OPERATION

Driving on Slippery Surfaces

When driving on slippery surfaces such as wet trails, loose gravel, 

sand or ice, be alert for the possibility of skidding and sliding.
Follow these precautions when driving in slippery conditions:
1. Slow down before entering slippery areas.
2. Be alert, watch the path ahead and avoid quick turns, which can 

cause skids.

3. Correct a skid by turning the steering wheel in the direction of the 

skid. Never apply the brakes during a skid.

OPERATION

Driving Uphill

Whenever traveling uphill, follow these precautions:
1. Always check the terrain carefully before ascending a hill. Never 

drive on hills with excessively slippery or loose surfaces.

2. Avoid excessively steep hills (15° maximum).
3. Drive straight uphill.
4. Drive at a steady rate of speed. Never press the throttle suddenly.
5. Avoid unnecessary changes in speed or direction.
6. Never go over the crest of a hill at a high speed. An obstacle, a 

sharp drop, or another vehicle or person could be on the other side 

of the hill.

7. If the vehicle stalls while climbing a hill, apply the brakes. Place 

the transmission in reverse and slowly allow the vehicle to roll 

straight downhill while applying the brakes lightly to control 

speed.

15° maximum

OPERATION

Driving on a Sidehill (Sidehilling)

Driving on a sidehill is not recommended. Driving on a sidehill 

improperly cause loss of control or rollover.
If crossing a hill is unavoidable, follow these precautions:
1. Drive slowly and use extreme caution.
2. If the vehicle begins to roll over, or if it feels as if it may roll over, 

immediately turn downhill.

3. Avoid obstacles and changes in terrain that may lower or raise one 

side of the vehicle or cause the vehicle to slide.

4. If the vehicle begins to slide downhill, immediately turn downhill 

to stop the slide, or stop the vehicle and maneuver slowly and 

carefully until the vehicle can be driven straight downhill.

Driving Downhill

Whenever driving down a hill, follow these precautions:
1. Avoid excessively steep hills (15° maximum).
2. Slow down. Never travel down a hill at high speed.
3. Always check the terrain carefully before driving down a hill. 

Never drive on hills with excessively slippery or loose surfaces.

4. Always drive down a hill with the transmission in forward gear. 

Never “coast” or drive down a hill with the transmission in 

neutral.

5. Avoid driving down a hill at an angle, which would cause the 

vehicle to lean sharply to one side. Always drive straight 

downhill.

6. Apply the brakes lightly to keep speed slow.

OPERATION

Driving Through Water

Your vehicle can drive through shallow 

water. Make sure the water is no deeper 

than the floor of the vehicle. Follow 

these precautions when driving through 

water:
1. Check water depth. Never drive 

through water that is deeper than 

the floor level.

2. After driving through water, test 

the brakes. Apply them lightly 

several times while driving slowly. 

The friction will help dry out the 

pads.

NOTICE: Major engine damage can result if 

the vehicle is not thoroughly inspected after operation in water. 

Perform the services outlined in the maintenance chart. See page 

57. Give special attention to engine oil, transmission oil and all 

grease fittings.
If your vehicle becomes immersed or is operated in water that 

exceeds the floor level, service is required before starting the 

engine. Your POLARIS dealer can provide this service. If it's 

impossible to bring the vehicle in before starting the engine, perform 

the service outlined on page 86, and take the vehicle in for service 

at the first opportunity.
