Engine Management System
The engine management system is programmed to alert the rider when
coolant temperatures reach higher-than-normal levels. The system
responds by taking the following sequential steps to alert the rider.
1. The High Temperature Indicator on the MFD will flash.
To cool the engine, drive the snowmobile into soft snow so that it comes
into contact with the heat exchangers on the snowmobile. Alternately,
you can stop the snowmobile and pack snow or ice onto the heat
exchangers to bring the temperature of the engine down.
2. The High Temperature Indicator on the MFD will flash and the
engine will misfire or "stutter".
If you do not notice the flashing indicator on the MFD or do not suffi-
ciently cool the snowmobile, the engine will misfire to alert you to look
at the MFD and take action. Again, driving the snowmobile into soft
snow or packing snow onto the heat exchangers should cool the engine.
3. The engine will stop.
If the engine reaches an extreme temperature where damage becomes
possible, the system will stop the engine. This condition will occur only
after the system has taken both previous steps to alert the rider to the
extreme engine temperature. If the engine stops and you attempt to
restart it while before it has cooled sufficiently, the engine will restart
and run for two seconds but will immediately stop again.
Tip: The engine management system will also turn the engine off if the engine
reaches an extreme temperature while idling.
