Snowmobile Polaris 600 Switchback / 800 Switchback (2013 year). Manual - part 7

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.

Indicators

Check Engine Indicator

This indicator appears if an EFI-related fault occurs. Do not operate the 
snowmobile if this warning appears. Serious engine damage could 
result. See your dealer. See page 44 for diagnostic code definitions.

Over-Temperature Indicator

This indicator illuminates to alert the operator that the engine is over-
heating. The operator should take action to cool the engine. See page 92. 
If the indicator flashes, continued operation could result in serious 
engine damage. Stop the engine immediately.

Low Oil Indicator

The low oil indicator light may flicker at times due to oil movement in 
the bottle, but when the light comes on and remains on, add the recom-
mended oil before further operation. See page 73.

High Beam Indicator

The high beam indicator illuminates when the lights are set to high 
beam.

Parking Brake Indicator

This indicator illuminates when the parking brake is engaged. It will 
also illuminate when the service brake is in use. See page 64.
