FEATURES AND CONTROLS
Block Heater
To improve cold-weather starting, a block heater has been installed on
the engine of your snowmobile. When connected to a 110V electrical
outlet, the block heater warms the engine, making it easier to start in
subzero temperatures. We recommend the use of this block heater
whenever temperatures drop below --20° F. (--30° C.).
Open the hood to access the block heater plug-in (see page 29 for
location). Plug the cord into a 110 V outlet when the snowmobile will
be parked in subzero temperatures overnight or for more than a few
hours. Unplug the cord and return it to its storage area before starting
and operating the snowmobile.
Driving the snowmobile before unplugging the block heater could
result in damage to the heater and other components. Always
unplug the block heater before operating the snowmobile.
