Fuel Type Selection

Whenever using ethanol, MTBE or other forms of oxygenated gaso-
lines, the fuel type designation setting must be changed to “Eth” in the 
gauge. When using the recommended 91 non-ethanol gasoline, always 
select the “91-non” setting.

Whenever in doubt of your fuel 
purchase, use the “Eth” setting as 
a safeguard.

Use the following procedure to 
change the fuel type designation in 
the gauge. Refer to the fuel type 
selection label located inside the 
left side panel.

1. Start the engine.

2. Lock the parking brake.

3. Press and release the 

SELECT button or SET 
switch until “FUEL” is dis-
played in the lower section of 
the gauge.

4. Press and hold the SELECT button or SET switch until the desired 

fuel type is displayed in the center of the screen.

FEATURES

Detonation Elimination Technology (DET)

The DET system prevents damage to the engine from detonation by 
going into an engine protection mode whenever the DET system is 
active.

When excessive detonation is detected, 
the check engine light will illuminate 
and you may notice decreased engine 
performance and RPM when the DET 
system is activated. In most cases this 
is temporary and the operator does not 
need to take any action. The engine 
will return to its normal performance 
automatically.

If severe detonation occurs, the check engine light will begin to flash 
steadily and the gauge indicator will read “dET” (see illustration). The 
engine will enter a limp home mode and RPM will be limited to 6500 
RPM. The engine will remain in this mode until it is shut down and 
restarted.

DET Troubleshooting

Security System (Ignition Lock System)

Your snowmobile has an optional security function that can be activated 
by an authorized POLARIS dealer. If you have this feature activated, 
you can lock the ignition to prevent unauthorized use when leaving the 
snowmobile unattended. A locked system will limit engine speed to 
3000 RPM, which prevents clutch engagement, and the snowmobile 
will not move when throttle is applied.

If you wish to use this system, see page 37 of the Instrument Cluster 
section for security system activation and operating instructions.
