OPERATION
Fuel
For peak performance, Polaris recommends the use of 91 octane or
higher fuel. Although 87 octane fuel is usable, some engine perfor-
mance will be lost and fuel economy will decrease. Do not use lower
than 87 octane fuel. Do not use fuel containing more than 10% ethanol
(including E85).
NOTICE: Operating with obstructed fuel systems will result in serious engine
damage. Perform maintenance as recommended.
Damage to the fuel pump will occur if the snowmobile is operated with
an empty fuel tank. Do not allow the snowmobile to run out of fuel.
Always refuel when the level is low.
Prolonged exposure to petroleum based products may damage paint.
Always protect painted surfaces when handling fuel.
Fuel Mode Change Wires
This snowmobile is equipped with a feature that allows you to select the
proper calibration map for the fuel available in your region. The fuel
mode change wires are located in the wiring harness secured to the rear
underside of the clutch guard behind the console. The disconnected
mode change wires must be connected when non-ethanol fuel is used.
NOTICE: Engine damage may occur if ethanol fuel is used after setting up the
vehicle for non-ethanol fuel use. Depending on your model, always
disconnect the mode change wires before operating with ethanol fuel.
When in doubt about fuel quality, always unplug the wires.
Ethanol fuel: Leave the wires
UNPLUGGED when using oxygen-
ated fuel containing up to 10% etha-
nol. Never use E85 blended fuel.
Non-ethanol fuel: CONNECT the
black/blue wires to the pink wire
when using non-ethanol blended
fuel.
