7) Tether Cut-Out System
General
The tether cut-out system serves 3 functions.
It prevents snowmobile runaway if the operator accidently falls off
shutting off the engine.
Through the DESS (Digitally Encoded Security System), it acts as a
lock by preventing unauthorized use of your snowmobile thus deter-
ring theft.
Finally, it prevents unintentional electric starter operation on vehicles
so equipped by disabling the electric starter and ignition circuits in
the MPEM.

WARNING
Always disconnect tether cord when leaving vehicle unattent-
ed and keep in a secured location.
