OPERATION
Fuel
Polaris recommends the use of 91 octane or higher fuel. Although 87
octane fuel is usable, some engine performance 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. Prolonged expo-
sure to petroleum based products may damage paint. Always protect
painted surfaces when handling fuel.
This snowmobile is equipped with a feature that allows you to select the
proper calibration map for the fuel available in your region. Fuel resis-
tors must be changed (600 models) or the disconnected mode change
wires in the wiring harness must be connected (800 models) 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
reinstall the ethanol fuel resistor or disconnect the mode change wires
before operating with ethanol fuel. When in doubt about fuel quality,
always use the ethanol fuel resistor or unplug the wires.
Fuel Resistor (600 Models)
On 600 cc models, the factory-installed
fuel resistor is for the use of ethanol fuel. If
operating with non-ethanol fuel becomes
necessary, always install the non-ethanol
fuel resistor. The non-ethanol fuel resistor
is provided in the tool kit.
Fuel Mode Change Wires (800 Models)
On 800 cc models, fuel mode change
wires are located in the wiring har-
ness secured to the rear underside of
the clutch guard behind the console.
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.
