick.
4. Remove the dipstick. Wipe it dry with a clean
cloth.
5. Reinstall the dipstick, then remove it and check the
oil level. Maintain the oil level in the safe range.
Do not overfill.
Tip: Due to the dipstick entry angle into the crankcase, the oil
level will read higher on the bottom side of the dipstick.
Always read the level on the upper surface of the
dipstick.
