MAINTENANCE

Tires

Operating your vehicle with worn tires will increase the possibility of skidding, 
loss of control and an accident, which could result in serious injury or death. 
Always replace tires when the tread depth measures 1/8” (3 mm) or less.
Improper tire inflation or the use of non-standard size or type of tires may 
adversely affect vehicle handling, which could result in vehicle damage or 
personal injury. Always maintain proper tire pressure.. Always use POLARIS-
approved size and type of tires for this vehicle when replacing tires.

Tire Tread Depth

Always replace tires 
when tread depth is 
worn to 1/8" (3 mm) or 
less.

MAINTENANCE

Lights

Headlight and taillight lenses become dirty during normal operation. 
Clean all lights frequently to ensure a clear field of vision as well as vis-
ibility to other vehicles.

When servicing a halogen lamp, don't touch the lamp with bare fingers. 
Oil from your skin leaves a residue, causing a hot spot that will shorten 
the life of the lamp.

LED Headlamps (if equipped)

If a headlight becomes damaged or inoperable, the entire headlight 
assembly must be replaced.

Tip: If an LED headlamp has moisture or fogging inside, disconnect the wiring 

harness from the headlamp(s) for a few days to allow the moisture to clear 
out. Do not operate the vehicle at night or in low light conditions without 
properly working headlights.

Headlight Lamp Replacement

Do not service the headlamps until they've cooled sufficiently.

1. Unplug the headlamp from 

the wiring harness. Be sure 
to pull on the connector, 
not on the wiring.

2. Turn the lamp counter-

clockwise to remove it.

3. Install the new lamp. Make 

sure the tab on the lamp 
locates properly in the 
housing.

4. Reinstall the harness 

assembly into the headlight 
assembly.

Headlight Beam Adjustment

1. Place the vehicle on a level surface with the headlight 

approximately 25 ft. (7.6 m) from a wall. Place the transmission in 
PARK.

2. Measure the distance from the floor to the center of the headlight 

and make a mark on the wall at the same height.

3. Apply the brakes. Turn the ignition switch to the LIGHTS ON 

position.

4. Observe the headlight aim. The most intense part of the headlight 

beam should be aimed 8" (20 cm) below the mark placed on the 
wall in step 2. Include the weight of a rider on the seat while 
performing this step. 

5. If adjustment is necessary, turn the headlight adjustment screw to 

adjust the beam.

6. Repeat steps 4-5 until the beam is properly adjusted.
